2 PHYSICAL DESCRIPTION AND THEORY OF OPERATION
2.1 Principle of Operation
2.1.1 RM-1200/BMSC
The RM-1200/BMSC Remote Monitor is an electronically controlled power
regulator and visual status indicator designed to operate in conjunction with
multiple bi-polar ionization generators. The RM-1200/BMSC is used to
simultaneously regulate the output and individually monitor the operating
status of up to six (6) power generators in a system.
The heart of the RM-1200/BMSC is an integrated six (6) channel electronic
fault detection and alarm circuit board. This board closely monitors the
ionization level of the generator by comparing a voltage derived sensing
signal with a preset LED circuit. The result is real-time status monitoring of
ionization voltage across all tubes in the generator.
The RM-1200/BMSC Remote Monitor is an entirely self-contained unit
designed for wall or surface mounting. Electronic circuitry and power
regulation devices together with associated ionization level control and visual
status indicators are all housed within a NEMA 1 enclosure.
The RM-1200/BSMC has three operating ranges, "Under", "Normal" and
"Overload". Each range is adjusted within certain limits of ionization as set
by the level control on the front panel. As the ionization control is advanced
(turned up), ionization increases and the status indicators will switch in
sequence from Under (Amber) to Normal (Green) to Overload (Red), thus
providing a visual indication of output level. Since the level control is
continuously variable, system operators are free to make level changes within
each operating range depending upon environmental or other operating
considerations.
In a typical operating system, all Green LED’s are normally illuminated and
fault relay contacts are open. (no fault condition) In the event of a power
failure, component failure, fuse failure, or if the panel mounted gain control
is set too low, the Amber LED will illuminate and the fault relay will close its
contacts to the outside world. In the event of a catastrophic power failure,
one which shuts down the entire system, the external fault relay contacts
remain closed, thus providing fail safe operation. A short circuit within the
power generator circuit caused by an arcing ionization tube will normally
produce an “overload” condition. The corresponding local red LED will
illuminate and the external fault alarm contact will again close. Only in the
green normal range of operation is the external fault alarm cleared.
2.1.2 Building Management System Control (BMSC)

RM-1200/BMSC - I, O, & M Manual
Page 7
BMSC permits power operational control from any remote location.
Included are the following functions:
• “On/Off” control of System power
• Selection of 75% or 100% power output
• Visual indication of ionization level (using discrete alarm contacts)
2.2 Front Panel Controls and Indicators
Refer to Appendix A
Front Panel Controls & Indicators – description and functions
2.2.1 Ionization Status Lamps
The RM-1200/BMSC monitors each generator simultaneously with a bank of
three status lamps.
The three LED lamps marked Under (Amber), Normal (Green), and
Overload (Red) indicate three operating conditions. All generators in the
system operate in response to the position set by the ionization level control.
Each setting is calibrated at the factory within specified limits as shown in
TABLE 1.
The Normal (Green) range is recommended for all standard ionization
applications. Both the Under (Amber) and Overload (Red) indices represent
abnormal operating conditions; hence they are referred to as "faults".
TABLE 1
Indicator Ionization
Range Light Tube Potential Operating
Indication Color VAC(rms) 60Hz Condition
Under(fault) Amber 1250 to 1750 Negligible ionization
Norm Green 1800 to 2350 Normal ionization
Overload(fault) Red 2400 to 2500 High voltage, Ozone potential
2.2.2 System Fuse
This is main system fuse is located on the front panel. It protects the RM-
1200/BMSC power control circuitry and the electric service feeding all
generators in the system. DO NOT substitute or jump this fuse. Replace
only with the exact type provided by Bioclimatic.

NOTE: Use AGC type fast acting fuse only. FLA ratings based on average current
estimates using “F” type Ionization tubes.
2.3 Internal Equipment and Connections
Refer to Appendix B
Internal Equipment and Connections – description and functions
3 INSTALLATION
3.1 Initial Setup
3.1.1 Aerotron Bi-Polar Ionization Units
Unregulated Aerotron units are designed for installation totally within the
plenum of an air handling unit.
Install ionization tubes as follows:
3.1.1.1 Screw tubes into socket by holding the leaf spring clear of the tube
surface.
3.1.1.2 Turn tube into socket by the plastic base.
3.1.1.3 After tube contacts base, tighten an additional 1/8 to ¼ turn. Do not
hand tool to tighten tubes, as they will damage the glass tubes.
3.1.1.4 Ensure leaf spring is in contact with outer mesh.
3.1.1.5 Close access door.
Note: The ionization tubes are fragile - Handle With Care.
3.1.2 RM-12 00/BMSC Unit
The RM-1200/BMSC may be mounted directly on the air duct or side access
housing in which the power generators are installed. The internal wiring
necessary to interconnect the RM-1200/BMSC to the operating units may
then be brought directly to the wiring terminal block located inside the front
panel (door). Power entrance and internal wiring are brought through the
two ports in the enclosure.
The RM-1200/BMSC may also be mounted remotely from the power
generators such as on an adjacent wall provided the maximum distance
between the remote monitor and the last generator within the duct system
does not exceed 50 feet. Installations that require greater distances can be
accommodated, however special wiring is required. Such installations must
be referred to Bioclimatic Engineering Department prior to installation.
WARNING!! The RM-1200/BMSC is only designed for installation
within a weather-protected and air-conditioned space. NEVER install

RM-1200/BMSC - I, O, & M Manual
Page 9
the RM-1200/BMSC outdoors or in any location not covered by Section
6 (SPECIFICATIONS) of this manual.
3.2 Electrical Connections
Refer to Appendix C, drawing #30478, Revision A. The RM-1200/BMSC is
designed to operate from 115/220 V, 50/60 Hz, single phase AC. All electrical
connections to AC main voltage are made on Terminal Block, TB 1, located behind
the front door panel. Terminals 1, 2, and 3 are provided for standard line, neutral,
ground connections respectively. The remaining connections are shown. Remove
the access cover from RM-1200/BMSC exposing the main termination blocks
marked TB1 and TB2. All electrical connections to and from the RM-1200/BMSC
are made at TB1 and TB2.
The regulated power output lines to the ionization generators are Output 1 (terminals
TB1-8-10), Output 2 (terminals TB1-11-13), and Output 3 (terminals TB1-14-16).
While all three outputs are essentially in parallel and all controlled by the setting of
the level control on the front panel, it is important to distinguish between each output
in terms of total load current and the number of generators and their types in the
system. It is important for proper system operation that load currents be equally
distributed between the output lines in use. DO NOT integrate connections of
dissimilar generators on any single output port. It is further recommended that no
more than four generators be connected to any one output terminal. TABLE 2 below
shows the proper way to connect the generators to provide the proper load
distribution for each regulated output port.

Primary power is brought inside the unit through an access hole located on the lower
left side of the RM-1200/BMSC enclosure. (The punch-out will accommodate
appropriate connectors for either ½” (13 mm) EMT or ½” (13 mm) flexible metal
conduit. Wiring must be in accordance with all applicable national electrical and

RM-1200/BMSC - I, O, & M Manual
Page 10
local wiring codes. Also, located on the left side of the enclosure is a ¾” dia. hole
with grommet designed to accommodate a multi-conductor cable for connection to
the fault alarm terminals.
WARNING!! Do not attempt to connect the RM-1200/BMSC to electrical
service unless you are qualified to do so. Electrical connections must be
performed by a licensed electrician, or other qualified personnel.
Multiple bi-polar ionization generators (up to 6) may be connected to a single RM-
1200/BMSC. The regulated power wiring fed to the generators must conform to
applicable codes specified by NFPA/NEC, (wiring in ducts, plenums and other air
handling spaces) when the generator units are installed inside a Side Access Housing
or other enclosed air handling unit plenum.
3.2.1 TB1 & TB2 Connections for Fault Alarm Options
Refer to Appendices D and E for Discrete Channel fault alarm and
Single Station fault alarm options for the RM-1200/BMSC.
The connection terminals on TB1 and TB2 are designed to accommodate up
to 14-gauge stranded electrical wire. Primary connections to electric service
are made at TB1, terminals L, N & G. These terminals correspond
respectively to Line (L), Neutral (N) and Ground (G) in Standard 125V, 1φ,
3W grounding systems and Line 1 (L1), Line 2 (L2) and around (G) in 240V,
1φ, 3W ground systems.
CAUTION: DO NOT attempt to connect the RM-1200/BMSC across
multi-phase (3 or 4 wire circuits) or across any electrical service in
which pole to pole voltage exceeds 240 Volts rms.
Carefully strip insulation 3/8-inch from ends. Twist strands evenly and insert
wire into the access hole opened by pressing down on the slotted tab using a
small screwdriver. Releasing the tab will clamp wire securely in place.
Terminals marked "G" are common ground and should be externally tied to
common system ground. Ground faults must not exist between these two
ground terminals.
Run a separate line (20 AWG stranded wire) from each Aerotron generator
terminal to the corresponding terminals of TB1 and TB2; e.g. for a RM-
1200/BMSC discrete channel fault alarm, generator #1 should be connected
to TB1-21 (#1 sense line), generator #2 to TB1-24 (#2 sense line), etc.
3.2.2 TB3 Connections for BMS Power Control
Refer to Appendix B and C.
The connection terminals on TB3 are designed to accommodate up to 16
gauge stranded electrical wire. Connections for Remote Monitor “On-Off”

RM-1200/BMSC - I, O, & M Manual
Page 11
4 SYSTEM START UP
are made at TB3 terminals 2 and 3. Terminals 3, 4 and 5 are made for
selector switch.
After the power connections and generator sense lines have been secured at TB1 and TB2
and all generators in the system have been connected, proceed as follows:
Place the system master on-off switch in “off” position. Rotate keylock switch and open
panel door. Determine that a 1 amp AGC fuse is in the power supply receptacle. Inspect all
wiring for loose connections or broken wires. Observe selector switches position on the
selector switch board (refer appendix B). Top switch (S3) turn to “Local”. Bottom switch
(S4) turn to “1-6”. Close and lock the front panel door.
Note: The keylock switch is a safety feature, which removes all power to the RM-
1200/BMSC in the unlocked position. Power is only supplied to the unit when the front
panel door is closed and locked.
Inspect the main system fuse. The fuse rating has been selected based on total system power
consumption. Its value depends upon the number of ionization tubes operating in the
system. The proper fuse has been installed at the factory. Replace with only the same type
of fuse. DO NOT SUBSTITUTE.
CAUTION!!! DO NOT energize the system without installing ionization tubes.
Start the system by pressing the power button.
Slowly, advance the gain control clockwise until the Green ionization status lamps
illuminate. Check the range of this control and observe the point on the circular scale where
the light switches to Under (Amber) and Overload (Red). These two switch points should
correspond to dial settings of approximately 9 o'clock and 3 o'clock, respectively.
Finally, the gain control can be set to any position, within any of the "Green" ranges
consistent with environmental requirements. The power regulator circuit in the RM-
1200/BMSC will maintain correct operating conditions for all system generators. All
generators, when functioning normally, will display identical range indication
regardless of the power control setting.
4.1 Operating System Gain Control
The system gain control is used to regulate the primary input voltage to the entire
bank of power generators. When the gain control is rotated fully counterclockwise,
minimum ionization occurs. When the gain control is rotated fully clockwise,
maximum ionization occurs. The gain control acts to control the amount of
ionization in the system much the same as the volume control on a radio controls the
amount of sound.
The range of operation of the gain control is adjusted at the factory so that the LED
indicators provide a visual display of the exact operating condition. Turning the
control fully clockwise results in illumination of all red LED indicators (overload).

RM-1200/BMSC - I, O, & M Manual
Page 12
Conversely, setting the gain control fully counterclockwise reduces system ionization
to a minimum value (under). The operating range between these two limits (normal)
is shown by green LED indicators. The green or “normal” range is the acceptable
region of operation. It is not recommended that the system be operated in either the
low ionization (amber) or overload (red) condition. These two modes are fault
modes and alarms will be initiated instantly when the system is manually set to either
mode or else defaults automatically through system component failures. Refer to
TROUBLESHOOTING (Section 5.3).
4.2 Setting the BMSC
Refer to Appendix A and B
Turn the top switch (S3) on selector switch board (SSB) to the “BMS” position. The
indicator lights will illuminate on the SSB and front panel door (when system master
illuminated power switch and keylock switch are in “on” position) to indicate the
remote monitor is ready to be operated by BMS.
5 OPERATION & MAINTENANCE OF UNIT
5.1 General
In the event difficulty is experienced in regulating any or all of the operating levels
on the generators, there are a few tests that can be performed to determine the
problem. Remember, the front panel lamp display field is only intended to detect
and identify generator problems. It cannot diagnose the nature of any such related
problem, only that a particular generator has a fault, either overload or under
ionization. In the event your system is connected to an external building
management system or other external monitoring system, any locally originated
faults will be transmitted by relay contact closure to prompt the external system to
display a fault condition. Locally, the respective channel LED indicator will also
illuminate on to flag the particular problem generator and display the type of fault.
Users are reminded that the RM-1200/BMSC initiates no “signal voltage”. Instead,
it provides a dry contact closure that must be connected through suitable interface to
any building management system.
Once a fault has been detected and the problem generator is identified, there are a
few simple checks that can be performed to further identify the nature of the
problem. Each of the power generators in the system is numerically identified as to
its physical location in the duct or plenum by the front panel marking “generator
number 1 through 6”. Observe that each power generator is provided with two small
pin type test jacks mounted on the side of the housing. These jacks are connected
internally across the low side of the high-voltage resistive divider circuit. The small
voltage present at these jacks measures within a range of 1.3 volts to slightly greater
than 3.0 volts AC. The voltage is normally measured directly to these test jacks on
each generator using any AC/DC multi-meter set to the 0-10 AC volt range. The
voltage reading is indicative of the general operation of the ionization generator.

RM-1200/BMSC - I, O, & M Manual
Page 13
The following test procedure is recommended as the initial step in trouble shooting
the system, or for tracking down a faulty generator.
5.1.1 Rotate the gain control fully counterclockwise.
5.1.2 Set voltmeter to 10 Volt AC range (other ranges are acceptable as well)
5.1.3 Insert common test lead of voltmeter into black test jack of the power
generator to be tested.
5.1.4 Insert other test lead into red test jack.
5.1.5 Read the AC voltage at the output of the test jacks. It should be in the
range of about 1.3 volts AC that is the lowest setting. Record this voltage
reading.
5.1.6 Rotate the gain control fully clockwise and again measure and record the
voltage present at the test jacks. It should be approximately 3.0 Volts AC.
This is the maximum setting for the unit.
The AC voltages obtained at the output of the test jacks on the power
generators are also available inside the front door of the RM-1200/BMSC.
This convenient location allows all measurements to be made directly at
the same location as the gain control.
WARNING!!! THE FOLLOWING PROCEDURE WILL RESULT
IN EXPOSURE OF AC LINE VOLTAGE ACROSS POWER
SUPPLY TRANSFORMER, REGULATOR INPUT AND AT
LOCATIONS ON TB-1, WHEN THE DOOR IS OPENED AND
POWER SWITCH IS TURNED ON.
All measurements inside the RM-1200/BMSC must be performed by
qualified personnel only.
In order to measure individual channel voltage levels, unlock and open the
front door and locate the Phoenix connector blocks 1 through 6 located at the
bottom edge of the electronic PC board. Channel numbers are consecutive
from right to left. Refer to Appendix F, and Rear Side of front panel door.
Connect AC voltmeter between the ground terminal (green lead) and the
corresponding input pins on the respective terminal blocks as shown. Turn
locks witch on by rotating key 90 degrees. Energize system by turning
power switch on. Your readings at input pins 1-6 compare exactly to
voltages obtained at the corresponding test jacks.
5.2 Interpreting Test Results
Refer to Appendix G
After the voltage readings have been obtained and recorded, refer to the
accompanying drawing to determine the correct operation of the ionization
generator. Ionization (high) voltage is shown on the left vertical index ranging from
1250 through 2500 with corresponding test point values shown on the right vertical
index ranging from 1.35 to 2.83 Volts. Intermediate values corresponding to other
operating points for the ionization system are also shown.

RM-1200/BMSC - I, O, & M Manual
Page 14
A test point reading of 1.95 Volts for example corresponds to high voltage potential
of 1700 volts; 2.37 Volts corresponds to 2100 Volts, etc.
Also, note the conditions represented as “under”, “normal”, and “overload” spelled
out opposite the test voltages. These are factory-adjusted ranges of operation.
Continuous monitoring of test voltages is unnecessary. However, periodic checks
using the procedure outline above will provide assurance that all units are
functioning normally.If individual LED’s fall out of balance by more than 10%, or if
LED’s do not fire at their appropriate points, refer to the Troubleshooting Table in
this section.
5.3 Troubleshooting Guide
Under normal operating conditions, assuming the adjustments described in Section 5
(OPERATION & MAINTENANCE OF UNIT) have been made, all generators will
respond uniformly to changes in position or setting of the power control located on
the front panel of the RM-1200/BMSC. If the power control is set fully counterclockwise,
the Low (Amber) LED will light for each generator as selected by the
channel selector switch. As the power control is advanced in a clockwise direction,
the Normal (Green) LED will illuminate and the Amber light will extinguish.
Additional advancement of the control will eventually cause the High (Red) LED to
illuminate and Normal (Green) to extinguish.
Periodic inspection of the system generators is recommended to determine proper
operation. The following procedure is suggested.
5.3.1 Open the cover on RM-1200/BMSC and reduce the power control to
minimum (fully CCW).
5.3.2 Check the operation of the LED indicators, as the power control is rotated
through its 270 degree rotation from minimum setting to maximum setting.
5.3.3 Channels should respond in a similar manner with LED's switching at
approximately the same point for each channel as indicated in the following
diagram:
If all generators respond uniformly according to the above procedure,
then all generators are assumed to be operating normally.
The RM-1200/BMSC will detect and respond to a faulty ionization generator
by showing a non-uniform LED indication for the faulty generator. For
example, in a six-generator system, assuming a fuse is blown in generator
No. 4, the Low (Amber) LED will illuminate throughout the entire range of
the ionization gain control. Whereas, channels 1, 2, 3, 5 & 6 will all respond
uniformly as described in Step 4 above. Thus, the "non-uniform" or nonconforming
channel 4 generator is assumed to be defective.

RM-1200/BMSC - I, O, & M Manual
Page 15
The RM-1200/BMSC can be useful in establishing preliminary fault
conditions, as described above; however; it can not be relied upon to
determine the exact nature of the fault, only that a fault exists and in a
particular generator. This information however is sufficient to indicate the
need for further troubleshooting. To help provide a more detailed guide for
troubleshooting system problems, refer to the following table Section 5.4
(Troubleshooting Table), listing fault conditions, probable cause and
corrective action. Do not hesitate to contact the factory for assistance.

Notice: Corrective action must be performed by qualified personnel only. Refer to
manufacturer's recommended replacement procedures for ionization tubes.
5.5 Ionization tube maintenance
Periodically, ionization tubes should be washed to remove any surface dirt and restore
operating efficiency. Assuming the use of proper filtration, this maintenance should be
scheduled every six to twelve months depending on the application and the particle
filtration used. Remove ionization tubes by holding the leaf spring clear of the tube’s
external wire mesh and turn counterclockwise by holding the polycarbonate base. A
solution of warm water and non-abrasive detergent can be used to clean the tubes. A
soft nylon brush may be used to remove any embedded material within the external
