General functioning of the <strong>volume</strong> <strong>flow</strong> <strong>controller</strong><br />
The <strong>ecos416</strong> single-channel <strong>volume</strong> <strong>flow</strong> <strong>controller</strong> is a<br />
microprocessor-based, configurable <strong>volume</strong> <strong>flow</strong> <strong>controller</strong> used to<br />
control and regulate supply or return air <strong>volume</strong> <strong>flow</strong> boxes on the<br />
basis of LON ® technology. Individual, demand-led ventilation of<br />
individual rooms is possible in relation to the room occupancy, room<br />
temperature or the CO2 content of the air. The <strong>volume</strong> <strong>flow</strong> passing<br />
over the <strong>volume</strong> <strong>flow</strong> box is measured with an integrated static<br />
differential pressure sensor and is compared with the <strong>volume</strong> <strong>flow</strong><br />
setpoint specified by the <strong>controller</strong>. If the actual value deviates from<br />
the setpoint, the <strong>volume</strong> <strong>flow</strong> over the <strong>volume</strong> <strong>flow</strong> box is adjusted<br />
by means of the integrated damper drive until the required setpoint<br />
is attained. The inputs and outputs provided may be used for a<br />
variety of applications. The <strong>ecos416</strong> <strong>volume</strong> <strong>flow</strong> <strong>controller</strong> uses the<br />
LonTalk ® communication protocol and is LonMark ® -certified if the<br />
sensor profile (number 1) is used for the relevant input objects and<br />
if the actuator profile (number 3) is used for the relevant output<br />
objects. The <strong>ecos416</strong> intelligent unitary <strong>controller</strong> supports<br />
LonMark ® profile #8502, Space Comfort Controller - VAV.<br />
The integrated operating programme can be programmed freely<br />
with the help of a plug-in; it reads in the hardware and software<br />
addresses, processes the user programme, updates the outputs<br />
and handles the necessary communication with other stations in the<br />
network or with the management level. The user program can be<br />
loaded from any point in the LON ® network using<br />
SAUTER CASE LON Engine. The plug-ins can be used to<br />
parameterize the <strong>controller</strong>s with the SAUTER CASE LON Engine<br />
network management tool or via any LNS-based software,<br />
according to choice.<br />
Engineering notes<br />
Installation and wiring<br />
The <strong>volume</strong> <strong>flow</strong> <strong>controller</strong> can be fitted directly on the damper shaft<br />
of the <strong>volume</strong> <strong>flow</strong> box with the servo-motor. Another fixture on the<br />
housing of the <strong>volume</strong> <strong>flow</strong> <strong>controller</strong> functions as a counterbearing;<br />
this fixture is connected to the <strong>volume</strong> <strong>flow</strong> box.<br />
The plant devices are connected via screw terminals.<br />
The following conditions must be met:<br />
Cross-section<br />
conductors:<br />
LON network:<br />
of<br />
min. 0.82 mm 2 (AWG 18), max.<br />
2 mm² (AWG 13), compliant with<br />
standards and national installation<br />
regulations.<br />
min. 0.65 mm² (AWG 22), twisted and<br />
unscreened<br />
Suitable network terminations (terminators) must be used for<br />
different network topologies. Failure to comply with the specified<br />
requirements may cause transmission errors between the<br />
<strong>controller</strong>s. The use of different cable cross-sections in one network<br />
section is not permitted.<br />

Description of inputs and outputs<br />
The <strong>ecos416</strong> intelligent unitary <strong>controller</strong> has 4 universal inputs and<br />
2 universal outputs. 4 Triac outputs are also available. All the inputs<br />
and outputs must be configured via software. The input resolution is<br />
16 bits and the output resolution is 10 bits. The inputs and outputs<br />
may be used as follows:<br />
Input<br />
Temperature sensor:<br />
Potentiometer:<br />
Current:<br />
Voltage:<br />
Digital:<br />
Ni1000, NTC, Pt<br />
10 k, 100 k<br />
0…20 mA (4…20 mA)<br />
0…10 V<br />
Potential-free contact<br />
Output<br />
Voltage: 0…10 V=<br />
Digital:<br />
0…12 V= , (I/O)<br />
PWM<br />
The sampling period for the inputs is 1 s if they are configured as<br />
current, voltage, potentiometer or temperature inputs, and 500 ms<br />
for configuration as digital inputs. The UIx inputs can take a<br />
maximum load of 24 V.<br />
