STX Signal Transmitter Installation and Operation ... - Kistler-Morse

Chapter 8. MVS-STX Service Menu
E2rst (EEPROM reset)
(MVS only; does not apply to current
output on STX PCB)
This function resets the current output Mode
and the Iadj tuning parameters for 0 mA,
4 mA, and 20 mA to default values for all
channels on the displayed Current Output
PCB. The E2rst display looks like this:
DEFAULT ADDR 15?
F1 F2 F3
ADDR 15 is the Current Output PCB’s
hexadecimal address.
Press the F1 Key to default the current
output parameters for all channels on the
displayed Current Output PCB to:
• Mode — 4-20 mA
• Calibration values —
20 mA value =14329 counts
4 mA value = 3738 counts
0 mA value = 1096 counts
The display flashes a message acknowledging
the entry. Pressing the F3 Key exits the
menu without defaulting.
If there are multiple Current Output PCBs, the
MVS advances to the address of the next
Current Output PCB.

No
This function allows manual activation of
current output channels outside of normal
control. The system issues a warning that
automatic control of current outputs assigned
to the selected channel is transferred to
manual control, and requests verification.
CAUTION
Manually activating current output can
cause damage if control equipment is
connected. Disconnect control equipment
before proceeding.
MVS Menu
After the warning message, if more than one
current output has been assigned for this
channel, a selection of the two current output
channels is offered. After you select a
channel, a Test display looks like this:
Iout01 :AD 15:Ch1
• Iout01 and Ch1 is the channel number on
the Current Output PCB. Each Current
Output PCB has eight multiplexed
current output channels.
• Ad 15 is the Current Output PCB’s
hexadecimal address.
• 04mA is the current sent to the current
output channel being tested. If the current
mode is 0-20mA, the test current output
ranges from 0 mA to 20 mA in 2 mA
steps. If in the 4-20mA mode, the test
current output ranges from 4 mA to
20 mA in 2 mA steps.
• More or Less refers to the increase
(More) or decrease (Less) of the output.
Press the F2 Key to increase output in
2 mA steps. Press the F3 Key to
decrease output in 2 mA steps.
Press the Esc or Auto/Man Key to terminate
the test. Once the test is terminated, the
current output returns to automatic control.
To test current output for another channel
assigned to this STX channel on the Current
Output PCB, select Test again and then
select the other current output channel.
STX Menu
After the warning message, a Test display
looks like this:
TEST 01 Addr 12
>04ma: More

F1 F2 F3
• 01 is the channel number in the MVS.
• Ad 12 is the STX PCB’s hexadecimal
address.
• 04mA is the current sent to the STX PCB
current output channel. If the current
mode is 0-20mA, the test current output
ranges from 0 mA to 20 mA in 2 mA
steps. If in the 4-20mA mode, the test
current output ranges from 4 mA to
20 mA in 2 mA steps.
• More or Less refers to the increase
(More) or decrease (Less) of the output.
Press the F2 Key to increase output in
2 mA steps. Press the F3 Key to
decrease output in 2 mA steps.
Press the Esc or Auto/Man Key to terminate
the test. Once the test is terminated, the
current output returns to automatic control.
