5 - Check alarm relay outputs.
NOTE: Model 10C control cards are 2 alarm devices. Disregard the alarm 3 (D8) LED on
the test fixture for this test.
FLT, ALM1, and ALM2 LEDs (D5, D6, & D7) will be dimly illuminated when not in
alarm. This dim illumination indicates that the normally closed contacts are operating
properly.
Turn SW1 clockwise until ALM1 and ALM2 LEDs on the Model 10C illuminate. Verify
that the corresponding alarm LEDs on the test fixture (D6 and D7) also illuminate.
Return SW1 to the “4mA” position.
If alarms on the control card are programmed for latching, push the RESET button to
deactivate. Test the Remote Reset button on the test fixture by reactivating the (latched)
alarms and then use SW2 to reset. The control card display will indicate “EXT ALM
RST”.
Turn SW1 to the 0 mA position and verify fault LEDs illuminate on the control card as
well as the test fixture (D5).
6 - Open Collector LEDs. The open collector LEDs (D9, D10, and D11) should
illuminate with the corresponding alarm LED located under them. The open collectors do
not have a dim state when alarms are off.
4.3 Model 12, 12A and 12B Control Cards
NOTE: These instructions are based on the assumption that the Model 12 control card has
already been calibrated and basic alarm options have been configured.
1 - Turn the power switch on. Note that the digital mA Output LED meter illuminates
with a reading of 00.0.
2 - Plug the Model 12 control card into J2.
3 - Note that the Sensor Power LED (D4) is illuminated. This indicates power from the
control card to the sensor.
4 - Verify mA input and output using the mA input range selector switch (SW1).
SW1 Position Mod 10 mA Output Display (±0.1)
0mA 000 03.6
2mA 000 03.6
4mA 000 04.0
12mA 50 (±1) 12.0
