3. Measure the proportional signal output voltage at channel A test point (TA) using the
multimeter as shown in the figure to the right and verify that it matches the table below.
Proportional Signal Output
No Trip Multiply +5.00 Vdc
2X Trip Multiply +2.50 Vdc
3X Trip Multiply +1.67 Vdc
3. If the voltage does not match the table above, adjust the gain potentiometer (GA) until
the voltage at the channel A test point is correct for the Trip Multiply option installed.
4. When finished, disconnect the function generator and multimeter and reconnect the
COM and IN wiring to the channel terminals on the Signal Input Relay Module that
was disconnected in step 1. Verify that the OK LED comes on and the OK Relay
energizes. Press the RESET switch on the System Monitor to reset the flashing OK
LED.
5. Repeat sections 17.1 and 17.2 for channel B substituting TB for TA and GB for GA.
• If the Channel Bypass or Danger Bypass functions were activated for this procedure,
deactivate them by setting the appropriate switches (BA, BB, or DB) to the right (OFF).
