Circuit Breaker Function Pin No
CB1 MSM LINK Pin 22 to Pin 23
CB2 Warning Light Relay Terminal 11 and ground
CB3 MSM LINK Pin 10 to Pin 11
CB4 MSM LINK Terminal 1 to Terminal 2 Expected Result:Measure 24 V at the barrier outputs.Results:
YES - Measured 24 V at the barrier outputs. Proceed to Test Step 9.
NO - Did not measure 24 V at the barrier outputs.Repair: Replace the Barrier Control Panel.STOPTest Step 9. MEASURE INPUT VOLTAGE TO CIRCUIT BREAKER 7
Use a multimeter to measure voltage between circuit breaker 7 input and ground.Expected Result:Measure 24 V between circuit breaker 7 input and ground.Results:
YES - Measured 24 V between circuit breaker 7 input and ground. Proceed to Test Step 10.
NO - Did not measure 24 V between circuit breaker 7 input and ground.Repair: Replace the Barrier Control Panel.STOPTest Step 10. CHECK OUTPUT VOLTAGE FROM CIRCUIT BREAKER 7
Use a multimeter to check voltage between circuit breaker 7 output and ground.Expected Result:Measure 24 V between circuit breaker 7 output and ground.Results:
YES - Measured 24 V between circuit breaker 7 output and ground. Proceed to Test Step 11.
NO - Did not measure 24 V between circuit breaker 7 output and ground.Repair: Reset or replace circuit breaker 7. If the circuit breaker continually trips, replace the Barrier Control Panel.STOPTest Step 11. CHECK INPUT VOLTAGE AT MODULE INTERFACE

(6) Input module
(7) Output module
Check the voltage between "1L+" and "1M-" at BCP shutdown interface module (4).Expected Result:Measured 24 V between "1L+" and "1M-" at BCP shutdown interface module (4).Results:
YES - Measured 24 V between "1L+" and "1M-" at the BCP shutdown interface module. Proceed to Test Step 12.
NO - Did not measure 24 V between "1L+" and "1M-" at the BCP shutdown interface module.Repair: Replace the Barrier Control Panel.STOPTest Step 12. CHECK OUTPUT VOLTAGE AT BCP SHUTDOWN INTERFACE MODULE
Measure the voltage between "2L+" and "2M-" at BCP shutdown interface module (4).Expected Result:Measured 24 V between "2L+" and "2M-" at BCP shutdown interface module (4).Results:
YES - Measured 24 V between "2L+" and "2M-" at the BCP shutdown interface module. Proceed to Test Step 13.
NO - Did not measure 24 V between "2L+" and "2M-" at the BCP shutdown interface module.Repair: Replace BCP shutdown interface module (4).STOPTest Step 13. CHECK THE INPUT VOLTAGE AT MODULE POWER
Use a multimeter to measure voltage between pin 2 and pin 3 at power module (5).Expected Result:Measured 24 V between pin 2 and pin 3 at power module (5).Results:
YES - Measured 24 V between pin 2 and pin 3 at the
