Hall Call Driver
Quick Test You can do a basic functionality test on the hall call driver.
With power applied:
1. Verify 120VAC power to the driver.
2. Unplug the Serial Bus connection (orange/blue wires).
3. Use a voltmeter to check the voltage between SHCS and SHCC. You should see approxi-
mately 30V, + or - 10%. (This voltage will only be present if the SC-HCE-ME or EM is
working properly as verified in preceding troubleshooting steps.)
If this voltage is present, the driver is probably operating properly.
