7. Auxiliary Equipment Inactive (cont.)
Test relay: high voltage (load side)
Step 7G
With the Auxiliary LED illuminated, test the load side of the relay off
the second terminal to ground (left to right) for 120VAC. For 240V
equipment, also test the fourth terminal to ground for 120VAC. IF no
voltage is present on either 2 OR 2 AND 4, then replace the relay
(GLX-RELAY). IF power is correct, the problem resides in the
equipment wiring or equipment itself.
