f. Checking Output to Solenoids
This test checks the voltage that is used to
energize the solenoids.
1. Activate either BATTERY or AC120V oper-
ating mode.
NOTE
•The Brake Lock function is activated
by pressing any function button (except
BRAKE UNLOCK). A timer in the Relay
Box allows continuous output for about
7 seconds. If the brakes are already
locked, no output is provided.
•The BRAKE UNLOCK button activates
another timer in the relay box which
allows continuous output for the brake
release function for approximately 7
seconds. If the brakes are already
released (using the BRAKE UNLOCK
button) no output is provided.
2. Test connectors CN6 and CN7 from the back
while attached to the relay box. All connectors
should be connected.
3. Activate each of the pendant control buttons
and measure the output voltage for the corre-
sponding connector pins with a DC voltmeter. See
figure 6-20.

g. Test Results:
If you do not receive the correct meter readings, the
relay box is defective and should be replaced.
NOTE
•Before deciding the relay box is de-
fective, check the wires and pins in the
connector blocks to make sure they
are not loose or making a bad connec-
tion with their mate.
•If the battery power is ON and no table
functions have been activated for 3
hours, the power off circuit will interrupt
the battery power.
