CAUSE C (Unlikely)
All the lights are faulty.
SOLUTION C
Replace all the lights, they are connected to L1600 (Z-
motor driver) and then realign them. Refer to the instal-
lation manual.
Up/down (Z-motor) keys do not work
CAUSE A
The emergency switch has been pressed down.
Image of emergency button appears on main display.
NOTE: LED D4 (ESTOP on) on L1600 will come on
when the emergency switch is pressed down.
SOLUTION A
Turn the emergency switch clockwise to release it.
CAUSE B
Z-motor not receiving power.
SOLUTION B
Check to see if lamp LA1 and LED D1 on L1600 are on.
If they are not then check fuses F1 and F2. Replace if
blown.
If after replacing fuse F2 lamp LA1 comes on but LED
D1 still does not come on,check cables between L1600
and L1700. If the cables are OK, check if D12 is on on
L1500. If it's not, replace L1500.
If LA1 and D1 are on check the cable from L1600
(J104) to the Z-motor. Replace if faulty.
If the cable is not faulty measure the AC voltage from
the Z-motor connector, on L1600, to the Z-motor. Press
the UP/DOWN key and check that there is an AC-volt-
age.
Note that you need to connect the DMM differently
when running the unit in the Up direction and in the
Down direction.
If no voltage can be measured, replace L1600.
If there is voltage but the Z-motor does not operate,
replace the Z-motor.
Check the autotransformer connection.
Make sure that only one of the primary windings is con-
nected.
D5 = SET 100V
D6 = SET 115V
D7 = SET 230V
