Check for Shorts to Ground
With no power applied to the controller:
1. Note, then unplug the five input-end connectors from the SCE-UPD board. See illustra-
tion below.
2. Remove touch-safe fuse covers. Measure resistance from each fuse (either end) on the
board to ground.
3. If there are any shorts to ground, troubleshoot related connections to find and correct
the short.
4. Replace touch-safe fuse covers.
5. Reconnect the input connectors to the SCE-UPD board.
AC Power, Motor, Brake
Connect AC power, motor, and brake as shown in the job prints.
Wire Separation
High voltage wiring must be routed in separate conduit from control or digital communications
wiring to avoid potential interference. Size the conduit so that removing pre assembled connec-
tors is not required.
Initial Power Check
Always have a helper standing by the AC disconnect to power up the controller and to immedi-
ately shut down if necessary.
1. Verify that the Machine Room Inspection switch is in the INSP position.
2. Check the line side of the Main Power Disconnect switch to verify that all three legs are
at the correct voltage.
3. Physically verify that all car and hoistway doors are closed and locked and that no one is
in a dangerous position should the car move unexpectedly.
4. Power up the control. Be prepared to immediately shut it down if the car attempts to
move.
