Set Up for Construction Operation
3-5
• DNTD, UNTD: Up and down terminal limit switches. Connecting 2L bus to these termi-
nals clears the faults caused by the final limit terminals being open.
• USL1, USL2, DSL1, DSL2: Slow down limits. Connecting 2L bus to these terminals clears
the faults caused by having both sets of slow down terminals open.
• Custom Connections: Custom spare input connections that are active low and affect car
motion, such as the Pressure Switch and Low Oil Switch, must be installed.
Temporary Jumpers
Temporary jumpers, as necessary, may be connected if needed to run the car on construction /
inspection operation. For Temporary Run Box connections see page 3-6.
Resolving Faults
If the car does not respond to a run command, check the HC-MPU board for error/fault codes.
Please refer to “Status and Error Messages” on page 6-3. Error codes are displayed individually
in the order of detection. It is possible that, after you correct a current error condition, another
will be displayed. All errors must be resolved before the car will operate properly.
