from the Run Box. Verify that the car runs with no faults for 10 seconds or more. See No

The following sections list troubleshooting procedures.
Soft Starter Fault
If the Smartrise controller indicates a soft starter fault and the soft starter has the fault LED
flashing, see Appendix 1 Sprecher + Schuh Troubleshooting Chart.
Wrong Direction
If the motor is running in the wrong direction, swap any two motor leads.
Car Not Moving or Too Slow
If the car is not moving or to slow perform the following:
• If the car does not move, verify that the valve relays are turning on when a direction is
given (for example, UPL and SM for the Up direction and DNL for the Down direction.
• Measure the outputs to verify that the Valve board is working properly. If the proper
voltages are present, check the wiring and the valves.
• Adjust the valves as required to get proper starts, stops, and run speeds.
• Verify the valve status by navigating to STATUS | VALVE 1 STATUS.
No Control
If there is no control perform the following:
• Verify the SFM and SFP relay are high when commanding the car to move.
• Verify the fault contactor is engaging when the car is commanded in either direction but
the pump motor only comes on in the Up direction.
• Verify 120 VAC is present when the car is being commanded to run on the MR board for:
