If the red LED is lit on the motor controller, there is an error that prevents the motor from running.
1. Check Input Voltage
Must be within +/- 10% of the motor voltage rating.
When the motor controller was originally commissioned, the installer had to select the motor input voltage.
- Using the Turntide Technician App, verify the motor input voltage was set correctly. From the motor summary screen, tap Settings, then General.
- In the General Settings screen, make sure the displayed Input Voltage matches the voltage noted on the nameplate of the Turntide motor.
- Note: 208VAC units have their own voltage setting and will not
operate using the 230-240 setting.
- Note: 208VAC units have their own voltage setting and will not
- If the input voltage setting was correct, check the incoming power to ensure all 3 phases are within +/- 10% of motor voltage rating.
2. Motor Torque
- A low torque alarm indicates that belt is extremely loose or broken OR the motor is turning in the wrong direction.
- A high torque alarm indicates the motor has much higher resistance than expected. This could be caused by a mechanical issue with the blower assembly or with the motor itself. Verify for proper belt tension and verify the blower fan assembly and motor spin freely.
3. Restart Attempts
When a critical alarm occurs, the motor controller will attempt to restart the motor twice by default. If this operation setting was set to 0 in the Turntide Technician App, then any alarm condition would render the motor inoperable until the power is cycled OR the alarm is cleared using the Turntide Technician App.
To ensure that the motor Restart Attempts option is set to a default of 2:
- Using the Turntide Technician App, from the motor summary screen, tap Settings, and then tap Operation.
- In the Operation Settings screen, tap Restart Attempts. Enter 2 and tap Done.
