Errors and Alarms

If an alarm is triggered the drive's LCD screen will display the fault code text and the SuperMax
Pump will stop running. Disconnect power to the pump and wait until the keypad LEDs have all turned off. At this point,
reconnect power to the pump. If the error has not cleared then proper troubleshooting will be required. Use the error
description table below to begin troubleshooting.

– Communication Link between the HMI and Motor control has been lost: Check the jacketed wire on the
back side of the keypad inside the drive top cover. Ensure that the 5 pin connector is properly plugged into the socket
and that there is no damage to the cable.

– Power Module over current detected: If this error displays multiple times, then there may be a problem with
the pump's rotating assembly. Please disassemble the pump and investigate to see if there is a problem with the
impeller or mechanical seal. See page 14 "Pump Disassembly" for instructions for disassembling the pump.
0F
– Absolute AC Under Voltage Detected: This indicates that the supply voltage has dropped below the operating
range of 99v. This could be caused by normal voltage variation and will clear itself. Otherwise there could be excess
voltage sag caused by improper installation or improper supply voltage.

and the UL 60730 required self-diagnostic safety software. If they do not clear after multiple restart attempts the drive
should undergo a hard power cycle. Disconnect main power by turning off the breaker long enough for the keypad
LEDs to turn off. After power is reconnected if one of these errors continues to reappear, the drive may need service.
