356282 | Pentair SuperFlo VS / VST WhisperFlo VS / VST Motor Drive Kit

21 – Communication Link between the HMI and Motor Control has been lost: Remove the top cover from the drive and inspect the jacketed wire on the backside of the keypad. Ensure that the 5-pin connector is properly plugged into the socket and that there is no damage to the cable.
02 – Power Module Over Current Detected: If this error displays multiple times, then there may be a problem with the pump’s rotating assembly. Disassemble the pump (see Pump Disassembly on page 16) and inspect the impeller and shaft seal for problems.
0F – Absolute AC Under Voltage Detected: 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 drops caused by improper installation or improper supply voltage.
19 – Motor Start Failure: Could indicate a locked rotor. Verify the fan at the rear of the motor is free of debris. Attempt to break up impeller blockages by rotating the motor shaft through the fan cover using a hex-key. If this does not work the pump may need to be disassembled (see Pump Disassembly on page 16).
0b – AC Voltage Maximum Exceeded: Indicates that the supply voltage is exceeding the operating range of 251v.
1A,17,16, 02, 08, 04, 06, 09, 0A – Internal Errors: These errors can occur based on operating conditions and the required self-diagnostic safety software. If they do not clear after multiple restart attempts the drive should undergo a hard power cycle. Disconnect power at the circuit breaker long enough for the keypad LEDs to turn off. If the error continues to appear after power is reconnected, the drive may need service
