Troubleshooting guide
Errors and Alarms
If an alarm is triggered the drive’s LCD screen will display the fault code text and the EnviroMAX 1500
Variable Speed 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.
–
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
therecould be excess voltage sag caused by improper installation or improper supply voltage.
–
Internal Errors:
These errors can occur based on operating conditions
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.

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.
–
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.

Internal Errors:
These errors can occur based on operating conditions
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.
