Troubleshooting
Symptom Potential Cause(s) Recommendation(s)
Electric drive does
not cycle when
powered
Pump controller is o Press the On/O button to cycle power
Loose or damaged power supply wiring Conrm all connections are securely fastened and that no mechanical
damage to wiring has occurred
Re-connect wiring and thread together tightly
Wiring polarity reversed on main power
supply cable
[see 'instAllAtion' section of this MAnuAl for
wiring diAgrAM]
Reverse wiring if found to be incorrect.
[Warning: Control module boards manufactured prior to 2010 may not
be equipped with reverse polarity protection and if powered in a reverse
condition will require replacement]
Damaged fuse Remove fuse holder cap and inspect fuse for damage. Replace if required
[0.25 x 1.25” - 2.5A]
Low voltage condition *
*if your systeM is equipped with the integrAted
low voltAge disconnect [lvd] the screen will
displAy 'pp' indicAting A power probleM [low
voltAge condition]
Conrm 24V DC power supply is available to the control module with a
volt meter. Replace or repair power supply as required
If the System is running o a DC battery bank it is recommended to disconnect the charging source [i.e. solAr pAnels] before checking line voltage
to ensure accurate results
Damaged charge regulator Conrm charge regulator is outputting 24-28V. If your charge regulator
is equipped with a low voltage disconnect make sure to test its functionality and set points
Controller display
does not respond to
pressing on/o or
stroke rate buttons,
but the drive is
cycling normally
Pump is in analog mode [4-20 mA input] If your pump is equipped with the optional 4-20 mA analog input it will
override manual entries when in remote mode. Disconnecting the 4-20
mA input cable will resume normal manual operation
Pump is chattering
or not stroking the
full stroke [1 inch]
note: during norMAl
wArM up routine cycles
['up' shown on displAy]
the puMp will cycle
hAlf strokes And does
not indicAte A probleM
with the drive
Low voltage condition Conrm 24V power supply is available to the control module with a volt
meter
If the System is running o a DC battery bank it is recommended to dis-
connect the charging source [i.e. solAr pAnels] before checking line voltage
to ensure accurate results
This condition can cause damage to the Systems drive if left for extended periods. If after identifying and correcting a voltage problem and the drive is still found to chatter it is recommended to send
the System in for inspection as motor bearings may be damaged
Discharge Isolation valve(s) closed If any valves are found to be closed and if safe to do so, open valves
Original controller replaced MCI oers many drive options that require specic controllers. Before
installing a new pump controller please contact MCI customer service:
+1.250.888.4565 to conrm compatibility. Please provide the Systems
model and serial number to conrm compatibility
Pumps maximum rated discharge pressure has been exceeded
Please conrm your pumps maximum output pressure rating. This can
be found under the 'Specications' section of this manual. It is very important this pressure not be exceeded. It is unsafe and will cause premature System failure.
