Faults Description
Suggestion(s)
oL1/
oL2
Motor/Drive
Overload
Leave power to drive off for three minutes. Check to make
sure the motor coupling spins freely by hand.
System may not be balanced for flow.
Exceeding the flow rate of the pump design.
Supply voltage too low.
oC Over
Current
Meg the motor to determine the insulation resistance is
within specification (refer to back of manual).
Inspect the motor leads and terminal wires for exposed
shorts or grounds.
Leave power to drive off for three minutes. Check to make
sure the motor coupling spins freely by hand.
Maximum PSI Ratings:
CR32-1-1 = 30 PSI
CR32-1 = 35 PSI
CR45-1-1 = 39 PSI

Feedback
Loss
Make sure the wiring for the transducer is correct. Check
for loose wires on the connection of the transducer “+V”
and “A2”.
+V = Brown
A2 = Black
Check water level in canister.—Must have a minimum of
three feet of water above inlet.
OH
Heatsink Over
Temperature
Make sure the fan is in operation when the drive is
operating.
Uu Under
Voltage
Make sure voltage supply (1x230) to the V1000 is
between 200 and 240 volts.
Reason(s)
Motor/Drive current has
exceeded service factor
amps.
Motor insulation damage.
One of the motor cables
has shorted.
Load too heavy.
Pressure set too high.
Transducer out of range.
Temperature limit of the
drive is exceeded.
Main out of range.
oU
Over Voltage Main out of range.
Make sure voltage supply (1x230) to the V1000 is
between 200 and 240 volts.
LF
Phase Loss on
Output Side
of Drive
Wiring issue.
Make sure all leads to motor are connected to the drive
and are solid connections. Motor may be incorrectly wired
for 3x460V, the motor MUST be wired for 3x230V.
Wire connections in motor terminal box may be loose,
double check connections.
