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

 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.

 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.

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.
