Variable Speed Pump Installation and User' s Guide
Corrective Action
Check voltage at motor terminals and at panel while pump
is running. If low, see wiring instructions or consult power
company.
Check for loose connections.
Check line voltage; if less than 90% or more than 110% of
rated voltage consult a licensed electrician.
Increase ventilation.
Reduce ambient temperature.
Tighten any loose wiring connections.
Motor runs too hot. Turn power to motor off.
Check for proper voltage.
Check for proper impeller or impeller rubbing.
Check the connection between the drive and keypad. See
image on page 3. The drive wiring connection should be
tight.
If suction and discharge piping are not adequately
supported, pump assembly will be strained. Do not
mount pump on a wooden platform! Securely mount on
concrete platform for quietest performance.
Disassemble pump, clean impeller, follow pump service
instructions for reassembly.
Improve suction conditions.
Increase pipe size.
Decrease number of fittings.
Increase discharge pressure.
Inspect motor slinger and motor shaft seal behind the
slinger (NOT the pump's mechanical seal). Apply lubrication
to the motor shaft rubber seals.
1. Be sure that the communication cable is
connected at both ends.
2. Check that the pump local address matches with the
address used in the IntelliTouch control system.
3. Check that the pump has been assigned a circuit name
on the IntelliTouch control system.
4. Ensure that the pump display says
"DISPLAY NOT ACTIVE".
A defective device on the network can inhibit the proper
operation of other network device. Devices
should be disconnected sequentially until the
network starts working.
