TROUBLESHOOTING
Fault Possible Causes Solution
Over Temperature
Excessive heating in
Pentair Pentek
Intellidrive
®
Constant Pressure Pump
Controller
Check ambient temperature is not above 50°C (122°F).
Check for inoperable or unobstructed fan.
Check vents are not obstructed.
Excessive Runtime
Leak detected Check for leaks in pipe system.
Application calls for long run times
Extend Excessive Runtime Hours limitation.
Disable Excessive Runtime Fault.
Internal Fault Internal voltages are out of range
Intellidrive will auto reset and attempt to clear fault. Fault Reset can be
pressed to clear fault as well. Then try to operate pump. If fault continues
Intellidrive may need replacement.
Hardware Fault Internal hardware failure
Fault Reset can be pressed to clear fault. Then try to operate pump. If
fault continues Intellidrive may need replacement.
External Fault
The external device detected fault condition
and closed the I1 or I2 input
Check external device.
Low Amps
Motor not wired correctly to Intellidrive 2-Wire motor should be connected to Y & B
Thermal protector open in 1-phase motor Wait 20 minutes then restart pump.
Missing motor phase Check all motor connections at the Intellidrive.
Warning Possible Causes Solution
Warning LED flashing
Ungrounded Intellidrive, with ground detection
parameter disabled (will operate for 72 hours
and then fault).
Verify ground wire is connected on both incoming voltage side and motor
side of Intellidrive.
With the power disconnected, use an ohmmeter to verify which pipe the
Intellidrive’s transducer is connected to. Also verify that the input ground
wire is at the same potential, e.g., has approximately the same ohm
reading.
Verify the input ground is connected all the way back to electrical panel.
Jam Warning
Debris in pump stopping motor from turning
(locked rotor).
Intellidrive tries to free debris in pump by reversing or pulsing motor.
Over Pressure Warning Pressure rising above Over Pressure setting.
Intellidrive stops and waits 1 minute, then checks that pressure is below
the Overpressure Setting pressure. Below it restarts, if not checks again in
another minute. Can increase over-pressure value.
Plugged vents, fan not working, high ambient
temp, direct sunlight, etc. Also high power
draw.
Improve ventilation, verify fan is working, provide shade, etc. Verify proper
system sizing.
Hardware Fault Internal Intellidrive error. Power cycle the Intellidrive. If Fault continues Intellidrive may need
replacement.
Parameter Out of Range Internal Intellidrive error. Power cycle the Intellidrive. Reset Intellidrive to factory defaults. If Fault
continues, Intellidrive may need replacement
Temp Meas Error Internal Intellidrive error. Power cycle the Intellidrive.
DC Undervoltage Low voltage on DC Bus caused by heavy
loading, low incoming voltage, or unbalanced
output current.
Check wiring for shorts, imbalance, and voltage. Verify proper grounding.
