Shorted Transducer
PN957 (25-06-20)
Possible Causes
Shorted output
Damaged wire insulation
Missing Phase in 3-Phase motor
Entered wrong Service Factor Amps
Internal Pentair Pentek Intellidrive ®
Constant Pressure Pump Controller short
Power cycling on and off
High line voltage
Low line voltage
Temporary loss of power
Excessive load current
Loss of a motor phase
Power was removed from Intellidrive
Exceeding Service Factor Amps
No Service Factor Amps value entered
There is an open (connection) in motor wires
Locked rotor
Operation at open discharge
Intellidrive cannot read transducer signal
Possible leak
Dry running pump
Ground wire shorted to motor phase
Long motor cable length
Ungrounded Intellidrive
Unbalanced or three phase incoming voltage.
Possible Causes
Intermittent connection
Open Connection
Intellidrive cannot read transducer signal
Transducer wires crossed
Possible failed transducer
Short in transducer wires
Possible failed transducer
Solution
Check for any shorts in motor cables.
Check motor wire insulation with a megger.
Ohm cable and motor to confirm balanced Ohms.
Review motor perameters in main menu.
With power to Intellidrive off, measure outputs with ohmmeter to detect
short.
Check for a generator or switching on input line.
Measure incoming line voltage to Intellidrive; should be between 190V and
265V.
Check for local power outage.
Check motor is correctly sized for the application.
Check correct voltage is present on all motor leads.
Check correct voltage is present on all input lines.
Check Service Factor Amps entered are correct.
Check pump and motor are correct.
Check Service Factor Amps entered and are correct.
Check resistance of all motor wires is correct.
Pull pump check for debris in pump.
May need to reduce Dry Run Sensitivity pressure or apply back pressure
on transducer.
Check linearity of transducer, as it may be damaged.
Check for pipe break or large leak.
Check water level in well.
Check the ground wire for short to motor phase wire or check insulation
integrity with a megger.
Motor cable length more than 1000 ft is not recommended.
Ground Detect parameter can be disabled, but will reactivate after 72
hours.
Line to line voltage must be twice line to ground voltage.
Solution
Check all transducer wires are securely connected or for damaged cable
insulation.
Check for proper wiring of all transducer wires and verify cable connector
securely attached to transducer.
Check electrical system for ground loops or no ground connection.
Check red is in AI+ and black is in AI-.
Check linearity of transducer.
Check for shorted transducer wire or damaged insulation.
Check linearity of transducer.
