Sensor Fault
(continued)
Where:
• Output Current is the transducer output
• Output Current Range is the maximum output signal of the transducer
minus the minimum output signal of the transducer.
In this case:
Output Current Range = 20mA – 4mA, or 16mA
• Pressure Range is the pressure that corresponds to the maximum out-
put signal. For a 300 PSI transducer the Pressure Range =
300 PSI – 0 PSI = 300 PSI
• System Pressure is the system pressure as read on the pressure gauge.
4 Blinks
Pump or Motor Bound
This fault can be caused by:
• Mechanical binding from debris in pump.
• Electrical failure of the motor.
• Incorrect setting of Motor Overload Setting switches.
• Incorrect rotation.
• Motor phase loss.
This fault will be displayed if the output current exceeds 125% of the
controller rating. The controller will attempt to restart 5 times. If the condi-
tion persists the controller will lock out and will need to be reset. Verify the
error by turning power to controller off for 5 minutes and then on. Pump/
Motor/Wiring must be checked if fault persists.
5 Blinks
Short Circuit/Ground Fault
This fault can be caused by:
• Electrical failure of the motor
• Electrical failure of wiring between controller and motor.
This fault will be displayed if the output current exceeds 150% of the
controller rating. Verify the error by turning power to controller off for 1
minute and then on. If error persists, motor and wiring between controller
and motor must be checked. Turn power off for 5 minutes. Remove the
three motor wires from the terminal block. Check output wiring and motor
for shorting phase to phase and phase to ground. Refer to motor's manual
for information on resistance readings and megger readings.
6 Blinks
Input Phase Loss
This fault can be caused by:
• Disconnected input power phase.
• Incorrect Motor Overload Setting switches. When using single phase
input power the Motor Overload Setting switches must be set to 50% or
lower.
For three phase input operation; this fault will be displayed if input volt-
age imbalance is more than 3%. The controller will attempt to restart 5
times. If the condition persists the controller will lock out and will need to
be reset.
7 Blinks
Temperature
This fault can be caused by:
• High ambient temperature. The maximum ambient temperature rating
is 122ºF (50ºC).
• Low ambient temperature. The minimum ambient temperature rating is
-22ºF (-30ºC).
This fault will be displayed if the ambient temperature is greater than
122ºF (50ºC) or less than -22ºF (-30ºC). Do not install the controller where
it will be exposed to direct sunlight. Check for a fan failure. The fans on the
back of the controller will turn on only when needed. The fans will turn on
when the motor is running and the heatsink temperature reaches 104ºF
(40ºC).
