flashes Controller Status Description
6 Blinks Ground Fault This device does not provide personnel protection against shock.
This function is intended for equipment protection only.
This fault can be caused by:
• Electrical failure of the motor
• Electrical failure of wiring between controller and motor.
• Miswiring of motor cable.
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 and wait 1 minute. Remove the three motor wires and ground wire
from the terminal block. Check wiring and motor for shorting phase to ground
using a megohmmeter (“megger”). A reading less than 200K Ohms indicates faulty
insulation in the motor cable or motor. Test each to determine fault location.
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 14ºF
(-10ºC).
Check for a fan failure. The fan will turn on when the temperature inside the
controller reaches 140ºF (60ºC). The fan will turn on for 1 second each time the
controller starts the motor. If the fan never turns on, check fan connections and
replace as needed. Ensure that the external fan intake filter is not blocked or
clogged. It can be removed for cleaning and replacements are available.
8 Blinks Open Lead This fault can be caused by:
• Disconnected or broken wire between the controller and motor.
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.
Using an ohmmeter, measure the resistance from phase to phase. A disconnected
or broken wire will be indicated by a high resistance reading (20 ohms or higher).
9 Blinks Low Pressure Cut-Off This fault can be caused by:
• Pressure 20 PSI below set point for 30 seconds. May be a broken pipe or tripped
pressure relief valve. If 20 PSI or more pressure drop for 30 seconds is normal for
the system, switch the broken pipe protection off or change system to prevent
the pressure drop.
