Troubleshooting - Hayward ECP3 Series Installation, Operation And Maintenance Instructions

TROUBLESHOOTING

After completing all mounting and wiring procedures and main power is available, if the actuator does NOT respond as
expected, the following procedure(s) may help in identifying the problem. If using this troubleshooting guide does not
resolve your issue please contact Hayward Flow Control Technical Services at 888-429-4635.
Symptom
Actuator does
not move when
commanded
to do so .
Supply and controls
are measured to
be correct, but
actuator still does
not move .
Actuator does not
stop at correct
position at either
end of travel
Motor is extremely
hot to the touch .
Target
Power Source Measure incoming power AT the actuator Power Supply Plug.
Generate move commands by the field device. Measure correct
Control Problem voltage changes between terminals 1 and 3 (CCW) and between
terminals 1 and 2 (CW) on the Power Supply Plug.
Declutch Lever
Reset Declutch Lever to Automatic.
set to (B) MAN
Wire Sizing Check for correct wire size per Wire Sizing Chart.
Improper Wiring Check wiring per wiring diagram
Remove the actuator from the driven device. If the actuator now
moves, the torque required by the mechanical device exceeds
that of the actuator. Increase actuator size.
Overtorque
With the actuator removed from the mechanical equipment,
manually rotate the valve or damper through its intended range
of travel to check for mechanical problems or an obstruction.
DIP Switch Settings Check to be sure the DIP Switch Settings match the incoming
(Proportional Only) control signal
Insufficient power
Measure the voltage between terminals 1 & 2 WHILE
supply and/or
commanding the actuator to move. The measured voltage
incorrect wire size
cannot drop more than 10%.
during installation.
Cams improperly Remove Power. Cams MUST be secure and set according to
the procedures in the Adjusting CW/CCW End of Travel section.

The manual override system has been employed to rotate the actuator
Actuator is out of
beyond its intended angle of rotation. Use the manual override to
quadrant
rotate the actuator back into its correct quadrant of operation.
Travel cams not Reset end-of-travel cams as detailed in the Adjusting CW/CCW

Check for stray voltage fluctuations on the incoming control
Control "noise" or
signals. The on/off actuators have a maximum 75% duty cycle.

Check the site as-built wiring diagrams to verify.
Remove the actuator from the driven device. If the actuator now
moves, the torque required by the mechanical device exceeds
that of the actuator. Increase actuator size.
