PROBLEM
POSSIBLE CAUSE
SOLUTION
Cannot turn the manual override knob
Manual override selector lever in ‘AUTO’ mode
Move manual override selector to ‘MAN’ mode
Excessive force applied to manual override
knob, this may have damaged the gear drive
If after selecting ’MAN’, manual override still does
not work, replace with a new actuator
Valve jam
Clear valve jam and try again
Actuator fails to operate and
condensation or water is found inside
the actuator
DIN plug connectors are loose, missing or have
damaged seals. Connector seal installed
incorrectly.
Inspect seals and replace if necessary. Make sure
seals are installed correctly and tighten DIN
connectors screw securely (0.4 to 0.5Nm).
Built in heater was not activated continuously
Power must be maintained to the actuator either
in the open or closed position to activate internal
heater. This heater will help prevent condensa-
tion buildup inside the actuator. If the actuator
has failed due to excessive condensation or water
inside the actuator, replace with a new actuator.
Actuator fails and excessive black dust
and/or corrosion is found under the
red cover
Excessive condensation or water inside
actuator. Highly corrosive environment,
saltwater, chemicals, other.
If the actuator has failed due to excessive black
dust or corrosion inside the actuator, typically it is
non-repairable and must be replaced with a new
actuator.
Black dust from motor brush wear may be
caused by exceeding the 75% duty rating of the
actuator.
Actuator must be operated within the 75% duty
cycle rating. Typically, this means the motor can
be running for 45 seconds, then must be off for
15 seconds of each minute.
Actuator is worn out
Replace with a new actuator
Switches are wired incorrectly
Check the switch wiring and make sure the
common for limit switches is on PIN 1. If checking
continuity, you should have continuity between
PIN 1 and 2 when actuator is closed and
continuity between PIN 1 and 3 when open. No
continuity when actuator is moving in between
closed and open positions.
No output signal from position
confirmation limit switches
Exceeding the current capacity has damaged
the limit switch. Switch rating 3 amps @
125/250VAC, 30VDC resistive load.
Damage to the limit switches is not a field
repairable item. Either return actuator to the
factory for possible repairs or replace with a new
actuator.
Limit switch cams are out of adjustment.
Limit switch cams can be adjusted if necessary.
