Manual Override Operation
Remove manual override hex key from storage position located on the bottom of
actuator, which is secured by stainless steel clips. To operate the manual override,
insert hex key into hex socket located on top of actuator and rotate to manually cycle
valve (CCW to open, CW to close). When finished using the manual override, it is
imperative to remove the hex key and place it back into storage on actuator base,
making sure that it “clicks” into the locking position.
CAUTION: The manual override should only be used when there is no power applied to
actuator. When power is restored, the actuator will automatically resume normal
operation.
Local Controls Operation
The actuator can be locally controlled and driven to the open or closed position via
OLED screen and push buttons. This simple procedure is detailed below.
Press and hold the “↕” button for 3 seconds. “K3” will flash in the top right hand corner
and the unit will ask for a password. At this time, the password of “111” can be entered
with “↕” selecting numbers and “↔” selecting the field. Once password is entered, press
the “M” button to enter manual mode. The actuator can now be opened and closed via
the push buttons. Press the “↨” button to OPEN the actuator. Press the “↔” button to
CLOSE the actuator. To exit manual mode, press the M button or wait approximately
120 seconds and the manual mode will time out and exit. The actuator will not respond
to control signals from the PLC until taken out of manual mode.
