THREE ACTUATOR SYSTEM
The following initialization procedure applies to a three actuator system and requires two people to complete it:
1.
With the bonnet in the down position and the actuators properly connected mechanically and electrically,
raise the heat zone no more than 1” (25mm).
2.
Disconnect the power to the control box by shutting off the F52 circuit breaker for at least 5 seconds
3.
On the operator control panel, turn the hood selector switch to the UP position while reconnecting the main
power to the actuator control box. Listen for the buzzing sound coming from the control box. At this point
turn the hood selector switch to the DOWN position; this will activate all three actuators to the DOWN
position.
4.
Keep the hood selector switch engaged making sure that each actuator pulls the main heat zone down
tightly against the lower channel, then release the hood selector switch.
5.
Disconnect the power to the control box again by shutting off the F52 circuit breaker for at least 5 seconds.
The initialization process is now complete.
Periodic Inspection and Maintenance:
Clean the piston rod in the fully extended position and inspect for mechanical wear or damage. Inspect the
attachment points, wiring, plugs, and control box. The LINAK actuator is an enclosed unit and does not require any
internal maintenance or lubrication.
Troubleshooting:
------------------------------------------------------------------------------------------------------------------
Symptom:
No motor sound or movement of piston rod.
Possible Cause:
1. The actuator is not plugged securely into the control box.
2. Blown fuse in the control box.
3. Cable damage.

Symptom:
Movement of actuators not synchronized.
Possible Cause:
