User Instructions ARG Series Standard Actuator - ACENIM0123-00 12/12

4.2.4 Bolt up the cylinder flange on the thrust base of the

Spring Module using the using the lock washers and

nuts from override mounting kit.

4.2.5 Thread in the hydraulic connector into the cylinder port

and connect it to the power pack, as per the schematic.

4.2.6 Fit the 3 way valves supplied in the mounting kit, to the

pressure module’s ports, as per the schematic.

4.2.7 Fill to level, hydraulic fluid (ISO 32 grade for general

application) in the power pack reservoir, in the full re-

tracted position of the piston.

4.2.8 Verify the maximum hydraulic pressure setting for the

actuator model (refer table), close the pressure release

valve on the pump and operate the hydraulic pump to

start the ram movement. Lightly loosen the air vent

screw on the cylinder flange to bleed off air from the

hydraulic lines. The ram touches the Pull Rod’s end

face and pushes the pull rod, effecting the override.

4.2.9 Adjust the overload valve setting on the pump to en-

sure the pressure does not grossly exceed the Hydrau-

lic pressure setting for the actuator, at the end of the

stroke when the stopper bolt gets loaded.

4.3 Operation –SR Override

4.3.1

To operate the override, turn the 3/2 way valve on pres-

sure module to vent the cylinder port to atmosphere and

Close the pressure release valve, PRV (provided either

externally or integral with the hand pump). Operating the

Hand Pump on the power pack pushes the pull rod, com-

presses the spring and operates the valve.

4.3.2

Opening the pressure release valve, PRV releases the hy-

draulic pressure and the spring returns the actuator to fail

safe state and the piston rod of override cylinder to retracted

position.

4.3.3 To restore normal Automatic operation, turn the PRV

to Open and switch the 3/2 way valve in position to

connect cylinder port to air supply pressure.

4.4 Install hydraulic override on Standard DA heavy

duty actuator

4.4.1 Remove the DA cover plate from the torque module

and mount the DA hydraulic override cylinder assem-

bly with the mounting kit and flange O-ring in the face

groove.
