Manual Emergency Operation On Built-In Lift Table Lt (Fig. 18) - Corghi ERCO X4300 Serie Betriebsanleitung

Manual emergency operation on built-in lift table lT (Fig. 18)

To lower the free-wheel lift table in the event of a power failure, proceed as follows:
1) turn off the master switch
2) open the control unit cabinet door
3) press and hold button A on pneumatic solenoid valve YV9 to raise the mechanical
safety devices. Check that both safety devices are raised before proceeding: if both
mechanical safety devices are not raised, operate the manual pump pM to raise the
built-in wheel lift table sufficiently to disengage both mechanical safety device claws.
4) unscrew cap B1 of the hydraulic solenoid valve YV5. Turn the adjuster screw B2 of the
solenoid valve anticlockwise
5) undo cap D of hydraulic solenoid valve YV7 or YV8, and press and hold button C on
solenoid valve YV7/YV8
IMpORTANT: make progressive adjustments using the two solenoid valves YV7 and YV8
in alternating order to prevent excessive misalignment between the two runways.
6) Once the built-in lift (LT) is in the completely closed position, release button A on the
pneumatic solenoid valve YV9, release the button C on the hydraulic solenoid valve
YV7/YV8, tighten the cap D, then turn the adjuster screw B2 on the hydraulic solenoid
valve YV5 fully clockwise and tighten the cap B1 covering the screw.
7) restore the normal operating conditions of the lift (close the control unit cabinet door
and arm the main switch).
