7.
Put the gearbox into the fully closed position by turning the handwheel clockwise.
8.
The actuator must also return (the valve) to its fully closed position. When the fully closed position can
not be achieved, loosen the stopscrew-close of the gearbox (see figure 4) and check the travel stop
adjustment of the actuator.
9.
Turn the stop-screw back into the gearbox until blocked (handtight). Secure the stopscrew–open with
the counternut.
10.
If still no return to closed position is achieved, check if any obstacles prevent the valve from returning
back into its closed position.
11.
Be sure the gearbox and valve are in fully closed position.
12.
Adjustment completed. The assembly is ready for automatic operation

Operating
Under normal circumstances the valve is operated by an automatic actuator. The ILG/S gearbox allows manual
operation (closing or opening) of the valve in case of malfunction in the automatic actuator-system.
1.
The gearbox is operated by handwheel.
2.
The valve is closed by turning the handwheel clockwise.
3.
Stop turning when the required valveposition is achieved. The number of rotations of the handwheel
needed to turn the valve from fully opened to fully closed position is listed in table 2.
4.
When the valve can not be totally closed, first detect and solve the cause of failure.
5.
In case of malfunction of the gearbox, this has to be replaced (see chapter 2 for dismounting). Return
the gearbox to your supplier for repair.
6.
When you do the repair in house, all replacement parts must be obtained from the manufacturer to
assure proper operation of the gearbox.
7.
The gearbox is self-braking. Therefore no fixation is needed to retain the valveposition

.
8.
When the cause of the malfunction is solved, turn the handwheel until blocked (for correct stand of the
gearbox, see chapter 2: installation).
9.
The system is ready for use.

Option is a fixation of the the inputshaft to prevent (not allowed) turning.
