7.4 Throttle module: adjusting the throttle
NOTICE
Danger of overturning the adjustment screw!
Damage to the throttle module!
u Never turn the adjustment screw firmly all the way to the stop (maximum
tightening torque: 0.5Nm).
Throttle modules come in uni-directional and bi-directional versions. You can
identify the version by the symbol (23) on the front.
Operating lines2 and 4 can be reduced independent of each other.
To set the flow in the operating line you must set the adjustment screws for con-
nections2 or 4.

1. Use a 5mm Allen key to turn the adjustment screw (21, 22) counterclockwise
to increase the flow.
The setting in the end stop corresponds to the maximum possible flow.
Turn the adjustment screw clockwise to reduce the flow.-
2. If necessary, secure the adjustment screw with a cover plate (24) and/or a
cover sticker (26).
