Install the adapter as indicated opposite to fit
the two polarising studs (4) side by side, then
install solenoid valve 302.
The mounting direction as shown in the
drawings below must be observed when installing
the pilot valve 189 00 007 (without manual
override) onto these products.

❉ Important: if a pilot is to be installed on the
solenoid/air controlled soft-start
device, the pin (6) must first be
removed (see Fig. 1 overleaf)

ADJUSTMENT OF DOWNSTREAM PRESSURE BUILD-UP TIME
GB GB
In both soft-start device versions, the filling rate, i.e. the pressure build-up in the downstream circuit, is adjusted by means of a
fine-thread screw. Components are supplied with the screw fully in (closed position, zero flow).
Adjustment is as follows:
- Unscrew the screw by 0.5 to 6 turns to obtain the desired filling speed (Fig. 2).
- Perform a test.
- Regulate the setting by adjusting the screw. Before retesting, vent the installation with the shut-off valve.
- When the correct setting is obtained, insert the pin to lock the screw and prevent unauthorised adjustment of regulated
pressure (see Fig. 3). To change the adjustment, it is necessary to remove the upper cover and withdraw the pin (Modulair 112).
Note: With a solenoid/air controlled soft-start device, the adjustment must be made with the electrical pilot installed (see Fig. 2).
To fit the locking pin, it is necessary to vent the installation and remove then reinstall the pilot (see Fig. 3 and 4).
