7.4.2 - COMMISSIONING THE REGULATOR WITH AUTOMATIC RESET
To commission the regulator (A) with automatic reset, proceed as indicated in Tab. 7.38.:
Step Action
1 Slowly open the shut-off valve upstream of the regulator (A) to feed it.
2 Unscrew the protection cap (B) of the reset knob (C).
3 Engage the knob (C) with the cap (B) through the special built-in hook.
4
Slowly pull the knob (C) with the cap (B) until the slam-shut device engages (the knob must not remain inside
the lid (D) of the slam-shut valve).
NOTE!
The greater the resistance encountered when pulling the knob (C), the higher the pressure up-
stream of the gearbox (A).
5 Release the reset knob (C).
6 Put the protection cap (B) back in place.
7
Wait for the lock-up device to automatically reset due to excess ow. The reset time is proportional to the
volume downstream of the gearbox.
NOTE!
Should the device not reset, make sure there are no leaks downstream of the regulator.
8
Once reset (Step 7), check that the slam-shut valve for maximum downstream pressure remains triggered.
NOTE!
The slam-shut valve for maximum downstream pressure is triggered if the knob (C) is visible in
the transparent area of the protection cap (B).
