SAFETY PRESSURE SWITCH
(WITH AUTO RESET FUNCTION)
The RG3000-E is equipped with an internal Automatic Safety Pressure Switch. If the
pressure inside the system exceeds 38,5 bar, the system is switched off automatically.
If the Safety Pressure Switch is activated automatically while filling a bottle, it could be
caused by the bottle becoming overfilled.
This is a very dangerous situation! You should take steps immediately to reduce the
overpressure and/or to eliminate the overfilling of the bottle.
If the Safety Pressure Switch switches the unit off...
The following precautions should be taken if the Safety Pressure Switch is activated:
a) Suspected overfilling of the recovery bottle
Connect the recovery bottle to another bottle with spare capacity so that the pressure
is reduced to a safe level. This action should also reduce the pressure in the outlet line
from the RG3000-E.
b) Cause of activation of Safety Pressure Switch unknown
1) Check that the recovery bottle is not overfilled.
2) Close the system valves, recovery bottle valves and RG3000-E valves.
3) Disconnect RG3000-E from flexible hoses.
4) Disconnect RG3000-E from the power supply.
5) Open the inlet and outlet valves very slowly.
6) Investigate the reason for the failure.
Once activated, the Automatic Safety Pressure Switch will reset itself if the pressure is
reduced below 38 bar.
