Tab. 8.43.
8.2.1 - FUNCTIONAL CHECKS OF SAFETY DEVICES
To check the safety devices for proper operation, it is necessary:
• that the system has a shut-off valve downstream of the regulator;
• that the system is set up with a pressure outlet downstream of the regulator or that the regulator is equipped with a
built-in pressure outlet (see paragraph 4.6.4);
• that an external pressure source with pressure control is available;
• that the external pressure source is connected to a pressure gauge and to a tap with a 4 mm maximum ow section.
NOTE!
Gas dispersions in the environment must be reduced to the bare minimum.
To check the safety devices, proceed as described in Tab. 8.44.:
Step Action
1 Close the valve downstream of the regulator.
2
Prepare the external pressure source with a pressure gauge to monitor the pressure.
NOTE!
The maximum pressure introduced downstream of the regulator must not exceed:
• 300 mbar for the BP version;
• 1 bar for the TR version.
3
Connect the external pressure source to the pressure outlet downstream of the system or, if any, to the pres-
sure outlet on the regulator.
NOTE!
To use the pressure outlet on the regulator, see paragraph 4.6.4.
4a
Pds (adjusted pressure) check:
1. open the tap of the external pressure source;
2. check that the pds value is ± 10% with respect to the value indicated on the nameplate applied.
4b
Internal sealing check:
1. close the tap of the external pressure source;
2. check that the downstream pressure value is stable over time (wait for about 2 minutes).
