Mounting accessories
6.3.1
Mounting pressure gauge
A pressure gauge can be mounted to display the set outlet pressure at the filter regulator PCRI.
1. Select the appropriate pressure gauge
2. Unscrew the plug screw at the pressure gauge connection.
3. Check that the seal on the pressure gauge is seated correctly.
4. Screw in the pressure gauge to the stop. To align, turn the pressure gauge back a maximum of one
turn.
6.3.2
Removing pressure gauge
1. Unscrew the pressure gauge from the pressure gauge port.
2. Screw in the plug screw with seal on the pressure gauge connection up to the stop.
6.3.3
Mounting control valve
Functional safety functions for safe venting can be implemented with various safety architectures by
mounting control valves at the corresponding interfaces on the flange module for safety functions
VABP.
The achievable hardware fault tolerance (HFT) depends on the flange module and the number of
control valves:
–
HFT 0: Module VABP-C13-100HFT0 -... with 1 control valve
–
HFT 1: Module VABP-C13-100HFT1 -... with 2 control valves
