Multiple PEFS Cylinder Installations

Pressure Low switch

For multiple LOP cylinder installations, which have a common LOP actuation system, a single
cylinder low pressure switch may be fitted either to:

•

one of the cylinder valves’ low pressure switch ports

•

at any suitable point in the LOP actuation system

For multiple ROP cylinder installations, a cylinder low pressure

MUST

be fitted to each cylinder

valve.

Discharge Pressure Switch

For multiple LOP and ROP cylinder installations a discharge pressure switch

MUST

be fitted to each

cylinder valve to allow redundancy in shutdown should a valve fail to operate correctly.

The activation of a discharge pressure switch (opening of circuit) will initiate the Discharged LED on
the MKII display and also the Alarm LED. The Alarm sequence is linked to Engine shutdown.

This pressure switch arrangement allows the equipment to shutdown if a pneumatic or manual
actuation device is operated.

Connecting PEFS pressure switches to the control module
