Ports Ip, P, S, C1 and C2 are sealed with plugs. To install gauges,
unscrew plugs and replace with gauges.
Port OUT is for venting the unit. All air from the positioner, actuator
and I/P unit is vented to atmosphere through this port. Do not block
this port. A high flow silencer or an exhaust pipe can be connected to
this port to prevent foreign objects from entering and blocking the
units exhaust. Connector in exhaust port must not have less than 9
mm (3/8“) orfice.
When using gases other than air for supply — Please contact PMV.
On EP5 (P5 with I/P unit installed) I/P unit is supplied with air from
