Adapting The Display Direction; Limiting The Signal Pressure - Samson 3730-4 Mounting And Operating Instructions

The position of volume restriction Q also depends on how the signal pressure is routed at the
actuator in SAMSON actuators:
'SIDE' inscription
For actuators with a signal pressure connection at the side, e.g. Type 3271-5
–
For actuators from other manufacturers
–
'BACK' inscription
− For actuators with a signal pressure connection at the back, e.g. Type 3277-5
NOTICE
!
Malfunction due to changed start-up settings.
Initialize an initialized positioner again after the position of the volume restriction has been
changed.

7.3 Adapting the display direction

The display contents can be turned by 180° to adapt the display reading to the actuator's
mounting situation. If the displayed data appear upside down, proceed as follows:
1. Turn until Code 2 appears.
2. Press , the code number 2 blinks.
3. Turn and select the desired reading di-
rection.
4. Press to confirm.

7.4 Limiting the signal pressure

If the maximum actuator force may cause damage to the valve, the signal pressure must be
limited.
Î Do not activate pressure limitation for double-acting actuators (AIR TO OPEN (AtO) fail-
safe position). Default setting is 'No'.
Enable configuration at the positioner before limiting the signal pressure.
