A/M switch adjustment
1. On the right hand bottom of positioner, there is A/M switch (Auto/Manual). A/M Switch allows the
positioner to be functioned as by-pass. If the switch is
turned clockwise (toward “A”) and it is
fasten tightly, then the supply pressure will be transferred to actuator through outport by
positioner control. On the other hand, if the switch is turned counter-
clockwise (toward “M”), it is
loosened, then the supply pressure will be directly supplied to the actuator regardless of
positioner control. It is extremely important to check the allowed pressure level of the actuator
when the switch is loosened.
2. Check whether the supply pressure is too high.
3.
After using “Manual” function, A/M switch should be returned to “Auto”.
