Adjustment
– A/M switch (Auto/Manual)
1. Auto manual switch is on the top of pilot unit. Auto manual switch allows the positioner
to be functioned as by-pass. If the counter-clockwise (towa
rd “M”, Manual), it is
loosened, then the supply pressure will be directly supplied from out1 port of positioner
to the actuator regardless of input signal ampere. On the other hand, if the switch is
turned clockwise (toward “A”, Auto) and it is fasten tightly, then the positioner will operate
normally by input signal ampere. 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, auto manual switch should be returned to “Auto”.
