Trouble

Check if...

Solution

Linearity is not good Feedback lever is on the wrong setting

Readjustment zero, span adjustment

Wrong zero, span adjustment

Readjustment zero, span adjustment

Supply pressure is unstable

Replace regulator

Hysteresis is poor

Wrong setting of seat adjustment

Readjust seat adjuster

Loose connection of actuator and positioner

Tighten connection

Cam shaft is worn out

Replace cam shaft

Option

Pilot valve with output orifice

1. Hunting may occur when the positioner is attached to a small capacity actuator.In such case, use a

pilot valve having a output orifice for OUT1 and OUT2. The output orifice is removable.

2. Output orifice types. (Refer to description in chapter 4. Ordering Symbols.)

Volume of Actuator

Output orifice diameter

Ordering No.

Below 6 cubic inches

Ø 0.7

RO1

6~10 cubic inches

Ø 1.0

RO2

Over 10 cubic inches

None

3. After pulling out the O-ring from OUT1 and OUT2 port, push proper orifice and then mount the O-ring to OUT1 and

OUT2 again. When mounting the output orifice, pay attention not to let dust and others enter the port hole.

4. If the hunting does not stop even after mounting the output orifice, please contact us.
