7 Error code and Troubleshooting
7.1
Error code during Auto calibration
Error code as below is displayed on LCD if an error occurs during Auto calibration.
Check the error code and refer to the table below to solve the problem.
No Error Code
Cause
Solution
1
STEP0 V0
Displayed when the valve
does not stop after a long
period of time when the data
is measured to detect the
first stop of the valve during
auto calibration.
And it is mainly caused by
damage to Main board.
Replace Main PCB.
2
STEP1 PZ
Displayed when Zero point is
lower than allowable range.
Check the status of the positioner
installation or reinstall the
positioner.
Set initial angle (Zero point) of the
lever higher than the current
status.
3
STEP2 PE
Displayed when End point is
higher than allowable range.
Check the installation status of the
positioner or reinstall the
positioner.
Set final angle (End point) of the
lever lower than the current
status.
4
ACT TYPE
Displayed when Zero point
and End point of the lever
are too close or equal.
Check the status of supply air.
Unplug the potentiometer cable in
the positioner and reconnect it to
Main board.
Check the status of feedback
lever installation. And set the
operation angle that between
initial angle(Zero point) and final
angle(End point) over 40 degree.
Replace Main PCB.
5
STEP3 CT
Displayed when Close time is
too long during auto
calibration.
Check the status of feedback
lever installation.
If Zero point of the valve changes,
please conduct auto calibration
2~3 times.
If the actuator size is too big,
please set TbL value as TbL 4
LLS and conduct auto calibration
again. (Refer to page37)
