Code list
Error codes – Recommended action Condensed state alarm active, when prompted, ERR appears.
When error messages exist, they are displayed here.
53
Initialization time exceeded
(Init time >)
The initialization routine lasts too long.
–
The valve opens after a considerable delay.
–
The valve does not have fixed end stops (possible with a lined
control butterfly).
–
The valve has a strong tendency to hunt.
Status classification [Maintenance required]
Recommended action
–
Check supply pressure. If necessary, install a pneumatic
booster.
–
Adjust end stops.
–
Reduce tendency to hunt (e.g. restrict or open booster bypass).
Then re-initialize the positioner.
54
Initialization - internal sole-
noid valve/forced venting
1) Internal solenoid valve/forced venting not connected or
incorrectly connected.
2) If you attempt to initialize the device from the fail-safe
position (SAFE).
Status classification [Maintenance required]
Recommended action Re. 1) – Check connection and supply voltage of the solenoid
valve/ forced venting
– Re-initialize the positioner.
Re. 2) – Switch to
MAN operating mode.
– Re-initialize the positioner.
55
Transit time too short
(transit time <)
The actuator positioning rates determined during the initializa
-
tion are so short (< 0.3 s) that the positioner cannot adapt itself
optimally.
Status classification [Out of specification]
Recommended action
–
Activate the volume restriction in the positioner output.
–
Re-initialize the positioner.
56
Pin position/switch position 1) The pin position was not entered for the initialization modes
NOM and SUB.
2) The switch (ATO/ATC) is defective
Status classification [Maintenance required]
Recommended action Re. 1) – Enter pin position and nominal range.
– Re-initialize the positioner.
Re. 2) – Return the positioner to SAMSON for repair.
