Error codes – Recommended
action
Condensed state message active, when prompted, Err appears.
Whenfaultalarmsexist,theyaredisplayedhere.
52 Attachment • Invalid positioner attachment
• Nominaltravel/angle(Code5)couldnotbeachievedduringNOM
initialization (no tolerance downwards permissible).
• Mechanical or pneumatic fault, e.g. wrong lever selected or supply
pressure too low to move to the required position.
Statusclassication [Maintenance required]
Recommendedaction Checkattachmentandsupplypressure.Re-initializethepositioner.
Under certain circumstances, it may be possible to check the maximum
travel/anglebyenteringtheactualpinpositionandthenperforminga
MAX initialization.
After initialization has been completed, the Code 5 indicates the
maximum achieved travel or angle.
53 Initialization time
exceeded
(Init time >)
Initialization takes too long. The positioner returns to the previous
operating mode.
• No pressure in supply line or pneumatic leakage
• Supply air failure during initialization
Statusclassication [Maintenance required]
Recommendedaction
Checkattachmentandsupplyairline.Re-initializethepositioner.
54 Initialization – solenoid
valve
1)
Asolenoidvalveisinstalled(Code45=YES)andhasnotbeen
connected or not properly. As a result, actuator pressure cannot
build up. The alarm is generated when you attempt to initialize the
positioner.
2)
If you attempt to initialize the positioner from the fail-safe position
(SAFE).
Statusclassication [Maintenance required]
Recommendedaction
1)
Check connection and supply voltage of the solenoid valve (Code 45
High/Low).
2)
SettheMANmodeinCode0.Re-initializethepositioner.
55 Transit time too short
(transit time <)
Actuator transit times detected during initialization are so short that
optimal positioner tuning is impossible.
Statusclassication [Maintenance required]
Recommendedaction Checkthevolumerestrictionsettingasdescribedinsection7.2.Re-
initialize the positioner.
