Error codes –
Recommended action
Condensed state message active, when prompted, Err appears.
When fault alarms exist, they are displayed here.
53 Initialization time
exceeded
(initialization time >)
Initialization cycle takes too long.
• No pressure in supply line or pneumatic leakage
• Supply air failure during initialization
Status classification [Maintenance required]
Recommended action Check attachment and air supply line. Re-initialize the positioner.
54 Initialization – Forced
venting
1. A forced venting function 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 posi-
tioner.
2. If you attempt to initialize the positioner from the fail-safe position
(SAFE).
Status classification [Maintenance required]
Recommended action 1. Check connection and supply voltage of forced venting.
Code 45 HIGH/LOW
2. Set the MAN mode in Code 0 . Re-initialize the positioner.
55 Transit time not
reached
(transit time <)
Actuator transit times detected during initialization are so short that opti-
mal positioner tuning is impossible.
Status classification [Maintenance required]
Recommended action Install a signal pressure restriction as described in section 5.
56 Pin position Initialization canceled because selected NOM and SUB initialization
modes require the pin position to be entered.
Status classification [Maintenance required]
Recommended action Enter pin position over Code 4 and rated travel/angle over Code 5 .
Re-initialize the positioner.
