Condensed state message active, when prompted, Err appears.
When fault alarms exist, they are displayed here.
A solenoid valve is installed (Code 45 = YES) and has not been connected
1)
or not properly. As a result, actuator pressure cannot build up. The alarm
is generated when you attempt to initialize the positioner.
If you attempt to initialize the positioner from the fail-safe position (SAFE).
2)
Check connection and supply voltage of the solenoid valve (Code 45
1)
High/Low).
Set the MAN mode in Code 0. Re-initialize the positioner.
2)
Actuator transit times detected during initialization are so short that optimal
positioner tuning is impossible.
Check the volume restriction setting as described in section 7.2. Re-initialize
the positioner.
Initialization canceled because selected NOM and SUB initialization modes
require the pin position to be entered.
Enter pin position over Code 4 and nominal travel/angle over Code 5. Re-ini-
tialize the positioner.
Condensed state message active, when prompted, Err appears.
When fault alarms exist, they are displayed here.
Control loop error, the valve no longer follows the controlled variable within
tolerable times (tolerance band alarm Code 19).
• Actuator blocked
• Positioner attachment shifted subsequently
• Supply pressure no longer suffices.
Check attachment.
