Description
Totaled full valve travel cycle
Can be reset to 0 in Code 36 – STD and Code 36 – DS.
Note: The total valve travel is saved in a non-volatile memory after
every 24 full valve travel cycle.
Limit of total valve travel limit
'Total valve travel exceeded' message is generated depending on
7
selected status classification if the limit is exceeded.
Note: The 'Total valve travel exceeded' message has the default
status classification ' alarm required'. This classification can only
be changed in the operator software (e.g. TROVIS-VIEW).
Switching mode of software limit contact alarms A1 and A2 when
activated (when the positioner is initialized).
Explosion-protected version according to EN 60947-5-6
0: A1 ≥ 2.2 mA
1: A1 ≤ 1.0 mA
2: A1 ≥ 2.2 mA
3: A1 ≤ 1.0 mA
Version without explosion protection
0: A1 R = 348 Ω
1: A1 non-conducting
2: A1 R = 348 Ω
3: A1 non-conducting
When a positioner has not been initialized, the software limit con-
tacts always register the signal as in the state of no response.
If there is no mA signal at the terminals 11/12, the software limit
contacts both switch to ≤ 1.0 mA (Ex) or non-conducting (without
explosion protection).
Note: The fault alarm output always switches to ≤ 1.0 mA/
non-conducting in case of a fault; it has ≥ 2.2 mA/R = 348 Ω
when there is no fault.
