Preset Maint. cycle
TUSIGN32 [2]
0 to 99999 h
Sets the service interval.
After the maintenance interval has expired, the corresponding error
message ‘Maintenance interval is reached’ is set. The setting ‘0’
deactivates the maintenance interval.
Factory setting: 0 h
3311
Maint. Remain. Time
TUSIGN32 [2]
Time remaining in the maintenance interval until the error message
‘Maintenance interval is reached’ is set.
The parameter is read only.
9001
Start New Cycle
ACTION [1]
Resetting of the maintenance interval.
By writing any value to this address, the maintenance interval is reset to
the value set under ‘Preset Maint. cycle’.

Manual stimulation of measured values / outputs.
The simulated output values correspond to the set measured value (see
Setting of the simulated measured values
on page 87).
Only one measured value / output can be selected for simulation.
After power-up / restart of the device, the simulation is switched off.
