Auxiliary functions
TRAVEL.ACCU
– Path accumulator
The path accumulator records and adds up the path which the actuator piston covers. A movement of the
actuator piston is detected when the position changes by at least 1 %.
The interval for outputting messages is specified by inputting a limit for the total number of piston movements.
• To do this, a history entry is made in the HISTORY submenu. For description see “26.2.22.7. History entries in
the HISTORY submenu”.
• The status signal, which is assigned to the message, is indicated at short intervals on the display.
See also D.MSG and CONFIG.MSG in Chapter “26.2.22.5”, page 146.

The STROKE submenu specifies the total stroke of the actuator piston. The
total stroke is automatically determined during the basic setting of the device
(running X.TUNE).
In the case of an analog position sensor, the total stroke must be input by
pressing the
INPUT
key.
The interval for outputting the message can be changed in the LIMIT
submenu. A piston movement which covers 10 km has been preset at the
factory.
After NEXT.M the remaining piston movement distance is displayed until the
next message appears.
The history entries of the last 3 messages can be viewed and deleted in the
HISTORY submenu.
