STROKE.CHECK
– End position monitor
The STROKE.CHECK function is used to monitor the physical end positions of the armature. In this way wear marks
can be detected on the valve seat.
To do this, a tolerance band is specified for the lower end position (position 0 %) and for the upper end position
(position 100 %). If an end position exceeds or falls below the tolerance band, a message is output.
• 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.
In addition to the monitor there is an end position slave pointer. This indicates the minimum and maximum position
of the determined end positions. The slave pointer can be reset by pressing the
CLEAR
key.

MAX indicates the maximum position of the slave pointer

The tolerance band for the physical end positions can be set in the LIMIT
submenu. A message is output if the temperature goes outside the per-
mitted range.
Example:
Input upper end position TOL MAX = 1 %
If the position is less than -1 %, a message is output
Input lower end position TOL ZERO = 1 %
If the position is greater than 101 %, a message is output
The history entries of the last 3 messages can be viewed and deleted in
the HISTORY submenu.
