"3.4.13 Shift upper endstop"
Requirement:
The "Up" or "Up and down" option is set in the"2.1.2 Tight closing"
(Page 72) parameter.
Purpose:
Indication of the current shift of the upper endstop compared to its
initialization value.
"3.4.14 Reference value of position"
Purpose:
Indication of the reference value of the position.
Description:
The average reference value must first be calculated following
activation of the function in the "3.6.7 Average position value"
(Page 113) menu. For this purpose, an average position value is
calculated for the time set in the"3.6.7.2 Time basis" (Page 115)
parameter, and subsequently saved. This is the reference position
value which is displayed here.
"3.4.15 Average value of position"
Purpose:
Indication of last average position value calculated.
Description:
Following saving of the reference position value, an average value is
generated for the time set in the "3.6.7.2 Time basis" (Page 115)
parameter, and compared with the reference value. If the difference
between the two values exceeds one of the three parameterizable
thresholds, the device outputs a diagnostics message.
