Measuring the evacuation time t1:
The interval between reaching the switching points SP2 and SP1 is measured (in ms).
The specified value for the max. permitted evacuation time can be set in the Extended Functions menu
with the parameter [
t-1
]. Setting the value to [
000
] (= off) deactivates monitoring. The maximum per-
mitted evacuation time setting is 9.99 s.
If the measured evacuation time t1 exceeds the specified value (>
000
), the display alternately shows
t-1
and the vacuum level.
After 5 correctly measured evacuation times, the error message
t-1
is reset. The message is also immedi-
ately deleted if you set the permissible evacuation time to the value
000
.
