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
.

Time

rP1
Measuring the leakage:
In control mode ([
ctr
] = [
on
]), the vacuum drop/leakage over a certain period of time is measured (as
vacuum drop per unit time in mbar/s) from the point when the air saving function interrupts suction after
reaching switching point SP1.
The specified value for the max. permitted leakage -L- can be set in the Extended Functions menu with
the parameter [
-L-
]. Setting the value to [
000
] (= off) deactivates monitoring. The maximum leakage
that can be set is 999 mbar/second.
If the leakage L is greater than the set value -L-, the display will alternately show
-L-
and the vacuum
level.
The
-L-
error message is reset after 5 airtight suction cycles (measured leakage value < specified value).
The message is also immediately deleted if you set the permissible leakage to the value
000
.
