Leak detector Vakumatik IVF R34
- Verification of setting values of the leak detector
(see Section 4.1):
„Alarm On“ P
AE
and „Pump Off“ P
PA
.
If these values are incorrect then the correct values
can be set by means of the pressure switch (1.23).
- Verification of the values "Pump On" P
PE
and
"Alarm Off" P
AA
. These values are not set, but
rather result from the switching hysteresis of the
microswitches for alarm and/or pump control.
Specified values are reference values.
- During the functional test, check the pump / motor
(1.21) for abnormal operating noises.
- In the above mentioned valve position, the leak
detector may also be checked for leak tightness.
Interstitial space inspection (leak detector disconnected via 3-way valves):
- In the following position, the interstitial
space (12) may be checked without leak
detector, for example, for leak tightness.
Maximum pump vacuum test:
- By connecting the measuring device to
the test valve of the suction line (1.15),
the maximum pump vacuum may be
tested using the position specified on
the left.
- Pump must generate vacuum of at least
-
3
00 mbar .
