1. For tanks with suction line to the low point:
The suction line must lead either in the interstitial space or on the outside of the tank (but
then pressure-resistant) from the low point of the interstitial space to above the interstitial
space and also above the max. tank filling level.
2. Installation example A
– 01:
Here, the probe is drawn with a dotted line for the version VL .. E in order to show the differ-
ent possibilities.
3. Installation example H
– 01:
This series connection is
ONLY
permitted and possible for the tank type(s) listed in
Appendix E.4.
4. Installation example K
– 01:
The exhaust pipe ends in a non-dangerous position.
The following possibilities are available for monitoring these shafts:
– Double-walled pipe around the hydraulic cylinder, suction line in the interstitial space lead-
ing to the low point.
– Interstitial space between the single-wall pipe and hydraulic cylinder, with the suction line
leading to the low point of the interstitial space.
– Suction and measuring line connected to the highest point of the interstitial space. In addi-
tion, probe at the low point of the interstitial space. This means the shaft can be as deep as
required.
5. Start-up
(1) Heed and observe specifications in chapter 4.
(2) Carry out pneumatic connection.
(3) Set up electrical connection, do not apply voltage supply yet.
(4) Close the housing cover.
(5) Apply voltage supply.
(6) Establish lighting up of operating and alarm lamp as well as the audible alarm signal. Press
the "mute" button, the signal lamp "alarm" will blink.
(7) Only VL .. E with solenoid valve: carry out the start-up sequence (see chapter 3.5.2).
(8) Three-way valve 21 in position "III", connect measuring gauge. (cf. P-060 000)
(9) Apply vacuum to the system.
To do this, the installation pump can be connected to the muff on three-way valve 20, posi-
tion IV. Switch on the installation pump. The interstitial space will be evacuated. Monitor the
vacuum build-up on the measuring gauge.
NOTE: If no pressure is built up with the installation pump connected, the leak must be lo-
cated and eliminated (if necessary, check the feed capacity of the pump and/or the position
of the three-way valve).
(10) Once the leak detector has reached operating vacuum (pump in the leak detector switches
off), the three-way valve must be set to position I, the installation pump switched off and
removed.
(11) Three-way valve 21 in position "I", remove the measuring gauge.
(12) Carry out the functional test according to section 6.4.
