• 

The electrical connection of the device shall be 
performed according to relevant VDE  and  local 
electricity board regulations. 

• 

Disconnect  the  system  from  the  mains  before 
connecting the device. 

• 

Add a fuse adapted to the energy requirements.

4.2.2 

Numbered cables 

For  models  with  numbered  cables,  the  cable  num-
bers  correspond  with  the  presented  terminal  num-
bers. 

 

Commissioning 

All electrical supply, operating and measuring lines, 
and the pressure connections must have been cor-
rectly  installed  before  commissioning.  All  supply 
lines are  arranged so  that  there  are no mechanical 
forces acting on the device. 

Check  that  the  pressure  connections  do  not  leak 
before commissioning. 

5.1 

Control Elements 

 

5.2 

Zero point correction 

 

Depressurize the measuring chamber. 

 

Remove the hood 

 

Set the measurement value pointer to the zero-
point  scale  using  the  zero  point  correction 
screw. 

 

Re-mount the hood. 

5.3 

Switch point setting 

 

Remove the plug in the hood. 

 

The  required  switch  points  can  be  set  guide 
value  scales  according  to  the  markings  by  us-
ing a screwdriver. The achievable setting accu-
racy is ± 5 %.

Replace the plug after completing the settings. 

5.4 

Function test 

Remove both plugs in the hood for testing.  

If  the  unit  has  two  micro-switches,  the  stated  test 
steps must be carried out for both switches. 

After  the  test,  the  switch  points  need  to  be  reset 
acc. to 5.3. 

5.4.1 

Checking the switch points when the 
system is depressurized.  

No  measurement  is  shown  and  the  measurement 
display points to zero. 

Turn the switch point setting button toward the zero-
point until the micro-switch is activated.
