Check and set pressure monitor
Deadly risk!
Working on open, live equipment!
• Do not operate the equipment with damp hands!
• Caution: live components!
Setpoint value switching pressure
Compressor On = 3.0 bar
Off = 5.5 bar
Check switch values
• Switch on operating voltage.
• Close shut-off valve (
9 ).
• Open safety valve "high pressure" ( 25 ) and observe
manometer "high pressure" ( 13 ).
- with a pressure drop below 3.0 bar the compressor must
start.
• Close safety valve "high pressure" ( 25 ) and observe
manometer "high pressure" ( 13 ).
- with a pressure increase to 5.5 bar and furthermore the
compressor must switch off.
To set the switch values note the following:
•
Only set pressure monitor (36) under pressure! 9 25 36
• Rotating the hand valve (81) causes approx. 0.6 bar change of switching pressure.
• First set the cut-out pressure and then the cut-in pressure, because changing the cut-out pressure
leads to a change in the cut-in pressure. This means the difference between cut-out and cut-in
pressure stays the same.
• Once the hand valve has been pressed down (81) the cut-in pressure can be adjusted separately
and the difference between the cut-out and cut-in pressure changed.
Set the switch values
• Lift up the plastic cover of the pressure monitor after
unfastening the four screws.
• Unscrew the lock pin ( 82 ) of the hand valve ( 81 ).
Set the cut-out pressure:
Raise cut-out pressure
• Turn hand valve ( 81 ) clockwise (pr)
Lower cut-out pressure
• Turn hand valve ( 81 ) anti-clockwise (pressure -) 81 82
Set the cut-in pressure:
Raise cut-in pressure
• Press down hand valve ( 81 ) and then turn clockwise
(difference -)
Lower cut-in pressure
• Press down hand valve ( 81 ) and then turn anti-clockwise
(diff)
After setting
• Screw in lock pin ( 82 ) in one of the two retainers.
• Put on the cover of the pressure monitor again and tighten.
