Installation
24 — English Reflexomat with Basic controller — 20.06.2017 - Rev. C
6.3.4 Connection to an external compressed air line
An external pressure supply can optionally be connected to the Reflexomat. When doing so it must be ensured that a pressure reducer is
fitted in the external pressure line. The minimum pressure to be set depends on the relevant pressure rating of the tank.
1 Pressure reducer, site attachment PIS Pressure sensor
2 Dirt trap, site attachment SV Safety valve
3 Pressure gauge, site attachment PV Overflow solenoid valve
4 Solenoid valve, supplied by Reflex LIS Level sensor
Instead of the compressor, a solenoid valve is actuated in the external compressed air line, which releases the compressed air for the
vessel. The solenoid valve is activated by the controller. The electrical connection of the solenoid valve is made via the terminal for the
compressor in the respective controller.
Properties of the external compressed air:
• Quality
– Fluid group 2 according to the Pressure Equipment Directive 2014 / 68 EU.
– DIN ISO 8573-1 Class 1.
• Oil-free
– ATTENTION Diaphragm damage caused by oil-containing compressed air. Keep the compressed air free of oil.
• Compressed air
– ATTENTION Damage to the tank. The compressed air must be reduced to the respective tank pressure rating.
Note!
See chapter “Terminal plan” for the solenoid valve electrical connection.
