range of the compressor module.
3.3 Peripheral devices
Terminal strip CN4
HS.95 and OS.95 compressors
Option: Voltage supply of the
solenoid valve in the oil return
line (M40)
Voltage output corresponds to the selected operating voltage.
Semiconductor switch, not potential-free

at 115V.
OS.85
Option: Voltage supply of the
solenoid valve in the oil return
line from the secondary oil sep-
arator (M41)
Voltage output corresponds to the selected operating voltage.
Semiconductor switch, not potential-free
Use a solenoid coil or relay with maximum power consumption of 12W at
230V / 14W at 115V.
