The function display is only active if the screw air
compressor unit’s drive motor is running.
The lubricators are fitted with one red and one
green LED. These LEDs indicate the following
operating conditions or faults to the operator.

(*) When the lubricator issues this signal, the
following message is output on the compressor
control: [Warning: Mot.lubr. sys] (also refer to the
operating instructions for the compressor control
GD Pilot TS).
If the lubricant pipe is blocked, the drive unit
increases the pressure to 6bar / 87psi. If the max.
pressure is reached, the lubricator switches to
a special programme and attempts to open the
lubrication duct with three additional lubrications
within 48 hours. If this remains unsuccessful, the
unit reports a fault.
Special lubrication
If you push the “SET” key for 10 seconds, a
special lubrication takes place; e.g. for prefilling or
flushing a soiled lubrication point.
