The LC502 control unit is able to detect a
range of different system faults. The control
unit causes the red LED to flash when a fault is
detected. In some cases the control unit
switches off the affected lubrication line or all
lubrication lines. An active fault is viewed as
follows: In the main menu, select device status
<Status> and then the fault menu. Select
<Fault> in the status menu. Upon confirma-
tion, the sources of all detected faults are dis-
played. A fault can be selected in the menu to
view its details.
All fault notifications can be acknowledged
and deleted using the
key; the lubrication
process is then restarted in all lines. In some
cases this may be able to be done with an
external pushbutton (DK).
Warning!

The user is liable for damages resulting
