The setting has to be done during the first 30 seconds after switch on of the ignition. After a
change of the settings, either the ignition has to be switched off and on again or an intermediate
lubrication has to be triggered.

Function sequence

The EP-tronic T1 is a control unit for trailers and semi-trailers and does not require a permanent
current supply. It has five voltage inlets which serve for recognition of the vehicle movement. The
three voltage inlets tail light, brake light and flashing alarm light serve as current source.
At the control unit EP-tronic T1 is the length of the lubrication time and the cycle time adjusted. As
the pump does not have a permanent current supply, it can only lubricate, if one of the three
voltage connections is supplied with current. Therefore can the total lubrication time sum up of
several short lubrication times.
If the lubrication time is not completed during the cycle time, the remaining lubrication time is
taken over to the next cycle. The maximum to which the lubrication time can sum up is the double
of it.
If there is no voltage recognized at none of the five voltage inlets for more than half an hour, the
cycle time is stopped. The control unit assumes that the vehicle is no longer in motion.
The total lubrication time sums up of several short ones:
SZ1 SZ2 SZ3 SZ4
Cycle time (ZZ)
SZ1 + SZ2 + SZ3 + SZ4 = sum of lubrication times
