If you want to use the feature to “freeze” the regeneration cycle when the compressor runs
unloaded, connect pin 1 and 2 of connector X3 with the potential free contact of the
compressor (contact closed = freeze).
• CAN-Bus connection
The timer card can be interconnected in a LAN with other Elektronikon® controllers.
Addressing and CAN protocol used are the same as for the Elektronikon regulators.
Because the timer card has no programming features however, the exchanged information
is pre-configured and cannot be redefined.
Application: data communication between timer cards, MkIV Elektronikon regulators and
service PC.
