Know your Tow Tractor
Service Symbol:
It is normally off; when it appears (fixed) it shows
the request of programmed maintenance or the
Alarm state. In this case the relative code will be
displayed. The information supplied by the MDI-CAN can be
extremely useful. Failures can be quickly identified by the
Operator or Service Technician thereby finding the fastest
solution to the problem.
Hourglass Symbol:
It is normally off; it blinks when the Hour Meter is
working.
When the Key Switch is closed, the MDI-CAN makes a
general test lighting all the display liquid crystals, the led
and the backlight.
In this paragraph and in the following paragraphs the
display behavior if the ZAPI MDI-CAN adopts the
standard protocol is described. The ZAPI MDI-CAN can
also use a non standard protocol. The traction controller
decides which of the two protocols use. If the non
standard protocol is used, the traction controller decides
how to manage icons, LED, backlight and which
information write in the MDI-CAN memory.
