AEZZP0CB - MDI-CAN - User Manual
3 HOUR-METER MEMORY SERVICE
The MDI-CAN indicator retains the Hour Meter value in its own memory
(EEPROM). In this way it is possible to transfer the machine hour meter value
into other controllers, if a replacement is required, without loss of the hour meter
record for a particular machine.
This can achieved as follows:
-
With the key Switch open, connect the ZAPI Console to controller.
-
Close the key Switch. Set the function "LOAD HM FROM MDI" to ON. This
can be found in the ADJUSTMENTS Menu. In some versions, this function
may be called "AUX FUNCTION1".
-
Open and close the key Switch.
The replacement controller will now receive and retain the machine hour meter
value of the previous controller.
It has to be considered that:
-
On default, the parameter "LOAD HM FROM MDI" is set to OFF. Therefore if
this type of function is not activated as described above, the memory of the
hour-meter will be lost at turn on.
-
To avoid this situation, if the operator forgets to set parameter, the MDI-CAN
signals the alarm "A98" for 1 minute (during this time traction is disabled).
This alarm warns the operator of the imminent cancellation of the hour meter
memory. After 1 minute, if the operator has not intervened, the hour meter of
the MDI-CAN will be re-written, with the hour meter value of the new
controller (Zero Hours if the controller is new).
