7.4 LIST OF EQUIPMENT
7.4.1 INFORMATION ON THE LIST OF EQUIPMENT
The CEM7 control unit allows the identication and monitoring of all the electronic
devices currently connected to the control unit. To do this, access the menu
Parameters->List of Equipment. Via this menu item, a list appears of all the
electronic equipment for measurements (PHR6/7 and PHG6/7) and display
(CEM7, CEA7, CEC7 and CEC7.2) currently connected, with an asterisk ()
indicating the module from which the list of equipment is being viewed.
The information relating to this equipment includes:
• The electronic module model.
• The electronic module ID number (from 0 to 14).
• The rmware version .
• For the display modules (CEM7, CEA7, CEC7 and CEC7.2), the
associated measuring equipment is indicated in brackets. For display
modules (CEM7 and CEA7), the Master display module must have the
same ID as the associated measurement module. For repetitive display
modules, the module must have a different ID than the master display
and must be associated to the same measurements module. For
switching control unit display modules (CEC7 and CEC7.2) the display
module must have the same ID as the measurements module of the
associated switching control unit and in brackets the ID of the genset
measurements module to which the manual control unit is associated.

7.2 MAINTENANCE COUNTERS
The CEM7 control unit has 3 programmable counters that are loaded for a certain
time which decreases while the engine is detected as running. The maintenance
counters are:
• 2 engine maintenance counters. When the counters reach zero an
engine alarm is generated without stopping. The alarm disappears
when the associated counter is reset. An engine running time that
exceeds the programmed maintenance counter is shown ashing on
the interface of the control unit with the “-” sign in front of the counter
value.
• 1 rental counter. The counter generates an alarm that can make the
engine stop. The alarm disappears when the rental counter is reset.
An engine running time that exceeds the programmed rental counter is
shown ashing on the interface of the control unit with the “-” sign in
front of the counter value.
The operation of the maintenance counters allows:
Programming. The maintenance counter is programmed from the Counters
menuMaint.#1, Maint.#2 and Rental. By pressing the key the different
operating time values in hours are reset. In the case of the rental counter, after
programming the operating hours limit, the alarm mode must be entered; the
following values are allowed:
• 0: warning.
• 1: stop without cooling.
• 2: stop with cooling.
Display. The remaining operating time before a maintenance alarm is generated
is displayed in the Counters menu->Maint.#1 in hours and minutes.
Notification. To report the maintenance alarm, it must be programmed from the
Counters menuMaint.#1 pressing the key and writing any value other than
zero.
