CEC7 CONTROL UNIT INPUTS AND OUTPUTS | PAGE 17
6.2 PROGRAMMABLE INPUTS
The CEC7 control unit's measurements module has 3 digital inputs with operation
that can be programmed. The programmable inputs can be congured to have
the following behaviour:
Confirmation of network contactor (CKR)
The input congured as network contactor conrmation (Settings table, parameter
5) is used to verify the correct activation of the network contactor. Upon activation
of the network contactor, a time interval begins (Times table, parameter 13) for
verication of the contactor through the activation of the network contactor
conrmation input. If after this time has elapsed there is no conrmation of the
activation of the network contactor and the control unit does not detect a network
failure alarm, a network contactor alarm is generated (Alarms table, parameter
100). If the control unit is operating in automatic mode, the genset is started
with activation of the genset contactor for the supply of the installation.
Confirmation of genset contactor (CKG)
The input congured as genset contactor conrmation (Settings table, parameter
6) is used to verify the correct activation of the contactor. Upon activation of the
genset contactor, a time interval begins (Times table, parameter 13) for
verication of the contactor through the activation of the genset contactor
conrmation input. If after this time has elapsed there is no conrmation of the
activation of the genset contactor, a genset contactor alarm is generated (Alarms
table, parameter 102). If the control unit is operating in automatic mode, a stop
occurs with engine cooling and activation of the genset contactor if it is within
the valid operating parameters.
Enabling of genset contactor activation (HKG)
This function is only managed in automatic mode of the CEC7 control unit. The
input congured as enabling genset contactor activation (Settings table,
parameter 8) inhibits the activation of the genset contactor until the input is
active after stabilization of the genset electrical signal.

The value of the resistance analogue inputs is shown in ohms and the voltage
analogue inputs in volts. The various inputs displayed are:
• NC: Fuel level.
• PA: Oil pressure.
• TM: Engine temperature.
• AA: Auxiliary analogue.
• DI: Alternator voltage.
• VB: Battery voltage.
6.1 DIGITAL INPUTS
Emergency stop (PEM)
Digital signal notifying the control unit that an immediate stop of the engine must
be performed without cooling.
