CEA7 CONTROL UNIT INPUTS AND OUTPUTS | PAGE 28
NOTE:
Activation of the genset contactor is performed with a programmable time after
detecting that the engine is in operation (Times table, parameter 6), it being
possible to dephase the activation of the genset contactor and programmed
output in STABILIZED ENGINE mode.
PROGRAMMED FUMES CONTROL OUTPUT
DESCRIPTION
Programmable outputs can be congured to initiate the engine start-up process
with fumes control. This requires assigning a programmable output (Settings
table, parameters 1 to 4, value 97) that will be enabled during the start-up
process and will remain active for a programmable length of time (Times table,
parameter 33) once the engine is running.
PROGRAMMED OUTPUT PRESENT NETWORK
DESCRIPTION
Programmable outputs can be congured to monitor the network status (Settings
table, parameters 1 to 4 or 24, value 98). The output remains active once it
detects the network presence within the correct programmed operating
conditions.
5.7 EXPANSION PROGRAMMABLE OUTPUTS
The CEA7 control unit has 4 additional programmable outputs installed in the
Second Zero Suppression expansion, the operation of which can be congured to
indicate certain states (Settings table, parameters 18 to 21). Of the 4 outputs
available, 2 of them (Programmable outputs 4 and 5) are directly connected at
the terminal and the other 2 (programmable outputs 6 and 7) must be requested
as a special function. The possible congurations permitted by the programmable
outputs are the same as those explained in section 5.5.
5.8 EXTERNAL INPUTS
The CEA7 control unit allows to assign external devices CCPT100 and CCIn8
digital inputs, to different functionalities, if those devices are connected to the
communications bus of the CEA7 control unit (Programmed table, parameters 6
to 17, 22 to 23, 25 to 40, 46 to 48; values 17 to 48 -CCIn8 and CCPT100
modules inputs-).
