CEA7 CONTROL UNIT INPUTS AND OUTPUTS | PAGE 22
PROGRAMMABLE ALARMS (AL4 AND AL5)
There are 2 additional programmable alarms available (Settings table, parameters
22 and 23) that can be associated with any of the programmable inputs and
which serve the purpose of providing the control unit with additional alarms with
congurable operation (Alarms table, parameters 111 to 116). These alarms can
be programmed both with regards the mode of action as well as the text shown
on the display when activated.
PROGRAMMABLE ALARMS (AL6 to AL20)
15 additional programmable alarms are available (Settings table, parameters 26
to 40) that can be associated with any of the programmable inputs and whose
purpose is to provide the control unit with additional alarms with congurable
operation (Alarms table, parameters 207 to 251). These alarms can be pro-
grammed both with regards the mode of action as well as the text shown on the
display when activated.

SELECTION OF SET OF PARAMETERS (S1 AND S2)
There are 2 sets of additional parameters that can be enabled via any of the
programmable inputs (Settings table, parameters 16 and 17). Activating the
parameter set selection input enables the values with which the control unit
operates (Selector table).
REGENERATION REQUEST
The input congured as forced regeneration request of the genset (Settings ta-
ble, parameter 46) is used to request catalyst regeneration in engines that com-
ply with STAGE V/TIER FINAL 4 regulations.
REGENERATION INHIBITION.
The input congured as forced regeneration inhibition of the genset (Settings ta-
ble, parameter 47) is used to disable the catalyst regeneration in engines that
comply with STAGE V/TIER FINAL 4 regulations.
TEST SIGNAL (TEST)
This function is only managed in automatic mode of the CEA7 control unit.
The input congured as test (Settings table, parameter 11) allows a check of the
genset to be performed without activation of the load.
FORCED OPERATION (MFOR)
This function is only managed in automatic mode of the CEA7 control unit.
The input congured as forced operation (Settings table, parameter 12) complies
with anti-re regulations according to which it should not stop the operation of
the genset under any condition except overspeeding and emergency stop
(whether this is alarm, external start up disabling input or programmed block). It
is possible to congure 3 modes of forced operation (Regulations table,
parameter 25):
• 0: Forced operation not enabled. The process of forced operation is
not managed despite having an associated programmable input.
• 1: Starting due to network failure. Before activating the forced
operation input, the system waits for the start to occur due to a
programmed condition (alarms related to network signal, network
contactor failure, external start up...) needed to start the genset. To
stop the genset it is not sufcient that the start condition disappears,
but the input associated with the forced operation must be disabled.
• 2: Starting due to forced operation. Before activating the forced
operation input, the genset starts immediately without the need to wait
for any other start condition to occur. To stop the genset, it is necessary
to switch to manual operating mode and in this mode perform the stop
using the control unit keyboard, pressing the stop button.
PROGRAMMABLE ALARMS (AL1, AL2 AND AL3)
There are 3 programmable alarms available (Settings table, parameters 13, 14
and 15) that can be associated with any of the programmable inputs and which
serve the purpose of providing the control unit with additional alarms with
congurable operation (Alarms table, parameters 79 to 87). These alarms can be
programmed both with regards the mode of action as well as the text shown on
the display when activated.
