CEA7 CONTROL UNIT INPUTS AND OUTPUTS | PAGE 27
The programmable output congured as programmed output for dummy load is
deactivated when higher genset power consumption than the programmed
threshold is detected (Thresholds table, parameter 33). During a set time (Times
table, parameter 26). As a condition for enabling the dummy load output, the
generator set must have the genset contactor active and the engine must be in a
stabilised state.
PROGRAMMED OUTPUT FOR ENGINE HOLD CONTROL MODE
DESCRIPTION
This functionality allows the engine to be controlled in PULL/HOLD mode
(Regulations table, parameter 18, value 3) simultaneously with the PC power
output. The programmed output in HOLD mode remains active during engine
operation.
PROGRAMMING
To activate the engine's PULL/HOLD control mode, a programmable output must
be assigned to the HOLD control function (Settings table, parameters 1 to 3,
value 25).
WATCHDOG PROGRAMMED OUTPUT
DESCRIPTION
The programmable outputs can be congured to monitor the status of the
electronics. The output remains active if the correct operation of the generator
set's control system is veried.
STABILIZED ENGINE PROGRAMMED OUTPUT
DESCRIPTION
Programmable outputs can be congured to monitor the stabilized engine status
(Settings table, parameters 1 to 3, value 96). The output remains active once it
detects the stabilized running condition of the engine after start-up (Times table,
parameter 7) including the cooling time during the stopping cycle.
PROGRAMMED OUTPUT FOR MODE
The programmable outputs congured as a programmed output for mode is
congured to indicate the mode of operation of the control unit. Possible mode
congurations include the following values:
• Control unit in locked mode.
• Control unit in manual mode.
• Control unit in auto mode.
• Control unit in test mode.
PROGRAMMED OUTPUT FOR HEATING
DESCRIPTION
This feature allows the activation of a heater when the engine temperature is
below a programmable threshold.
PROGRAMMING
The programmable outputs congured as a heating output is activated when the
measured engine coolant temperature is below a programmable threshold
(Thresholds table, parameter 29). The output will remain active until the
measured engine coolant temperature exceeds a programmable threshold
(Thresholds table, parameter 30).
PROGRAMMED OUTPUT FOR DUMMY LOAD
DESCRIPTION
This function allows the activation of a loading bank which is separate to the
installation load, to avoid the generator set operating with low-load, in order to
prevent excessive oil consumption in the engine and allow it to run with an
optimal load.
PROGRAMMING
The programmable outputs congured as programmed output for dummy load is
activated when lower genset power consumption than the programmed threshold
is detected (Thresholds table, parameter 32) during a set time (Times table,
parameter 26).
