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). 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 engine must be in a stabilized state.
PROGRAMMED OUTPUT FOR ENGINE HOLD CONTROL MODE
DESCRIPTION
This functionality activates for one second the PC output, simultaneously with the
programmed output in HOLD mode, in engines controlled in PULL/HOLD mode
(Regulations table, parameter 18, value 3). 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).
OUTPUT PROGRAMMED ACCORDING TO THE STATE OF AN INPUT
The programmable outputs (associated with a programmable input) are activated
when an associated input is detected.
Possible congurations of associated inputs include the following values:
• Fuel reserve input.
• Water level input.
• Programmable input 1.
• Programmable input 2.
• Programmable input 3.
• Programmable input 4.
• Programmable input 5.
PROGRAMMED OUTPUT FOR ALARM
The programmable outputs congured as a programmed output for alarm is
activated when the control unit detects an active alarm associated to a
programmable output or has not still not been notied by the user.
PROGRAMMED OUTPUT FOR FUNCTION
The programmable outputs congured as programmed output for function are
congured to allow a functionality associated to an output already used. Possible
congurations of functions include the following values:
• Heating resistor. The output programmed to function as heating
resistor activation if the BT relay is programmed to manage the fuel
transfer pump.
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 manual mode.
• Control unit in auto mode.
