D-200 MK2 User Manual Firmware V-6.3
L058D01-EN - 122 -
Dual genset intermittent operation consists of regular switching of the load between 2 gensets. The use of
2 gensets instead of one is due either to safety purposes in case of a genset failure or to a continuous
operation requesting service stops.
The running period for each genset is adjustable using
Flashing Relay On Timer
and
Flashing Relay
Off Timer
program parameters. If the time is adjusted as 0 hours, it will be actually set to 2 minutes for
faster testing purposes.
A flashing relay output function is provided, based on the parameter
Flashing Relay On/Off Timers
.
Each time the period programmed using
Flashing Relay Timer
elapses, the relay output will change
position.
The flashing relay function may be assigned to any digital output using
Output Configuration
program
parameters.
The dual genset intermittent operation uses also the
Disable Auto Start
feature. Please review related
chapter for a detailed explanation of this feature.
Priority In Dual Genset Mutual Standby Operation:
It may be required that the dual genset system starts the same genset at every mains failure. This is
achieved using the PRIORITY input.
Any digital input may be assigned as
Priority
using
Input Function Select
program parameters
.
It is also necessary to set the
ACTION
program parameter of the related input to
3
in order to prevent any
alarms generated from this input.
The
Priority
signal may be a NO or NC contact, switching to either battery positive or battery negative. These
selections are made using the programming menu.
If a
Priority
input is defined, then the system will work in priority mode. If the priority signal is applied, the
unit will become master after each mains failure. If the priority signal is not applied, then the unit will
become the slave one and the other genset will start.
Please contact DATAKOM for a complete application
manual.
