10 CYCLE START
Cycle start is to control two gensets to start circularly. Two gensets are connected by CAN(2) or
RS485(2). Master can control backup to start/stop genset by sending commands and check backup fault
status. Master and backup can be set by parameter configurations, or decided by input setting. It is only
active in Auto mode.
Operation procedure:
a)
Master waits for start and when remote start input is active, it starts automatically. Running time is
the pre-set "Master Running" time;
b)
"Master Running" is over or shutdown alarm occurs; and when backup remote start input is active,
backup starts; when backup runs normally, master stops; backup running time is the pre-set "Obey
Running" time;
c)
In the whole process, master and backup can change current status information at real time by
CAN(2) and RS485(2); when running time is over or backup shutdown alarm occurs, master starts
and it goes like this circularly;
d)
When communication is interrupted, controller issues "Cycle Com Fail" alarm; when master remote
start input is active, master starts; when backup remote start input is active, backup starts.
11 SENSOR SETTING
1)
When sensors are reselected, the sensor curves will be transferred into the standard value. For
example, if temperature sensor is SGH (120℃ resistor type), its sensor curve is SGH (120℃ resistor
type); if select the SGD (120℃ resistor type), the temperature sensor curve is SGD curve.
2)
When there is difference between standard sensor curves and used sensor curves, users can select
custom sensor curve and input self defined sensor curve.
3)
When the sensor curve is inputted, x value (resistor) must be inputted from small to large, otherwise,
mistake occurs.
If sensor type is selected as ―none‖, sensor curve is not working.
4)
If the corresponding sensor has alarm switch only, users must set this sensor as ―none‖, otherwise,
5)
shutdown or warning may occur.
6)
The headmost or backmost values in the vertical coordinates can be set as the same as below.
