Relay
According to “Relay Control” field, the potential free relay output can be used to :
•
Either control of a gen-set depending on the SoC (state of charge)
•
Or control a switch based on voltage to switch On and Off a source according to an operating window.
Note : It is possible to test the relay function by pressing Manual test.
When
Relay control
is
Capacity
, following settings are available:
Note : When
pulse mode
is selected the Gen set has to
be stopped manually.
1: Capacity On Level
When mode is Passive (N.O.), relay is active when
actual capacity of channel selected falls under this
level
2: Capacity Off Level
When mode is Passive (N.O.), relay is inactive when
actual capacity of channel selected rises over this
level
3: Channel
Select the trigger source (shunt)
When
Relay control
is
Voltage
, following settings are available:
Note :
Pulse mode
is not available in Voltage control.
1: Undervoltage
When mode is Passive (N.O.), relay is active when
v1 of channel selected falls below this level.
Relay is inactive when actual voltage rises above this
level (+0.6V hysteresis)
2: Overvoltage
When mode is Passive (N.O.), relay is active when
v1 of channel selected rises above this level.
Relay is inactive when actual voltage falls below this
level (-0.6V hysteresis)
3: Channel
Select the trigger source (shunt)
