During system tests two separate breakers/contactors with switching time below 50ms were used.
We do not recommend usage of switching elements their reaction time exceeds these values.
H
INT
:
Breaker delay default value for both breakers (MCB Delay, GCB Delay) is set to 50ms.
4. In-phase + Open Delayed Transition, Open Delayed Transition
If Setpoint
Transition
equals to
[INPH-OPEN]
or
[CLOS-OPEN],
system continues with Open
Delayed Transition after requested synchronized transition failed (sync timeout expired sooner
than both sources reached synchronized state)
GCB Delay
[s]
By means of this setpoint system gets information about breaker/contactor switching time. This value
is needed for exact sync moment/ time prediction.
Step:
0.01 s
Range:
0.01
– 60.00 s
Default:
0.05 s
MCB Delay
[s]
By means of this setpoint system gets information about breaker/contactor switching time. This value
is needed for exact sync moment/ time prediction.
Step:
0.01 s
Range:
0.01
– 60.00 s
Default:
0.05 s
H
I NT
:
Value of breaker switching time
MUST
contain all the parts of breaker delay (i.e. breaker switching
time plus switching time of relay used for breaker control).
The more exact value is given, the more exact is the sync result.
Comms Settings
ControllerAddr (1 .. 32)
[-]
Controller identification number. It is possible to set controller address different from the default value
(1) so that more controllers can be interconnected (via RS485) and accessed e.g. from Modbus
terminal.
N
OTE
:
When opening connection to the controller its address has to correspond with the setting in PC tool.
COM1 Mode
[DIRECT/MODEM/MODBUS]
Communication protocols switch for the COM1 channel.
DIRECT:
LiteEdit communication protocol via direct cable.
MODEM:
LiteEdit communication protocol via modem.
MODBUS:
Modbus protocol. See detailed description in InteliCommunication guide.
N
OTE
:
For details on comm. speed and other technical parameters please see chapter Technical Data.
For detail description see chapter Modbus protocol. Register oriented modbus is supported.
COM2 Mode
[DIRECT/MODBUS]
Communication protocols switch for the COM2 channel, if dual communication module is plugged in.
DIRECT:
LiteEdit communication protocol via direct cable.
MODBUS:
Modbus protocol. See detailed description in InteliCommunication guide.
