Create status object “Status Switch”
*
yes
no
If this parameter select ‘yes’, ETS create another communication object for use only status switch.
The status object can be used to display the current output switching status on a display.
Send status after bus voltage return
yes
*
no
You can use this parameter to send the switching state in the event of bus voltage recovery.
Behaviour after ETS program
*
keep position
open contact
close contact
After ETS programming, relay position set the wanted switching position.
§
Set the parameter to “keep position”
In this setting, the relay remains in the current state. Any manual operation occurs in the
meantime the switch actuator return its old position. The device doesn’t know the status of the
relay.
§
Set the parameter to “open contact” or “close contact”
The relay contact open or close after bus voltage return.
Behaviour bus voltage failure
*
keep position
open contact
close contact
When the bus voltage fails, the device set the wanted switching state of the output. The relay can be
open, close or keep position it occupied prior to the failure. At the same time, the current switching
position of the relay is stored in the devices.
Behaviour bus voltage return
keep position
open contact
close contact
*
state as before bus voltage failure
When the bus voltage returns, the device set the wanted switching state of the output.
§
Set the parameter to “keep position”
In this setting, the relay remains in the current state. Any manual operation occurs in the
meantime the switch actuator return its old position. The device doesn’t know the status of the
relay.
§
Set the parameter to “open contact” or “close contact”
The relay contact open or close after bus voltage return.
§
Set the parameter to “state as before bus voltage failure”
If the parameter set to “state as before bus voltage failure”, then the relay is set to the value.
The value stored at the time of the bus voltage failure.
