Relay Behavior after Bus Voltage Failure
If the bus voltage falls below 18 V, the relay can be switched to a parameterized state. The relay state can be defined as either pressed or released or remain in the state it had before the failure (No reaction). At the same time, the current switching position of the relay is saved in the device.
Possible settings:
No reaction:
The relay contact
remains unchanged in its current position. If time functions (staircase
lighting time function, on-delay, off-delay) are currently active,
they are canceled.
Pressed:
In the case of
a normally opened contact, the relay is closed; in the case of a normally
closed contact, the relay is opened. Running time functions are deactivated.
Released:
In the case of
a normally opened contact, the relay is opened; in the case of a normally
closed contact, the relay is closed. Running time functions are deactivated.
