Delay time
As well as the assignment of the outputs, an additional delay time can be set using the rotary
coding switch. 0/0.2 s/0.5 s/1 s and 2 s are available. This can be used, for example, to
suppress briefly occurring events and to output these only after they are pending for longer
(e.g. phase unbalance). The leading overload trip signal that can be used for advance
shutdown and protection of connected frequency converters is independent of the set delay
time and is always instantaneous.
Maximum assignment on the CubicleBUS
Up to two digital output modules with rotary coding switches can be operated simultaneously
on a CubicleBUS. For this purpose, these must be configured once in the operating mode
switch position left and once in the operating mode switch position right.
LED indicators
The LEDs indicate the current status of the six outputs. If an LED is off, the associated
output is not set. If the output is activated, the LED shows a yellow light.
