4.2.3 Switch­on value
When the PSSuniversal is switched on, the output assumes the switch­on value until the
module receives data for the value of the output. You can configure the outputs per channel
with the manufacturer switch­on value (default) or you can use a freely definable user
switch­on value. The manufacturer switch­on value is 0 V.
If the module does not receive any data from the module bus for 50 ms, the outputs are re­
set to the switch­on value.
Switch­on values are entered in the system software as decimal vaues. With default scal­
ing, the decimal value (n) is calculated from the analogue value at the output (U
Start
) as fol­
lows:
n = 32 767 * U
Start
/ 10 V
example:
} Switch­on values as an analogue value at the output (U
Start
):
} Switch­on value for channel 1 is to be ­8 V.
– Switch­on value for channel 2 is to be 5 V.
