Two-channel
parameterization
Please note the following for two-channel parameterization:
Ensure that the values for the switch-off delay for stop category 1 are the same for both
channels. This means that the time must have the same value and the same value range.
Switch-off delay for stop
category 1
The
switch-off delay for stop category 1
is calculated from the "Switch-off delay for stop
category 1" and "Value range of switch-off delay for stop category 1" parameters.
Switch-off delay for stop category 1 =
Switch-off delay for stop category 1 x
Value range of switch-off delay for stop category 1

Behavior of the relay outputs in the event of
enabled switch-off delay for stop category 1
Depending on the event that causes the relay outputs to be switched off, the
parameterization of the switch-off delay, the time until the relay outputs are actually
switched off can vary.

Enable
(VersaSafe only)
Disabled
Enabled
Disabled (default value): The corresponding safe output is
operated exclusively according to the safety logic.
Enabled: Enable is active; the safe output data is output after
being ANDed with the standard output data of the standard
control system.

Remark
OUT0 - OUT1
If the switch-off delay for stop category 1 is parameterized with a value less than 150 ms,
this value is rejected as a parameterization error (error code 028x
hex
).
