Signal behaviour

At the TE input on the safety switch there must be a test
signal that meets the following conditions (cf. Fig. 3):
PSDI input (TE)
PSDI ouput (A)
The electrical input parameters are compatible with the
output parameters in compliance with EN 61 131-2
(nominal current 0.1 A and nominal voltage 24 V):
Logical "1"
Logical "0"
Permissible test
pulse duration
If the actuating element is in the enable zone and there
is no sensor error, the test input signal is forwarded to
the output with the time delayed. The output
parameters are compatible with the parameters for the
input in compliance with EN 61 131-2 type 1 or 2:
