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 for-
warded to the output with the time delayed. The out-
put parameters are compatible with the parameters
for the input in compliance with EN 61 131-2 type 1
or 2:
≥ 11 V, < 30 V
