Sensor function test

When an ESPE or pressure sensitive edge is connected, equipment for a periodic test is required.
This test is intended to detect a dangerous failure before the dangerous function is used. If the
SIDOOR control unit's sensor logic is configured for an ESPE or pressure sensitive edge, the
"TestOUT" function test signal is output automatically via X100.1 (ATD420W, ATD430W) or X12
(ATD401W), see Relay and field bus interfaces (Page 136).
As soon as the system exits the "opened" end stop active in Normal mode (by door command),
a function test signal is automatically generated.
The appropriate configuration results in the following minimum test sequence duration:
t
test,min
The maximum possible test sequence duration before the test fails corresponds to t
x p4601.
The fault "8" is generated if the test operation fails. This fault must be acknowledged in
accordance with the control unit (cf. Fault management (Page 304)).
The following figure describes the timing of the "TestOUT" functional test signal generated by
the SIDOOR control unit and the timing requirements for the ESPE signal from the ESPE.
