Equipment for a periodic test is required if type 2 ESPE or a pressure-sensitive edge is
connected. This test is intended to detect a hazardous failure. If the SIDOOR controller's
sensor logic is configured for ESPE or a pressure-sensitive edge, the "TestOUT" function
test signal is output automatically at the terminal X100.1 or X12.
As soon as the system actively leaves the "closed" end stop (by door command) in
, a function test signal is generated automatically.
The appropriate configuration results in the following minimum test sequence duration:
t
test,min
= 2 × (t
reaction
+ t
discrepancy,min
)
The fault "8" is generated if the test operation fails. This fault must be acknowledged in
accordance with the sequential control (cf. Fault management (ATD4xxW) (Page 185)).
The figure below describes the timing of the "TestOUT" function test signal generated by the
SIDOOR controller and the timing requirements for the OSSD signal of the ESPE.
