TEST:

Test output
TEST = 0: Simulated break in protected field

Automatic function test of ESPE/AOPD by
switching off the ESPE/AOPD emitter (see also
under “Function”).

TEST = 1: ESPE/AOPD emitter in operation

RdCy:

ESPE/AOPD ready for new cycle
RdCy = 0:

Cycle mode not selected or cycle mode selected
but ESPE/AOPD not ready for break

RdCy = 1:

Cycle mode selected and ESPE/AOPD ready for
break

PWR:

Output for switching the operating voltage to the ESPE/AOPD
(POWER)
PWR = 0:

ESPE/AOPD switched off
(input parameter:

OFF = 1; RUN irrelevant)

PWR = 1:

ESPE/AOPD switched on
(input parameter:

GdO or SBrk or DBrk = 1;

RUN irrelevant)

Function

• Monitoring the ESPE/AOPD inputs:

Feasibility check on N/O 1 and N/O 2 (input parameters

NO_1 and

NO_2), monitoring contact synchronisation time (DB 015/DW 1001).

• Reset pulse edge

Existing errors can be reset via a 0/1-pulse edge at the reset button
(input parameter

RSET).

• Function test:

A function test is carried out by breaking the protected field, clearing it
again and then pressing the reset button (input parameter

RSET).

In the case of hardware errors, a function test must always be carried out
after the error has been rectified.

• Start-up disabler:

A start-up disabler will be set if the PSS is switched on or monitoring of
the ESPE/AOPD is activated via the input parameter

RUN.

The lifting of the disable will depend on the set start-up procedure. The
start-up sequence is established via the input parameter

SSeq (function

test or just reset in “Guard only” mode).
