Modular Block System: Hydraulic Presses
ESPE/AOPD in guard mode with automatic function test (SB069)
Block used: SB069/AOPD_GDO
Set operating mode:
The following operating mode is set for this application:
GRP
= M116.00 (SafetyBUS p I/O-Group 0)
GdOn = 1
ESPE/AOPD as guard function with
SSeq
= 0
start-up disabler/function test and
ARSt
= 0
reset lock
The signal may come from a connected operating mode
selector switch block (e.g. SB051).
Sequence of automatic function test of the ESPE/AOPD in guard
mode:
• A 0/1-pulse edge at the input parameter
Test requests an automatic
function test of the ESPE/AOPD.
• The output parameter
TEST (ESPE/AOPD emitter) is switched off.
• As soon as both input parameters
NO_1 and NO_2 (ESPE/AOPD-
outputs) show a 0-signal, the output parameter
TEST (ESPE/AOPD
emitter) will be switched back on again (
TEST = 1).
• The test is complete when both input parameters
NO_1 and NO_2
(ESPE/AOPD outputs) show a 1-signal again, i.e. switched on.
INFORMATION
The block enable output parameter
ENBL = 1 for the whole duration of the
automatic function test of the ESPE/AOPD.
The maximum permitted duration of the whole test on Type 2 ESPE/
AOPDs is 150 ms (in accordance with EN 61 496-1 Section 5.2.4, 06/98).
