9-11 Modular Block System: Hydraulic Presses
• On parallel muting with sensors (i.e. no star arrangement of MP1 and
MP2), it was previously possible for the enable ENBL from SB 072 to be
reset and error bit 02 to be set, if gaps in the load occurred when the
ESPE/AOPD was released. This no longer happens.
• Reset with sequential muting
If an error occurred (e.g. TS12 elapsed, TMut elapsed, MS1 and MS2
simultaneously) after the start-up of MS1 (ESPE clear) or MS1 and MS2
(ESPE interrupted), previously, a reset was only possible if MS1 was
released.
Releasing MS1 was often not possible with muting channels, because
“reverse travel” was technically impossible and further “forward travel”
was prevented as there was no enable from SB 072. The enable,
however, is only triggered after a reset.
Now, a reset is also possible in these cases, so that the enable from
SB072 can again be accessed.
• Gaps in the load with sequential muting
When reaching sequential muting mode, muting was previously aborted
if the ESPE/AOPD was released for longer than the time stated under
TInt.
There is now no time limit on the release of the ESPE, provided both
muting signals MS2 and MP1 are used with the vehicle. If just one of the
muting signals is used, e.g. on entering and leaving, the gaps may not be
longer than
TInt, as previously.
SB075: Controlling and monitoring safety gates with guard locking
SB085: Driving and monitoring a hydraulic directional control valve
SB085 is no longer included in the MBS Hydraulic Press package from
Version 2.0. It has been replaced by SB087.
