Setting The Switch S5 - Siemens S5-135U/155U System Manual

10.3.3

Setting the Switch S5

Select the monitoring time (between 125 ms and 1 s) by switching one of the
switches S5/1 to S5/4 to ON. If none of the four switches S5/1 to S5/4 is in
the ON position, for safety reasons the monitoring time has been set to 1 s.
If serial interface modules and the link between IM 304 and IM 314 are used,
the PESP' monitoring is to be switched off (see Section 10.1.4: Control line
faults).
Should the acknowledgement signal (RDY/) not be suppressed in the event of
a fault, the switch S5/8 must be in the OFF position.
When a BASP signal is active, the RDY/ signal will always be output.
