6.3.2. Time setting

• The drop-out delay of the safety enabling circuits 37-38 can be set within the range of 0...30 sec-
onds by means of DIP switches. The DIP switches are located underneath the front cover of the
safety-monitoring module.
• The safety enabling circuit 37-38 meets STOP category 1 to EN 60204-1.
• The drop-out delays of the safety enabling circuits STOP 1 can be reduced in case of a failure.
• The safety enabling circuits 13-14 and 23-24 meet STOP category 0 to EN 60204-1.
DIP switch settings:
• The DIP switches are located underneath the front cover of the safety-monitoring module
• Both DIP switches SW 1 (channel 1) and SW 2 (channel 2) must be set identically.
• The DIP switches can be set when the operating voltage is on; however, in order for the setting to be saved
in the SR4D3B01S the voltage supply must be interrupted for approx. 3 seconds.
• The set drop-out time delay period must be checked and written down on the front panel and entered into
the setting log.
• The functionality of the setting must be checked

6.3.3. Cross-circuit monitoring

• The cross-wire short monitoring function (factory setting) is programmed by means of switch S1 under-
neath the front cover of the safety-monitoring module.
• The switch must only be operated in de-energised condition by means of a finger or an insulated blunt tool.
