Opening the front cover (see Fig. 2)
• To open the front cover, insert a slotted screwdriver in the top and
bottom cover notch and gently lift it.
• When the front cover is open, the electrostatic discharge requirements
must be respected and observed.
• After setting, the front cover must be fitted back in position.
• The set drop-out delay must be entered on the front cover.
Only touch the components after electrical discharge!

Time setting (see Fig. 3 and 4)
• DIP switch settings:
• The DIP switches are located underneath the front cover of the
safety-monitoring module (see Fig. 3 and 4).
• 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 SRB 220XV2, the
voltage supply must be interrupted for approx. 3 seconds.

5.3 Notes
Reduction of the delay time (see Fig. 5)
• To enable a premature ending of the drop-out delay,
an NC contact must be installed at the pins Y39-Y40.
• If the feedback circuit is not required, establish a bridge.
Delayed enabling circuits (see Fig. 6)
• The drop-out delay of the safety enabling circuits 37-38 and 47-48 can
be set within the range of 0...30 seconds by means of DIP switches.
The DIP switches are located underneath the front cover of the
safety-monitoring module.
• The safety enabling circuits 37-38 and 47-48 meet STOP category 1
to EN 60204-1.
• The safety enabling circuits 13-14 and 23-24 meet STOP category 0
to EN 60204-1.
