Setting Options for the DIP Switch
Caution
To ensure the safety functions, regard the following instructions for
adjustment:
• DIP switches of equal numbers must have identical positions in both
rows.
• If an external device generating pulses is connected ot a safey input of
the EP-1922 module, this input must be operatined in mode “no test
pulses” (DIP switch setting ON).
• When operating in mode “no test pulses”:
- Test pulses of the external device must be shorter than 2 ms,
otherwise the safe output will be deactivated.
- Safe laying of cables can be necessary depending on the
required safety level.
Note: Use something such as a ball-point pen to set the DIP switches and avoid spiked or sharp-
edged tools.
