2 Configuration Instructions
2.1 Safety Code for Operation
The actuator of the SI-RF Safety Switch system has a non-modifiable safety code for distinct and error-free identification.
This code must be submitted to the SI-RF Safety Switch and permanently saved in the SI-RF Safety Switch. Three different
coding levels are available:
• Low (L)—The SI-RF Safety Switch accepts any actuator.
• High (H)—The SI-RF Safety Switch only accepts the last taught-in actuator, a maximum of 12 teach-in processes
are possible.
• Unique (U)—The SI-RF Safety Switch only accepts the taught-in actuator, and only one teach-in process is possible.
2.2 Teach the Safety Code
1. Position the new actuator in front of the SI-RF Safety Switch.
2. Energize the SI-RF Safety Switch for minimum 5 seconds.
The amber and green LED on the SI-RF Safety Switch flash with flash code 6 for 1.5 seconds (see
on p. 21). The new actuator code is stored temporarily.
3. Disconnect the SI-RF Safety Switch from supply voltage.
4. With the new actuator still positioned in front of the SI-RF Safety Switch, again energize the switch for a minimum of
5 seconds.
The amber and the green LED on the SI-RF Safety Switch flash with flash code 6 for 3 seconds. The new actuator
code is saved in the SI-RF Safety Switch.
If a different actuator code is read on the second power-up, the temporarily stored code is lost and you must re-start the
process.
Note: If, after this process is followed, the Amber LED is still flashing BC1, disconnect the output wires. If
the Amber LED turns on solid, the outputs could be shorted to a voltage source.
