Set input on HIGH for 1 second. DV/Status output will switch to HIGH for 3 seconds and then shortly oscillate to signal that the teaching operation has been completed. Diagnostic output/Teach output. RL- Vs: High: >(+Vs -1.0 V) Low: <3.0 V RL- GND: High: >(+Vs -3.0 V) Low: <1.0 V ILmax = 10 mA Upon any short-time disturbance, DV will go on Low for 1 second. In the event of one out of both taught limits being beyond the sensing range or too close to each other, the DV/status output will oscillate shortly. There is no teaching of sensing range. The operation must be repeated under consideration of minimum teaching limit and sensing range. Encoder housing. Set / restore default Set input on HIGH for 16 seconds. (After 5 seconds, the DV/status output will start oscillating while restoring default in second 15). Note: The cable pull has to be completely drawn in.
