| Indicators/operating means |
| Operation indicator | LED green |
| Function indicator | LED yellow:
1. LED lit constantly: signal > 2 x switching point (function reserve)
2. LED flashes: signal between 1 x switching point and 2 x switching point
3. LED off: signal < switching point |
| Control elements | sensitivity adjustment (Adjustment to < 25% of the effective operating range) , Light-on/dark-on changeover switch |
| Electrical specifications |
| Operating voltage | 10 ... 30 V DC |
| Ripple | 10 % |
| No-load supply current | Emitter: &le, 55 mA
Receiver: &le, 40 mA |
| Input |
| Test input | emitter deactivation at +UB |
| Output |
| Pre-fault indication output | 1 PNP transistor, short-circuit protected, protected from reverse polarity, open collector, Umax = 30 V DC, Imax = 0.2 A
The output becomes inactive if the signal level has fallen below the function reserve for approx. 10 s (yellow and red LEDs flash).
If the light beam is interrupted four times during this period, the output immediately becomes inactive. |
