The control signal could be the same as the auxiliary/control voltage of A1 or any other voltage between 12 and 240 V AC or DC. Operating a parallel load between B1 and A2 is also possible. If with function IF the inputs A1 and B1 are controlled simultaneously a pulse with the adjusted length is started. With the variant MK7850N/ 500 the output pulse can be disabled by setting the slide switch in Position "B". Time interruption and time addition with X3 On all functions, also with RV,IF, AW (EW/AW) and AB/RV the time delay can be interrupted during timing by bridging the terminals X2 - X3. By opening the bridge the time continues (time addition). While X2 and X3 are bridged the control input is disabled and the yellow LED remains in the state it had at stop. No external voltage must be connected to X2 and X3 as the unit may be damaged.

For operating voltage > 24 V and usage of sensors without built-in short circuit protection a protection resistor on A1 is recommendend to reduce the inrush current. The dimension is as follows: Remote potentiometers Both settings on variant MK 7850N/500 can also be made by remote potentiometers of 10 kOhms: - terminals Z1 - Z2: potentiometer for time t1 - terminals Z2 - Z3: potentiometer for time t2 When connecting a remote potentiometer the corresponding potentiometer has to be set to min. If no remote potentiometers are required the terminals Z1-Z2 resp. Z2-Z3 have to be linked. The wires to the remote potentiometers should be installed separately from the lines with mains voltage. If this is not possible, a screened cable is recommendet where the shield is connected to Z2. To terminals Z1, Z2 and Z3 no external voltage must be connected, as the unit might be damaged. Additional function With the variant MK7850N/500 additional features can be selected for the functions position 3, 4 and 7 using the slide switch S1 on the relay front in position "B". At the same time a second time setting t2 is available on the lower potentiometer (see function diagram) the time range is the same as for t1. Setting Rv operating voltage / max. switching current of sensor green LED on when voltage connected The series resistor must not be selected higher than necessary. Max. values are: Operating voltage: 48 V 60 V 110 V 230 V Series resistor R v max: 270 390 680 1,8 k (1 W) Instantaneous contact By external wire links the output function of the device can be altered from 2 delayed contacts to 1 delayed and 1 instantaneous contact. The instantaneous contact switches when the operating voltage is connected. To terminals X1 and X2 no other voltage potentials must be connected, as the unit might be damaged. yellow LED function see indicators range selector switch time setting t1 function setting slide switch S1 (only with MK7850N/500) Adjustment assistance The flashing period of the yellow LED is 1 s 4 % and can be used to adjust the time. Especially on the lower end of scale and for long times it is suitable as the multiplication factors between the different time ranges are exact without tolerance. Example: The required time is 40 min. It has to be adjusted within range 3 ... 300 min.The time check takes too long as several timing cycles would be necessary for a precise value. For faster adjustment the setting is made to 0.03 ... 3 min. On this range the potentiometer should be set to 0.4 min (= 24 sec.). With the right potentiometer setting the LED must show 24 flashing cycles. After that the time range is switched over to 3 ... 300 min. and the setting is complete. time setting t2 (only with MK7850N/500) M8302_a Time interruption / time adding with B1 With the functions AV, EW, IE and BI the time delay can be interrupted by controlling input B1 (+) with control voltage. Removing the control signal will continue the timing cycle (time addition). 3 Technical data Technical data Time circuit Time ranges: Time setting t1, t2: Recovery time: at DC 24 V: at DC 240 V: at AC 230 V: Repeat accuracy: Voltage and temperature influence: 8 time ranges in one unit, settable via rotational switch 0.02 ... 1 s 0.3 ... 30 min 0.06 ... 6 s 3 ... 300 min 0.3 ... 30 s 0.3 ... 30 h 0.03 ... 3 min 3 ... 300 h continuous, 1:100 on relative scale (t2 only at MK 7850N/500) approx. 15 ms approx. 50 ms approx. 80 ms 0.5 % of selected end of scale value + 20 ms < 1 % with the complete operating range Clearance and creepage distances overvoltage category / contamination level: EMC Electrostatic discharge: HF-irradiation: Fast transients: Surge voltages between wires for power supply: between wire and ground: HF-wire guided: Interference suppression: Degree of protection Housing: Terminals: Housing: Vibration resistance: Input Nominal voltage U N: Voltage range: Release voltage (A1/A2) AC 50 Hz: DC: Climate resistance: Terminal designation: Wire connection Screw terminals (integrated): AC/DC 12 ... 240 V 0.8 ... 1.1 UN Delayed contact approx. 7,5 V approx. 7 V Instantaneous contact approx. 3 V approx. 3.3 V 4 kV / 3 IEC 60 664-1 (4 kV / 2 at MK 7850N.82/61) 8 kV (air) 30 V / m 2 kV 2 kV 4 kV 10 V Limit value class IEC/EN 61 000-4-2 IEC/EN 61 000-4-3 IEC/EN 61 000-4-4 IEC/EN IEC/EN IEC/EN B 61 000-4-5 61 000-4-5 61 000-4-6 EN 55 011 IP 40 IEC/EN 60 529 IP 20 IEC/EN 60 529 Thermoplastic with V0 behaviour according to UL subject 94 Amplitude 0,35 mm, frequency 10 ... 55 Hz,IEC/EN 60 068-2-6 40 / 060 / 04 IEC/EN 60 068-1 EN 50 005 DIN 46 228-1/-2/-3/-4 1 1 2 2 x 4 mm2 solid or x 2.5 mm2 stranded ferruled or x 1.5 mm2 stranded ferruled or x 2.5 mm 2 solid AC 50 Hz: DC: Max. permitted residual current with 2-wire proximity sensor control (A1-A2) up to AC/DC 150 V: AC resp.
