This section describes the terminal assignments, accompanied bysome examples of typical connections.Sections 3.1 to 3.5 contain specific instructions and technical datarelating to the individual terminals.

The two inputs and outputs are assigned to two 12-pin plug-inscrew terminals, coded to prevent reversed polarity.

For protection against shock hazards as specified in VDE 0411 part100, stranded conductors may only be connected using wire endferrules with insulating caps. Terminals which are not assigned in thefactory must not be otherwise assigned by the user. We recom-mend shielding all sensor connecting leads and earthing the shieldat one end. Earthing at both ends is recommend to avoid RF inter-ference or if equipotential bonding conductors are installed over longdistances. Sensor connecting leads should not be laid in the sametrunking as the mains power supply cable and output contact leads.

3.1 Connecting the power supply

AC voltage connection It is possible to switch between two different alternating voltageratings (see adjoining table) by means of the voltage selector switchat the side of the unit. The higher of the two alternating voltageratings (48 V or 230 V) is preset by the factory.

Set the required alternatingvoltage with the voltageselector switch.

Connect the alternatingvoltage supply to terminals2 and 3 in accordance withthe counter wiring diagram.

DC voltage connection Connect an interference-free power supply, i.e. do not use it for theparallel connection of drive systems, contactors, solenoid valves, etc.

Connect the DC voltage in accordance with the counterwiring diagram.

Fire protection: Operate the instrument using the recommendedexternal fusing indicated in the terminal diagram. VDE 0411 specifiesthat 8 A / 150 VA (W) must never be exceeded in the event of a fault.

3.2 Assignment of signal outputs „relay contacts“

Terminals 4, 5, 6 and 7, 8, 9 are no-potential changeover contacts.Terminals 10 and 11 are configured as NC or NO contacts in accor-dance with the purchase order specification. The signal outputs canbe assigned in accordance with the adjoining wiring diagram.Implementation as a pulse or continuous signal, together with thepulse time, is effected in the programming mode (lines 31, 32 and33).

The user is responsible for ensuring that a switching load of 8 A/150VA (W) is not exceeded in the event of a fault. Internal sparksuppression by means of two zinc oxide varistors (275 V). Theoutput relays of the instrument (1 relay or serveral) may only bedisengaged in total 5 x per minute at the most. Admissible clicksaccording to Interference Suppression Standard for the industrialsector. In case of a higher switching rate, the operator must takecare of interference suppression on the spot and under his ownresponsibility by observing the load to be switched.

Assign terminals 4, 5, 6; 7, 8, 9; and 10, 11 (relay contactoutputs) accordingly.

3.3 Assignment the electronic output

The electronic outputs (terminals 5, 8 and 11) are programmed bythe factory as NPN or PNP switching transistors (open collectors) inaccordance with purchase order specification. The outputs areprogrammed as pulse or continuous signals in the programmingmode (lines 31, 32 and 33).

The electronic outputs are not short-circuit proof.

Assign terminals 5, 8 and 11 accordingly.

3.4 Assignment the signal inputs

Terminals 12 to 17 are AC optocoupler inputs. Terminals 12 (track A)and 13 (track B) are pulse inputs for the main counter (XP) countingfunction.Terminal 14 is an external reset input for the main counter.Depending on what is set in the programming mode (line 40),terminal 15 serves:– as a counting stop input for the main counter (XP);– as a starting input for the time meter, or– to store the display (HOLD function) of the selected parameter.This process simultaneously disables the keypad.

Terminal 16 (XB counter) is the pulse input for the batch counter(XB). Terminal 17 is the input for resetting the batch counter.

The main counter (XP) is reset by applying an external signal (signalwidth ≥ 30 ms) at terminal 14; the batch counter (XB) at terminal 17.While an external signal is present, no counter takes place. Themethod of resetting is set in the programming mode (lines 29, 30).

Assign terminals 12 to 17 accordingly.

The maximum counting frequency is selected in the programmingmode (lines 24, 25 and 26).

For suitable encoders, see the Encoder Catalogue.

5.1 Operating modes

The operating modes are described below.

Step preset On reaching a preset value, the counter continues to count to thenext preset value. Preset values are always processed in thesequence: preset value 1, preset value 2. Any values can be chosen.Automatic resetting to the start count value can be obtained with thesecond preset value. External or manual resetting can be carried outat any time.

Main preset On reaching the individual preset values, the counter is reset to thestart count value. Preset values are always processed in thesequence: preset value 1, preset value 2. Automatic resetting to thestart count value can be obtained with the P2. External or manualresetting can be carried out at any time.

Parallel comparison On reaching the preset values, the outputs switch to continuoussignals if the respective preset value in either counting direction isexceeded. Any preset values can be chosen; they are processedindependently of each other. Pulse signals cannot be given in theparallel comparison modes.

P1- Self-adjusting preset Preset value P1 serves as a preliminary signal and functions as aself-adjusting preset. The preliminary signal always switches to theinput value before the final signal is given. Any second preset valuecan be chosen.

Zero contact The output signal B1 from the batch counter can be assigned to themain counter as a zero contact in every operating mode (line 39).The batch counter then has no output signal.

5.2 Counting modes for the main and totalizing counter

(input modes)

This counter is able to count in either direction. The countingdirection is independent of the adding or subtracting operatingmode. The exception to this is totalizing (A+B).

Up/down counting with one counting track A and an external

up/down signal on track B

Differential counting, track A adding, track B subtracting (A-B)

Any signal duration and time.

24

NE212Programming mode

Totalizing, tracks A and B adding (A+B)

The operating mode and consequent counting direction are selectedin the programming mode.

Up/down counting with two counting signals, phase-offset by

90o

The counting direction is automatically identified from the leading/lagging 90o phase offset. The internal phase discriminator performsthe necessary evaluation. Twofold or fourfold evaluation is possible.

5.3 Output responses (output modes)

Signal output response is determined by the following:– Programming of the preset value, start count value, output time, output logic and output function;– External resetting;– External counting direction control.

The diagrams below show the output signal responses.

Parallel comparsion

Operation in the subtractingmode is impractical.

Self-adjusting preset with pulse signal, without automatic reset

Input of the preset value P1corresponds to the intervalbetween the preliminarysignal and the final signal.This means that, if the finalsignal (i.e. preset value P2) ischanged, the preliminarysignal is automaticallyreadjusted.

The adding mode is set if the chosen start count value SC is lowerthan preset values P1 and P2. The subtracting mode is set if thechosen start count value SC is greater than preset values P1 and P2.The subtracting mode is impractical in operating modes 2 (parallelcomparsion) and 3 (self-adjusting preset).
