Installation

1. Mounting the unit

Mount the unit in a suitable place so the terminals and the switches are accessible. The unit is prepared for DIN-rail mounting.

2. Supplying the unit

Connect terminal 1 and 2 to +24 VDC and ground, respectively. Connect the sensor head UC80CND80FSM1 to the terminals 3, 4, 5, 6 and 8 according to the wiring diagram.

3. Programming the unit and the sensor head UC80CND80FSM1

Make the settings on the unit according to the following description.

Front Panel

This chapter gives a brief description of the switches and the LED's, which are all placed on the front panel.

Switches and LED's on the front panel

LED's

• SP1 ON when Setpoint 1 is active.
• SP2 ON when Setpoint 2 is active.
• U_B ON when power is applied.
• OVER ON when the measurement exceeds the programmed range.
• UNDER ON when the measurement is below the programmed range.

Digital switches

The two setpints can be adjusted individually with these 2 groups of 3 digital switches (1 hexadecimal and 2 decimal switches in each group). The resolution is in mm.

10^2 = hundreds switch
10¹ = tens switch
10° = units switch

Examples:

4, 0, 0, means a setting of 400 ~mm . With this setting of the switches to the left on the front plate, SP1 is set to 400 ~mm .

C, 5, 5, means a setting of 1255 ~mm (hex “C” = decimal “12”). With this setting of the switches to the right on the front plate, SP2 is set to 1255 ~mm .

The setting of the setpoints determines the polarity of the analogue output function. See "LIMITS" - function switch 1.

Function switches 1-4

Switch 1: LIMITS / SETPOINTS

OFF: Output is in the range of 0....2000 mm (programmable). The analogue output signal is in the range of 150 to 2000 mm.

ON: Selectable polarity of the analogue output slope: Positive slope when SP1 < SP2 . SP1 defines the zero point (0 V or 4 mA) and the shortest distance. SP2 defines the final value (10 V or 20 mA) and the longest distance. Negative slope when SP2 < SP1 . SP1 defines the zero point (0 V or 4 mA) and the longest distance. SP2 defines the final value (10 V or 20 mA) and the shortest distance. See the following drawing.

SP1 < SP2: Positive slope

SP2 < SP1: Negative slope

Switch 2: HEX / BCD

OFF: Multiplexed data output, BCD coded.

ON: Multiplexed data output, HEX coded.

Switch 3: SENSITIVITY LOW / HIGH

OFF: Receive sensitivity and beam angle set to maximum.

ON: Receive sensitivity and beam angle set to minimum.

Switch 4: NC / NO

OFF: The switching outputs for setpoint 1 and setpoint 2 are normally open (NO).

ON: The switching outputs for setpoint 1 and setpoint 2 are normally closed (NC).

Serial Interface

Serial interface is fixed to data format: 9600, N, 8, 2. Special software is not needed. Communication is possible with every terminal program.

Hold / synchronizing input

By connecting Hold (HLD, active LO) to ground, the sensor is forced to stop operating and the last calculated distance is stored at the output. To avoid mutual interference from several sensors, these are simply

synchronized by interconnecting the HLD inputs. All synchronized sensors transmit at the same time.

Switching Outputs

The switching outputs are all PNP, 100mA and short-circuit protected.

SP1, SP2

Independently adjustable in steps of 1mm .

Switching hysteresis is fixed to approx. 1% .

Switching characteristic NO or NC can be selected.

ORA

If the analogue output has a positive slope, ORA indicates that no echo is received or the measured distance has exceeded the analogue range.

If the output slope is negative, ORA indicates that the distance is in the dead zone or below the analogue range.

URA

If the analogue output has a positive slope, URA indicates that the measured distance is in the dead zone or below the analogue range. If the output slope is negative, URA indicates that no echo is received or the distance has exceeded the analogue range.

Analogue Outputs

U Voltage output, 0 - 10V R_MIN = 1450 ohm

Current output, 4 - 20mA , R_MAX = 250 ohm

Multiplexed Digital Outputs

BCD or HEX. 4 data bits and 4 decade strobes NPN, open collector, 3+ V, 20mA , short-circuit protected.

Timing diagram of the multiplexed digital outputs - see following drawing.

Timing diagram of the multiplexed digital outputs

The actual output value is 1438.

SP1 < SP2: Pente positive

SP2 < SP1: Pente négative

To avoid interference from inductive voltage/ current peaks, separate the proximity switch power cables from any other power cables, e.g. motor, contactor or solenoid cables

Relief of cable strain

The cable should not be pulled

Protection of the sensing face

A proximity switch should not serve as mechanical stop

Switch mounted on mobile carrier

Any repetitive flexing of the cable should be avoided
