ESPAÑOL Installation DEUTSCH Page 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. DANSK

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. ITALIANO CONTENTS ENGLISH Ultrasonic Evaluation Unit for Sensor Head Type UC EU 80-1

3. Programming the unit and the sensor head UC80CND80FSM1

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

ENGLISH Front Panel This chapter gives a brief description of the switches and the LED’s, which are all placed on the front panel. ITALIANO DANSK F 0 12

SP2 OVER UNDER RANGE ON when Setpoint 1 is active. ON when Setpoint 2 is active. ON when power is applied. ON when the measurement exceeds the programmed range. ON when the measurement is below the programmed range. UNDER 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. = hundreds switch

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. FRANÇAIS The setting of the setpoints determines the polarity of the analogue output function. See “LIMITS” - function switch 1. Function switches 1-4 ESPAÑOL

Switch 4, NC / NO Switch 3, SENSITIVITY LOW / HIGH Switch 2, HEX / BCD Switch 1, LIMITS / SETPOINTS 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: DEUTSCH

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

Switching Outputs ENGLISH synchronized by interconnecting the HLD inputs. All synchronized sensors transmit at the same time. 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. ESPAÑOL SP1, SP2 Independently adjustable in steps of 1 mm. Switching hysteresis is fixed to approx. 1%. Switching characteristic NO or NC can be selected. FRANÇAIS DEUTSCH The switching outputs are all PNP, 100 mA and short-circuit protected.
