Frequently Asked Questions - UC EU 80-1 CARLO GAVAZZI

How to configure set points SP1 and SP2?

Use the two groups of three digital selectors on the front panel. Each group includes a hexadecimal selector (10²) and two decimal selectors (10¹, 10⁰). The resolution is in mm. For example, set 4,0,0 for SP1 to 400 mm and C,5,5 for SP2 to 1255 mm.

How to wire the module to the detection head UC80CND80FSM1?

Connect the head to terminals 3, 4, 5, 6 and 8 of the module following the wiring diagram provided in the manual. The connections are specific; refer to the manual for details.

What is the required supply voltage?

The module requires a voltage of 19 to 30 VDC with residual ripple ≤ 10%.

How to choose between NO and NC output?

Use selector 4 (NC/NO) on the front panel. OFF position = normally open (NO), ON position = normally closed (NC). The switching outputs SP1 and SP2 follow this setting.

What do the LEDs on the front panel mean?

SP1 and SP2 light up when their set points are activated. UB indicates power supply. OVER (PLUS) lights up if the measurement exceeds the programmed range. UNDER (MOINS) lights up if the measurement is below the programmed range.

How to synchronize multiple detectors?

To avoid mutual interference, connect the Hold inputs (HLD, terminal 10) of all modules together. All synchronized detectors will then emit simultaneously.

What is the measurement resolution?

The set point resolution is 1 mm, thanks to the programmable digital selectors. The operating distance is 800 to 8000 mm.

How to use the analog output (0-10V or 4-20mA)?

The analog output provides either a 0-10 V voltage (min load 1450 Ω) or a 4-20 mA current (max load 250 Ω). The slope (positive or negative) is defined by selector 1 and the set points SP1/SP2.

What to do in case of no echo?

If the analog slope is positive, the ORA output indicates an echo absence or range exceeded. Check the head alignment and target distance. In negative slope, URA signals this fault.

How to adjust the detector sensitivity?

Use selector 3 on the front panel. OFF position (high sensitivity) gives maximum reception and beam angle. ON position (low sensitivity) reduces sensitivity and angle.

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
