Polymer Electric Product overview Product overview Sensor (Ultrasonic Transducer) The special cable between the ultrasonic transducer and the M8 plug has a fixed length of 1.5 m and may not be lengthened or shortened. Should the 1.5 m not be sufficient, the cable length can be doubled using the optional extension cable (1005903).

Polymer Electric Operation Operating Mode Window The operating mode Window can be exclusively selected via the parameter assign- ment software (optional). SP1: > 1 cm SP2: > (SP1 + 1 cm) In contrast to operating mode 2 ranges, here the detection field that is sensor- proximal will not be visible.
Polymer Electric Operation USi-IP The distances determined by the sensor are indicated as analog current values between 4.8 and 20 mA on output “OUT°1.1” . The linear progression results from the even sub-division of the total measurement distance up to SP2. In the default set- ting, this is 0.08 mA per centimetre.

Polymer Electric Installation Installation The installation includes three individual installation steps: 1. Mounting the sensor (ultrasonic transducer) 2. Mounting the Evaluation Unit 3. Wiring the unit cable Mounting the Sensor (Ultrasonic Transducer) The sensors can be mounted in any position. If the sensors are supposed to be mounted in quiet workplaces or in areas where there are hearing-sensitive animals, the interfering sonification must be considered.
Repairs are not possible. Alternative: Enclosure set (optional) Instead of using your own brackets you can also use one of the Mayser enclosure sets. See Chapter Accessories for a small selection. The installation steps are the same as described above.
Disconnect all devices and live parts in the immediate environment of the power supply and protect them against being switched on again (see relevant Operating Instructions). Check whether all devices and parts are disconnected from the power supply. Lead colour Signal USi-PP USi-IP USi-UP Brown DC 15 to 30 V Blue max.

Polymer Electric Commissioning Commissioning The Evaluation Unit expects that at least one sensor (ultrasonic transducer) is con- nected. If only one sensor (ultrasonic transducer) is used, then this must be con- nected to “Sensor 1” . 1. Connect the sensor (ultrasonic transducer) and the unit cable with the Evaluati- on Unit.

Polymer Electric Adjust settings Adjust Settings The following settings can be changed with the “Teach In” button: 1. Teach in environment 2. Adjusting switch points 3. Logoff/logon sensor 4. Restore factory settings Teach In: Teach in Environment The actual function of “Teach In” is to teach in the environment within the detection field.
Page 24
Polymer Electric Adjust settings The switch points can be set between 1 and 250 cm. The “Set Switch Points” function is always available with a USi that is ready for operation. The preset standard settings for all sensors are switch points SP1 = 1 cm and SP2 = 200 cm.
Polymer Electric Adjust settings 8. Place the reference object at the desired distance in the detection field. If the USi recognises the reference object, the green LED “Power” changes from quick flashing (5 Hz) to being continuously lit. 9. Press the “Teach In” button (> 0.5 s), and the USi overwrites the previous switch point SP1 with the determined distance to the reference object.
Polymer Electric Adjust settings 6. Now press the “Teach In” button > 0.5 s. The USi signalises that Sensor 2 is now logged on by the continuously lit yellow LEDs “OUT” for 1 s. This is how to logoff Sensor 2: 1.
Page 27
Polymer Electric Adjust settings The green LED “Power” flashes for 5 s slowly (1 Hz), then the yellow LEDs “OUT” are lit continuously for 2 s. Subsequently, the green LED “Power” flashes slowly (1 Hz). 4. Now release the “Teach In” button. Now all the LEDs are lit alternately from the top to the bottom in the manner of a chaser light.
