5.3.2 Function and application
The product is a non-contact analog position sensor. The sensor provides an output signal proportional to the cylinder stroke.
The magnet integrated in the cylinder piston generates a magnetic field. This magnetic field acts on the sensor elements that are arranged along the longitudinal axis of the distance measuring sensor. A special evaluation of the sensor signals determines the current position of the cylinder piston. For further information, see the Technical Information (MNR R412018764).
The measurement range is set to the entire measuring length of the respective sensor at the factory. The zero point and final value of the measurement range can be adjusted to the stroke to be measured via a teach-in button. The product can be used specifically for measuring a section of the entire cylinder stroke (partial stroke sensor).
If the magnetic piston leaves the sensor’s measurement range, the output signal is frozen at the most recently measured value until the magnetic piston again enters the measurement range.
As analog output, a voltage and current signal is made available (see g Table 2 and g Table 3).
An in-range display supports the assembly of the distance measuring sensor: An LED lights up when the magnetic piston is within the measurement range.

Assembly and installation

Before you start with the installation: Familiarize yourself with the basic specifications for assembly as early as possible in advance: see sections g 6.1. Planning and g 6.2. Preparation.
6.1 Planning

Accessory parts
Depending on the chosen configuration and the application, additional components are required to integrate the product into the system and the system’s control.

6.2 Preparation
6.2.1 Notes

• Do not carry out any work on the system during preparation (accident prevention).

6.2.2 Unpacking and checking the product

1. Unpacking the product.
2. Check the material number to see if the product matches your order. The material number can be found on the housing of the product.
3. Check the product for transport and storage damage. Do not install a damaged product. Return damaged products together with the delivery documents (address: see back cover).
4. Prepare required accessories, materials, and tools.

6.2.3 Implementing safety measures Procedure
All work has to be prepared as follows:

1. Close off dangerous areas (accident prevention).
2. Make sure the system or system part is not under pressure or voltage (accident prevention).
3. Protect the system against being restarted (accident prevention).
4. Allow the product and adjacent system parts to cool down (accident prevention).
5. Wear protective clothing (accident prevention).

6.3 Installation
6.3.1 Assembling the distance measuring sensor

1. Sensor
2. T-slot
3. Detailed view: assembly position

Procedure

1. Insert the sensor (1) into the T-slot (2) from above using a light swivel motion (3) and fix it with the hexagon screwdriver.

2. Connect the sensor to a suitable power supply (see section g 13. Technical data and the following figures).
   The sensor has both an analog voltage output (0 … 10 V) and a current output (4 … 20 mA).
   The sensor only activates the output that is switched.
   During assembly, the axial orientation of the sensor can be supported by the range display. The LED flashes or lights up when the magnetic piston is in the distance measuring sensor’s permissible measurement range.

3. Move the sensor in an axial direction until it records the entire stroke range to be measured.

4. Fix the sensor in the adjusted position by tightening the two mounting screws equally.
   Tightening torque MA = 0.25 + 0.1 Nm

5. Check whether the sensor records the stroke range to be measured: In-range display (LED) must light up.

6. If the in-range display does not light up: Re-align the axial orientation of the sensor.
   INFO: An exact axial alignment is a prerequisite for all further steps.

 Commissioning

Follow the steps below to carry out commissioning.
7.1 Basic requirements
Personnel qualifications Commissioning only by qualified personnel (see section g 2.5. Personnel qualifications).

Limits

• Comply with the limits (accident prevention, material protection). Limits: see section g 13. Technical data.

7.2 Notes on safety
To eliminate risks during commissioning, observe the notes on safety: see section g 2.6.1. Notes on safety.
7.3 Preparation General requirements

• Ensure that the system is in a defined state before switching it on (danger of accidents). If the system is not in a defined state, switching on the pneumatics can lead to uncontrolled movements of the actuators.
• Only commission the product after it has been completely assembled as well as correctly connected, and after it has been properly tested.

7.4 Step-by-step commissioning
If you have carried out and completed all preparation work, you can commission the system.
Optional: Adjusting the measurement range (see section g 7.4.1. Adjusting the measurement range).
7.4.1 Adjusting the measurement range

• ****The maximum permissible measurement range is set as standard. The measurement range is only adjusted via the teaching-in process.
• If the magnetic piston is outside of the measurement range during the adjustment process, this is indicated by an increased flashing frequency and the teach-in process is aborted.
• A teach-in process that is not completed successfully is aborted after 90 s (timeout). The most recently set measurement range is maintained.

Adjusting the measurement range as described below is optional.

Procedure

1. Move the magnetic piston to the position for the zero point.
2. Check if LED lights up (magnetic piston is in the measurement range).
3. Press and hold the teach-in button until the LED flashes (t = 3 s).
4. To save the zero point: release the button. (Flashing LED indicates that the endpoint still has to be set.)
5. Move the magnetic piston to the position for the endpoint.
6. Briefly press and hold the teach-in button (t = 1 s).
7. To save the endpoint: release the button.
   ⇒If the LED lights up, measurement range adjustment is completed.
