Installation
Materials required
- Two M4 tamper-proof screws to mount each sensor.
- Cables to connect the control unit to the first sensor and the sensors to one another.
- Depending on the model, a data USB cable (product code X0000012) or an Ethernet cable (product code X0000013) to connect the control unit to the computer.
- Four M4 fixing screws for the slots of the ruggedized control unit.
- Two bus terminators (product code: 07000003) with resistance of 120 Ω.
- A screwdriver for tamper-proof screws to be used with the Hex pin security bit supplied in the control unit package.
- (only for SRE 100 Series sensors) If necessary, to protect the sensor and to prevent reflections from generating undesired alarms, one Metal protector kit (product code: 90202ZAA) per sensor. See the instructions supplied with the kit for installation instructions.
- Note: the Metal protector kit is particularly recommended if the sensor is installed on parts that are moving, vibrating or that are near vibrating parts.
Operating system required
- Microsoft Windows 10 or later
- Apple OS X 11.0 or later
- Install the ruggedized control unit
- Fix the control unit using four screws (not included) and connect to external equipment.
- Power-up the control unit using the power input connector XD1, and make all the other required electrical connections with external equipment (see Connector pin-outs).
- NOTICE: the SNS input “V+ (SNS)” and the GND input “V- (SNS)” are already connected inside the control unit.
- NOTICE: when powered, the system takes about 2 s (for Inxpect SRE 100 Series) and 20 s (for Inxpect SRE 200 Series) to start.During that period, the outputs and the diagnostic functions are deactivated, and the green sensor status LEDs of the connected sensors inside the control unitflash.
- NOTICE: make sure to avoid any EMC interference during the control unit installation.
- Install SRE 100 Series sensors
- Note: for installation with Metal protector kit (product code 90202ZAA), see the instructions supplied with
the kit.
Note: the usage of a thread-locking fluid on the threads of fasteners is suggested, especially when the sensor is installed on a moving or vibrating part of the machinery.
Note: if the sensor is installed on parts that vibrate and objects are present in the field of view, the sensor could generate undesired alarms.
- Position the sensor as indicated in the configuration report and fasten the bracket with two M4 tamper-proof screws.
- NOTICE: make sure the support does not inhibit machinery commands.
- Loosen the side screws to tilt the sensor.
- Tilt the sensor to the desired inclination.Note: a notch is equal to a 10° of inclination.
- Tighten the screws.
Install SRE 200 Series sensors
- Note: the usage of a thread-locking fluid on the threads of fasteners is suggested, especially when the sensor is installed on a moving or vibrating part of the machinery.
- Note: if no bracket is used for sensor installation, use tamper-proof screws and threadlocker.
- Position the sensor as indicated in the configuration report and fasten the bracket with two M4 tamper-proof screws directly onto the floor or another support.
- NOTICE: make sure the support does not inhibit machinery commands.
- With an Allen key, loosen the screw at the bottom to pan the sensor.
Note: to avoid damaging the bracket, loosen the screw completely before panning the sensor. - Pan the sensor until it reaches the desired position.
- Note: a notch is equal to a 10° of rotation.
- Tighten the screw
- Loosen the tamper-proof screws to tilt the sensor.
- Tilt the sensor to the desired inclination.
- Note: a notch is equal to a 10° of inclination. For a finer regulation of the sensor inclination with a 1° precision (see Inxpect SRE 200 Series Instruction manual).
- Tighten the screws.
- (optional and only for SRE 200 Series sensors) Mount 3-axis bracket
- The bracket that allows rotation around the z-axis (roll) is an accessory in the package. To mount it:
- Unscrew the screw at the bottom and remove the bracket with the sensor and the aligning ring.
- Attach the roll bracket to the base. Use the tamper-proof screw provided with the bracket.
- Mount the bracket with the sensor and the aligning ring. Use the tamper-proof screw provided with the bracket.
Connect the sensors to the ruggedized control unit
- Note: the total maximum length of the CAN bus line is 30 m (98.4 ft) for Inxpect SRE 100 Series and 80 m (262.5 ft) for Inxpect SRE 200 Series.
- Note: the DIP switch on the control unit is already in OFF position (bus terminator resistance excluded): there is no need to include it.
- Chain with control unit at the end of the chain and a sensor with termination connector
- Chain with control unit inside of the chain and two sensors with termination connector
Insert the bus terminators
- Insert two bus terminators (product code: 07000003) as follows
| If… | Then… |
| the control unit is at the end of the chain | insert one bus terminator into the free connector of the last sensor of the chain and the other one into the free connector of the ruggedized control unit. |
| the control unit is inside the chain | insert one bus terminator into the free connector of the two last sensors of the chain. |
