Page 6: Care Of The Probe
Keep system components clean and treat the probe as a precision tool. Patents Features of TRS2 non-contact broken tool detection system, and other similar Renishaw products, are the subject of one or more of the following patents and/or patent applications:... -
Page 7: Safety
Information to the equipment installer All Renishaw equipment is designed to comply with the relevant UK, EU and FCC regulatory requirements. It is the responsibility of the equipment installer to ensure that the following guidelines are adhered to, in order for the product to function in accordance with these regulations: •... - Page 8 • Prevent the laser beam from straying outside of the immediate work area. A beam terminator is supplied with the TRS2, which may be fixed to the outside of the machine window for this purpose. CAUTION – LASER SAFETY The laser used in the Renishaw TRS2 non-contact broken tool detection system emits visible red light at a wavelength of 670 nm and has a power output of less than 1 mW.

Page 9: Trs2 Basics
A tool that is rotating at a speed of 5000 r/min, 1000 r/min or 200 r/min is moved into the laser beam. The output of the TRS2 is activated and the output changes when the tool is detected by the receiver. -
Page 10: Bar Graph Display
Bar graph display The bar graph display on the front of the TRS2 unit indicates the level of light falling on the receiver. The minimum requirement for effective tool detection is that the amber LED and at least one green LED must be illuminated. -

Page 13: Trs2 Specification
Note 1 Each TRS2 unit is tested with a Ø0.5 mm (0.02 in), blue finish, HSS jobber drill at a range of 350 mm (13.8 in). Test conditions: dry tool, spinning at 5000 r/min, which must be detected by the TRS2 within 1 second. - Page 14 TRS2 installation guide This page is intentionally left blank.
-
Page 15: System Installation
Guidelines When installing the TRS2, keep the following points in mind: • The tool must be able to move in the Z axis relative to the TRS2 system, so that tools of different lengths can be checked; • the closer the TRS2 is to the tool, the greater the reflected light level, so small diameter tools or those with a dark finish are more easily detected;... -
Page 16: Mounting The Trs2 Unit
For M4 mounting screws, tighten to 4.0 Nm (2.90 lbf. ft) using a 3 mm AF hex driver. When the TRS2 unit is rear mounted, fit the M6 locking screw and washer (as shown in the figure below) and tighten to 14.0 Nm (10.30 lbf. ft) using a 5 mm AF hex driver. -
Page 17: Air Supply
If it is necessary to switch off the air supply, ensure that the coolant supply is switched off first. The air supply to the TRS2 system must conform to BS ISO 8573-1: air quality of class 1.7.2 and be moisture-free. If the air quality cannot be guaranteed, an optional air filtration system is available from Renishaw (see Chapter 6, “Parts list”). -
Page 18: Connecting And Purging The Air Supply
Push the free end of the air supply pipe through the air pipe spring conduit. Remove the tape from the end of the air pipe. Before connecting the pipe to the inlet of the TRS2 unit, briefly switch on the air supply to clear out any debris from the pipe. -
Page 19: Air Blast Kit
Mount the air blast unit on a rigid surface; • use an air feed controlled with a solenoid valve and M-code; • DO NOT take the air feed controlled from the TRS2 air filter kit, use a separate supply; • set the air pressure to 4 bar; •... -
Page 20: Electrical Connections
Power supply The TRS2 can draw its power from the CNC machine’s 12 V to 24 V nominal dc supply. Its input voltage range is 11 Vdc to 30 Vdc maximum and it presents a typical load of up to 65 mA at 12 Vdc and up to 43 mA at 24 Vdc. -
Page 21: Setting Up The Trs2 System
Setting up the TRS2 system Preparation To set the operating range of the TRS2 you will need to change the settings of the receiver focus screw and laser focus screw. If these screws cannot be accessed when the TRS2 unit is mounted in the machine, range setting can be performed off the machine. - Page 22 Receiver focus screw Laser focus (not available on TRS2-S) screw Using a pin spanner (see the figure below), loosen the locking ring of the laser focus screw by 1 to 2 turns (turning counter-clockwise) until it is fully slackened.
-
Page 23: Spindle Speed Selection
Spindle speed selection For a tool to be detected by the TRS2 system, it must be rotating at a fixed speed of 5000 r/min, 1000 r/min or 200 r/min. The required spindle speed must be selected in the macro software. -
Page 24: Using The Signal Monitor Function
The signal monitor function is available only on the version of TRS2 that is fitted with a connector. If the bar graph on the front of the TRS2 is obscured, for example, blocked by a shutter, the signal monitor function can then be used to monitor the reflected light signal level. Do this as follows: Connect the pink (+) and blue (–) wires to a digital voltmeter (DVM). -
Page 25: Maintenance
About cleaning Cleaning may be required if the air to the TRS2 becomes contaminated or if the system is left with the air off when coolant is present. Excessive contamination of the transmitter’s air cap will block the laser beam and prevent the TRS2 from functioning. -
Page 26: Cleaning The System
TRS2 installation guide Cleaning the system CAUTION: Before removing the air cap, switch off electrical power to avoid exposure to the laser beam. Make a note of the air supply pressure, then switch off the air supply and power supply. -
Page 27: Replacing The Receiver Lens
11. Switch on the air supply and set the pressure to the value noted in step 1. 12. Switch on the power supply. 13. Now check that the laser beam displays a good spot (for more information, see “Air supply” on page 3.3 of Chapter 3, “System installation”). -
Page 28: Fitting A Sapphire Glass Window
TRS2 installation guide Fitting a sapphire glass window If the TRS2 receiver lens is likely to become scratched due to bombardment by swarf, it can be protected by a hard sapphire glass window (for more information, see Chapter 6, “Parts list”). -
Page 29: Draining The Liquid
Draining the liquid Drain the liquid that has accumulated in the filter bowls as follows: Make a note of the air supply pressure, then switch off the air supply. A quantity of liquid will drain from the bowls. Switch on the air supply and set the pressure to the value noted in step 1. Repeat steps 1 and 2 until the bowls are empty. -
Page 30: Replacing Other Service Kit Components
Switch on the air supply and set the pressure to the value noted in step 1. NOTE: Items shown within dotted boxes A and B are included in the air filter service kit obtainable from Renishaw (for more information, see Chapter 6, “Parts list”). -
Page 31: Fault-Finding
There is no laser beam. Check the Tx aperture for blockage. Check the power connection. The TRS2 fails to detect all good tools. Check that the spindle speed is set to 5000 r/min, 1000 r/min or 200 r/min with no spindle override set. - Page 32 TRS2 installation guide Symptom Action The TRS2 fails to detect all good tools Check the tool position in the laser beam at the (continued). checking point. Check that the laser focus screw is set correctly. Check that the receiver focus screw is set correctly.
