OMP40-2 work probe: A spindle-mounted wireless probe that communicates with an optical interface. 2. Work probe stylus: The part of the work probe that touches parts during measurement. 3. Tool probe stylus: The part of the tool probe that tools touch during measurement. Tools touch the top and side of the stylus when the probe measures tool length and diameter. 4. OTS tool probe: The OTS is a battery-powered, wireless probe. 5. OMI-2H Optical Machine Interface:The wireless interface for the OMP40-2 work probe. The OMI-2H uses infrared light to communicate with the CNC control and switch the probe on or off. 6. OMI cable: This cable connects the OMI to the CNC control. Work probes for Wireless Intuitive Probe System (WIPS) do not work in the wired probe systems (VQCPS). The work probes can be differentiated by: 1. The VQCPS work probe (P/N ) has a square Haas logo. 2. The WIPS work probe (P/N ) has a round Haas logo. For installation instructions for both the work probe and tool probe refer to: Wireless Intuitive Probe System (WIPS) - Installation Powering on the Work Probe and Tool Probe: Probe Operation: Power on the Work Probe Power on the Tool Probe Copyright 2018 by Haas Automation, Inc.

3 Probe Operation: Power on the Work Probe Power on the Tool Probe The LEDs on the work probe flash green when the probe is powered on and ready for use. When the probe stylus is touched, a beep sound is made by the CNC control. The LEDs on the work probe flash red each time the stylus is touched. When the stylus on the tool probe is touched, the CNC control makes a "beep" sound. The tool probe does not have any LEDs. Troubleshooting Symptoms: Symptom Possible Cause Corrective Action Alarm 1101 PROBE STARTUP FAILURE. Alarm 1092 PROBE OPEN. Alarm 1093 PROBE FAIL. Incorrect measurements. The probe does not give repeatable location results. Bad batteries. The settings in the work probe are not correct. Interference from the work lights. The settings in the work probe are not correct. The surface of the part was not found. The probe is not calibrated. The probe stylus is loose. The probe stylus is not concentric to the spindle centerline (runout). The WIPS programs or macro variables are corrupted. Replace the batteries. Correct the settings. Adjust the work lights. Correct the settings. Edit the program. Calibrate the probe. Check the probe stylus. Adjust the probe stylus to eliminate runout. Load the latest Renishaw macro programs. Make sure to overwrite the current macro programs. Batteries Corrective Action: Battery replacement is always the first step in probe troubleshooting. Replace both batteries at the same time. Test the batteries before you install them. The batteries in the probes have a life span of about (8) months, and must be replaced regularly. If the batteries are low, the work probe's green and blue LEDs may flash. If the batteries are completely dead, the red LED may constantly be on. Do not rely on a multimeter for testing the batteries. The lithium batteries in the probe may read 3.6 Volts from a multimeter, even though they are low. Write the date on newly installed batteries for future reference. Note: Do not touch the stylus during battery replacement. If the stylus is touched, the probe may power on in the setting mode. Settings can be accidentally changed in this mode.

4 Interference Corrective Action: Turn the work lights off to begin troubleshooting. Make sure the work lights inside the machine are not aimed at the probe or the OMI-2H. Bright lights can interfere with the work probe. Make sure no bright lights are aimed at the machine. Surface Not Found Corrective Action: Edit the program to start the probe closer to the part.

5 Calibration Corrective Action: The probes need to be calibrated any time a stylus has been replaced, the tool probe has been moved, or if the CNC control generates alarms during probe routines. Follow the procedure to calibrate the tool probe and the work probe. Refer to: CHC: Wireless Intuitive Probe System (WIPS) - Calibration. NGC: Next Generation Control - Probe Calibration (VPS) The probes must be calibrated in this order: 1. Tool probe 2. Work probe length 3. Work probe diameter OMP 40-2 Work Probe Settings Probe Settings Basics The probe settings are in these (4) groups: 1. Switch-Off Method 2. Enhanced Trigger Filter 3. Optical Transmission Method/Probe Identification 4. Optical Power The sequence that probe flashes tells you the current probe settings. Note: The LEDs flash in different colors and different lengths of time. The sequence that the LED flashes tells you the probe settings. The LEDs flashes a short or a long time. In the tables that follow, a small colored circle shows that the LED flashes a short time. A rectangle shows that the LED flashes a long time. To see what the current probe settings are, do the following: Remove the batteries from the probe for a minimum of 5 seconds. Install the batteries. Important: Do not touch the probe stylus after re-inserting batteries - this is how probe settings are changed. Only touch it later if necessary to change the settings. After you replace the batteries, the probe LED flashes in a specific sequence. Look at the probe LEDs. Record the sequence that the LED flashes. Refer to Renishaw - Probe - OMP Settings for the meaning of the sequence. If you would like to change the probe settings, do the following: Copyright 2018 by Haas Automation, Inc.
