VRO Encoder Readout Troubleshooting Guide
VRO Readout Troubleshooting
First - always read the Users Manual.
| Symptom | Possible Cause |
|---|---|
| The carriage is moving but the Readout is not changing. | Check the plugs to ensure they are connected properly. |
| Check for any loose wires. | |
| The reading head may be too far from the encoder. Make sure they are in close proximity but not touching. | |
| Readout is showing the wrong unit of measure. | Check to make sure you are using the right encoder settings. Reset the scale. (All the encoders available from Velmex are programmed into the VRO Readout.). |
| The display is blank but light is flashing. | VRO has been put in sleep mode. To exit sleep press "U" button, or send any character in the Serial port. |
| Status light flashing rapidly and display shows partial information or odd characters. | Power is intermittent or was interrupted. Check power input connector and cycle power. |
| Status light pulsating and display shows ">5 INPUT VOLTS !" | Power in is greater than 5.4 volts, disconnect power adapter and check the voltage. |
| Power in is less than 4.6 volts, check power adapter voltage, and encoder load. | |
| Status light pulsating and display shows "Enc Input Fail !" | Poor encoder connection, electrical interference, or count exceeding 1.6 MHz. command. |
| It will not let me make setting changes. Displays "Not Settable". | VRO needs to be cleared (set to defaults) and the process restarted. |
