Resetting Factory Defaults
In some cases, it may be advantageous to reset the readout factory default settings.
Doing this will cause all parameters to revert to the state they were in when the
readout left the factory. Once accomplished, it may be necessary to re-establish
certain parameters as needed for proper EDM functions.
To reset factory default settings:
1. Turn power off to the readout, wait 5 seconds and turn power on.
2. While the power off message is being displayed, press and hold the M key for
two seconds.
3. Press the 3 key.
4. Turn power off to your readout, wait 5 seconds and turn power on again.
Factory default settings have now been reset.
Other Error Messages
The readout includes built-in test and error-checking circuitry. This circuitry identi-
fies errors that occur, and reports the problem to the operator. Errors are reported
by scrolling messages in the X-axis display.
Loss of power is indicated by the "POWER WAS OFF" message. Loss of power
means that power to the readout has been interrupted. Since power to the encoders
has also been interrupted, positioning information may no longer be accurate. Press
the
C key to clear the error message. All display measurements will be zeroed.
Refer to page 4 for information about position recovery.
Counting errors are indicated by the "SCALE MISCOUNT" message, telling you
in which axis the miscount occurred. Counting errors result from distorted electrical
signals from a scale. These signals can be a result of an scale malfunction,
mis-alignment, mounting problems, or electrical interference. Press the
C key
to clear the error message. The axis display (for both absolute and incremental mea-
surements) will be zeroed. Follow these steps to determine if your difficulties are
associated with the readout or with the scale.
• Ensure that the linear scale connectors are correctly seated.
• Swap linear scale cables at the readout to see if the problem still appears in
the same display.
