When the override potentiometer is turned to the right, the control outputs an analog voltage which is increased<br />
proportionally to the servo lag up to IOV max. The control is operating correctly if a voltage of<br />
IOV * O.lV can be measured at the test adaptor with the multimeter. If no voltage can be measured, switch<br />
off the main switch, disconnect the nominal value line from the servo amplifier and test for short-circuit. If the<br />
nominal value line is in order, connect the connector X8 to the LE again (leave the nominal value line disconnected),<br />
switch on the main switch and repeat the measurement with reference mark traverse. If an<br />
analog voltage can be measured now, the control is operating correctly. If no voltage can be measured,<br />
the analog output of the LE is probably defective.<br />
