(11) Error Resetting (FUNCTION "B")
This function can reset error statues (FAIL lamp and FAIL contact output). An error status is
automatically reset at an instance when the causes of an error are removed but this function can
reset the error even if the causes are not removed. However, if the causes of the error still remain

For troubleshooting when errors occur, see Chapter 8.
(12) Reference Lamp Control Valve Calibration (FUNCTION "C")
This function determines the reference signal of the reference light-receiving element when the
amount of light from the lamp is controlled. Be sure to carry out this calibration after replacing the
lamp and then do a span calibration (calibration plate). For the lamp replacement procedure, see
Section 7.5.
The following is the procedure for this function.
(Example of display)
1. Select FUNCTION "C" in the <MAINT.> mode.
=> "L_CAL" is displayed.
2. Press the [ENT] key. The lamp voltage is

=> 1.4203 V
at 4.3 V.
The reference signal is displayed.
3. Wait for about 5 minutes or more until the
