In addition there is a thermocouple amplifier for the Moly converter.

Thermistor Temperature Amplifier Adjustments

If the temperature readouts are in error:

1. Locate the Box temp thermistor on the board and place a calibrated thermometer near the

thermistor.

2. Select the BOX TEMP - TEST function on the front panel.

3. Adjust R34 until the front panel readout matches the thermometer readout. This will

cause all of the readouts to accurately measure their respective temperatures.

Molybdenum Converter Thermocouple Amplifier Adjustments

The molybdenum converter temperature is sensed by a thermocouple. The cold junction

compensation and signal conditioning is done on the Temp/Status board.

The buffer amplifier from the thermocouple amplifier to the CPU for the Moly temperature has a

gain adjustment. The voltage times 100 at pins 8-9 of U1 is the Moly temperature in degrees C.

For example 3.15 VDC at pin 9 of U1 is 315o C. The CPU is programmed to always drive the

temp to 315° C, so the voltage at U1 must be used as the absolute reference as to the correct

temperature. The temperature will vary ± 3 degrees due to the operation of the temperature

control loop in the CPU.

The R6 pot on the Status/Temp board can adjust the temperature. To adjust the molybdenum

converter temperature:

1. Select the CONV TEMP - TEST function on the front panel.

2. Wait until the converter is up to temperature, usually 30-45 min after a cold start.

3. Adjust R6 until the voltage at pin 8-9 of U1 is 3.15 VDC. The CONV TEMP - TEST

function will then read 315° C.

4. Recheck the temperature 15 min later and re-adjust if necessary.

9.3.4.2 Display Brownout

During low AC line conditions the display can lock up due to insufficient voltage. When low

line conditions are approaching, this circuit senses the condition by monitoring the un-regulated

+5 VDC in the Power Supply Module. If brownout conditions are met, the DISP_BROWNOUT

line is asserted and the CPU sends a hardware RESET command to the display and sends a

BRNOUT RESET pulse back to U4. Brownout conditions will be noticed by the display flashing

every 8 seconds.
