1.
Insure Power Supply Module is securely connected to the Source Cup
Assembly. Turn power switch SW1 ON.
2.
The main menu will default after boot up screens.
3.
If the VaporGuard® is already on, insure that it is in idle mode (front switch red
LED is on continuously). Alarms may be present which will result in a flashing
red LED on the front switch, but the unit will still be in idle mode.
4.
Remove the probe from the bubbler. Then remove the 9 pin (DB9) temperature
probe connection from the Source Cup Assembly. The display will read 119.9ºC
and a “RTD Open” and “Probe Not Installed” alarms will result.
5.
Install the calibration PCA at connector P7A to the temperature probe connection
J7. The screen will automatically update to the “POT CONFIG?” screen. Select
the green check mark “√” to get to the “TEMP POT CONFIG?” screen. Select
the green check mark “√” again to adjust the individual potentiometers shown in
figure 7-2.
NOTE:
The Stainless Steel Level Sense Calibration screen is also enabled when the
Temperature Calibration PCA is installed. Do not adjust the SS POT
CONFIG parameters as it is not required.
6.
Read the display to verify a temperature of 1.3ºC. If the display reads
1.3ºC±0.2ºC, then skip to step 8.
7.
If the display does not read 1.3ºC to within the specified tolerance, adjust the
offset potentiometer until the display reads within tolerances. Use the up or
down arrow to change the potentiometer parameter. The offset potentiometer is
designated by the “O” in the top row on the left side of the screen example
shown below.
8.
The temperature reading is on the second row, right side. The corresponding
analog signal is also displayed on the second row (units of volts DC). It is used
for troubleshooting purposes only. Use the left or right arrow to move the cursor
to the next potentiometer parameter.
NOTE:
The Temperature Calibrator PCA may require validation once a year. This
