7.1.2 Leak Check
Refer to Section 5.6 for the leak check procedure.
7.1.3 Bypass Pump Diagnostic Procedures
The bypass pump is capable of maintaining a total bypass flowrate of ~2.2 lpm. If flow checks
indicate a fall off in bypass flow, the pump may need servicing. Check the pump, inlet fittings,
and analyzer for leaks first. If other causes have been eliminated, rebuild the pump.
7.1.4 Electrical Fault Isolation
115 VAC is supplied to:
the bypass pump
the +5 volt and +24 volt switcher supplies
the input power to the converter temperature controller
Use Figure 6 to check the 115 VAC supply voltage to each of these components.
The converter temperature is controlled by the FUJI controller located on the Pump Module front
panel. The controller cycles power to the external converter, thereby maintaining the temperature
at 315
O
C, using the solid state relay.
7.2 Setting the Converter Temperature
A front panel-mounted programmable controller maintains the temperature of the remote
molybdenum converter. By pressing the PV/SV button in the lower left corner of the controller,
you can see the Present Value (actual temperature) or the Set Value (temperature set point). The
temperature and PID control parameters have been set at the factory and no further adjustment
should be necessary. Should you need to adjust the temperature, follow these steps:
1. Select SV with the PV/SV button,
2. Press the "up-arrow" under the digit you want to change,
3. (the digit will flash),
4. Press the "up-arrow" under the digit or the "down-arrow" at the left to scroll
the digit to the desired value,
5. Repeat for the other two digits,
6. Press the ENTER button.
7. Select PV with the PV/SV button to observe the actual temperature.
7.2.1 Temperature Controller Setup
The FUJI temperature controller has been programmed at the factory and should not need to be
altered under normal usage.
