7.1.3 501Y Bypass Pump Diagnostic Procedures
The 501Y bypass pump is capable of maintaining a total bypass flow rate 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
Refer to Figure 7 to check the 115 VAC supply voltage to each of these
components.
The converter temperature is controlled by the FUJI controller located on the
501Y 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 external 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 (proportional, integral
and derivative) 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 (the digit will
flash),
3. Press the "up-arrow" under the digit or the "down-arrow" at the left to
scroll the digit to the desired value.
4. Repeat for the other two digits.
5. Press the ENTER button.
6. 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.
