To calibrate the product and bed pressure transducers:
1. The three-way valve (V-A) (Figure 4.12) handle shows the direction
of flow path. In Figure 4.12, direction of flow path is from oxygen
generator to pressure transducer. Close this manual three-way valve
(V-A), so that the flow path is from the atmosphere to the pressure
transducer.
2. Take out the plug, if any, from port A (Figure 4.12) and attach a manual
air pump having an accurate pressure gauge.
3. Press the ‘Calibrate 0 psig’ icon when the gauge on the manual air
pump reads 0 psig.
4. Manually pump the air so that the pressure reading on the gauge is
100 psig.
5. At this point, press the ‘Calibrate 100 psig’ icon on the calibration
screen to finish the calibration procedure.
6. Press and hold the “SET” button until it pops back out. This will save
the calibration.
7. Release pressure and check a few points in the range and ensure the
reading is close. If it is off, return to step 3.
8. Disconnect the manual air pump from the port A and put the plug, if
any, back to port A.
9. Open the manual three-way valve (V-A), so that the flow path is from
the oxygen generator to the pressure transducer as shown in Figure
4.12.
Press the ‘NEXT’ icon to navigate the calibration screen for Bed B and the oxygen
receiver pressure transducer.
4.10 CONTROL PANEL: INTERNAL COMPONENTS
The internal layout of the control panel mainly consists of the programmable logic
controller (PLC), oxygen concentration board (optional), HMI, circuit breakers,
transformers, and an alarm horn.
Programmable Logic Controller
The programmable logic controller contains the logic for the oxygen generator
operation.
