1. MFC. Use this function to set the MFC setpoint. Press the ENTER key, set the required setpoint (e.g. 100
l/hr), and press the ENTER key again. The actual flow is shown at the top of the screen. An “*” is shown
when the MFC has been activated. If the flow is 0.0 l/h, then the MFC is switched off.
2. Ozone Generator. Use this function to test the ozone generator. To change the state of the device, press
the ENTER key, set the device to ON/OFF, and press the ENTER key again. If the device is on, it will be
marked with an “*”. As a safety feature, when the Ozone Generator is switched on, a Pressure Test
procedure is executed automatically to detect any gas leakage in the system. If this test fails then the
Ozone Generator will not be switched on. See Section 8.1.1.1 Pressure Test and Section 8.3.4.6
Pressure/Flow Test Program for details on Pressure Test.
Ozone will be generated when the ozone generator is turned on.
3. Acid Pump. Use this function to test the Acid Pump. To turn the pump on, press the ENTER key, and
select ON. Press ENTER again, input the number of pulses (½ revolutions), press ENTER and the pump
will run. When the Acid Valve is activated, the maximum allowable number of pulses, which can be
programmed, is 20. When the pump is running the actual (outside brackets) and programmed pulse time
(inside brackets) is shown. The pump will stop when the required number of pulses is complete, or to
manually stop the pump, press ENTER, select OFF, and press ENTER again.
4. Acid Valve. Use this function to test the Acid Valve. To change the state of the device, press the ENTER
key, set the device to ON/OFF, and press the ENTER key again. If the device is on, it will be marked with
an “*”. When Acid Pump is run while Acid Valve is activated, due to system interlock to prevent reactor
flooding, “REACTOR PURGE” function below may be required for successive Acid Pump testing.
5. Base Pump. Use this function to test the Base Pump. To turn the pump on, press the ENTER key, and
select ON. Press the ENTER key again, input the number of pulses (½ revolutions), press the ENTER key
and the pump will run. The maximum allowable number of pulses, which can be programmed, is 20.
When the pump is running the actual (outside brackets) and programmed pulse time (inside brackets) is
shown. The pump will stop when the required number of pulses is complete, or to manually stop the
pump, press the ENTER key, select OFF, and press the ENTER key again. Due to system interlock to
prevent reactor flooding, “REACTOR PURGE” function below may be required for successive testing.
6. Base Valve. Use this function to test the Base Valve. To change the state of the device, press the
ENTER key, set the device to ON/OFF, and press the ENTER key again. If the device is on, it will be
marked with an “*”. When Acid Pump is run while Base Valve is activated, due to system interlock to
prevent reactor flooding, “REACTOR PURGE” function below may be required for successive Acid Pump
testing.
7. pH Adjust Valve (if configured in the system). Use this function to test the pH Adjust Valve. To change
the state of the device, press the ENTER key, set the device to ON/OFF, and press the ENTER key
again. If the device is on, it will be marked with an “*”.
8. Sample Valve. Use this function to test the Sample Valve (ARS-Automatic Range Selection Valve). The
valve has three positions, SEN1 (Sample Pump to Bypass), SEN2 (Sample Pump to Reactor), and SEN3
(TIC Acid/TC Base to Reactor). To position the valve in different positions, press the ENTER key, select
the required position, and press the ENTER key again. While the valve is moving the sensor, the system
marks this menu item with an “*”.
