7. Use the UP arrow on the controller to advance the pre-filter pressure
reading on the screen to 6. Wait 15 seconds for the controller to
accept calibration information. Then push the DOWN arrow slowly
until it goes to the next lower number, waiting 15 seconds between
number changes. Continue with this procedure until you reach zero.
Wait 15 seconds then push the ENTER button. This enters the
calibration information into the menu and also advances you to the
post-filter pressure. Use the same procedure for post-filter, primary,
and final pressures. When you reach the permeate pressure, the
number that was changed to 6 is on the left of the word calibrate on
the second line. Calibrate the permeate pressure by using the same
procedure used on the other pressure transducers. When zero has
been reached, wait 15 seconds and then push ENTER several times
until you are out of the menu. Close all sample valves.
Open the inlet valve. Turn machine on to allow water to flow through
machine for 2 to 4 minutes to refill machine with water before starting.
Push the OFF button on the ECM-100 controller, then push the
HAND/AUTO button to AUTO position. The machine is now ready to
start up. Check to make sure all feedwater valves are open. Observe
the presence of pre-filter water pressure on the ECM-100 screen.
Energize the 23G pump. Then push the START button on the ECM
controller. Observe the pressures as the machine starts up. With
every thing running well, the calibration of the five pressure
transducers is completed.
NOTE:
The machine is designed to run in AUTO mode. Prior to restarting the
machine, confirm that the machine is in AUTO mode.
8. Press the ON key to turn machine on.
9. If unable to calibrate the ECM-100 as described above, see ECM-100
Troubleshooting (Section 7.2).
8.7 Flow Calibration Procedure
8.7.1 Calculating Permeate Flow Rate
1. Check and record the ECM-100 permeate flow while the
machine is running.
2. Turn the machine OFF.
3. Install a 1-inch I.D. flexible hose [at least 4 feet (1.2 m) in
length] to the CIP permeate fitting. The CIP fitting requires a 1-
inch MPT threaded fitting.
4. Open the permeate CIP valve.
