The RO machine is controlled using the Operation Screen. The FILL button energizes the
inlet solenoid valve allowing the RO machine to fill water. The machine will run for ten
(10) minutes filling the machine. This needs to be done before the RO machine can oper-
ate. Once the machine has been filled the RO, CIP, and PURGE buttons will operate.
The RO button controls the RO machine when it is in Run Mode. If the RO machine is
not in Run Mode, the RO button switches the RO machine from its current condition to
Run Mode. In the AUTO position the RO machine will shut down without going into
Permeate Purge.
The CIP button controls the RO machine when it is in CIP Mode. If the machine is not in
CIP Mode, pressing this button (CIP) will switch the machine from its current mode to CIP
Mode. See the Operation and Maintenance Manual (P/N 1161875) for details on running
CIP. If the machine is in CIP Mode, pressing the button shuts the RO machine down.
The PURGE Button controls the Permeate Purge Cycle of the RO machine. If the RO
machine is not in Purge Mode, pressing this button will switch the RO machine to
Permeate Purge for ten (10) minutes and then turn the machine OFF. If the RO machine
is in Purge Mode, pressing this button will shut down the machine.
The AUTO/HAND Button, located under the Purge Button, controls Permeate Purge oper-
ation. In the HAND position the RO machine will only go into Permeate Purge by man-
ually pressing the Purge Button. In the AUTO position, the RO machine will go into
Permeate Purge when the RO machine gets a signal from an external device, like a level
switch.
The ALARM Button takes the user to the ALARM HISTORY Screen, described later
(Section 2.3).
The INFORMATION Button takes the user to the MACHINE STATUS Screen, described
later (Section 2.4).
The UTILITIES Button takes the user to the UTILITIES Screen, described later
(Section 2.5).
The ALARM RESET Button is used to clear any alarm conditions, such as low inlet pres-
sure, high permeate pressure, or motor overload. This button needs to be pressed before
the RO machine will operate. The ALARM RESET Button on the Control Enclosure may
need to be pressed as well.
The SYSTEM message, located under the Control Buttons, shows the user the current sta-
tus of the machine. During shutdown, this message will display reason for shutdown.
