23G-Series RO System
3024270 Rev G 78 14Oct13
5.16 Permeate Divert
Factory-installed valves divert the RO permeate to drain for a preset
period of time upon machine start-up or when the RO permeate exceeds a
preset conductivity level. This optional feature ensures good quality water
flows to storage or to points of use. A start-up divert timer setting in the
timer presets menu of the ECM-100 controls the duration of permeate
divert each time the machine starts up. A high conductivity level is set in
the Alarm Limits menu so that permeate is diverted should the conductivity
exceed that level. The divert mode can be disabled if desired by setting
the start-up permeate divert timer to zero and selecting WARNING ONLY
or SHUT DOWN from the permeate high conductivity alarm function menu
(10).
5.17 Product Water Pressure Relief
The factory-installed product water pressure relief hardware includes two
1/4-inch thermoplastic pressure relief valves which relieve excessive
permeate backpressure based on a set point. Backpressure can be the
result of pressurized storage tanks, pressurized distribution loops,
restrictions in permeate plumbing and/or other factors which prevent
permeate from flowing from the machine. The valves are typically factory
preset to 60 psi (4.1 bar).
Allowing the machine to operate with permeate pressure greater than 60
psi (4.1 bar) may cause premature failure of the respective diaphragm
valve. The diaphragm valve is a “normally closed” valve that is designed to
fail in the closed position, as required for normal (non-divert) operation.
Should this valve fail, the machine will operate in the normal mode with
permeate flowing to the tank/distribution loop.
6.0 FEATURES AND ACCESSORIES
Accessory connections are provided on both the input and output terminal strips
of the ECM-100. Accessory outputs can be used to control chlorine or dispersant
feed pumps; accessory inputs can be used to control pre- or post-treatment
equipment. The output connections are switched by relays and power to the
outputs will be shut off if machine is turned off due to an alarm condition.
The ECM-100 allows you to connect to a printer and a personal computer. These
features allow you to store and print data on the 23G’s current and historical
performance.
