give an audible warning during an alarm status condition.

Elapsed Time Meter

An

 

elapsed time meter is mounted in the door of the Control Panel and will record the total hours

the unit has run.  This is important for maintenance and service scheduling.

High Pump Discharge Pressure Switch

A High pump discharge pressure switch can be mounted on the Control Panel.  It is adjusted to
shutdown the RO unit if the pump discharge pressure rises above the setpoint.  This will prevent the
pressure vessels from the possibility of over pressurization.

2.5  FUNCTIONAL DESCRIPTION

Below is a description of the function of the major system components and the features of the MAX RO
unit.

Feed Inlet Valve V-2

When the HOA switch is turned to AUTO or HAND, solenoid valve SV-1 will energize and the feed
water inlet valve will open.  It will remain open during operation and remain open for an additional 60
seconds after the RO pump stops.  The valve will not open if the pre-treatment lockout signal is active,
or if the call for water signal is inactive.

Feedwater Flow Sensor FE-1

The flow sensor in the feed line will send a pulse signal to the flow monitor.  The feed flow will be
displayed on the secondary display line, accessible by pressing the button on the monitor.

Feedwater Low Pressure Switch PSL-1

The pressure switch in the feed line will protect the RO unit high pressure pump from cavitation if the
feed pressure drops and remains below 10 PSIG for more than 10 seconds.  As soon as the alarm
initiates, the LOW FEED PRESSURE light will start to flash.  After the 10 second delay, the RO unit
will stop and the alarm horn will sound.  The 10 second delay is to accommodate a momentary pressure
drop when the pump first starts up.

Feed Conductivity Sensor  CE-1

A feed conductivity sensor will measure the conductance of the feed water and send a signal to the
conductivity monitor in the Control Panel.  The sensor has a 0.1/cm constant.  The feed conductivity
reading is used to calculate the system rejection. 

Feedwater Temperature Shutdown

The RTD in the feed conductivity sensor is used to measure the feedwater temperature.  This value is
displayed on the conductivity monitor.  If the operating feed temperature (user defined) is out of range,
the alarm initiates, the HIGH FEED TEMPERATURE light will start to flash, and the unit will shut
down.  There is no time delay, this is an instantaneous shutdown.  For standard TFC membranes, this
switch will be set to 100 degrees F.
