Advantage Sentra SR Series User manual

Sentra SR Series with G300 Control Instrument
This reference guide covers standard Advantage temperature control units
with the G300 Series Control Instrument.
This guide may be used for customized units using the G300 Series Control
Instrument even when the unit may not be physically the same as the units
depicted in the included photos.
Before Installing or Operating
1. A manual is available at www.advantageengineering.com/Sentra-SR-G300_Manual or by
scanning the QR code on the back of this document. Download and read the manual before
starting installation.
2. This unit is designed to be used with water as the circulating fluid. The quality of fluid used in
your temperature control unit will greatly effect its short and long-term operation. Lack of as
well as improper water treatment can damage the temperature control unit by causing scale
build-up, excessive corrosion and/or bacterial contamination. It is the equipment owner’s
responsibility to prevent damage caused by poor water quality. The services of a water
treatment professional is recommended.
3. Before installing and operating the unit, be aware of and follow any local laws and codes that
apply to the installation.
4. When contacting the Service Department always have the unit Model and Serial number from
the data tag located on the side of the unit.

Installation
1. Electrical: Be certain all electrical connections are tight in
the unit. Install unit power cord (when supplied) to power
disconnect switch. Applied power must be equal to the unit
voltage and amps listed on the unit data tag. Follow all
applicable local and national electrical codes.
2. Plumbing: Care should be taken to use materials (hose,
rigid piping, valves or filters) rated for the temperature and
pressure duty of your unit. Most units have a maximum
operating temperature of 300°F or less and a maximum
pressure of 150 PSI. The unit is most efficient when full
size plumbing is run from the unit connections to and from
the process. If necessary, reduce the plumbing size at your
process, not at the unit.
3. Connect the unit’s To Process port to the Water In port on
the process manifold.
4. Connect the unit’s From Process port to the Water Out port
on the process manifold.
5. Note: Circuitry should avoid an excessive use of elbows
and/or lengths of pipe or hose. If hose is the material of
choice, avoid tight twists or curls and excessive lengths.
6. Valves and lters may be installed in the process water
piping circuitry to facilitate service and maintenance,
provided that such devices maintain the full inside diameter
of the process connection. If installed, all such devices must
be open and clean during unit operation.
7. Connect Unit drain to plant’s open drain, tower water
system return or chilled water system return. The factory
recommends a minimum of 20 psi pressure differential
between the water supply and drain line. A larger differential
may be required for larger cooling needs.
8. Connect Unit water supply to plant’s city water or well
water source or tower water supply or chilled water supply.
Water supply pressure requirements vary with operating
temperatures as shown in the chart below.
WARNING: proper care should be employed when checking pump rotation as
power is applied to the unit at this point.

Starting Unit
1. Fill unit with water. Apply power. The Standby screen will illuminate. When Standby is displayed,
the unit is not running.
• Status : Ready. Indicates the unit is ready to start.
• Status : Not Ready. Indicates the presence of a sensor probe,
pressure switch or motor overload fault. See the troubleshooting and
maintenance portions of the manual for Information. The fault must be
corrected in order to continue operation of the unit.
2. Determine the pump is rotating in a clockwise direction when viewed
from the rear of the motor. Instructions are in the operations manual.

The instrument has 5 soft keyed buttons.
1. The Home button shows the Home screen.
2. The Up button will add one unit of value or will scroll up through a menu.
3. The Down button will subtract one unit of value or will scroll down
through a menu.
4. The Go button will advanced through a series of screens or save a
value.
5. The Back button will go backwards through a series of screens.
WARNING: When the pump seal cooling
feature is activated, pressing the stop button
will not turn off the unit. To completely shut
down the unit, press the Stop button twice.
3. The unit is ready to start when the Status
: Ready is shown on the screen and
pump rotation is correct. Press the green
start button. The unit will auto vent if the
fluid temperature is below 100°F or as
programmed in the features menu.
4. Adjust the setpoint to the desired value by
pressing the Up or Down button until the
value is displayed. The unit will heat or cool
to maintain the setpoint temperature.
Stop Unit
Starting Unit continued
1. Decrease the setpoint temperature lower
than 85°F and allow the unit to cool to the
temperature.
2. Press the Stop Button to disengage the
pump.
3. Caution. Dissipate static pressure prior to
disconnecting hoses.
4. A pump seal cooling feature can be selected
from the features menu to automatically cool
the unit once the stop button is pressed.
Operating Screens ... these show the To Process temperature, the selected Setpoint temperature
and status of Autovent, Heating and Cooling. When enabled, the Pump Seal Cool screen appears
when the unit is stopped. The pump will continue to run and the cooling valve will open 100% to
reduce process temperature prior to shutdown.
Setpoint ... use the Go button to advance to the Setpoint
select screen. Use the Up and Down buttons to select the
setpoint. Save the setting by pressing the Go button.
