Unit Start Up
RT-SVX36K-EN 105
7. With the exhaust dampers open and the exhaust/
return fan operating at full airflow capability, measure
the amperage at the exhaust fan contactor 1K17. If the
amperage exceeds the motor nameplate value, the
static pressure is less than design and airflow is too
high. If the amperage is below the motor nameplate
value, static pressure may be too high and CFM may be
too low.To determine the actual CFM (± 5%);
a. Measure the actual fan RPM
b. Calculate theTheoretical BHP
Use Table 50 - Table 52 to calculate a new fan drive if the
CFM is not at design specifications.
8. Press the STOP key at the Human Interface Module in
the unit control panel to stop the fan operation.
Traq Sensor Airflow Measurement
(Optional with all units equipped with an
economizer)
1. Open the Human Interface access door, located in the
unit control panel, and press the SERVICE MODE key to
display the first service screen. Refer to the latest
edition of the appropriate programming manual for CV
or VAV applications for the SERVICETEST screens and
programming instructions.
2. Use Table 42, p. 96 to program the following system
components for Economizer operation by scrolling
through the displays;
– Supply Fan (On)
– Outside Air dampers (Selected % Open)
– Variable Frequency Drive (100% Output, if
applicable)
– RTM Occ/Unocc Output (Unoccupied)
– Outside Air CFM Setpoint
– Outside Air Pre-Heater Operation (if applicable)
3. Once the configuration for the components is
complete, press the NEXT key until the LCD displays
the “Start test in __Sec.” screen. Press the + key to
designate the delay before the test is to start.This
service test will begin after theTEST START key is
pressed and the delay designated in this step has
elapsed. Press the ENTER key to confirm this choice.
4. Press theTEST START key to start the test. Remember
that the delay designated in step 3 must elapse before
the fans will begin to operate.
5. With the unit operating in the “TEST MODE”, the
amount of outside air flowing through theTRAQ
sensor can be view by switching to the “STATUS
MENU” screen “OA CFM”.
6. Scroll to the “ECONOMIZER ENABLE/ECONOMIZER
POSITION” screen by pressing the “NEXT” key and
read the corresponding damper opening percentage
(%).
7. Press the STOP key at the Human Interface Module in
the unit control panel to stop the unit operation.
Return Plenum Pressure Control (Units
equipped with Return Fan)
“Return Plenum Pressure Max Setpoint” determination:
1. Open the Human Interface access door, located in the
unit control panel, and press the SERVICE MODE key to
display the first service screen. Refer to the latest
edition of the appropriate programming manual for CV
or VAV applications for the SERVICETEST screens and
programming instructions.
2. If not already STOPPED, press the STOP key on the
Human Interface (HI)
3. Under HI Service Menu, insure all outputs are OFF or
CLOSED.
4. Press the Start ServiceTest key.
5. Adjust the Exhaust Damper Position to approx. 85%.
6. Start the Supply Fan and Return Fan.
7. Adjust the Supply Fan and Return Fan speeds to 100%.
8. Slowly adjust the Outside Air Damper to approx. 100%.
9. While measuring the building static pressure, slowly
adjust the Return Fan Speed down until the building
pressure reaches design conditions.
10. Make note of the return plenum pressure reading on
the HI.
11. Set the “Return Plenum Pressure Max Setpoint”
parameter on the HI to the value noted in the previous
step.
“OA Normalization” determination (Units equipped with
TRAQ):
1. Perform a normal airflow balance of the unit.
2. Insure Exhaust Damper is approx. 85%, and the Supply
Fan and Return Fan speed is 100%, and the Outdoor Air
Damper is approx. 100%.
3. Make note of the totalTRAQ airflow reading on the
Human Interface (HI).
4. Set the “OA Normalization” parameter on the HI to the
value noted in the previous step.
