Powering Up the OIT
The apparatus manufacturer determines how the foam system powers up in
your application. However, when power is applied to the foam system, the OIT
displays the software version and then displays the water flow value.
Understanding the ON LED
The
(ON LED) indicates 3 states:
•
Solid on—The system is in standby mode waiting for a signal from the
flowmeter.
•
Flashing—The system is injecting foam concentrate.
•
Off—The system is not enabled.
Operating in Normal Mode
In normal operating mode, the OIT displays information from the flowmeter and
the foam % value to produce the desired mix.
Starting and Stopping the Pump
1. Press the
(FOAM button) to start the foam system and begin
injecting concentrate into the waterway.
2. Press the
(FOAM button) to stop the foam system and end
injecting concentrate into the waterway.
Adjusting the Mix Percentage
3. Press the
(SELECT button) until the PERCENT LED
illuminates.
4. Press the
(up button) to increase the percent by 0.1%.
5. Press the
(down button) to decrease the percent by 0.1%.
6. The display returns to FLOW RATE after 10 seconds without use.
Operating in Manual Mode
The foam system can operate in manual mode as required by the NFPA
regulation. While in manual mode, the foam system injects concentrate into
the waterway with or without water flowing. Use manual mode to troubleshoot,
prime and flush the pump.
Do not operate beyond
recommended pressure.
Liquid ejected at high
pressure can cause
serious injury.
High Pressure
•
•
Do not operate while all discharges or drains are closed. High
pressure results and damages the foam system, its components.
Enabling Manual Mode
1. Press the
(SELECT button) until the WATER FLOW LED
illuminates.
2. Press the
(up and down buttons) simultaneously for
2 seconds.
Note:
The foam system begins injecting the foam concentrate.
3. The percent LED illuminates.
4. The display shows the last value used. The pump is in manual mode.
