8.1.3 TYPICAL CONTROLLER OPERATION
The following sections describe typical GI-2000 controller operation:
Typical Controller Power ON
When power is first applied to the GI-2000 the unit will beep and go through internal
diagnostics (See Section 8.7 for typical display messages after initial power ON or
reset). Should any part of the diagnostics fail, the unit will beep every 5 seconds and
display a message about the failure. The critical values of time/date, pump run time,
and calibration values are stored in the unit and tested at start up. Should one of the
values be determined to be invalid, the unit will wait for the user to re-enter the correct
values. See Section 8.4 for a detailed description.
Typical Automatic Cycle
When the unit is in the set to Automatic mode it will perform the entire cleaning cycle
automatically. Automatic mode is entered when the front panel Auto Mode Switch is
pressed and the Auto Mode LED is ON. The controller LCD display indicates the
controller is in the Automatic mode. When the grease quantity builds up to the preset
level, a horn in the control unit will sound for 10 seconds. This is intended to alert
personnel using the sinks that the automatic cleaning cycle is about to start.
Note:
No
more water should be introduced into the interceptor drain system during the clean
cycle
.
At this point, the user can delay the operation of the unit by hitting the Start/Stop
button on the controller front panel. If Start/Stop button is pressed, the controller will
halted the clean cycle for 30 minutes as indicated on the controller’s LCD display. If a
longer delay period is needed, the unit can be placed in the manual mode by pressing
Manual Mode Switch. If the automatic clean cycle is allowed to continue the controller
LCD display will show a 45-second count down to start of the clean cycle operation.
After 45 seconds, the unit will turn on the heaters and the CYCLE ACTIVE indicator on
the controller front panel will turn on. The controller LCD display will indicate the heaters
are on. The heaters will remain on until the grease temperature is ~120 degrees F or 4
hours. Once the temperature is reached, the interceptor will pump the grease out. If 4
hours pass and the temperature is not reached, the interceptor will pump the grease out.
The controller LCD display will indicate the pump is on and the pump time remaining.
After the pump cycle is complete, the controller will beep again and the LCD display will
indicate the cycle is complete. At this point, normal use of the sink can resume. The
controller will not allow an automatic clean cycle to run again for a minimum of 12 hours.
Note
: The automatic cycle can be interrupted at any time by either pressing the
Start/Stop button on the front panel of the control unit or by pressing Manual Mode
Switch.
