8.1 GENERAL DESCRIPTION OF OPERATION
8.1.1 CONTROLLER MODES OF OPERATION
The GI-2000 G.R.D. controller provides the following modes of operation:
Automatic Clean Cycle Mode
This operating mode automatically starts the clean cycle that pumps the grease out of
the interceptor trap whenever the volume of grease reaches the preset level.
Manual Clean Cycle Mode
Allows the operator to manually start the clean cycle independent of the volume of
grease in the interceptor trap. Note: In manual mode operation the Grease Level HI LED
indicator will light when the volume of grease reaches the preset level.
Calibration Mode
The calibration mode allows maintenance personnel to calibrate the water level
measurement sensor located in the interceptor trap. Calibration consists of filling the trap
with water to two (2) predetermined levels that the controller later uses to calculate the
water level in the interceptor trap during actual operation. The calibration mode also
allows the user to configure system operating parameters.
Clean Cycle Rate Adjust Mode
The clean cycle rate adjustment allows the grease volume threshold at which the clean
cycle automatically starts to be adjusted without re-calibration of the system. The normal
rate is based on the calibration of the system at installation and setup. Adjustments are
made in software to the water level at which the clean cycle starts relative to the results
from the initial calibration. The clean cycle rate will increase when the water level value
at which the clean cycle starts is raised and the clean cycle rate will decrease when the
water level value is decreased. This mode allows maintenance personnel to quickly and
easily adjust clean cycle rate to better match the requirements of a specific installation.
Test Mode
The test mode allows maintenance personnel to exercise various system functions to
facilitate trouble shooting and repair. Table 1 provides a summary of the available test
functions:
