SECTION 9: MANUAL CONTROL OPERATIONS
9.1 PAUSE STATE
The PAUSE State function is to allow for special occurrences in the operation of the GranuFlo Dissolution
Unit II. For example; if the unit is not working properly or the operator needs to PAUSE any operation,
then the PAUSE button may be pressed.
This will cause the Indicating Light for the current step of
the operation to flash. Pressing the PAUSE button will
disable the pump, drain valve, fill valve, etc. To continue
the cycle, press the START button and the timers will
resume.
The FILL Operation cannot be paused.
9.2 STEP MODE
The STEP MODE function is intended to be used during the Disinfection Operation or when it is
necessary to discard an incorrectly mixed batch of solution. The STEP MODE function has the ability to
skip critical steps in the Dissolution and Rinse cycles. Using this mode during these cycles can cause
unintended operation of the GranuFlo Dissolution Unit II resulting in incorrectly mixed solution.
To enter the STEP MODE press the STEP MODE ON/OFF
button until the Step Mode Indicator Light illuminates. The
system will enter the STEP MODE and all operations will be
suspended.
Press the STEP button to step to the desired operation. When
the desired operation light becomes illuminated, press the
ON/OFF button and the operation is continued.
