OPERATION
TWO SPEED, A then B OPERATION
This method of the 748P Digital Fill Control fills one ingredient up to a Preset Target
weight limit minus a stored Trim weight. It controls two relays (preset #1 and #2) to start
the fill operation at a one rate then change to a different rate before stopping.
Note that
this Digital Fill Control feature must have been set to a “3” during setup and calibration
of the 748P to be operational.
To start a fill operation:
1. With the indicator in the Gross Weight mode (the Gross annunciator on), press
the PRESET key.
2. The display will change to fast=, the prompt for the fast cut-off point weight.
Press the ENTER key to show the current value. If the setting displayed is
acceptable, press the ENTER key again to save it. Otherwise, using the
numeric keys, enter the fast cut-off weight and press the ENTER key. Note, the
fast cut-off weight is stored in non-volatile memory.
3. The display will change to slo=, the prompt for the slow cut-off point weight.
Press the ENTER key to show the current value. If the setting displayed is
acceptable, press the ENTER key again to save it. Otherwise, using the
numeric keys, enter the slow cut-off weight and press the ENTER key. Note,
the target weight is stored in non-volatile memory.
4. The display will change to tr=, the prompt for the stored Trim Weight. Press
the ENTER key to show the current value. If the setting displayed is
acceptable, press the ENTER key again to save it. Otherwise, using the
numeric keys, enter the trim weight and press the ENTER key. Note, the trim
weight adjusts automatically and like the target weight is stored in non-volatile
memory.
5. With the indicator in the Gross Weight mode (the Gross annunciator on), press
the START/STOP key.
6. The BIN/PWC annunciator will turn on and the weight display will change to
start= the prompt to start the actual fill operation. Press the 1 key (1=YES) to
begin the operation, then proceed to step 7
OR
to abort the operation and
start over, press the 0 key (0=NO).
7. The two bar graph elements directly beneath Preset #1 will be turned on, the
relay will turn on and the fill operation will begin
8. When the displayed weight reaches the fast cut-off point (FASt=), the A relay
and the two bar graph elements directly beneath Preset #1 will be turned off.
9. Next, the two bar graph elements directly beneath Preset #2 and the B relay will
be turned on. The B relay will remain until the weight reaches the slow cut-off
point (SLO=).
