5. When the applied (or removed) weight exceeds the programmed amount, the
alarm will sound and the
DONE
indicator will flash on the display.
6. Press any key to stop the alarm.
7. To cancel the RUN mode at any time, press the “RUN/STOP” key.
NOTE:
The RUN mode can only be initiated from the SET mode. If you cancel the
RUN mode by pressing the “RUN/STOP” key and wish to RUN again, press the
“SET” key (the previous set point will be restored) followed by the “RUN/STOP” key
again. The display will be zeroed when the program restarts. You may program the
SET mode without starting the RUN mode by pressing the “SET” key after setting the
program set point. The new value will be saved until next time the SET mode is acti-
vated. The “HOLD” key can be used during the RUN mode similarly as described in
the HOLD MODE section.
It is often convenient to know the relative amount of material (i.e. refrigerant) remain-
ing in a container (tank). The Tank Capacity Mode allows a continuous display of the
percentage of material remaining in a tank. In order to compute the percentage accu-
rately, the 68860 must be trained to know the weights of an empty and full tank. To
train the 68860 Tank Capacity Mode, perform the following steps:
1. While holding the “ZERO” key down, press the “SET” key. The
SET TANK
indicator will turn on, and
OFF
will show on the display. This indicates that the
Tank Capacity Mode is currently off.
2. Turn the Tank Capacity Mode on by pressing the “UP” key. The display will
show
ON
, and the Alternate Numeric Display and Percent Indicator will turn on.
3. Press the “SET” key to proceed to the first step of training.
0%
will flash in the
Alternate Numeric Display indicating that the weight of an empty container must
be registered.
4. Apply an empty container (or a load representing the weight of an empty con-
tainer) on the platform. Wait 5 seconds for the load to stabilize, then press the
“SET” key.
100%
will flash in the Alternate Numeric Display indicating that the
weight of a full container must be registered.
5. Apply a full container (or a load representing the weight of a full container) on
the platform. Wait 5 seconds for the load to stabilize, then press the “SET” key.
This completes the training process, and the
SET TANK
indicator will turn off.
6. From this point forward, the Alternate Numeric Display will show the percent of
material remaining in the container from 0% to 100%.
NOTE:
The 100% weight must be larger than the 0% weight by at least 200g (0.44
lb). If not,
“Err”
will show on the Alternate Numeric Display. To clear the error,
retrain as above using a 100% weight that is at least 200g larger than the 0% weight.
During training, the ZERO key may be used to assist in setting the 0% and 100%
values. This will have no effect on the training, as the Tank Capacity Mode relies on
absolute, not relative, weights.
