2.2 POWER SUPPLY
• Power can be supplied using an internal re-chargeable
battery provided within the indicator case, or from mains
power.
•
If the battery is low on charge the symbol on the LCD will
show just one bar meaning the battery needs to be re-
charged immediately. While the battery is being re-charged,
this symbol will show four bars.
• With the internal re-chargeable acid battery, the battery life is
approximately 60 hours. The battery life will vary depending
on the use of the backlight
2.3 LOAD CELLS
• To connect the AE 301 indicator to a new base it is
necessary to connect the load cells properly. Then set the
parameters for the weighing system.
• User should ensure the load cells are correct for the purpose
and the signal from the load cell is correct.
• Note that it may not be possible to measure the voltage
signal from the load cell with all DVM. Some DVM will
measure the Excitation and signal voltage while others will
not. Try measuring the excitation voltage to determine if your
voltmeter will work.
CONNECTING TO LOAD CELLS
The AE 301 is supplied with a connector to connect an external
load cell.
The load cell can be connected in either a 4 or 6-wired
configuration. The standard connection is 4 wired.
Pin 1 Excitation +
Pin 2 Excitation –
Pin 3 Signal +
Pin 4 Signal –
