Chapter 3. Using Your APS3
3.3
Using the APS3 Controls
APS3 devices are designed to operate “hands free” in normal use.
• The unit is turned on by inserting the unit in the charging case and applying power to
the charging case.
• The unit is completely turned off by activating the “shutdown” button in the
ParticleSpectrum software..
• A “shutdown” turns off all internal electronics in the APS3. After a shutdown the
unit must be restarted in the charging case. Therefore, if the intent is to put the unit
into standby mode, where the fan and laser are turned off but the electronics are
still active, the “stop” button in the ParticleSpectrum should be used instead of the
“shutdown” button.
• In abnormal situations, the reset switches on the front panel can be used to activate a
shutdown or to turn the unit on from a shutdown. See page 1.2 for a view of the reset
switches. The button indicated by “1” turns the unit on. The button indicated by “0”
turns the unit off.
Using the APS3 Indicators
APS3 devices have the following status LED (see illustration on page 1.2)
• Charger On. Glows green when power is applied to the charging case.
• Charging. Glows red when the unit is being charged. Goes dark when the battery
has reached 100% charge. Glows red if the charger is connected and the battery
discharges below 95%. Goes dark when the inductive charger is no longer powered.
• Unit On. Indicates when the device is on.
• Connect/Pair. Note: Glows green when the unit is successfully paired with a link
box. Blinks red/green slowly when it is searching for a link. This usually occurs just
after turn on or before the link box is powered by the host computer. Blinks red/
green rapidly when the pairing function is activated by the “C” reset switch. This rapid
blinking indicates it is receptive to a new pairing.
• When the APS3 device is on and has been removed from its charger and is ready for
in-tool use, the “Unit on” and the “Connect/Pair” LEDs should both be glowing
steady green. The APS3 device can be operated inside the charging case. However, do
not connect the charger while operating the APS3 inside the case.
