3 USING HART Communicator HARTCOM-W2
3.1 Charging the HART Communicator HARTCOM-W2 and the Bluetooth HART Modem
Note: the HART Communicator has a “
Barrel
” connector, whereas the Bluetooth HART modem has a “Mini
-
USB”
connector. Hence the supplied USB leads have different connectors on them as shown below.
Using the supplied 4 port USB wall charger, the HART Communicator and Bluetooth HART modem can either be
charged separately, or together as shown below.
3.1.1 Recharging the HART Communicator
The HART Communicator Windows Tablet can be recharged at any time, whilst turned on or turned off. If turned off
the charging progress is indicated by the Windows Operating system in the bottom right hand corner of the display.
If the tablet is turned off (shutdown) it will show the current charging status when the charge lead is first plugged in.
3.1.2 Recharging the Bluetooth HART Modem
The Bluetooth HART Modem can be recharged at any time, whilst turned on, or turned off. While actively charging
the “Charge On” LED will illuminate, when completely charged the LED
will turn off. When the battery is almost full
the “Charge On” LED may blink. If the “Charge Error” LED illuminates, disconnect the Bluetooth
HART Modem and
allow it to cool down. The normal cause for “Charge Error” is an excessively hot battery. If when
you connect the
modem the “Charge On” LED
blinks once and then stays off, the battery is already fully charged.
Rechargeable Lithium Ion batteries are very reliable so long as they are not abused. They maintain charge very well,
after 1 year of storage they typically have 75% of the charge remaining. Hence you can use and recharge them
without worries associated with many other battery technologies, e.g. Lithium Ion batteries do not suffer from
battery memory. As an engineer you may be interested in how to optimise battery life/performance, if so all the
normal recommendations for lithium batteries (Li-Ion, Li-Po) apply:
