Charging Status
For battery charge status, refer to the front panel’s red BATT CHG light.
•
If the BATT CHG light extinguishes then the battery is fully charged.
•
If the BATT CHG light does not extinguish after several hours of
charging, turn the unit OFF and back ON.
•
If the light remains illuminated then continue to charge the unit for a few
more hours and retry turning the unit OFF and back ON.
•
And if the light still does not extinguish then replace the unit’s battery.
Charging from the Charging Module
If the internal battery has become discharged, recharge it by plugging the DC
output plug on the Charging Module’s cable end into the recessed receptacle
on the instrument’s rear panel and plugging the Charging Module into the
local AC supply. Ensure that the voltage rating of the Charging Module is in
accordance with the local AC supply voltage.
Note:
For the fastest possible recharging time, place the front panel POWER
switch in the OFF position.
While charging the internal battery, the BATT CHG light will be illuminated.
When this LED becomes extinguished, the internal battery is fully charged.
The instrument can be operated while it’s charging. Note that when doing so,
to fully charge the internal battery may take up to 15 hours. If the instrument
is not operated during charging then a full charge will take up to 12 hours.
Caution:
If the instrument is connected to other circuitry or instrumentation
when the Charging Module is connected, ensure that less than 500V of
common mode potential to ground is present,
SEVERE DAMAGE could
result if excessive common mode voltages are present.
Warning:
Prior to recharging the internal battery disconnect the 2000
instrument from any intrinsically-safe process control system. Charging while
connected could adversely affect the safety of the process control system.
