2.1.1 BATTERY CHARGER/AC ADAPTER
The battery charger/AC adapter has a removable AC power cable and converts 110-250
volt AC to 15 volts DC. The DC power output cable connects to the breakout box at the
DC input connector .
When connected to the breakout box, the battery charger/AC adapter performs the
following functions:
!
Charges the flowmeter battery through the 7-pin circular connector
!
Provides immediate power to operate the unit if the battery is discharged
!
Provides voltage to charge/power the printer as required
!
Provides the driving voltage for the 4 to 20 mA current output if configured to drive the
loop.
2.1.2 PRINTER
An optional external thermal printer is available for use with the flowmeter for printing
flow data, diagnostic messages, etc. For complete printer operating instructions, refer to
the instruction manual supplied with the printer.
Charging the Printer Battery
The printer battery is charged by connecting the printer to the printer power cable on the
breakout box (when the battery charger/AC adapter is connected).
CAUTION:
Note the following precautions:
!
The printer battery charge time for a fully discharged battery is 15
hours. To avoid damage to the battery, do not charge for more than
24 hours.
!
Do not connect the battery charger/ac adapter directly to the printer
to charge the printer battery. The voltage and polarity output of the
charger do not match the required input of the printer. If they are
directly connected, the printer battery can explode or the printer can
be seriously damaged.
Printing Procedure
To print from the flowmeter:
1. Connect the printer cable from the serial port on the printer to the printer port on the
upper left of the flowmeter’s control panel (Figure 1-3).
NOTE:
The printer port on the panel is covered with a protective metal cap.)
2. Follow the procedures for using the print menus in Section 3.6.14.
