NOTE:
Battery shelf life is rated at 10 years by manufacturer
Life expectancy based on rated battery capacity at
20°C
The above table is shown with pulse output inactive.
Use of pulse output shortens battery life.
Example: A pulse output of 0.06 sec. duration, once per sec-
ond, would derate the battery life by 20%.
IDATA STORAGE:
Setup Information: Stored in flash memory
Totalizer: Stored in battery backed RAM but can be saved to
flash memory by operator for recall after battery change out.
COMMUNICATIONS OPTION (S1):
RS232 SERIAL SETUP SOFTWARE OPTION:
This option enables you to access a variety of process param-
eters through serial communications. PC compatible com-
munications software is included with this option. With this
software and a BAT R/T-M Serial Adapter Cable (BSAC1) you
will be able to setup the BAT R/T-M through your PC.
RS-485 MODBUS and DATA LOGGER OPTION (S2):
The optional RS-485 card utilizes Modbus RTU protocol to ac-
cess a variety of process parameters. The Data Logger stores
the totalizer to flash memory once every 24 hours at the time
you set. The data logger can hold 27 days of totals, on the
28th day the oldest total in the logger is dropped. Requires ex-
ternal DC power: 6-28VDC (input is reverse polarity protected)
Current Draw:
Receiving: 2 mA
Transmitting: 125 mA (instantaneous peak)
