CommunicationPortCongurationfortheStandard
Application Program
COM1 – Local RS 232 port for conguration via a
PC. Flash conguration is BSAP Slave, 115.2K
baud rate. The PC port connector, that is acces-
sible, externally, on the bottom of the front door, is
connected to this port on the CPU.
COM2 – RS 232 Network port with Flash congu-
ration of BSAP Slave, 9600 baud. The standard
application program is compatible with an external
communication device (via RS 232) or standard
model radio. If a standard model radio is included,
the model will also include a cable that connects
this port, on the CPU, to the RS 232 port on the
radio.
COM3 – RS 485 port with Flash conguration of
BSAP Master at 9600 baud. The standard ap-
plication program assumes that 3808 MVT smart
multivariable transmitters for meter run measure-
ment are to be interfaced to this port.
The standard application program also supports a
chromatograph but a Flash Conguration change
is required to allow the chromatograph to be inter-
faced to COM3.
POWER SYSTEM
You can specify the solar/battery power system.
For most applications, the 12V, 33 Ampere-hour
(AH) battery, that is internal to the housing, can be
matched with either a 30-watt or 40-watt, 2” mast-
mounting solar panel.
In addition, a lithium battery pack can be specied.
This 7.2V, 35 AH, non-rechargeable battery pack
is used to back-up the primary power system. The
primary power system is either the internal, 12V, 33
AH battery or an external power source.
Note that the lithium battery won’t provide power
sufcient to operate devices, such as radios, that
require 12V nominal power. If the primary power
source fails, the lithium battery will be sufcient to
operate the electronics for an extensive time—nor-
mally plenty of time to repair the primary power
source.
For power loading details, please refer to the Bristol
product data sheet entitled, “ControlWave GFC
Power System Sizing.”
Note that system sizing “red ags,” which may tell
the user to specify a larger, external power source,
include multiple analog loops that operate from the
24V dc/dc power supply rather than 12V and opera-
tion of a standard model radio with power constantly
on rather than duty cycling.
The 40 watt panel may need to be selected for
locations that receive less than 2 sun-hours per day.
Again, the Power System Sizing data sheet pro-
vides further information.
A charge regulator is always included with the solar
panel and must be installed inside a compartment
on the back of the panel.
If external dc power is available and the user pre-
fers that, exclusively, the “none” selection is appro-
priate.
A peculiarity in selection of the power system is that
the BP solar panels are FM approved for operation
in Class I, Division 2 areas while the ControlWave
GFC Plus, including the internal battery, is approved
for the same by UL.
Therefore, a UL-approved model is ordered by
specifying the battery but without the solar panel.
The solar panel is then specied by part number.
