19. COMPUTER input / output
If you choose to gather material usage data automatically and
continuously by computer, this connector allows for connection to an
IBM PC type computer operating under MS-DOS or WINDOWS.
The COMPUTER port is a DB9 (9 pin) male port. You will need a
specially wired cable from us to connect to the serial output on your
standard PC computer. You will also need software from us for
communicating with your Weigh Scale Blender. Your computer operating
system must be MS-DOS or WINDOWS. This software allows downloading
settings and retrieval of information and will produce extensive
reports for those customers who wish to take advantage of this feature.
One or many Weigh Scale Blenders can be connected to one computer.
Customers that wish to do their own programming may interact with the
Weigh Scale Blenders by way of a single program that we provide. This
program, when executed, gathers all current totals from all controllers
and moves them into an ASCII text file for access by other software.
For multiple Weigh Scale Blender systems, or communication over long
distances, an additional piece of hardware is required. All GB/WSB
controllers are fully programmed to communicate with your computer now
or at a later date.
20. PANEL FUSE for duplex receptacle - 3 amp
Fuses the common power wire of the duplex receptacle (the color and
additive outputs). Since these outlets are only turned on one at a
time, each is protected to the full 3 amp rating of the fuse.
21. PANEL FUSE for processor - 1/2 amp
Fuses power to the circuit board power supply which includes all
solenoid outputs and solid state relay outputs.
22. INTERNAL FUSES
An in-line fuse is provided internally to protect the main 120 volt
power cord supply (10) amps. If this fuses blow, an internal short
circuit is indicated and we don't recommend that you try to fix it.
Remember, this unit carries a five year warranty; just send it back.
The MIX MOTOR timed power source and the AUGER FEEDER OUTLETS are
driven by internal solid state plug-in relays. These relays are
located on the circuit board mounted on the inside back surface of the
controller enclosure. A small 5 amp glass fuse is located to the right
of each relay. A spare fuse is also located on the board if
replacement is necessary.
23. KEYPAD
The KEYPAD is explained extensively in the next section, next page.
