Memory Backup
The BW500 requires no maintenance or cleaning, other than a periodic replacement
of the memory backup battery. Refer to Installing/Replacing the Memory Back-up
Battery on page 27.
Software Updates
The software can be updated from a floppy disk by use of a PC (IBM Compatible)
with Milltronics Dolphin Plus software.
It is recommended that the old software and parameters be saved to your PC before
downloading the new software.
Once installed, a master reset (P999) must be done.
The parameters can then be reloaded, either manually or downloaded from the
previously saved file. If downloading parameters via , confirm that BW500 is
in Program mode. The zero and span values are included in the parameter file,
However, new zero and span calibrations should be done regardless, and as soon as
possible to insure operating accuracy.
Calibration Criteria
Zero:
•
belt must be empty
Run the conveyor for several minutes to limber the belt and ensure that it is empty.
•
test weights or chain are not used during a zero calibration.
•
conveyor running at normal speed
Span:
•
a zero must be done prior
•
belt must be empty
•
test weight or chain must be applied.
•
conveyor running at normal speed test reference (chain or weight applied)
PID Systems:
•
zero and span criteria must be met
•
set controller (P400) to manual and adjust the output for 100% belt speed (using the
4 and 8 keys).
If the PID is not set to manual, the speed output will be the last value prior to
starting the zero or span calibration
•
shut off the prefeed to conveyor
In process where a prefeed device is included, it must be turned off to ensure
that no material is fed onto the belt.
