Important Software and Troubleshooting tips
Special Wire Terminals - The third unused terminal on any network connector is a 12 V ground
for use with a tester.
1. When ever you install a new display board. After you flash the software in and restart you may see an
ERROR Message with some garbage characters or a negative number for temperature such as -2785
degrees. Do a Hard Boot by holding the Reset key and turning the power on to correct this stuck register
value.
2. Always do a Hard Boot after installing a new Display board.
3. If you have a blank or all black screen see the Contrast Adjustment in Tip #1
4.
Also when flashing new software to the IO Board turn off the load auger breaker(s). Due to a design
characteristic the load auger(s) will run whenever the IO board is being flashed.
5. If the Fan motors run, but the augers and aeration fan do not, make sure the 110 volt breaker on the IO
board is turned on.
6. The
newest Display boards (5/1/02)can now be used on either a Topdry or Portable Dryer. In the past a
Dryer Display board
had to have wires soldered in place for the Meter Roll Speed Pot and they can also be used on either a
Top Dry or Portable
Dryer.
The past Top Dry Display board without these wires could be used on a Top Dry only. The
newest boards now have a
six pin connector that the Dryer Meter Roll Speed Pot is connected to.
7.
If you get a plenum High Limit Error on startup with a new system or after installing new software on a
Two Fan Top Dry
check to see if a jumper from J7-3 to J7-15 fixes it.
8. Grain Temperature Sensors are 10 ½” from the top of the floor rib. Older Top Drys were 14” from
the flat of the floor.
