OPERATION HINTS FOR COMPETITOR DRYERS
Present Software version is 2.19
1. BURNER CYCLING
Keep Low pressure setting as low as possible without shutting down dryer or popping. Approx. 1 to 2 lb. Cycle on average 4 times per minute. 3
2. ERRORS
01 User switched from continuous flow to batch while dryer was running.
02 Grain Temperature Sensor Open. One or both leads are off (Open Circuit.).
03 Grain Temperature Sensor Leads are shorted together.
04 Plenum Temperature Sensor Open. One or both leads are off (Open Circuit).
05 Plenum Temperature Sensor Leads are shorted together.
06 Flame Probe Shorted to ground.
07 Illegal Flame Sense. Most likely caused by stuck open gas solenoid.
Error 7 will not shut down fan until loss of flame is detected by control. May occur if 1 of the 12 volt DC limits is shorted to AC ground, or to the communication port for the air switch or either temperature sensor is shorted to AC ground.
08 No safety circuit voltage.
09 I/O board communication failure. I/O board and Master board have lost communication.
10 User supplied safety. A safety connected to J7
11 Canadian Mercoid sensor. In USA jump
BATCH ERRORS
BRN on the screen means the Burner Switch is turned off or there is a loose wire in its circuit. FAN on the screen means the Fan Switch is turned off or there is a loose wire in its circuit. Presently the Load Switch and the Unload Switch are not monitored by the Dryer Controls.
999 on the screen is not a n Error. It means the board has never had software loaded. This will come up when you turn on the power just after GSI appears. This means the latest software must be down loaded.
3. DIP SWITCHES
1.Dip Switch 8 = Air Switch Test Bypass. WARNING! Bypassing this test will allow burner to come on without the Fan running.
2.Dip Switch 7 = Emergency Cooling Mode. Fan will run alone for 5 minutes when the Start button is pushed with switch on.
3.Dip Switch 6 = Allows Off/On Burner operation instead of High/Low as is standard.
4.Dip Switch 5 = (In Software Ver. 2.11 and up) Adds Low Temp Timer to a nd low Temp finish dry like dual temp. Batch Dryer.
5.Dip Switch 4 = (In Software Ver. 2.14 and up) Adds Low Temp finish tripped by Grain Temperature to Batch Mode.
4.SHUTDOWNS
If both the GRAIN and PLENUM HIGH TEMPERATURE warnings appear on the screen at the same time one of the two mechanical temperature sensors are kicked out. NOTE Emergency Cooling will NOT work if these are kicked out. These temperature limits are in addition to the electronics high limits and are located in the same electrical conduits as the electronic thermister sensors. Note that
12volts.
5.SPECIAL KEY USAGE
1.Pushing the UP arrow key will gives the Dryers Hour Meter reading. Two successive screens Hours x 100 Balance of hours.
In software vers. 2.14 and above it reads in 5 successive screens Total Hours x 100 Balance of hours Balance of minutes Batch Count Minutes since last shutdown. So 5 23 12 144 188 would be Timer = 523 hours 12 minutes, 144 Batches dumped and 3 hours and 8 minutes since the last shutdown.
2.Pushing the DOWN arrow key while an error is on the screen will tell how long ago the shutdown occurred.
3.Pushing the MODE SELECT key exits any mode back to the main screen.
4.Holding the STOP button for 4 seconds or longer causes the Dry, Cool, and Unload timers to be reset to the values programmed by the user. This also forces new times.
5.Holding down the HOURS key and turning on the power resets the NOVRAM or does what is called a HARD BOOT.
6.Holding down the DOWN key while turning on the power restores the factory default settings.
7.In software vers. 2.19 and above Holding down the Up Arrow Key while powering up resets the Total Batch Counter .
