VERSION: 2.15
REVISED BY: Steve Logue RELEASE DATE: Oct 17, 2002
NOTE: This Version does NOT support Watchdog and the Heater Version MUST be 1.09. HEATER VERS – 1.09 IO
VERS – 1.07
1) The " FAN DELAY " is now called " MOTOR DELAY ".
2) Added a way for GSI to reset total hours.
3) Here is a list of switches/features which can be found under the setup screens accessed via
holding in on MODIFY while
powering on the Control Power .
Below is a description for each defining what it means to disable/enable them:
i) AIRSWITCH -> Enabled means you will get a shutdown when a fan loses airflow. Disabled will satisfy the dryer's airflow
requirements for the burner
regardless of the actual air switch state.
ii) LOW LEVEL SWITCH -> Enabled means the drying chamber low level switch will act as normal, i.e, will indicate the real
state of the rotary switch.
When disabled the dryer will think the low level switch is always covered.
iii) WET TANK SWITCH -> Enabled means this switch will act as normal. Disabled means the dryer will think this switch is
always covered with grain.
iv) START FANS WITH HIGH -> Enabled means the dryer will start fans according to state of drying chamber hi level switch.
Disabled means dryer will
start according to drying chamber low level switch.
v) AERATION FAN BYPASS -> Enabled means the BYPASS is active, which allows the aeration fan to continue to run after a
dryer shutdown.
4) The
REFILL TIMER and the TIME UNTIL LOAD OFF screens are only shown when the dryer is set for Autobatch mode .
5) There are two more settings available under the "Power on and Modify key in" sequence for the user to set how many degrees a
measured temperature can
exceed a setpoint without causing an overheat. The user can set
10 -> 50 degrees above the setpoint to be an overheat condition.
The default for the plenum
temp is 20F and the default for the grain temp is 30F .
6) The low level rotary switch function is the same as it was in 2.14, but now instead of giving a warning which states " DRY
CHAMBER EMPTY " when
it becomes uncovered it gives " LOW LEVEL SW EXPOSED ."
7) Added an Out of Grain Timer . The time value can be changed under the setup button. This timer starts whenever either fill
systems is running and the load
switch is in the auto position. The timer is reset when both load augers stop. If the timer runs out of time an
OUT OF GRAIN
warning is issued. The
default is 20 minutes. Any time the value of this Timer is changed the new value takes effect immediately.
8) Changed warning for wet bin empty to state "
WET BIN SW EXPOSED " instead of saying “ DRYER OUT OF GRAIN ”.
9) Renamed " FILL 1 DELAY " to " FILL SYSTEM #1 ". Changed name of " FILL 2 DELAY " to " HI LEVEL SW ". The HI
LEVEL SW delay is always
available on both one and two fill system dryers and is used to make sure the dryer is full so you don't get bogus shutdowns. The
FILL SYSTEM #1 delay is
only available when you are set for two fill systems and it is used to establish auger cleanout time.
10) If the
Storage Bin High Limit is detected as failed (the N.C. pin and the N.O. pin from the switch are both reporting the same
voltage, 0 or 12 volts) a
warning is reported as “
BIN HI LIMIT SW BAD ”.
11) If wet supply rotary switch becomes uncovered there is a timer which must expire before a warning is given. This timer/delay
was called "AUX 1 DELAY",
but is now termed "
WET BIN SW . delay" It is found under the DELAYS key.
12) The time a user has to think about making a change to a timer/setpoint before it automatically proceeds to the next selection
screen has been doubled.
13) Changed the name of delay/timer "
LOW LEVEL TIMER " to " LO LEVEL SWITCH ."
14) Enabled the " START FANS WITH HIGH " switch function. There was previously a screen available to select this function, but
it was never active.
15) The
cool down timer is now set to the reload value of the cool timer whenever any one of the four following shutdowns takes
place:
i) Dry and Hold switch is turned to on state.
ii) Grain falls away from wet bin supply switch.
iii) Storage chamber is full. iv) Dryer is out of grain.
16) Fans Off Delay now defaults to 0 minutes instead of 1 minute and has an upper limit of 5 minutes. This delay can be found
under the “delay” key.
17) The dryer functions the same whether the load switch is in auto or on, but the out of grain timer only times down while the load
switch is in the auto position
and one of the load augers is running.

VERSION: 2.14
REVISED BY: Steve Logue RELEASE DATE: Sept 20, 2002
NOTE: This Version does NOT support Watchdog and the Heater Version MUST be 1.09 not the Watchdog version 1.10.
1) Fixed software so the burner differential could be set to one degree and it would remain there after loss of power.
