GSI cannot warrant any roof damages due to excessive
vacuum or internal pressure caused by fans or other air
moving systems. Adequate ventilation and/or "makeup
air" devices should be provided for all powered air han-
dling systems. GSI does not recommend the use of down-
ward flow systems (suction). Severe roof structural dam-
age can result from any blockage of air passages. Run-
ning of fans during certain high humidity/cold weather
conditions can cause freezing over of air exhaust or in-
take ports.

TING PROCEDURE
There are three possible configuration modes for
the Top Dry.
1. Stand alone heater control. Master control is
located on fan/heater and no other control is neces-
sary. Running fan/heater in this mode requires
climbingupto fan/heater to start unit and adjust con-
trols.
2. Econo control center. In this case the control is
located up on the fan/heater and has been pre-pro-
grammed. Power is then applied from a switch be-
low. The start switch is a momentary switch that is
attached to J7-7 connector. The dryer is started by
depressing that momentary switch. Note, that in this
mode, the display is remote, therefore error condi-
tions will shut the dryer down but cannot be viewed
unless you climb up and look at the display.
Limit switches are checked upon power up. The
controlchecksallthe limit switches. If a limit switch
has become open circuit the control displays which
limit is open circuit. The control will not operate
with a limit switch error. The fan will not turn on
with an error condition. There is no way to bypass
an error condition. It must be fixed (see errors page
22). The air switch is also checked on power up.
The air switch should indicate no airflow. This is
neces-sary to check the function of the air-

to program the master, view errors and start the

extension of the master.

not be bypassed since, in the Top Dry system, the
fan is controlled by the heater control.

The limits are continuously checked during
the off mode. A limit switch open or any other
error condition will cause the display to show the
limit or error condition. When the dryer is not
running, if the limit or error condition is corrected,
the LCD returns to its normal display. This is not
the case with an error or limit condition during
the drying operation. This causes the display to
lock up in the error display mode, the dryer
stops running, and the error must be corrected.

limit opens or an error condition occurs during dry-
ing, the control will lockup in the error display
mode. Power must be shut off and back on to clear
the error condition, even when the error or limit that
caused the shut down has been corrected.
The main display shows either dry run time
(lower left cursor), cool down time (lower 2nd
from left cursor), plenum (lower 2nd from right
cursor) or grain temperature (lower right cursor).
The "mode select" (fan bypass) is used to select
the mode to be displayed. Note, that the cursors
do not flash when in the normal display. They do
flash when in the program mode (see page 18).
The dry and cool down shown on the display is
the amount of time remaining in the dry or cool pe-
riod. Note, that if unit is in the dry time period,
youcannotview the cool time remaining,sincethe
unit is not in the cool period. However, the cool
period may be altered or viewed by entering the pro-
gram mode. The same is true if the heater control is
in the cool period.You cannot view the dry run time,
since that time has already expired.

Wrong voltage.
Dip switch #5 is
the voltage se-
lector switch. If
dip switch #5 in
"ON" that se-
lects 240 VAC.
If the unit has
only 120 VAC
applied, error 12
will show up. If
dip switch #5
is"OFF" that se-
lects 120 VAC. If
the unit has 240
VAC applied er-
ror 12 will show
up.
This is im-
portant because
if the fan heater
is set up at GSI
for 120 VAC and
the customer
connects to 240
VAC the heater
control will work,
but if allowed to
operate the so-
lenoids will have
240 VAC applied
to them which
will damage so-
lenoids.

(Errors 9 through 11 are displayed only if multiple heat-
ers are tied together through serial link).
Note: Temperature sensor connection-the temperature
sensor (bolt) must always be connected to the master.
In the case of the Top Dry, both temperature sensors
must be connected to the master (unit at the top). Top
Dry grain temperature input is connected to J7 pins 14
and 18.
through the serial link. If the master cannot com-
municate with a slave controller, the master will dis-
play "SLA" on the main display and the "RX" "TX"
