SAFETY

Series 2000 Top Dry Heater Control

Heater Operation

Thank you for choosing a GSI product. It is de­signed to give excellent performance and service
for many years.

This manual describes the operation of the
Series 2000 Top Dry Heater Control Unit. Dif­ferent models are offered, including a 36" diam­eter and a 42" diameter, with a choice of horse­power available on the fan motor.

The principal concern of the GSI Group, Inc.
("GSI") is your safety and the safety of others asso­ciated with grain handling equipment. This manual

is written to help you understand safe operating pro­cedures, and some of the problems that may be en­countered by the operator or other personnel.

As owner and/or operator, it is your respons-

ibility to know what requirements, hazards and
precautions exist, and to inform all personnel as­sociated with the equipment, or who are in the
heater area. Avoid any alterations to the equip­ment. Such alterations may produce a very dan­gerous situation, where serious injury or death
may occur.

Roof Damage Warning

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.

The GSI Group, Inc. recommends
contacting your local power company,
and having a representative survey your
installation so the wiring is compatible
with their system, and adequate power
is supplied to your unit.

Safety decals should be read and
understood by all people in the grain
handling area. The bottom right de­cal should be present on the inside
bin door cover of the two ring door,
24" porthole door cover and the roof
manway cover.

If a decal is damaged or is miss­ing contact:

OPERATING PROCEDURE

The control panel of the Top Dry heater unit.

Series 2000 Top Dry Heater Control

Setup And Configuration

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 neces­sary. Running fan/heater in this mode requires
climbing up to fan/heater to start unit and adjust con­trols.

2. Econo control center. In this case the control is
located up on the fan/heater and has been pre-pro­grammed. Power is then applied from a switch be­low. 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 condi­tions will shut the dryer down but cannot be viewed
unless you climb up and look at the display.

Power Up

Limit switches are checked upon power up. The
control checks all the 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 air­flow switch. The air switch error on power up can­not be bypassed since, in the Top Dry system, the
fan is controlled by the heater control.

If multiple heaters are tied together, and the
master detects that the slaves fan is on (the air switch
stuck?), the master will lock up displaying "SLA
ERROR".

3. Manual control center. In this case the master
control is up on top where all the sensors and limits
are attached. The remote display below is attached
via a serial 2 wire link. The remote display is used
to program the master, view errors and start the
dryer. In essence, the remote display is just a slave
extension of the master.

Normal Operating Displays

Heater Not Running

The main display shows either dry 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"

switch (fan bypass) is used to select the mode to be
