SAFETY NOTICES / 1

SAFETY NOTICES

Safety notices are one of the primary ways to call attention to potential

hazards. An absence of specific alerts does not mean that there are no

safety risks involved.

This Safety Alert Symbol identifies important safety

messages in this manual. When you see this symbol,

carefully read the message that follows. Be alert to

the possibility of personal injury or death.

Use of the word WARNING indicates a potentially hazardous

situation which, if not avoided, could result in death or serious

injury.

Use of the word CAUTION with the Safety Alert Symbol indicates a

potentially hazardous situation which, if not avoided, may result in

minor or moderate injury.

Use of the word CAUTION without the safety alert symbol

indicates a potentially hazardous situation which, if not avoided,

may result in equipment damage.

PRINTER

An optional printer that is RS232 compatible or a USB printer that supports

Printer Control Language (PCL) can connect to the GAC®2500 to print test

data results to a ticket. The ticket can be setup to include the facility name

and address, product, date and time, sample ID, customer ID, grain

calibration date, percent moisture, grain temperature, test weight, and

errors. The data can be automatically printed at the end of each

measurement cycle or manually initiated by pressing the Printer button.

NOTE: After unpacking, visually

inspect for damage occurring

during transit. Save all packing

materials until inspection is

complete. If damage is found,

file a claim with the carrier

immediately and notify your

DICKEY-john sales

representative.

8 / INSTALLATION

The grounding pin on the line cord connects directly to the

GAC®2500 frame. When using an adapter ensure the

grounding wire is connected properly to a good earth ground

to prevent a shock hazard.

GRAIN DRAWER

The unit is equipped with a standard grain drawer with handle. An optional

bottomless grain drawer is available for purchase from DICKEY-john.

OPTIONAL BOTTOMLESS GRAIN DRAWER

Part Number: DRAWEROPGAC2500

A bottomless grain drawer is used with a flow-through work counter that

allows the tested grain samples to fall through to a larger container below.

The size of the hole must be at least equal to the drawer dimension and

located directly beneath the grain sample drawer.

NOTE: Contact DICKEY-john Technical

Support at 1-800-637-3302 for

additional information on grain

drawers.
