Digital Weight Indicator
Reference Manual
Issue AD
Preface
We at GSE wish to thank you for selecting the Agrifeed 5500 Digital
Weight Indicator for your weighing needs. The Agrifeed 5500 continues
the GSE tradition of Excellence in Weighing Technology. When properly
installed and maintained, the Agrifeed 5500 will provide many years of
reliable, accurate performance. Please read the sections on installation
and setup before proceeding with installation.
Warning
The Agrifeed 5500 contains components which could be damaged by
Electrostatic Discharge (ESD) if serviced improperly. Use proper ESD
precautions (wear a wrist strap connected to ground, use grounded work
stations, etc.) when opening the enclosure. ALWAYS unplug the
Agrifeed 5500 when opening the enclosure. Installation and servicing of
the Agrifeed 5500 should be performed by authorized and qualified
service personnel only!
It is important to ensure that the indicator stand is grounded to the truck
frame or the truck battery. If the indicator stand cannot be secured
directly to the truck frame, then it is necessary to provide a grounding
strap from the stand to the frame. Failure to ground the stand can result
in the buildup of a static charge that could damage electrical components
within the indicator, thus voiding the warranty. The indicator power
cable should be run directly to the positive and negative terminals of the
battery.

The Agrifeed 5500 makes extensive use of the display and keypad. The
display and keypad perform different functions in the weigh mode, setup
mode and help mode.
Upon power-up, the back-light and all pixels illuminate momentarily for
a display test. The indicator then displays the Agrifeed GSE Model 5500
revision screen followed by the Operator ID? prompt (see Figure 1).
Key in the operator ID number and press [ENTER], or press only
[ENTER] to bypass the prompt. The operator ID will be recorded with
each load or unload transaction saved in the history database.

Section 2: Installation
2.1 Unpacking
When unpacking your new Agrifeed 5500 Indicator, do not discard any
packing material until you are sure you have all the components needed
for your installation. Small bags are included containing parts that may
be required for a complete installation.
2.2 Mounting
This section contains information necessary for proper installation of the
Agrifeed 5500. The standard enclosure is designed to allow wiring
without opening the enclosure. All wiring is accessible through bottom
connectors (see Figure 6: Agrifeed 5500 Connector Label).
2.2.1 Environmental
The Agrifeed 5500 Stainless Steel enclosure is designed to NEMA 4X
(IP66) type specifications.
2.2.2 Rear Panel Mounting
The standard enclosure is designed to attach to an existing stand for
mounting. Note that the stand shown in Figure 3 is not supplied by GSE.
Figure 3: Rear Panel Mounting Screws
7
2.2.3 Swivel Mounting (Optional)
The optional swivel mounting bracket allows the enclosure to be securely
fastened to another surface. The bracket is attached to the indicator with
four thumbscrews two of which are used to lock the swivel for optimal
viewing angle.
2.3 Legal for Trade
Most legal-for-trade installations will require the Agrifeed 5500 to be
sealed. A sealed indicator cannot be accessed for setup or calibration
changes without breaking a physical seal or incrementing an event
counter, thus providing evidence of tampering.
The Agrifeed 5500 has two types of sealing provisions, a physical seal
and a three event audit trail counter. Check with your local weights and
measures authority to determine your requirements.
2.3.1 Physical Seal
The most common sealing method is a lead-wire seal. Before applying a
wire seal, move the program jumper to the ‘NO’ position as shown in
Figure 4. Doing this will prevent access to the Setup and Calibration
Modes.
Figure 4: Program Jumper
8
The seal will pass through two back panel screws as shown in Figure 5.
Figure 5: Legal for Trade Sealing Method
2.3.2 Audit Trail
Three separate incrementing, non-resetable audit trail parameters are
used to indicate changes to various parameters, P60201 – OIML, P60203
– Calibration , and P60204 – Setup. An audit trail counter will increment
only once upon exiting the Setup Mode and saving changes regardless of
how many settings were changed.
With the indicator off, press and hold [CLR] key and turn power on.
Continue to hold [CLR] until "Macro Disbl" is displayed. Key in
"60203" and press [NET/GROSS] to view the calibration event counter,
or key in "60204" and press [NET/GROSS] to view the configuration
event counter. To return to the normal weigh mode from either parameter
"60203" or "60204", press the [ZERO] key.
2.4 Wiring
A description of all wiring terminals is included on the bottom label of
the enclosure as shown in Figure 6.
Figure 6: Agrifeed 5500 Connector Label
9
2.4.1 Load Cell Connection
A high quality cable with braided shield is recommended. Use a fourconductor, 16 to 24 AWG stranded wire cable for load cell or summing
box connections.
2.4.2 Printer Port Connection
The printer port is a RS232 bi-directional serial port that can be
connected to a printer or computer. Use the custom print formats
described in section 3.3.3 to configure the printer port output.
When making the printer port connections, consideration should be given
to the communication protocol. Refer to Table 3 in order to determine
proper wiring for the printer port.
The Comm port is a RS232 bi-directional serial port that can be
connected to a computer or any other serial device. This port can be used
for bi-directional communications with a serial device, through an RF
link or data logger, for recipe and transaction data exchange.
Before connecting to the comm port, consideration should be given to the
communication protocol. To determine proper wiring to the comm port,
refer to Table 4.
A remote key may be connected to the Agrifeed 5500 to provide remote
activation of TARE, ZERO, PRINT/ADVANCE and PRINT & TARE
functions.
The connection for the remote key input is between pin 4 of the power
connector and ground (pin 2). A two-conductor cable between 28 and 20
AWG is recommended. The input requires a contact closure from a
push-button switch, a mechanical relay contact or other such device.
Do NOT apply an external voltage to the remote key terminal! Only a
contact closure is required to activate the remote key input.
Figure 7: Remote Key Connection
The open circuit voltage across the Remote Key pins is +5 VDC. A
closed switch will conduct about 0.25 mA. Therefore, a low-voltage
switch with gold-plated or mercury wetted contacts is recommended.
The input may also be activated remotely with a RF remote key. A
minimum contact duration of 100 ms is required. Once invoked, the
selected remote key operation will not repeat until the contact is released
and closed again.
2.4.5 Power Connection
The Agrifeed 5500 is powered by an external 10.5-16 VDC power
source. The power supply should have a minimum current rating of
800mA. Table 5 shows the power connector pin locations.

2.4.6 Alarm Out Connection
This connection is used in conjunction with the [MIX TIMER] key.
When the mix timer is not active pin 3 has a floating output. When the
mix timer is active (i.e. counting down) pin 3 is pulled high to the supply
voltage.
Example:
The indicator power is supplied by a truck battery, typically 13.8
volts. The output from pin 3 is 13.8 volts when the mix timer is
active.
