The Model 350 and Model 355 indicators are available with either a six digit, 7-segment green LED display,
a six digit, 7-segment black LCD display or a 7-segment backlit LCD display. The Model 350 and Model 355
will display alphanumeric data, but due to the nature of 7-segment LEDs/LCD and the limitation of six digits,
some information is abbreviated.
All segments and annunciators are illuminated for a brief display test upon power up. The current gross
weight is then displayed in default units.
LED DISPLAY
The LED display is a six digit, 7-segment bright green LED screen with 12 annunciators to show
weight and status information. The SP1, SP2, and SP3 annunciators are red, green, and yellow. Also
there is an annunciator for a third unit under kg. Place the third unit label above the third annunciator
(the third unit is available on both the LED and LCD displays). See page 53 for third unit setup.

Wiring
Wiring a load cell or communication port is simple on both the die cast and stainless steel models. Refer to
the information in this section for more details.
STAINLESS STEEL MODEL 350/355
The stainless steel models must be wired through the strain reliefs located on the bottom or rear of the
enclosure and connected to the main board. Refer to Figure 9 and Figure 10.

DIE CAST MODEL 350
A description of all wiring terminals is included on the bottom label of the zinc die cast enclosure as shown in
Figure 11.
Figure 11: Model 350 Zinc Die Cast Enclosure Wiring Label
LOAD CELL CONNECTIONS
A high quality braided shield cable with 16 to 24 AWG stranded wire is recommended for load cell or
summing box connections. Secure the cable by the cable tie on the die cast model, or route it through the
strain relief supplied on the back of the internal power supply models (see Figure 12). Either four or six
conductor cables can be used.
12
350/355 Technical Reference
Do not tin the ends of the load cell wire! A terminal connection free from the effects of vibration
and oxidation can be assured only if the load cell terminals securely grip a bare, stranded wire.
When using four conductor cables, (+ Excitation) must be connected together with (+ Sense), and (Excitation) must be connected together with (- Sense) on the Model 350 die cast. Sense jumpers are
standard on the Model 350/355 Stainless Steel (E3 and E4). Utilizing the (+) and (-) Sense leads of six
conductor cables provides compensation for variations in the excitation voltage due to resistance changes in
the cable.

Figure 13: Model 350/355 Stainless Steel Load Cell Connector (J10)
SERIAL PORT CONNECTIONS
Before connecting to the serial port, consideration should be given to the communication protocol and to any
remote key requirements. For information on remote key operation, refer to Remote Key Operation on page
97. Use Table 1: Serial Port Connections to determine proper wiring to the communication port.
Communication connections are made through the DB9 male connector on the rear of the enclosure or a
pigtailed cable through a strain relief (internal power supply model on J6 comm connector). The cable
should be 20 to 28 AWG with a braided or foil shield for either model type. For maximum noise immunity on
the die cast model, use a mating DB9 connector with a metal hood and a braided shield cable. Ensure that
the braid makes good connection with the hood. The maximum recommended cable length is 50 feet (15
13
Chapter 2
meters). However, much longer connections are possible if using a properly shielded, low-capacitance
cable.

REMOTE KEY CONNECTION
A remote key may be connected to the Model 350/355 communication port to provide remote activation of
print, tare, or zero functions.
The connection for the remote key input is between pin 1 and pin 6 of the DB9 communication port
connector (see Figure 15 for die cast, Figure 14 for stainless). A two-conductor shielded cable between 28
and 20 AWG is recommended. The input requires a contact closure from a push-button switch, a ‘dry’ relay
contact, a photo-eye, and a proximity sensor or other such device. A closure initiates the operation specified
at P800.
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 contacts is recommended. A Mercury-wetted switch will
also work well. 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.
Do not apply an external voltage to remote key terminals! Only a contact closure is
required to activate the remote key input.

To install the swivel bracket:
1. Unpack the Swivel Bracket option.
Be sure that all parts shown in Figure 20 are accounted for.
2. Remove the two plastic Heyco plugs.
The plugs are located in the threaded bracket mounting holes on either side of the indicator. Be careful not
to scratch the finish of the indicator when removing these plugs.
Chapter 3
3. Place the two spacers against the bracket and then insert the thumb screws.
The spacer and bracket holes should align with the bracket mounting holes on either side of the enclosure.
PANEL MOUNT KIT
The Panel Mount Kit provides an easy way to mount the indicator into new or existing cabinetry. See Figure
21 for detailed instructions on panel mounting the Model 350 die cast. See also NTEP Panel Mount
Requirements on page 123 for additional panel mounting NTEP requirements.
Figure 21: Model 350 Panel Mount Installation (Die Cast Model)
18
350/355 Technical Reference
To install the Model 350 Panel Mount Kit:
1. Unpack the Panel Mount Kit.
Be sure that all parts shown in Figure 21 are accounted for.
2. Remove the two plastic Heyco plugs.
The plugs are located in the threaded bracket mounting holes on either side of the indicator. Be careful not
to scratch the finish of the indicator when removing these plugs.
3. Place the adhesive gasket around the panel cutout.
This step is optional. The gasket should be adhered onto the outside of the panel and centered around the
cutout.
4. Place the Model 350 through the panel cutout.
This step may require a second person to hold the indicator in place. The indicator should be centered
inside the cutout.
5. Using two small screws and star washers, attach the two panel mount brackets. The center holes of the
brackets should align with the threaded bracket mounting holes on either side of the indicator. The two
brackets should angle away from the indicator. Apply pressure on the mounting brackets in the directions
shown in Figure 21. This will ensure the indicator is drawn firmly against the panel.
6. Using four long screws and four lock-nuts, secure the indicator to the panel. Thread the lock-nuts onto the
screws so that they will not interfere with tightening the screws into the threaded bracket holes. Evenly
tighten the four screws until they are snug. Do not over-tighten. Now thread the lock-nuts down until they
are snug against the bracket.
7. Drill 1/16 (0.0625) diameter pilot hole on the front of the enclosure for the serial number label.
8. Add the serial number to the label.
9. Install the label by tapping the pins through the label into the front enclosure.
Analog Card Connections
The 16-bit electrically-isolated analog output module provides a highly accurate analog signal, proportional
to weight. This signal can be used for interfacing to PLCs, chart recorders, and other such devices.
See Analog Output Setup on page 67 for analog output software configuration details.
The Model 350/355 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.
High voltages may exist within the enclosure! To prevent the risk of electrical shock, ALWAYS
unplug the Model 350/355 when opening the enclosure. Installation and servicing of the Model
350/355 should be performed by authorized and qualified service personnel only.
Never connect or disconnect option board cables while the indicator is powered. Doing so may
result in circuit board damage.
19
To install the Analog Output Module (350 die cast model):
1. Open the indicator. Remove the four screws from the back of the unit. It may
help to remove the swivel bracket, if installed.
2. Place the back of the indicator, open side down, on a firm surface. Using a
hammer and screwdriver, remove the appropriate knock-out.
It helps to place the screwdriver tip on the knockout pad, rather than in the
groove. The knock-outs do not require much force to remove. If only
installing one option, the left knock-out (as viewed from the rear) should be
removed. A small file may be used to remove any burrs.
3. Flip the back cover over and place the Analog Output Module, component
side down, over the four mounting holes. Install four 10mm screws to a
minimum of 8 in/lb of torque.
Chapter 3
Be sure the cable is already attached before installing the card. Also, be sure
the cable is attached to the left-most connector (as viewed from the
component side of the option board). The second connector is for ‘daisychaining’ another option card. The screws used to mount the option card are
self-tapping and will require added torque when first installed.
4. Attach the loose end of the cable to the serial I/O connector (J7) on the main
board or the open connector of a previously installed option card.
J7 is a 10-pin polarized connector. Be sure the cable is not twisted when installed. If this is a second option
card, route the cable to the open connector of the first option card.
5. Reinstall the back cover. Tighten the four screws to a minimum of 8 in/lb torque.
Be sure to avoid ‘pinching’ the cable between the housing halves. Affix all appropriate labels to the back of
the indicator.
To install the Analog Output Module without mounting bracket (Model 350/355 Stainless):
If only one option is being installed in a fiber-optic hub indicator use the following instructions. If two
options are being installed along with a fiber-optic option an option mounting plate is required. Refer
to page 27 for installation instructions.
1. Open the indicator.
Remove the eight screws from the back of the unit.
2. Locate the option mounting holes by lining up the option card with the four holes to the left of the power
supply section on the main board.
