Frequently Asked Questions
ZM
305 GTN INBOUND-
OUTBOUND INDICATOR
1. The ZM305 series is comprised of two
dierent products, what are they?
› ZM305 Standard stainless steel IP69K desktop with
multiple built-in weighing applications with IBN display.
› ZM305 GTN Inbound-Outbound stainless steel IP69K
with IBN display.
2. What is an IBN display?
This display technology provides tremendous contrast
between its illuminated digits and surrounding background. It
is used within the automotive industry to improve viewing in
both bright and dimly lit environments.
3. Are the rounded enclosure corners and
modern colored keys standard?
Through market research, customer research, and extensive
application research, the ZM305 indicator series has been
designed using a patented design language (US patent
672,262) to create a common product oering. The design
language consists of colorful easy to read keys as well as
industry leading, easy to clean rounded corners.
4. What power source is required to
operate these indicators?
The indicators can operate from a mains power of 90-264 VAC
(110-240 VAC nominal), 50 or 60 Hz, 12 to 36 VDC or from the
optional external battery pack ZM-BAT.
5. How long will the optional external
battery pack power the scale?
The external optional battery pack ZM-BAT utilizes four D cell
batteries. Fresh batteries will maintain operation of a single
weight sensor system for six hours, or a four weight sensor
system for four hours and one hour with systems with eight
weight sensors. The ZQ-BAT option with auto shuto has
selectable sleep mode choices in the Supervisor menu which
will extend the battery life if enabled.
6. The excitation voltage to the weight sensors is
10 VDC, how long can the cable length (home
run cable) be from the scale to the indicator?
The length of cable is dependent on a number of inuences
including the number of load cells, the quality and gauge of
wire, the cable installation methods (conduit) and any external
sources of electrical noise. The ZM305 will support up to 14 (350
ohm) load cells. When using Avery Weigh-Tronix supplied load
cell cable the maximum recommended length for this would be
500 feet (152 meters).
7. The keys on the front panel have a crisp
snapping response, is this normal?
The indicator’s durable front panel is chemical resistant and the
keys’ tactile feedback is maintained by high quality steel spring
domes.
8. Is the IP69K stainless steel a standard feature?
The ZM305 is enclosed in a stainless steel assembly with a
IP69K certied rating.
9. What does IP69K mean?
IP69K is a worldwide recognized standard which denes the
ingress protection of the enclosure. The ZM305 stainless steel
models are third party IP69K (IEC 60529) certied by FALAB.
Do not be misled by brands that state their products are
designed or equal to IP69K without certication.
10. In addition to the ingress protection IP69K
provides, is there a solution for internal
condensation that may occur when a cold
stainless steel enclosure is subjected to hot
steamy water during a cleaning cycle?
Each stainless steel IP69K enclosure includes a patented air
pressure and temperature equalizing solution.
11. How many weigh sensors does the ZM305 support?
These indicators support up to fourteen 350 ohm weigh
sensors with 10 VDC excitation.
12. How many Truck ID records can be
stored in the indicator database?
The ZM305 GTN database can store up to 1000 Truck records. The
records can be combined between Fleet and In/Out Trucks.
13. What information is stored in a Truck record?
Each truck record can store the truck ID (up to seven numeric
digits), Gross, Tare and Net Totals, number of Transactions, Fleet
Truck Tare weights, and the Inbound time/date and weight of
any unnished Truck In/Out transactions.
