INTRODUCTION
The MAX digital weight indicator has been specifically designed for mobile
weighing applications. Multiple power inputs, a versatile display, and a weather-
proof enclosure allow for efficient and trouble-free scale operation in any location.
Sophisticated filtering algorithms and display modes offer the best solution
available for vibration issues and dynamic applications such as livestock
weighing.
Built from the ground up with battery-friendly components, the MAX incorporates
Western’s unique PowerMAX operating platform that intelligently identifies when
to supply or conserve power resources. This industry leading power efficiency
stretches battery life to over 500 hours! Designed with the durability,
functionality, and versatility expected from Western, the MAX is truly engineered
for the diversity of the weighing industry.
The following information is for the exclusive use of WESTERN Dealers and
Customers.
Safety
Installation, configuration, and servicing are only to be done by qualified Scale
Service Technicians as authorized by Western.
Power must be disconnected before servicing the unit. Disconnection from the
line voltage is done by disconnecting the mains plug.
This equipment must be connected to a socket-outlet with a protective earthing
connection. The socket outlet shall be installed near the equipment, and shall be
easily accessible.
This equipment is intended for connection to multiple RATED VOLTAGES or
FREQUENCIES. The switchover to the corresponding voltage is done
automatically by the equipment.
Scale Service Technicians handling MAX PCBs must observe
proper electrostatic discharge (ESD) handling procedures.
ATTENTION! Unauthorized installation and service of this unit
may void the warranty.
CAUTION! HIGH VOLTAGES are present inside the MAX
indicator enclosure.

DISPLAY & ANNUNCIATORS
The MAX uses a Liquid Crystal Display (LCD) with an LED backlight. HTN
technology gives the display better contrast over wider viewing angles. LCD
arrow and display annunciators communicate scale status and mode information
to the user.
Weight Display
•6 digits (7 segments each). Up to 3 decimal points.
•Negative weights are indicated by a minus sign (-) on the far left character.
Arrow Annunciators
CENTRE ZERO: The scale is within ±0.2 graduations of TRUE
ZERO.
MOTION: The scale is IN MOTION (the weight is changing).
GROSS: The scale is in GROSS weighing mode.
NET: The scale is in NET weighing mode (a tare weight is stored).
DYNAMIC: The scale is weighing in DYNAMIC mode (if enabled).

Display Annunciators
Scale is weighing in POUNDS.
Scale is weighing in OUNCES.
Scale is weighing in KILOGRAMS.
Scale is weighing in GRAMS.
The weight on the scale is STABLE.
The averaged scale weight has been LOCKED on the
display (only if dynamic weighing is enabled).
The indicator is displaying a PIECE COUNT. Not available at
this time.
The indicator is displaying a SHRINKAGE weight.
Indicates that the BATTERY IS IN USE & BATTERY LIFE
3 segments = Full battery life
2 segments = Med battery life
1 segment = Low battery
0 segments = Change batteries as soon as possible
Flashing = Batteries are too low for indicator to run
Some annunciators may not function the same way in Remote
Display Mode. For more information, see page 16.

KEYPAD & SCALE FUNCTIONS
The MAX indicator utilizes 5 keys for operator interfacing. To maximize indicator
functionality, some keys perform multiple functions.
Press the key: MENU - Cycles through the USER MENU to
access additional Scale Tickets and
functions (See page 13).
Press & hold
the key (2 sec): POWER - Turns the indicator ON and OFF
Press the key: GR/NT - Toggles between GROSS and NET
weighing modes if a tare value is stored.
Press & hold
the key (2 sec): CLEAR - Clears any previously acquired tare
values. When used in Legal for Trade
applications, tares can only be cleared when
GROSS weight is at no load.
Clears Peak Hold (locked weight) values
when Peak Hold function is enabled.

The TARE button may be disabled in Calibration Mode by
Qualified Technicians.
Press the key: TARE - Acquires a tare value from weight on the
scale (Container, Box, etc.).
The indicator will not tare if:
•Scale weight is in MOTION;
•Scale weight is zero, negative or over capacity;
“Err 2” is briefly displayed when one of these
tare errors occurs.
Press & hold
the key (2 sec): CLOCK – Display / Set the time and date. For
more information, see Time & Date (page 15).
ZERO: Sets the weight display to ZERO.
The indicator will not zero if:
•Scale weight exceeds the allowed ZERO RANGE;
•Scale weight is in MOTION or over capacity;
“Err 4” is briefly displayed when one of these zero
errors occurs.
Press the key: PRINT - Transmits a scale ticket or data string.
NOTE: If multiple tickets are programmed, Ticket 1 is
always assigned to the PRINT key.
Press & hold
the key (2 sec): UNITS - Toggles between Primary, Secondary and
Tertiary Weighing Units (if enabled).
Alternate Units may be selected or disabled in
Calibration Mode by Qualified Technicians.
In Canadian Legal for Trade applications, previous tare weights
must be cleared before a new tare weight can be acquired.

INSTALLATION
Pre-Installation
It is always good practice to verify that your Western MAX indicator is complete
and undamaged upon receipt.
•Check over packaging for any signs of damage.
•Remove the MAX from protective packaging and check for damage.
•Verify that the box includes the MAX indicator complete with:
oUser Manual;
oMounting bracket and thumb screws;
oNote: Batteries not included.
Mounting Instructions
1. The MAX can be mounted to horizontal or vertical surfaces using the
mounting bracket.
2. Ensure that mounting structures (walls, posts, etc.) will bear the weight of
the indicator (Approx. 3 kg / 7 lb with batteries).
3. Use proper hardware, including wall anchors where necessary, when
mounting the bracket and indicator.
Plugging In
1. Plug the AC power cord into a power outlet.
2. Installers must take proper steps to prevent noise, static, or other power
problems.
ATTENTION! In noisy industrial environments, power-
conditioning filters are a requirement to ensure a fail-safe
operation under all conditions. Indicators should not share AC
power with electrical motors and switchgear. Consult the site
engineer for clean AC power.
CAUTION! HIGH VOLTAGE! Only trained personnel should
access any internal wiring and/or components.
