Graphical Display
The Twin Guard Series™ is managed by
an integrated microprocessor controller
with LCD information center to simplify
all freezer functions. Uniform ultra-low
temperature is achieved through a
combination of performance systems
supervised by the controller complete
with alarm, programming and diagnostic
protocols.
• The control panel is center mounted
in the outer door for easy, eye-level
access.
• Control and information center
includes an intuitive pop-up menu,
high resolution LCD for inputs, out-
puts and performance at-a-glance.
• Multi-point data logging offers a
graphical display for temperature
verification at-a-glance.
• Precise logic systems control and
adjust to temperature setpoints and
alarm parameters.
• Setpoint, alarm and programmable
inputs are established through pop-
up menus and function keys.
• Logged parameters can be exported
to remote databases, off-site alarm
or data capture systems through
optional communications board
module for compliance monitoring.
An optional PC interface permits
remote transmission; see
Accessories.
• Standard parameters are factory-set
for quick start-up, and all parameters
can be changed as required.
• A remote alarm terminal mounted at
the side of the cabinet can be con-
nected to an external alarm system.
• Tactile feedback, touch pad data
shift and entry keys simplify opera-
tion. All setpoint and alarm functions
are entered through an intuitive
keypad with visual prompts.

ing compressors and fan motors are
background monitored for perfor-
mance.

warnings are automatically dis-
played with audible warnings when
necessary.
