Important installer and user information:
A redundant temperature sensing device has been included in this ULT freezer.
This device is a type “T” thermocouple. For convenient access, the thermocou-
ple (Figure 1-3) terminates in an interconnect jack (Figure 1-5) behind the
base front cover. (May be located differently in chests. See Section 1.) It is
strongly recommended that this thermocouple be attached to a redundant 24
hour 7 day monitoring system with alarm capabilities. Connecting the sensor
to a monitoring and alarm system separate from the freezer provides the
utmost in product safety, should the integral system fail.

The Model 5600 Series freezer has remote alarm contacts and analog
output. See Figure 1-2 for the location of the remote alarm contacts. The
remote alarm connector is located in the parts bag provided with the
manual. It must be installed if connecting the freezer to an alarm system.
After installing the wiring from the alarm system to the connector, install
the connector to the freezer microboard and secure with the two screws
provided. The remote alarm provides a NO (normally open) output, a NC
(normally closed) output and COM (common). The contacts will trip on a
power outage, high temperature alarm or low temperature alarm. Figure 1-
8 shows the remote contacts in alarm state.
The analog output function allows the freezer to output signals
representing the temperature of the freezer cabinet. The factory default
setting is 4-20 mA. Refer to Figure 1-9 for output specifications.

IMPORTANT USER INFORMATION
IMPORTANT USER INFORMATION
Caution! Stored product should be protected
by a redundant 24 hour/day monitoring
system with alarm capability. An interconnect
jack and thermocouple are installed
for centralized monitoring should on-board
system fail.

Insert the power cord into the power inlet module. Place the retaining
bracket (P/N 195763) over the connector. Tighten retaining screws to
secure.
Caution See the serial tag on the side of the unit for electrical specifications
or refer to the electrical schematics in this manual. s
The freezer should be operated on a dedicated grounded service. Check the
voltage rating on the serial tag of the unit and compare it with the outlet
voltage. Then, with the power switch turned off, plug the line cord into
the wall outlet.
First turn on the freezer power switch. Then open the lower front door by
grasping the bottom left corner. Locate the battery switch (Figure 1-5) and
turn it to Standby mode ( ). During initial freezer start-up, the system
battery may require charging and the Low Battery message may appear in
message center.
Caution Ensure the battery switch is turned to Standby mode ( ). The
rechargeable batteries require 36 hours to charge at initial start-up. A “Low
Battery” alarm may occur until the batteries are fully charged. Should a
power failure occur during the initial start-up period, the electronics will
have limited operation. s

An access code of 000 is required to access the Settings, Calibrate or
Configuration modes. If the access code is not set at the default ‘000’, a
code must be entered to leave RUN mode. See Section 3 for instructions
on modifying the access code.
Run is the default mode for the freezer. The run mode will display the
cabinet temperature on the temperature display and ‘SYSTEM OK’ on the
message center under normal operating conditions. In addition, this mode
allows display of the following information:
LINE VOLTAGE
COMPENSATED VOLTAGE
HSHX TEMPERATURE (heat exchanger temperature)
This information is scrolled individually by pressing the right arrow key. In
each case, the message center returns to SYSTEM OK in 10 seconds if no
keys are pressed.

Section 2 Calibrate
Once the freezer has stabilized, the control or sample probe may need to be
calibrated. Calibration frequency is dependent on use, ambient conditions
and accuracy required. A good laboratory practice would require at least an
annual calibration check. On new installations, all parameters should be
checked after the stabilization period.
Caution Before making any calibration or adjustments to the unit, it is
imperative that all reference instruments be properly calibrated. s
Plug a type T thermocouple reader into the receptacle located inside the
lower door (see Figure 1-5). Compare the control temperature set point to
the temperature of the measuring device. See Chart 2-1 at the end of this
section for more detail.
1. Press the Mode key until the Calibrate indicator lights.
2. Press the right arrow until “CONT T = -XX.X” appears in the message
center.
3. Press up/down arrow to match the display to calibrated instrument.
4. Press Enter to store calibration.
5. Press the Mode key to return to Run or the right/left arrow to go to
next/previous parameter.
