Configuration mode. The “Relay” column shows whether each alarm is of sufficient priority to
warrant activating the remote alarm contacts.
Note that the remote alarm contacts will always have a 30 minute delay to
activate to allow time for on-site personnel to react to and resolve the alarm
condition.
Upon the occurrence of any alarm, the top line of the message center display will list the alarm
message as shown in the list. In the case of multiple alarm conditions, the display will show
each alarm message on the top line in a repeating sequence on three second intervals. The
alarms will appear on the message center ONLY when in RUN mode. If the operator changes to
a different mode, the alarm LED and the audible alarm will remain active, but the message
center top line will display whatever the normal message would be in that mode.

Alarm Criteria
HIGH TEMP ALARM – Activates when the control probe temperature is at or above the
high temp alarm level as stored in memory for more than 1 minute. (Not Cold Enough)
LOW TEMP ALARM - Activates when the control probe temperature is at or below the low
temp alarm level as stored in memory for more than 1 minute. (Too Cold)
DOOR OPEN – Activates when the door is sensed open for more than 1 minute. Note that
the door sensor is an input to the main control board and its status is to be part of the
regular communication from the main control board to the display board.
AC LINE FAILURE – Activates when the input line voltage falls below 80 VAC for 115 V
unit or 160 VAC for 230 V unit for more than 10 seconds. This alarm will override and
cancel the “LOW LINE VOLTAGE” alarm, so that both alarms are not active at the same
time.
POWER FAILURE 1 – Activates when the input line voltage falls below 80 VAC for 115 V
unit or 160 VAC for 230 V unit for more than 10 seconds. This alarm will override and
cancel the “LOW LINE VOLTAGE” alarm, so that both alarms are not active at the same
time.
POWER FAILURE 2 – Activates when the 12 VDC on the main control board falls below
11.0 VDC for more than 2 seconds and the AC line voltage does not fail.
POWER FAILURE 3 – Identical to POWER FAILURE 2, except the 12 VDC on the main
control board recovers to more than 11.0 VDC. The control logic will return to operating
the main control board on the 12 VDC power supply rather than on battery backup power.
Operating the main control board on battery backup power will eventually drain the
battery output to 10.5 V and the compressors will shut off.

11
Part number 21729, Rev 4
HIGH AMBIENT TEMP – Activates when the ambient temp probe reading is above 36 C.
LOW BATTERY – Activates when the result of a battery test returns a reading of less than
11.0 VDC.
H S SYSTEM FAILURE – Activates when the high stage heat exchanger probe is unable to
reach at least -33 C after running the high stage compressor for 30 minutes.
L S SYSTEM FAILURE – Activates when the high stage heat exchanger probe reaches a
reading of -55 C or below.
AIR FLOW PROBLEM – Activates when a calculation shows that the difference between
the ambient temperature and the condenser temperature probes is greater than 10 C.
LOW LINE VOLTAGE – Activates when the incoming AC power voltage is below 90 VAC
on a 115 V unit or 180 VAC on a 230 V unit for more than 1 minute.
HIGH LINE VOLTAGE – Activates when the incoming AC power voltage is above 135 VAC
on a 115 V unit or 265 VAC on a 230 V unit for more than 1 minute.
PROBE FAILURE (Control, Heat Exchanger, Condenser, Ambient, Sample) – Activates
when either of the following conditions is detected on this probe: A resistance value over
250 ohms, indicating an open sensor, or a reading below 20 ohms, indicating a shorted
sensor. The same criteria will apply to the remaining probe failure alarms.
PROBE UNPLUGGED (Control, Heat Exchanger, Condenser, Ambient and Sample) –
Each probe has a two-pin logic control as part of its connector, which will be used to detect
that the sensor is properly connected. This alarm shows that the system detected this
probe is not connected. This same description applies to all probes.
FAILED BATTERY TEST – Activates when the result of a battery test returns a reading of
bad battery.
INITIALIZING
If the display board is unable to initialize properly, the message center will not display any
valid information. This will serve as the indication of a display board initialization
problem. If the main board fails to initialize properly, it will not be able to communicate
with the display board and the display board will report a communication problem, as
described elsewhere.
Door Open
A door open message is displayed in the message center whenever the door is opened. If
the door remains open for more than 1 minute, an audible alarm will sound, subject to
normal silence and ring back functions. If the door remains open continuously for 30
minutes, the remote alarm contacts will activate.

Contacts and communications
ONLY Authorized, trained electricians should attempt any connection
behind the service panels!
Remote alarm contacts
The Remote Alarm provides a NO (normally open) output, a NC (normally closed) output, and a
Common. The Schematic below represents the alarm state and wire colors. The remote alarm
terminal block is located in the base area of the unit, to the left of the electronic enclosure.
Note:
1) The Remote Alarm contacts will have a 30 minute delay before they are tripped.
2) Always double check the continuity of the NO and NC contacts.
3) This procedure is for the Alarm only. 24 VDC (User supplied)
R= 250 Ω
A 4-20mA signal is available. Connect the circuit to positions 1 and 2 as shown above. Monitor
the DC voltage across a 250 Ω resistor. Remove the galvaneal access cover on the rear of the
ULT to gain access to a Type T thermocouple that can be used to monitor the chamber
temperature. Connect the thermocouple to a temperature reading device to view the chamber
temperature. The dc voltage drop across the resistor corresponds to the chamber temperature
(deg C) and should match the temperature on the display.

14
Part number 21729, Rev 4
Using a 250 Ω resistor, the voltage drop across the resistor varies with temperature per the
following equation.
Temp (C) = - 34.75 (Vdrop) + 74.75

Maintenance procedures
Air filter
In most laboratory conditions, the air filter should be inspected monthly and cleaned once every
three months. Press the top of the filter cover to release the catch. The door will swing forward
allowing easy access to the washable pre-filter.
Condenser
Anytime that the air filter is removed for cleaning, the condenser fins and coils should be
inspected for dust that impedes the flow of air over the coils. Such dust should be removed with
a vacuum cleaner. The fins on the heat exchanger are very delicate and are easily bent, so be sure
to avoid placing any pressure or impact on the fins while cleaning.

15
Part number 21729, Rev 4
Annual calibration
The control temperature probe should be calibrated once a year. This procedure is described in
the Maintenance Procedures chapter under Calibration.
Battery replacement
Warning! Only authorized, trained electricians should attempt any access behind
the service panels!
The battery is located in the lower left-hand (handle side) corner of the compressor
compartment. It may be accessed by either removing the front or left-side cover panel. The
battery is secured with two carriage bolts, but it is only necessary to loosen one bolt to remove
the battery.
Be sure to disconnect the leads from the control box before removing the battery.
Door gasket and vacuum relief port
Any time that dirt or frost accumulation prevents the door from closing properly, the gasket
should be cleaned with a soft cloth. As a general rule, a minimum of once a month is
recommended.
When the door gasket is operating as designed, the only means of pressure equalization for the
chamber is the vacuum relief port behind the control panel. The vacuum relief port is equipped
with a built-in heater to reduce frost accumulation, but some frost can accumulate behind the
port on the freezer door. It is important to make a visual check for such accumulation whenever
the door is opened and remove any accumulation found.
Defrost
1. Switch off the unit breaker switch and disconnect the freezer from power.
DISCONNECT battery to avoid deep discharge. To disable the battery, scroll to the
CONFIGURE MODE and press ENTER. Scroll to BATTERY BACK-UP ON, and press
ENTER
Use the UP and DOWN keys to change to OFF, then press ENTER. Upon restart, this
configuration will automatically revert to the ON setting

16
Part number 21729, Rev 4
2. Empty the freezer of contents and transfer them to another freezer. Leave the inner
doors open.
3. Place moisture absorbing material such as paper or cotton towels in the bottom of the
freezer and on the floor in front of the freezer.
4. Allow frost to melt and loosen. The lose frost can be removed carefully in order to move
the process along more rapidly.
5. Once the freezer is free of frost, use a mild non-chloride cleaning agent, rinsing with
water.
6. Close doors and restore power.
7. Depending upon your temperature set point, storage temperature should be fully
restored in 8 to 12 hours.
Calibration
This procedure allows the temperature readout on the control panel to be adjusted to match
your temperature standard. The calibration allows for a +/-5°C adjustment to “offset” only.
There is no adjustment for “slope” or “span” available through the control panel.
1. Install reference temperature probe next to the control probe located on the interior of the
freezer. The reference probe should be calibrated and traceable to a known standard such as
NIST. The reference probe has to be installed through the access panel on the rear of the unit.
This is best accomplished when the freezer is at room temperature.
2. Turn the freezer on and allow the unit to pull down and cycle at the desired set point, or use
the default set point of -80 C.
3. Navigate to the calibration mode through the control panel, and access the calibration menu.
Scroll through the menu until “Control Probe” is reached. Press Enter to access the menu for
control probe calibration.
4. Using the Up/Down Arrows, adjust the temperature displayed next to “Control Probe” to
match the temperature readout from the reference temperature probe. The temperature is
displayed in tenths of a degree. Then Press Enter to accept the calibration for the control probe.
Note1: The large temperature display may change value when you press Enter, depending on
how much calibration is required.
Note2: The maximum calibration on the temperature probes is +/- 5 C. If further calibration is
required, contact the technical service department for assistance.
