Power: The ULT requires a dedicated power outlet and circuit breaker: 20-amp circuit for 115V models and 15amp circuit for 230V models.

Installation & Start-Up

NOTICE!
READ THIS MANUAL
It is necessary to read and understand this instruction manual because failure to do so may result in (1) substandard performance of your freezer, (2) damage to your freezer and stored items and (3) possible injury to operating personnel.
Placement clearance: The freezer must have a clearance of 5” in the rear and 6” on each side so that enough air circulation is maintained for the removal of exchange heat.

Start-up: Plug the ULT into power and engage the power switch/breaker located above the power cord. The freezer will start, and the control panel will illuminate in the default status with the words SYSTEM NORMAL in the message line, which is the top line of the control display.
The other lines will display available operating modes. You will note a pointer (˃) on the third line.
The third line is always the active line, which means that you will enter that mode or menu by pressing ENTER.

The default status:

Control overview

The SYSTEM NORMAL display is a monitoring and access screen from which you may enter any of the 4 control modes:

CONFIGURE CALIBRATE RUN SETTINGS
The default setting will be sufficient for many hours while your freezer cools. You may familiarize yourself with the control by setting the time, the date, and perhaps setting an access code (numerical password).
Keys: The ENTER key serves to (1) accept menu selections and value changes and (2) advance the active value through a row of values. The BACK key permits you to scroll back through the values or menu.

The UP and DOWN keys permit you to make numeric steps in settings and selections in the menu Warning lights are provided for Voltage boost (which means you should speak to your maintenance department about low line voltage).
The Low battery warning light indicates that you need to replace the battery, the procedure for which is explained in the chapter on Maintenance.
Alarms: Your freezer is protected with 21 alarm monitors. In the event of an alarm, an ALARM MESSAGE will appear in the message line at the top of the screen and an alarm will sound.
Consult the chapter on Alarms in this manual

The alarms that may be set by the user are:
HIGH TEMP ALARM
LOW TEMP ALARM

Setting security access code (optional)
When delivered, the freezer has the password security value in the OFF setting. This means that access to modes and settings other than RUN can be addressed.
If you want to restrict access to all menus other than the RUN menu, which is a read-only menu, then you may activate the password security (PASSWRD SECURITY) by switching it to the ON setting. This setting resides in the CONFIGURE menu.
Once you activate password security, you will automatically acquire the factory default password, which is a four-digit numerical code.

Default access code: 1 2 3 4
You may change the code itself by addressing the SETTINGS menu.
Please note the two menus on the right and remember that the choice of whether a code is needed is made in the CONFIGURE menu; but the code itself is edited in the SETTINGS menu.

Setting security access ON of OFF

1. Navigate to the CONFIGURE mode on the SYSTEM level menu, and then press ENTER.
   • This will take you to the CONFIGURE menu.
   • Scroll down to PASSWRD SECURITY OFF (the current status.)

2. Use the UP and DOWN keys to change from PASSWRD SECURITY OFF to PASSWRD SECURITY ON and press ENTER.

3. You have now activated password protection

4. Press BACK to return to the system level menu.Once you have activated PASSWRD SECURITY ON, the following window will appear when an operator requests access to any menu except the RUN menu:

Changing the password

1. The password (access code) is only required when the security setting is ON.
2. Navigate to the SETTINGS mode line, and press ENTER 2 Scroll to the SET ACC CODE, and press ENTER
3. Set the access code by using the UP and DOWN keys to change the value of each digit and using the ENTER key to move to the next value. You may also use the BACK key to move back through the digits.

Control menus

Note that the RUN mode provides a “view only” menu in which you can verify settings. This is the normal mode of operation for the freezer. To make changes in the settings themselves, you must move to one of the other operation modes, CALIBRATE, CONFIGURE, or SETTINGS.

Operating modes and mode menus

Alarms

A series of alarms monitor the various operating conditions of the freezer. These alarms are presented differently depending on the severity of the alarm condition.
The table below lists these alarms and shows the method of notification. The “Message” column shows what message will be displayed in the message center. The “Audible” column shows if the audible device is activatedThe “Ringback” column indicates if the audible alarm is repeated after a specific time frame. The ring back delais user selectable in the Configuration mode. The “Relay” column shows whether each alarm is priority enough 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.
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.
WRONG POWER – Activates when the unit senses that input line voltage is above 150 VAC for a 115 V unit or below 160 VAC for a 230 V unit. There is a jumper located on the main control board that will indicate whether the unit is wired for 115V or 230V operation.
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 thefollowing 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.

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.

Sensor Errors

In addition to any alarms, the control will take the following action if it detects any of the unit’s sensors as being in error

to timed staging
Condenser probe failure| Alarm only, no change in compressor control
Ambient probe failure| Alarm only, no change in compressor control
Sample probe failure| Alarm only, no change in compressor control
Line/boost voltage sensing| Unit will operate normally, with boost voltage circuit Off

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.

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 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.
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

See the table below for representative readings:

Maintenance intervals

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.
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!
he 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 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.
2. 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
3. Use the UP and DOWN keys to change to OFF, then press ENTER. Upon restart, this configuration will automatically revert to the ON setting
4. Empty the freezer of contents and transfer them to another freezer. Leave the inner doors open.
5. 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.
6. Allow frost to melt and loosen. The loose frost can be removed carefully to move the decrease the process time.
7. Once the freezer is free of frost, use a mild non-chloride cleaning agent, rinsing with water.
8. Close doors and restore power.
9. Depending upon your temperature set point, storage temperature should be fully restored in 8 to12 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 must 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.

Options

Sample probe
There is access to a probe port at the rear of the freezer. It is uncovered when the access plate, held in place with 6 Phillips head screws, is removed.

Chart recorder

The 7-day chart recorder is added at the factory. See manufacturer’s owner’s manual.

Chart recorder fuse
The chart recorder fuse, 0.5 Amps, is located below the chart recorder power connection.
