2.0 MVE Variō Plumbing Connections Connect a transfer line (included with freezer) from an LN2 supply tank to the fill connection at the rear of the freezer. Optimum supply tank pressure is 22 to 35 psi (1.5 to 2.4 bar). Although the plumbing assembly has a 50 psi (3.45 bar) pressure relief device, it is recommended that the supply tank be pressurized below 35 psi (2.4 bar) to reduce the LN2 “flash-off” rate during cooling cycles and to maximize the cryogenic valve life. The supply line can be insulated to minimize LN2 transfer losses. After the transfer hose is securely coupled to the freezer and supply tank, ensure all connections are leak free by opening the valve of the LN2 supply tank and applying a soap and water solution to each field joint. You should not see bubbles forming at any joint. Wipe away excess soap and water when finished. Before removing the transfer hose, ensure the LN2 supply tank valve is closed. Slowly and carefully loosen the transfer hose connection to vent any remaining pressure in the line before disconnecting the hose.

5.0 Calibration of Temperature Probes Each of the temperature sensor probes used with the Variō Pro have been calibrated at the factory using the Low Temperature Range method. This calibration method provides a level of accuracy of +/-1.8°F or +/-1°C when operated at an altitude range of 1000ft – 1500ft (305m - 457m). Further calibration should not be required unless desired by the user. Refer to the Variō Pro Technical Manual (PN 14930250) for information on calibration methods and procedures.

ALARM Cooling Sensor Fail Started at: 01/01/2011 12:00 PM

The Variō Pro has lost communication with the cooling sensor. The sensor has either been disconnected from the controller or has been damaged.

ALARM Supply Time X min Started at: 01/01/2011 12:00 PM

The Supply Time alarm is triggered when the temperature of the incoming nitrogen fails to reach the Inlet Temp Setpoint within the time specified by the Supply Alarm Delay. Once activated, the Variō Pro will terminate the Hot Gas Bypass cycle and begin supplying the freezer with N2.

ALARM Valve Stuck Open Started at: 01/01/2011 12:00 PM

The Valve Stuck Open alarm is triggered when the Cooling Cycle has terminated and the Inlet Temp Sensor fails to warm above the Inlet Temp Setpoint within the time specified by the Stuck Open Delay time setting.

ALARM Valve Stuck Closed Started at: 01/01/2011 12:00 PM

The Valve Stuck Closed alarm is triggered when the Variō Pro has begun feeding N2 to the freezer, and the Inlet Temp Sensor fails to cool to the Inlet Temp Setpoint in the time specified by the Stuck Closed Delay time setting. Note that although this alarm is similar to the Supply Time Alarm, it will remain active regardless of the ENABLED/DISABLED status of the Inlet Temp Sensor.

Alarm Display

Description

ALARM Lid Open X min Started at: 01/01/2011 12:00 PM

This alarm is triggered when the Lid Switch Installed setting is set to YES and the freezer lid remains open for the duration of the time specified by the Lid Open Alarm Delay. Note that by default, the Lid Switch Installed setting is set to NO.

ALARM Cooling Time X min Started at: 01/01/2011 12:00 PM

The Cooling Time Alarm is triggered when the Variō Pro has initiated a Cooling Cycle and the Chamber Temp fails to reach the minimum chamber temp setpoint in the amount of time specified by the Cooling Time Alarm Delay.

ALARM Power Failure Started at: 01/01/2011 12:00 PM

The Power Failure Alarm is triggered when the Variō Pro is equipped with battery backup and has been running on battery power for 30 minutes. With typical use, a battery backup equipped Variō Pro will retain functionality for 48 hours after the loss of its primary power source.

ALARM Low Battery Started at: 01/01/2011 12:00 PM

The Low Battery Alarm is triggered when the voltage of the battery backup powering the Variō Pro drops below 21VDC.

Communications Loss Unit 1 Started/Ended at: 01/1/11 12:00

The Communications Loss screen is displayed in the event that the Display Screen has been disconnected from the Variō Pro control board. This screen does not necessarily indicate a loss of system functionality, but it does impair the user’s ability to monitor the system status.
