Connection for Temperature A probe. Connection for Temperature B probe. Connection for incoming power. Connection for RS-485 communications interface. Redundant Connection for RS-485 communications interface. Manual Fill button used to override the TEC 3000 software and manually fill the freezer. These connections monitor the alarms for High Temp A, Low Level, Low Battery, and LN2 Supply. They can be wired to any alarm system that uses Normally Open (NO) contacts. These connections monitor ALL alarms. They can be wired to any alarm system that uses Normally Open (NO) or Normally Closed (NC) contacts. Connection for the main wiring harness. All of the connections for the solenoid valves, lid switch, bypass sensor, etc. are located here. Connection for level sensing system. Level sensing is achieved via differential pressure sensor, located inside the TEC 3000. The tube from the level sensing line on the freezer connects here. The connection is a 1/8” (3.2mm) OD hose barb.

Dewar 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 filling 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 apply 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.

Calibration of Temperature Probes Each of the temperature sensor probes (A and B) used with the TEC 3000 have been calibrated at the factory using the “Low Temperature Range” method. This calibration method provides a level of accurancy of +/-1.8°F (+/-1°C) when operated in the altitude range of 1000ft. to 1500ft. (305m to 457m). Further calibration should not be required unless desired by the end user. Refer to the TEC 3000 Technical Manual for information on calibration methods and procedures.

TEC 3000 Quick Reference Guide Password and Security Setup The TEC 3000 can store up to 10 different passwords. Each password can be assigned its own security level ranging from Level 1 to Level 4. Table 3 below shows which settings can be changed with each security level. A security level of 4 is required to adjust any password. The default (or “Global”) password for the TEC 3000 is “3456”. All parameters may be adjusted by using this password. Record all passwords and security settings and store in a safe place. NOTE: MVE recommends changing the global password, as it is common to all units. If the global password has been forgotten, contact MVE Customer Service for details on how to reset passwords.
