Page 9: General Description
8 of 116 pages 5. General description units, models SCU-40 and SCI-40 are electric powered picture frames, cooling STAR COOL and heating units operating on refrigerant R134a or R513A. The unit is designed to maintain cargo temperatures in a range from -30°C (-22°F) to +30°C (+86°F). The unit is designed to operate in ambient temperatures from -30°C (-22°F) to +50°C (+122°F). -
Page 10: Function Description
9 of 116 pages racy is ±0.25°C (±0.45°F). The unit can operate the evaporator fans in low speed and high speed. From the controller display, Normal or Economy mode can be selected under the Operation menu. In Economy mode the fans always run on low speed. In Normal mode the fan speed can run in high or low speed depending on running conditions. -

Page 14: Dehumidification
13 of 116 pages 6.7 Dehumidification The dehumidification function dehumidifies air in the container by means of a heater. This function can only be activated if the temperature control function is active. Dehumidification is achieved by decreasing evaporator surface temperature. This is done through activation of the heater and letting the temperature control increase cooling capacity resulting in an evaporator temperature descending. -

Page 16: Alarm Action System
15 of 116 pages General information If the Tevap sensor is not OK, adaptive defrosting uses a reduced defrost interval compared to normal calculated defrost intervals. Setpoint alteration leads to a new calculated defrost interval, and defrost starts when the defrost criteria is reached. With manual defrost initiation the current defrost interval is set to default defrost interval. - Page 17 16 of 116 pages Event ID Param. 1 Param. 2 Param. 3 Param. 4 Param. 5 Tsup Supply air temperature [°C] Tret Return air temperature [°C] Tusda1 USDA 1 temperature [°C] Tusda2 USDA 2 temperature [°C] Tusda3 USDA 3 temperature [°C] Tcargo Cargo temperature [°C] Tset...

Page 19: Function Test
18 of 116 pages 7.1 Function test Function test is a unit component test (non-destructive). The test is based on a GO/NO GO proce- dure. All tests must be executed without failure one by one for the function test result to be PASS. The tests can also be performed individually. -
Page 20: Full Pti
19 of 116 pages NOTE: At ambient temperature above +40°C (+104°F) and below -20°C (-4°F), the unit has to be running in normal operating mode at setpoint of 0°C (32°F) for of 10 minutes with com- pressor running before executing a function test or PTI test. The reason for this is to en- sure correct function of unit during PTI test or function test. -
