Description 1-1. General description : The Heat Exchanger (HEX) is designed for direct air to air heat exchange to remove the heat from the cabinet . It is easy to be installed in the cabinet with the nuts. (Recommended on the door of the cabinet) The internal and the external air circulation loops of the HEX are separated to prevent the introduction of dust, humidity and dirt. The fan on the external air loop conforms to IP55 protection rating. 1-2.

Thermal path and Airflow baffle With the forced convection using the axial fan , the warm air generated by the equipment will be blowing into the upper inlet and pass though the HEX core, the temperature will be lower on the other side of the core. The air return of the cold air will be used to cool down the system ; While on the opposite side , cooler air from the out environment will be drawn into the lower inlet and bring the heat of the HEX core out from the upper outlet . The thermal exchange path is shown in the figure below. Page 6 Part no. : Delta model no. : HEX050PA 2. Electrical specification 2-1.

( 75VDC )50mA Page 7 Part no. : Delta model no. : HEX050PA Switch "TEST" When pressing the "TEST/CLEAN" button, both outer fans and inner fans will run from low speed to high speed for testing purpose . The testing process is around 2 minutes, and the LED of INNER FAN and OUTER FAN will be blinking in GREEN color. When the fan failed, the LED will be blinking in RED . and it can be turned off by pressing the "TEST/CLEAN" button again . LED of "INNER FAN & OUTER FAN" (GREEN) : Fan normal (RED) : Fan failed (Blinking GREEN) :Fan is normal during test (Blinking RED) : Fan failed during test LED of "STATUS" (GREEN) : NTC normal at Standalone mode (RED) : NTC open or short at Standalone mode NTC position : J6 for choosing Inner sensor (on control panel) or External sensor (COMM port Pin7 & Pin8 ) Page 8 Part no. : Delta model no. : HEX050PA 2-2.
