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 roof 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.

Configuration & Maintenance The HEX is composed of the key components as the following : Chassis , Heat Exchange Core , Controller and Fan Tray . The user can slide out the fan tray easily for replacement of the controller and fans . Item Q'ty Description 1 1 Chassis assy 2 1 Controller assy 3 1 Internal fan tray 4 1 External fan tray Page 5 Part no. : Delta model no. : HEX050QA 1-5. Thermal path and Airflow baffle With the forced convection using the axial fan , the warm air generated by the equipment will be blowing into internal return opening and pass though the HEX core, then flow out from internal supply opening , the air supply 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 from external air inlet side and bring the heat of the HEX core out from the external air exhaust side . The thermal exchange path is shown in the figure below. Page 6 Part no. : Delta model no. : HEX050QA 2. Electrical specification 2-1. Indicator & Connector (HEX panel side) Connector " -48V VDC " Connector "COMM" Alarm logic depends (Pin1 to Pin2 ----- MAX. 75VDC ,50mA) Fan and NTC normal Pin1 and Pin2 dry contact output open Fan failed Pin1 and Pin2 dry contact output close NTC failed Pin1 and Pin2 dry contact output close NTC FAILED The NTC failed alarm will be active when NTC resistor work in abnormal range such as 1.NTC cable does not connect to control board 2.NTC damage (short or open) Fan will run at high speed when NTC failed alarm is active. Switch "TEST" When pressing the "TEST/CLEAN" button, both outer fans and inner fans will run from low speed to high speed for test. 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 red. It can be turned off by press the "TEST/CLEAN" button again.
