13 MEGA-TEC Series Standard Components Dual Independent Compressor Circuits The MEGA-TEC unit contains two separate refrigerant circuits. Circuit 1 uses a 2 stage scroll compressor and electronic expansion valve along with high and low pressure transducers. Suction temperature is also measured to provide superheat of circuit 2. Circuit 2 uses a single stage compressor and electronic expansion valve along with high and low pressure transducers. Suction temperature is also measured to provide superheat of circuit 1. Using both circuit 1 and circuit 2, the MEGA-TEC unit can provide 35%, 0%, and 100% cooling capacity. Separate refrigeration circuits also allows for operation of the unit at partial capacity if service is required on one circuit. Outdoor Fan Assembly The EC outdoor industrial fan assembly maintains its high efficiency across a wide operating range. The result is a significant reduction in energy use when the motor is run at reduced speeds. Specifications Industrial grade fan assembly Soft start Reverse polarity and locked motor protection Painted black Aluminum blade sprayed with PP plastic Steel grill coated with black plastic Dirty Filter Switch All unit models utilize an adjustable dirty filter pressure switch to indicate when the filter needs to be changed. The dirty filter switch measures the pressure difference on both sides of the filter through tubing routed to the blower and vent areas of the unit. When pressure increases to a pre-set measurement in the switch, an alarm signal is sent to the unit programmable logic board, then to the LC controller. The controller energizes a set of normally open contacts. A LED light is also installed on the exterior cabinet surface to indicate a filter change is required. Page 13 of 31

14 MEGA-TEC Series Standard Components Filter Replacement Light A light is provided on the exterior of the unit that illuminates when the unit filter needs to be replaced. The light is located on the front right side of the cabinet. When the alarm signal for a dirty filter is reset through the LC controller, the light will no longer be illuminated. Indoor Blower Operation Pressure Switch All models will utilize an indoor blower operation switch to indicate when blower airflow is not adequate for unit operation due to a failed evaporator blower motor or other mechanical airflow issue. The switch measures the pressure difference on both sides of the blower partition through tubing routed to the blower inlet and outlet areas of the unit. When pressure decreases below a pre-set measurement in the switch, an alarm signal is sent to the unit programmable logic board, then to the LC controller. The controller energizes a set of normally open contacts. Compressor Control Module A low voltage monitoring device is used to monitor power and indicate a low incoming voltage situation caused by inadequate shore power or generator operation. The monitoring device protects the unit against compressor contactor chatter and reverse compressor rotation during these situations. Return Air Temperature Sensor All models have a return air temperature sensor installed for operation in orphan mode. The return air temperature sensor is also used for indoor temperature averaging with the use of the LC controller. The return air sensor is located in the upper part of the return opening in such a way that it is exposed to the entering airstream. Information is received by the unit logic control board using a 10K resistance signal. An alarm will be sent to the LC controller if the return air temperature sensor is disconnected. Supply Air Temperature Sensor All models use a supply air temperature sensor. By monitoring the air temperature leaving the supply opening, the unit logic control board is able to monitor the air entering the shelter. Information is received by the unit logic control board using a 10K resistance signal. An alarm will be sent to the LC controller if the supply air temperature sensor is disconnected. Mixed Air Temperature Sensor Economizer models use a mixed air sensor to monitor the vent air intake and return air intake mixture entering the evaporator coil. Information is received by the unit logic control board using a 10K resistance signal. An alarm will be sent to the LC controller if the mixed air temperature sensor is disconnected. Page 14 of 31

15 MEGA-TEC Series Standard Components Outdoor Air Temperature and Humidity Sensor All economizer models use a outdoor air temperature and humidity sensor. Using the sensor, the unit logic control board is able to monitor the outdoor air temperature, humidity and dew point. When conditions are acceptable for bringing in cooler outdoor air, the unit logic control board will allow economizer operation. The unit software can be set to operate economizer in Dry Bulb, Humidity %RH or dew point. An alarm will be sent to the LC controller if the supply air temperature sensor is disconnected. Compressor Crankcase Heater All economizer models have a crankcase heater installed as standard. The crankcase heater is a belly band style heater encircling the base section of the compressor housing. When the unit is not in operation, the crankcase heater is a precautionary measure to prevent compressor oil migration, deter oil and refrigeration from mixing and avoid refrigerant condensation. Care must be used when servicing the unit to avoid being burned by the belly band attached to the compressor base. Always disconnect power when servicing this area of the unit. Economizer Air Intake Quality Dust Sensor All models include a dust sensor to monitor the outdoor air quality entering the economizer damper area. When conditions are unacceptable due to particulates in the air including farm field debris, highway dust and dirt, or other particulates, the economizer is disabled. The sensor monitors dust density by using an optical system. The optical portion of the sensor uses a light-emitting diode and light detector. The sensor is shipped pre-set, but may be adjusted for less or more sensitivity. High Pressure Transducer All models have a high side pressure transducer. The transducer will be used for system monitoring of high side system pressures. This information will be used to indicate when outdoor coil cleaning is necessary based on outdoor conditions and system pressures. When high pressure increases beyond a pre-set measurement when compared to outdoor temperature stored in the unit programmable logic board, an alarm signal is sent from the unit programmable logic board to the LC controller. The controller energizes a set of normally open contacts to indicate abnormal high system pressure. The high pressure transducer also controls the outdoor condenser fan and motor to increase outdoor airflow during high outdoor ambient conditions. Page 15 of 31

16 MEGA-TEC Series Standard Components Low Pressure Transducer All models have a low side pressure transducer installed on the suction line between the evaporator coil and compressor. The transducer is used for system monitoring of low side system pressures. This information is used to indicate a loss of system refrigerant. When low pressure drops below a pre-set measurement stored in the unit programmable logic board, an alarm signal is sent from the unit programmable logic board to the LC controller. When a loss of charge is measured, the LC controller energizes a set of normally open contacts to indicate refrigerant loss and that the unit needs to be serviced. The low pressure transducer is also used for operation of the electronic expansion valve (EEV). Superheat is displayed at the unit using the TEC-EYE diagnostic tool. High Pressure Safety Switch All models have a high side pressure switch as a safety device. This device is connected to a safety rated set of contacts, and operates if high system pressures reach an unacceptable level. When activated, the unit will shut down compressor operation immediately. After a predetermined time, the unit will attempt to restart. If the switch is activated during the restart, compressor operation will lockout, and an alarm signal will be sent to the LC controller. This is a safety device that disables unit operation at a high refrigerant pressure. It is also used to protect unit components including the electronic expansion valve and compressor. Never disable the high pressure safety switch. Activation of the switch normally indicates the unit needs to be serviced. Page 16 of 31
