  • Page 10: Additional Safety Precautions And Notices

    MT180 ADDITIONAL SAFETY PRECAUTIONS AND NOTICES High Pressure: The refrigerant is stored under high pressure and in a liquid state. If the valve is opened or the container punctured, and the refrigerant is sprayed to natural air, there is a high potential for injury to R134a exposed skin and eyes.

  • Page 11: Disclaimer

    DISCLAIMER Warning: All warning and safety precautions mentioned here are for the protection and safety of the operator. Should they be ignored or not followed correctly, no liability is accepted. Pre-requisites The following prerequisites identify both the hardware and software skills required by the operator. Operator Skills The operator must have a working knowledge of electronic control systems, the use of touch screen activated units and experience on cooling requirements for various cargoes.

  • Page 12: Operator Introduction

    Start-Stop Button The Start-Stop button is located on the access panel built into the side of the MT180 and sits alongside a USB port. A single press of the button will start the unit, the startup process taking approximately 1 minute.

  • Page 13: Hmi Control Panel

    HMI CONTROL PANEL Caution: The Unit’s software and configuration should only be accessed and altered by certified Operators. Altering settings may result in the unit not functioning as required, which may result in damage to the unit and or the loss of product.
  • Page 14 MT180 HMI CONTROL PANEL Item NAME Description Primary Mode This mode runs all fans at maximum speed, all the time. It is only to be used for trouble-shooting purposes as it provides maximum cooling capacity, even when the set point has been reached. Using this mode during day-to-day operation will result in poor fuel economy, and poor temperature regulation.
  • Page 15 HMI CONTROL PANEL Item NAME Description This indicator is driven by the actual change in the regulating temperature (RAT). It is independent of the unit mode. ↓ When is displayed the RAT is decreasing. → Temperature When is displayed the RAT is remaining constant within a dead- Trend Indication band equal to the hysteresis.

  • Page 16: Startup And Shut Down Procedures Pre-Trip Inspection

    MT180 HMI CONTROL PANEL Item NAME Description It should be further noted that takes precedence over the Secondary Mode Set-Point (10). It is possible to have a 0°C Set-Point (10), and a cont set-point of 0°C. In this case the DAT will regulate at 0°C, and the RAT will simply go down to the lowest temperature the box insulation and ambient conditions will allow.
  • Page 17 HMI CONTROL PANEL Item NAME Description ALARM Jump directly to the Alarms screen. Pressing the power button will switch the entire system off, both the Engine and HMI. To only switch the engine-off use the Stop/Start button mounted below the HMI. MODE T2 + T3 Jumps to the page (12)

    MT180 STARTUP AND SHUT DOWN PROCEDURES Pre-Trip Inspection The following Pre-Trip Inspection should be completed before starting the unit and loading the trailer. While the Pre-Trip Inspection is not a substitute for regularly scheduled maintenance inspections, it is an important part of the preventive maintenance program designed to head-off operating problems and breakdowns before they happen.

  • Page 19: Loading Procedure

    Caution: DO NOT block the evaporator inlet or outlet. Caution: DO NOT block the evaporator inlet or outlet. 4. The cargo must be pre-cooled before loading. MT180 transport refrigeration units are designed to maintain loads at the temperature at which they were loaded.

  • Page 20: Startup Procedure

    MT180 STARTUP PROCEDURE The unit uses a single button for multiple purposes, so multiple presses will invoke contradictory actions. Please ensure to PRESS and WAIT for a response from the until before pressing again. During the Start Up procedure and the Self- Test Procedure an hourglass is displayed.

  • Page 21: Changing The Set-Point And Modes

    CHANGING THE SET-POINT AND MODES Changing the Set-Point To change the Set-Point, do the following: Press the (T1) button once. Check that the Set-Point is flashing. 2. Change the Set-Point up or down using the (T3) or (T2) buttons. Confirm the Set-Point change by pressing (T1) again.

  • Page 22: Shutdown Procedure

    MT180 SHUTDOWN PROCEDURE There are two options: Suspend cooling (Includes a time delay of 30 minutes until HMI and Control auto shut down). If the unit is fitted with an optional door sensor the delay time is extended to 90 minutes.

  • Page 23: Complete Unit Shutdown - Using The Start/Stop Button

    SHUTDOWN PROCEDURE Complete Unit Shutdown – Using the Start/stop button To shut down the unit, do the following: Hold the Start/Stop button down for 5 seconds. 2. The engine will switch off. 3. After the Start/Stop button is released and the engine has come to a complete stop, the HMI will switch off after 3 seconds.

  • Page 24: Modes Of Operation

    MT180 MODES OF OPERATION The primary modes dictate maximum engine speed, the condensing temperature and temperature control accuracy. Auto mode is always recommended as it provides the best performance, fuel economy and temperature regulation accuracy. The secondary modes can either be used individually, or all at the same time, or none of them, with any of the primary modes.

  • Page 25: Mode Options

    MODE OPTIONS Once you have entered the Mode menu, the mode options labels will be suspended on the screen above the T buttons. Button Label Long Name Description Manages the engine speed, condenser fan speed and AUTO Automatic evaporator fan speed automatically. This is the recommended Primary mode.

  • Page 26: Automatic Mode

    MT180 MODE OPTIONS Automatic Mode In Automatic Mode, the condenser and radiator fans do not run at full speed continuously unlike in Maximum mode. During the initial pull-down or cooling phase to reach the setpoint temperature, the fans run at full speed as this produces maximum cooling regardless of ambient conditions. Once the setpoint has been reached, the condenser fans will slow down along with the engine speed.

  • Page 27: Priming Mode

    MODE OPTIONS Priming Mode Priming Mode is part of the startup procedure that comes into effect when there is a failed attempt to start the unit, or the engine stops unexpectedly in the first 2 minutes after start-up. The failed start is owing to lack of fuel, air in the fuel line, a blocked fuel filter, a blown fuse or any relevant condition preventing a successful start.

  • Page 28: Post Trip Inspection

    MT180 POST TRIP INSPECTION The following post-trip inspection should be completed by an experienced technical resource. Cleaning the unit a. Clean the exterior of the unit b. Visually inspect for any debris i.e., packaging, plant material or other items that may have been left behind 2.
