Maintenance

After installation, maintenance must be performed according to the present manual. This processes have been established according to Spanish State Air Security Agency (AESA): Section 16 of RD 1036/2017 and Appendix H

To facilitate this work we are going to explain the procedures and methods that you will have to follow. We will divide the maintenance of the TS150 in two parts:

Preventive Maitenance

Preventive maintenance is required to ensure the optimal working state for the platform.

Before starting the operation you must be sure that you have at your disposal all the tools needed:

  • 2.5mm Hex wrench
  • 2mm hex wrench
  • 5.5mm open end wrench

Pre-flight Checking

  • Check all accessible screws are properlly tighten.
  • Power line is connected properly through the MIL-DTL-26482 connector (Figure: Tether Connector and Figure: Power Line Connector) .

  • Payload is configured, ready to operate and fixed correctly.
  • Check the LEDs.
  • Air filters are clean.

Two air filters must be checked. You can open the case pulling on one of its corners.

Take out the filter and clean them or replace them

  • Check the aircraft structure.

    • Fuselage without damage or fissures.
    • Arm connectors properly tightened and its security screws also.
    • Propellers screws properly tightened.
    • Landing gear without fissures.
  • Check that the power line GC Station - Tether have not fissures or damage.

  • Check the contact pins in the arms connection to ensure that they are clear. They should be able to establish easy contact. Open male banana connectors to get propper conection using a small tool if neccessary.

Optimal male banana contacts

Post-flight

  • Tight propeller screws and check they are not damaged.

  • Check the aircraft structure.

    • Fuselage without blows and fissures.
    • Motors fixed properly.
    • Nuts of the three arms are tightened rightly.
    • Landing gear without fissures.
  • Payload is fixed correctly.

  • Check that the power line GC Station - Tether have not fissures or folds while it rolls.

  • Tether cleaning before storage.

  • Open the drain situated on the bottom of the Ground Control Station, only in case of rain.

Warning

TS150 can’t operate while it is raining. If you are operating and it starts to rain, you have to finish your operation immediately, keep the Tether in its Ground Control Station and open the drain. TS150 is classified as IP53 device and this means it can be operated safely in light rain condition. As light rain criterion, the reference is considered to be the AEMET* description for lluvia débil. It is defined as a maximum rain of 2 [mm/h] (2 millimeters per hour) equivalent to 0,0787 [in/h].

Cleaning the system

  • All cleaning actions must be done with all system powered off.
  • After each flight use compressed air and/or a dry cloth to clean the complete system of dust and dirt.
  • If the system has contact with salty/marine ambient, do a special cleaning after each use.
    • Use a damp cloth with fresh water to remove the salt on the equipment. Never leave the equipment drying whith salty water on it.
    • Dissamble the arms from the multicopter and use fresh water to remove the salt from the motors. Let them dry, and check the contacts are not corroded. If corrosion exists, it is not safe to fly.
    • After cleaning with fresh water, be sure to let the equipment dry. You can use compressed air and/or a dry cloth.
  • Store it dry, never with humidity, in a cool and dry place away from direct sunlight.

Periodical events

Tether arms change

Every 1000 flight hours or damage. You must follow this steps and you will need a new arm (Figure: New Arm)

TS150 - Maintenance Manual

New Arm

  1. Get a new one. Write to sales@embention.com asking for NMTE009 Arm.

  2. Unscrew the set screws and the nut.

    TS150 - Maintenance Manual

    Step 1

  3. Disengage the arm by pulling it straight and parallel to its longitudinal axis. Be carefull not to damage or deform bullet connectors.

  4. Insert the new one. Be careful with the notch showed in Figure: Face 1 and Figure: Face: 2. Insert the arm by pushing it straight and parallel to its longitudinal axis. Be carefull not to damage or deform bullet connectors.

    Step 3

Overhaul

Every 5000 flight hours an special inspection is necessary

Check list:

  • Fully inspect all hardware components.
  • On the multicopter itself, you want to make sure there is no damage to gimbal, rotors, propellers, or other key components.
  • Check the contact pins in the arms connection to ensure that they are clear. They should be able to establish easy contact and should not be bent.
  • Check the upper and lower plates of the center frame for cracks and damage. If wear exists, it is not safe to fly.
  • Check the arms knobs for wear. If the frame arm is loose after the knob is locked it is not safe to fly.
  • Turn on the aircraft and listen for any abnormal noise or vibration from the cooling fans located on the bottom cover of the aircraft.
  • Check the motor base for cracks and damage. If wear exists, it is not safe to fly.
  • Check the connection between the motor base and the arm tube.
  • Check the propellers. If there is any bending, breakage or cracks on a propeller, do not use it.
  • Checking the landing gear for cracks and damage. If wear exists, it is not safe to fly.
  • Check the motors for deformities and the motor spins freely and looks fine.
  • Remove the propellers and start the motors. Carefully examine the edge of the motor rotor and confirm that the shaft is perfectly centered on the motor. Check for any abnormal or excessive vibration. If excessive vibration is detected , it is not safe to fly.
  • Remove the propellers and start the motors. Listen carefully for any abnormal noise, which may indicate that the bearings have worn out and the motors need to be replaced.
  • Check all accessible screws are properlly tighten.
  • Payload is configured, ready to operate and fixed correctly.
  • Check all the three LEDs.
  • Air filters are clean.

Despite of positive result of this inspection, continuing the operation will be under customer responsability. After this inspection an overhaul is recomended at Embention facilities.

Corrective Maitenance

This procedures must be performed when some system or part of the aircraft has suffered damages.

Warning

TS150 is a complex unmanned aerial system, for this reason we recommend to the user to perform only simple repairs. To solve other problems, get in touch with Embention.

If one of the propellers is broken, you must follow this steps and you will need:

Conditions Of Storage

Store the product in a cool, dry place away from direct sunlight to ensure that the built-in LiPo battery does NOT overheat. Recommended storage temperature: between 22° and 28°C (71° and 82° F) for storage periods of more than three months. Never store in environments outside the temperature range of -20° to 45° C (-4° to 113° F).

This equipment has lipo batteries integrated on the system.

DO NOT store the battery for an extended period after fully charging it. This can damage the battery. If the multicopter will NOT be used for 10 days or more, you should store it charging the batteries in storage mode (3.7V to 3.8V per cell). Refer to your battery charger manual to do this.

Battery life may be reduced if not used for a long time.

Fully charge and discharge the battery at least once every 3 months to maintain battery health. Refer to your battery charger manual to do this.
