Page 4: Safety Notes
Jets-Munt Representatives: Check the current dealer list on our web page, www.jets-munt.com Safety Notes Please remember the engine is not a toy and has the potential to cause bodily harm to you and others if misused. The MERLIN engine is a sophisticated piece of machinery and should be treated with a high level of safety when it is in operation. -
Page 5: Engine Description
forward and allow the fuel to exit through the fod screen and mop up with a rag. It is no use tipping the engine with Merlin Instruction manual V1.4 Pag: 5 the exhaust downwards as excess fuel will not be released due to the ngv being mounted forward of the engine rear. - Page 6 fuel should contain a small percentage of oil and uses part of this fuel to lubricate its two ceramic high speed bearings. The fuel for the engine is provided from an external fuel tank through a small electrical pump that uses a three phase brushless motor. The engine speed between idle and maximum is controlled by varying the speed of the fuel pump through an electronic controller called an ECU (electronic control unit), that is connected to the engine trough a 3 wire digital data bus.
- Page 7 ECU Data Terminal The data terminal plugs into the ECU via the lead supplied. The display can be used for starting and test running. This socket also doubles as digital connection to a computer. The display can be installed permanently on board. This Smart Data terminal includes dedicated screens for radio checking, last shutdown cause and other special turbine operations.

Page 8: Engine Installation
Connect the 3 wire powerbus to the engine and to the ecu. This lead can be extended. Although Data signal can be used with lead lengths up to 10 meters, the power looses on power wires (red and black) will increase with length, so thicker cooper section must be used on long lengths. -
Page 9: Aligning Transmitter With Ecu
Confirm you have connected the ECU input to the throttle channel of your receiver, DISCONNECT the ecu battery, and connect the Data Terminal into the ECU. Remove all rates, mixes and throttle travel settings in the transmitter. Before doing any adjustment on the ecu, check that your transmitter is sending the correct signal by checking the reading of “Pulse”... - Page 10 The screen will now change to: Move the trim to low (or switch the “engine cut” switch to On) and throttle stick back to zero and again press the right hand button (+). The display will now change to: Leaving the throttle stick in the minimum position, raise the throttle trim to the full up position or switch “Engine Cut”...
- Page 11 There are many more parameters that can be modified in the ECU, but we have specifically programmed your ecu with the optimum settings, further adjustment should not be required and can only be carried out by Jets Munt SL or your authorized dealer. Preparing the engine for running A suitable platform/table/workbench is now required to clamp the test stand onto.
- Page 12 The kerostart system used on this engine is a reliable and well tested system that produces very smooth and trouble free starts. However, extra care and attention must be paid when starting a kerostart engine. The main difference between gas and kerosene is that in the case of a failed ignition, the gas dissipates quickly on the air and don't keep inside the engine.
- Page 13 First engine runs · Confirm your test stand is securely fixed to a bench or heavy table. Keep your ear defenders within easy reach and a CO2 fire extinguisher handy. VERY IMPORTANT ON KEROSTART ENGINES. Do not use a powder extinguisher, it will damage the engine.
- Page 14 First the internal glow plug will be energized. After 3 seconds, the starter will be powered up to have the rotor turning at slow speed (3000- 5000 RPM). Once the rotor is at correct speed, the pump and solenoid valves will be energized. Few seconds later the kerosene will ignite and the exhaust temperature will begin to increase.

Page 15: Auto Restart Function
Move the trim to the low position to abort the sequence. If there is a fire in the engine and the problem is because the starter has failed or the engine is seized (not turning), IMMEDIATELY APPLY THE FIRE EXTINGUISHER through the intake side of the engine, never trough the exhaust. - Page 16 ·Autorestart: In particular case of a fuel bubble that momentarily stops the combustion, the ecu will detect this condition by monitoring the rpm, temperature and pump power, and then the ecu triggers the auto restart sequence. This sequence is done with the engine hot, so the power is restored quickly.
- Page 17 Disclaimer: There are no circumstances Jets Munt P/L or any of its Service Agents and employees will accept or be held responsible for any losses or damages the Auto Restart feature causes should the owner operator choose to enable this function.
- Page 18 thrust, with the low half stick travel being not used. Although that with current digital TX the pilot can modify the throttle curve to suit his needs, three throttle curves have been added to simplify the setup for most of the installations. These curves are selected under the RADIO menus: FULL EXPO: Mean linear RPM, it is the default setting and the mode used for all previous software versions.
- Page 19 As a general guideline, use an exhaust tube of a diameter equal or larger than the specified in page 5, with a gap between the engine exhaust and beginning of exhaust tube (excluding the bell mouth) of 25mm. later you can experiment moving the engine 5mm forward or aft to see if performance is better.

Stop: Engine off. Cooling: Starter is operating to cool the engine. GlowBad: Defective or disconnected glow plug. StartBad: Defective starter, insufficient RPM reached during start, RPM sensor damaged, too thick oil used on previous run, no cooling sequence done in previous run. Low RPM: Engine had been shutdown because the speed has fallen below the minimum. -
Page 21: Fuel And Oil
A XM Aviation UAT is a best method of reducing the possibility of air bubbles in the engine fuel line. This is a very important aspect of the operation of any turbine engine. Use a appropriate adapter for the 6mm tube output of the UAT to the 4mm in the inlet side of the fuel pump, direction of fuel flow is clearly shown at the top of the pump. -
Page 22: Feed Pipes
Feed Pipes All the pipes must be Polyurethane or nylon as provided by Jets Munt or Tygon (like the ones used by gasoline engines). Do not use Tygon on the pressure side of the fuel pump. Silicone tubing must not be used anywhere in the installation as it is dissolved by fuel and oil. -
Page 23: Extra Ecu Functions
Do not change the voltage, please contact to Jets Munt first -Adjust the pump power at startup. The fuel flow during ignition phase must be finely tuned for each engine/pump combination, and this is done at factory during test. -
