1 Product Overview
1.1 Safety instructions
TM120B is used for marine propulsion systems and is powered by a battery, thus it is
inherently dangerous to some extent. Before using it, please carefully read the safety and
warning instructions in this manual. Failure to follow these instructions may result in personal
injury or machine damage.
1.1.1 Safety features
The following are the common safety features of TM120B.
Safety features Description
Overcurrent protection
When the current is too high, TM120B will stop running to
protect the motor.
Overtemperature
protection
When the temperature is too high, TM120B will automatically
reduce power to protect the motor.
Locked-rotor protection
If the propeller is entangled by debris, TM120B will stop
running to prevent damage.
Overvoltage protection
When the battery voltage is too high, TM120B will be
prohibited from starting.
Undervoltage protection
When the battery voltage is too low, the underwater unit will
be prohibited from starting.
8
1.1.2 Precautions
Battery
The rated voltage of TM120B is 24V and 12V respectively, and the max. current supported is
36A and 40A. If you are not using Parsun's standard battery, please select a battery according
to the following parameters.
When TM120B voltage is 24V, choose a battery with a voltage of 17-32V and a continuous
discharge current above 50A.
When TM120B voltage is 12V, choose a battery with a voltage of 10-18V and a continuous
discharge current above 50A.
If the voltage used is beyond the scope, TM120B may give out an alarm and produce fault and
irreparable damages.
Positioning accuracy
The precision of position holding may be affected by the following factors:
In the areas with shelters, such as valleys and bridges, or due to weather influence or if
satellite is just above TM120B, TM120B’s GPS signal may be instable.
Proximity to high-voltage lines, radar, or metal objects may cause magnetic interference.
Too high wind speed or too large or complex water current.
Low battery power, which results in reduced thrust.
Safety Precautions
Before use, ensure you are familiar with the basic operations, such as starting/stopping,
steering, retracting, and deploying.
Before use, please check the battery level.
Before use, ensure that the base screws are securely fastened.
When operating TM120B, do not apply excessive force to the foot pedal.
Do not use the automatic control function in areas with heavy boat traffic, narrow
waterways, poor visibility, or extreme sea conditions.
When folding or unfolding TM120B, do not place your fingers on moving parts.
After driving, disconnect TM120B from the battery.
After operation, stow the TM120B on the deck.
When connecting the battery, make sure the polarity is correct and the connection is
secure.
9
Keep the battery terminals clean and free of conductive materials.
After use in saltwater, clean the TM120B’s surface with fresh water.
Before installing or removing the propeller, ensure the TM120B has been powered off.

2 Installation
2.1 Install the unit
Step 1: Take off the right and left coverplates (A) on both sides through the mounting holes on
the base and six mounting holes (B) will appear; after the unit is retracted, the four mounting
holes (C) at the middle of base will be seen; TM120B can be retracted and deployed by
referring to Chapter 3.1“Machine Retraction and Deploying”.
Step 2: Place TM120B on the ship's deck, align the shaft as close as possible to the ship's keel
(A). For installation, it is recommended to use 6 screws; otherwise, use at least 4.
During installation, leave a gap of at least 40 mm between the shaft and the upper edge of the
ship’s gunwale or front segment of extension bracket.
(Deck mounting mode)

C
17
If TM120B can't be mounted on the deck, mount it outboard by fixing an extension board on
the boat deck before fixing TM120B onto the extension board.
Note: Ensure that the extension board has enough strength to prevent crack of extension board
and falling of machine into water.
(Outboard mounting mode)
18
A
2.2 Install the propeller
Insert pin (B) onto the motor shaft, then align the slot (A) of the propeller with the pin and
install it onto the motor shaft. Install the propeller (C), washer (D), locknut (E), anode (F), and
screw (G) in sequence.
Note: Ensure the correct installation sequence and fasten the propellers, to prevent running
faults of machine or personal injury.
2.3 Install the pedals (optional) and heading sensor (optional)
On the foot pedal there are three holes (A), which can be used to secure the machine to the
deck of the boat. Fix it onto the deck to prevent the foot pedal from moving.
The heading sensor should be installed horizontally, with the arrow pointing forward and
aligned parallel to the keel (B) of the boat; it is recommended to install it close to the keel.
The heading sensor should be installed as far away from unit as possible, at least 0.9m (1 foot),
to avoid magnetic field interference.
The heading sensor should be installed as far away from the power cable and other electronic
equipment, to avoid magnetic field interference on the working effects of heading sensor.

3.4 Anti-tangling of spring wire
When spring wire is tangled for over 1 circle under non-manual mode, it will trigger anti-
tangling and the motor will be powered off temporarily, the ship controller will rotate
automatically to untangle, and then return to the angle that triggers anti-tangling; then, the
motor will be powered on automatically.
When the spring wire is winded for over 1 circle under manual mode, it will trigger limit
protection and the motor can't rotate anymore.
Ensure that the spring wire is not tangled when the unit is powered on, so that anti-
tangling protection can become effective normally.

4.6 Bow/heading hold
TM120B will plot an invisible route in the direction indicated by the heading. During this
period, the boat will automatically follow the route, and the speed can be adjusted using the
control knob. Under bow/heading hold mode, the steering direction can be changed through
the remote control, the boat will replan its route along with the adjusted direction, and sail
along with the new route.
This function will stop after triggering other modes.
