‣ If the system is in fault mode (Solid RED LED) Pressing the ON button will turn the system off.
9.1 125 VRTT Operation and safety features
Safety Features
‣ If the thruster is operated constantly in one direction for more than 3 minutes, the system will enter fault
mode. When in fault mode, the control panel LED will turn RED.
‣ If the system is receiving a PORT/STBD signal when turning the system on, the system will enter fault mode.
When in fault mode, the control panel LED will turn RED. This prevents the thruster from unintentionally
activating during start-up due to a wiring fault, or a second joystick accidentally being operated.
‣ If PORT and STBD signals are received simultaneously then the system will stop thrusting.
‣ The system will automatically power down after 1 minutes of inactivity for VRTT thrusters.
‣ When changing thrust instantly from PORT to STBD / vice-versa there will be a short delay to allow the
propeller to come to rest before acceleration in the opposite direction.
‣ The thruster motor is fitted with a thermal switch to prevent thruster activation if the motor overheats. If the
motor temperature is too high the system will stop operating and the panel LED will FLASH RED. Once the
motor returns to a safe temperature the LED will turn GREEN and thruster operation can recommence.
‣ The system will detect if the battery voltage is low and indicate this by turning the control panel LED AMBER.
The is for indication only and will not affect thruster performance.
‣ If the thruster hits a hard object while deploying, the circuit breaker on the ICU will blow and system will be
powered down. When the breaker is reset, and the system powers up, the VRTT will automatically retract
back to the home position.
‣ If the VRTT doesn’t reach its limit switch within 15s, depoloyment will stop, and red fault light will come on.
