Operation check, fault diagnosis, and testing of ships with pulse generator
Inspections using a pulse generator are used to simulate signal input for marine remote control systems and other systems,
and to check the operation of engines, motors, propellers, and other equipment.
Since operation checks and troubleshooting can be easily performed, it is effective for periodic maintenance and diagnosis of abnormalities.
Overview
Pseudo-signals from the pulse generator are input to remote control systems, engines, motors, etc., to check operation.
Data can be collected with various sensors and measuring instruments for speed, temperature, current, voltage, resistance, torque, etc.

What this case can do
Pulse Generator
Checking engines and motors
Using a pulse generator, dummy signals are input to the remote control.
Reproduce the position of the operation lever and throttle, and check if the engine, motor, control unit, etc. respond properly.
Check the operation of screws, etc.
Checks whether the throttle opening and propeller pitch of a marine engine are accurately reflected by giving pulse signals.
No need to start the engine. Check forward/reverse rotation of the screw using the A/B phase signal of the pulse generator as a dummy signal.
Abnormality Diagnosis and Troubleshooting
When a remote control system malfunction occurs, pseudo-signals are input to identify at which stage the error occurs.
Analysis of communication breakdown, signal delay, and malfunction factors.
Endurance test/stress test
Repeated pulse input is performed to test reliability and durability in long-term use.
Varying specific frequencies to check for abnormal operation and effects of aging.
Measuring instruments and signal converters
- Analog output selectable from 0-10V, 0-5V, ±10V, ±5V, 4-20mA (optional, specified when ordering).
Output update is as fast as 0.1 ms (speedometer). Full scale value can also be set.
- Alarm (warning) signal can be output when the specified rotation speed is exceeded. (Option)
- CAN output of measurement data. (Option)
- Customization, to combine multiple speed, position, angle, temperature, current, voltage, resistance, torque, etc. into one unit.
Power supply, connectors, wiring, etc. can be combined for ease of use.
