you have to follow the testing on-board procedure booklet (supplied by yard) and the maker's instruction books (mostly for adjustment & set points).
Briefly:
- some alarms and trips are tested by isolating the sensors and apply some increased / decreased signals (current, pressure, temperature, etc.). Sometimes you need some master gauges or current injectors in order to perform this action.
- you may alter the set points in the AMS (alarm monitoring system).
Be cautious:
1. when you have to run the engine in order to activate the trips / alarms. Too many starts / stops may damage the equipment. It is better to simulate the engine running, if possible.
2. some trips require specialized equipment, a technician attendance is advisable.
3. some set points are having "hysteresis". Especially, the analog buttons when fixed back in the initial position are set on a "new" value. (For instance the under voltage in the MSB).
