DRV-100
DIESEL SPEED DETECTION DEVICES AND MAGNETIC PICK-UPS
Over-speed relay from the pick-up signal.FUNCTIONING
The device uses a magnetic transducer (pick-up type TM90-...). To detect he speed of an engine which has two thresholds inside; one that can be adjusted by the user,which is the "ENGINE RUNNING" threshold,and the oder which is fixed at a very low number of revolutions,and which represents the stationary engine threshold. At the moment when the devive is supplied,the output D+ is negative (-). When the device detects that the engine is running,the output D+ moves from negative to positive (+). Indipendently,a second output W supplies a frequency that is similar to that found on the W terminal of a pre-excitation battery charge alternator (normally used as a revs counter). When detection has occurred,a green indicator located on the device lights up. The situation remains like this up until 4 seconds after the speed has fallen below the "STATIONARY ENGINE" fixed threshold,in other words only when the engine is clearly stationary. |
