4.1.4.7 Aarding van de CTR-bus
Alle Regelaars worden met behulp van een twee aderig afgeschermde kabel in een
ring (CTR-bus) met elkaar verbonden (zie fig. 4.5).
De CTR-bus moet altijd op één punt aan aarde liggen. Dit gebeurt door het plaatsen
van een jumper.
Op slechts één Regelaar in de bus wordt de jumper geplaatst (deze jumper kan alleen
op een
Bedieningsregelaar worden geplaatst).
Handel als volgt:
1. Verwijder de kleine afdekkap.
2. Leg de CTR-bus aan aarde door het plaatsen van de jumper over de pennen
boven de klemmen A en B (zie fig. 4.5).
3. Monteer de kleine afdekkap.
