Controller
Our VdS Controller is always manufactured in a monitored version at the Karben site.
Control panels for all applications.
Our controller is built in a control cabinet housing made of steel, designed for protection class IP 54, and painted according to industrial standards.
Controller for diesel-engine-driven fire pump units:
- Ammeters that indicate the charging rate and voltmeters that indicate the voltage of the two starter batteries
- Voltage monitors integrated in both battery charge controllers, which briefly interrupt the charging of the battery approx. every 30 minutes to record and check the state of charge, serve to automatically maintain the charge of the two battery sets
- Battery undervoltage, any malfunction of the control voltage, the charge controller or the fall of a circuit breaker is indicated by a red LED on the charge controller
- Monitoring relay / switching amplifier monitors the pressure switch lines for wire breakage and short circuit
- Oil pressure gauge indicating the correct oil pressure of the diesel engine
- Hour counter and rev meter as well as cooling water temperature indicator
- Two emergency start test buttons and two additional emergency start buttons with sealed protective cap
