Heated spray nozzles
With terminal 15 ON, the spray nozzle heating is switched on and off based on the outside temperature transmitted via the K-bus . in order to prevent the spray nozzles freezing up dependent on the outside temperature. A control unit activates and monitors the spray nozzles.
Spray nozzle heating cuts in at:
ON |
Outside temperature < 3 °C with hysteresis 3 °C |
Terminal 30 > 12.2 V and driver in working order |
OFF |
Outside temperature > 3 °C with hysteresis 3 °C |
Terminal 30 < 11.4 V or driver with defect |
