, Dragon8 monitors and records the minimum and maximum values of these
quantities:
• Battery voltage
• Capacitor voltage
• Motor current
• Motor speed
• Controller temperature
Two instances of the operational monitoring log are maintained. Service engineers can access and clear
the first log; the second is accessible and clearable only by Sevcon engineers. The Customer copy is
normally recorded and reset each time the vehicle is serviced. The Sevcon copy records data over the
controller’s entire working life.
