Status indicators
Open circuit
Indicators shown on the right light up, VRD indicator flashes red
Cause:
Output voltage is greater than 110V
Remedy:
Switch machine off and on again;
if fault keeps recurring, have device serviced
Mains undervoltage or mains overvoltage
Indicators shown on the right light up, VRD indicator flashes red
Cause:
The mains voltage is outside the tolerance range
Remedy:
Check mains voltage, switch machine off and on again; if
error keeps occurring, have machine serviced
