Indicator LEDs
• Run/Fault signal LED (item 8, Figure A2-1)
- LED is GREEN when pump is running in normal pump
operation.
- LED lights up red/ashes when there is a fault (refer to
Section A2.2).
• Control mode display LEDs (item 9, Figure A2-1)
• Pump curve display LEDs (item 10, Figure A2-1)
• LED combinations are used to indicate when the following
functions are in operation:
- Pump venting (refer to Sections A2.1.5 and A2.1.6 for
information on how to activate this function).
- Manual restart (refer to Sections A2.1.5 and A2.2 for
information on how to activate this function).
- Key lock (refer to Sections A2.1.5 and A2.1.6 for
information on how to activate this function).
A2.1.2 THERMAL PROTECTION FUNCTION
The pump is equipped with a thermal self-protection mode.
If the uid temperature exceeds the maximum value at a specic
ambient temperature, e.g. 90°C at an ambient of 62°C, the pump
will automatically reduce the power consumption, reducing the
speed and performance of the pump.
In this condition the Run/Fault signal LED will be blinking RED.
When normal temperature conditions return the pump will
automatically revert to normal operation.
If the uid temperature increases further, the thermal protection
function may stop the pump temporarily.
In this condition the Run/Fault signal LED on the pump will be
constant RED until normal temperature conditions return.
