A2.1.2 THERMAL PROTECTION FUNCTION
The pump is equipped with a thermal self-protection mode.
If the fluid temperature exceeds the maximum value at a specific
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 fluid 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.

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/flashes 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).
