ERROR 15<br />
An external protective device<br />
connected to terminal X1/PTC<br />
has released (e.g. PTC which is<br />
connected has reached its<br />
release temperature).<br />
PHASELOSS One phase of the power supply<br />

• Improper cooling<br />
• Contamination of the motor vents<br />
• Ambient temperature too high<br />
• Close X1/PTC if there is no external<br />
protective device connected.<br />
• Close external on/off switch if<br />
connected to these terminals.<br />
• For detailed information, see<br />
chapter 8.4.3.<br />
• Check power supply under full load.<br />
– Check if phase failure at the input.<br />
• Check circuit breakers<br />
• Visual inspection of points at the<br />
input terminals.<br />
• Supply voltage too low<br />
UNDERVOLTAGE DC voltage • Phase failure at the input<br />
• Asymmetry of the phase imbalance<br />
COMM LOST<br />
Reset:<br />
• Check if the addressing of Basic<br />
Inverter [DIP SW.] has been done<br />
The communication between correctly.<br />
the Power Unit and the control<br />
• Check if each unit has its own pump<br />
card is lost. address.<br />
• Check if the connection from<br />
control card to the power unit is<br />
made properly (ribbon cable).<br />
• Cut off power supply for > 60 seconds.<br />
• <strong>Manual</strong> reset by closing external ON/OFF (Terminals X3/7-8)<br />
• <strong>Manual</strong> reset by pressing and simultaneously for about 5 seconds<br />
• Auto-reset possible if ERROR-RESET [0615] is set to ON
