15V outside limits
Test load does not match
Motor error codes
Motor parameters out of range
Thermal protection active
Invalid model selected
Probable cause
Low load detected. Pump is running dry.
Motor might be faulty or viscous medium is
present.
Circuit is too hot and power was reduced to
less than 2/3 of rated power.
Circuit is too hot to run, pump stopped
Hardware overcurrent protection triggered.
Line voltage is too high
Line voltage is too low for proper operation.
Power correction circuit current cannot be
controlled
Average motor current was too high, pump
load is much higher than expected
Electrical circuitry did not pass self‐test.
One of the display segment diodes is faulty
(open/short)
Display board does not detect proper
connection to main board, but power supply
is present
Voltage on DC link shunt (R34) not in
expected range
During MFG. TEST, this is 10 kΩ, 1% resistor
for 10 °C..30 °C During operation, expected
values are ‐55 °C..150 °C
During MFG. TEST, this is 0 °C..50 °C. During
operation, expected values are ‐55 °C..150
°C
Comparison between internal references
does not match
15V supply is not 15V.
No test load detected or current
measurement does not work properly (MFG.
TEST)
Motor does not behave as expected
Motor temperature is too hot to operate.
Pump model not valid or out of reach
