Condensation warning, indicates that the
inverter (water) temperature is lower than
expected ‑ possible causes include inverter
water valve stuck open.
Indicates that the inverter temperature is
higher than expected ‑ possible causes
include no or low cooling water flow, inverter
water valve stuck closed or water pipe to
inverter is blocked.
Controller temperature above the upper
limit/controller temperature sensor open
circuit. Check water supply.
Inverter heat‑sink temperature above the
upper limit/inverter heat‑sink temperature
sensor open circuit. Check water supply.
Motor temperature above upper limit/motor
temperature sensor open circuit. Check
water supply.
The loss of one of the three input phases has
been detected. Check the mains supply to
the drive or blown fuses.
The upper controller temperature regulator
active - current limit reduced. Check cooling.
Upper heat sink temperature regulator is
active - current limit reduced. Check the
cooling.
Reserved
Lower voltage regulator active. Check the
mains voltage.
