Temperature management active
The device has an active temperature man-
agement to protect it from damage due to
too high inside temperatures. In case of a
temperature rise above the
fi
xed limits, the
modulation is reduced linearly. To prevent
the complete system being switched off ex-
ternally (in this operation permissible for the
controller) in case of reduced operation due
to too high an internal temperature, no fault
message is sent via the relay.
With a drop in temperature the modulation
rises again llinear.
Check installation of the device and cooling
of the controller.

HALL-IC
Incorrect signal from the Hall-ICs, error in
the commutation.
Internal plug connection faulty.
The controller switches the motor off. Auto-
matic restart if no faults are recognised.
Replace fan / motor

is
released.
EC-Controller switches off, renewed attempt
to start after about 2.5 sec.
Final shutoff, when fourth starting test fails.
It is then necessary to have a reset by dis-
connecting the line voltage.
Check if motor is freely rotatable.

IGBT Fault
Short circuit to earth or short circuit of the
motor winding.
EC-Controller switches off, renewed attempt
to start after about 60 sec.
Code 9.
Final shutoff, if - following a second starting
test
–
a second fault detection is detected
within a period of 60 seconds.
It is then necessary to have a reset by dis-
connecting the line voltage.

ZK undervoltage
If the DC-link voltage drops below a speci-
fi
ed limit the device will switch off.
If the DC-link voltage rises above the limit
within 75 seconds, then the cotroller will
attempt to start.
Should the DC-link voltage stay for more
than 75 seconds below the limit, the device
will switch off with a fault message.
