3 Product overview
3.1 Application operational area
The fans / motors are not ready-for-use products, but conceived as components for
ventilation systems (type designation see rating plate). The fans / motors may only then
be operated when they are installed in accordance with their intended use, and safety
has been secured through protective devices in accordance with EN ISO 13857 (EN ISO
12100) or other structural protective measures.
Attention!
•
They must not be used in hazardous areas for the transfer of gas, mist vapours or
mixtures. Nor must they be used for the transfer of solid components in the transfer
medium.
•
If the motor/fan is used in applications where a ignitable atmosphere can form in the
event of a fault, e.g. due to leakage, the user must assess the risks of ignition and take
appropriate precautions to prevent ignition.
3.2 Functional description
ECQ
motors from ZIEHL-ABEGG are highly e
ffi
cient, electronically commuted motors
(EC) with an integrated controller. They are designed exclusively for driving axial fans.
The motors are designed for continuous operation (S1-operation) and are thermally
protected.
Depending on version motors with a
fi
xed speed or motors with three speeds (
rating
plate).
Motors with three speeds
•
Three pre-programmed speeds are possible (
rating plate) which are activated
depending on the connection of the additional control input at
“
L1
”
or
“
N
”
.
•
With the
“
Motor Programmer
”
(accessory) and a PC with the appropriate software,
individual speeds and the rotation direction can be programmed.
Possible rotating directions
•
CCW (counter-clockwise rotation) = left-hand direction of rotation looking at the motor
shaft
•
CW (clockwise rotation) = right-hand direction of rotation looking at the motor shaft
3.3 Motor protection
The motor has devices to protect it from overloading, these include protection in case of
blocked rotor and overload protection with running motor.
On exceeding the maximum permissible operating temperature, this can lead to stopping
of the motor and can cause permanent damage!
