WECM are not 'smoke extraction' motors (as defined in EN 12101-3) and may not
under any circumstances be installed inside the high temperature airstream.
NOTE!
When the user activates the "Fire Mode" function, he/she acknowledges that the
protection functions of the WECM / Emerald eZA are disabled, which may result in
damages to the WECM / Emerald eZA itself, to the components connected to it, to
the environment in which it is installed and to people present in such environment;
therefore, the user takes full responsibility for the risks arising from such operating
condition. Operation with the "Fire Mode" function programmed voids the warranty
of the product. The operation in this condition is internally registered by the WECM /
Emerald eZA and must be validated by a duly qualified professional of engineering and
occupational safety, since such procedure significantly increases the operating risk.
The "Fire Mode" function is intended to make the WECM / Emerald eZA continue work under
adverse conditions, inhibiting most faults generated by the electronic in order to protect itself or
protect the motor.
The "Fire Mode" is selected by applying 10VDC to the frequency input during 5 seconds. The built-
in 10VDC source can be used. When selected, the motor will speed up to the maximum speed set
and will disable all motor software protections.
The only possible way to turn off the "Fire Mode" operation function is to de-energize the complete
solution and energize it back again.
6.7. PASSIVE POWER FACTOR CORRECTION (PFC) (OPTIONAL)
Only Equipment intended to be use in First environment that have a total rated power lower or
equal than 1kW are required to use an external passive filter (PFC) in order to comply with the
IEC 61000-3-2 and comply with the C2 requirement for Low-frequency disturbance voltage as
indicated in the 61800-3 requirements for the electromagnetic compatibility (EMC) The passive PFC
filter shall be installed in series with the line (L) power cable as shown on diagram below.
NOTE!
The end user takes personal responsibility for the EMC compliance of the whole
installation.
