6.5 - FIRE MODE FUNCTION (OPTIONAL)
DANGER!
Notice that the WECM / Emeral eZA is just one of the components of the ventilation
system, and it is configurable for different functions, including the "Fire Mode"
function;
Thus, the full operation of the "Fire Mode" function depends on the accuracy of the
project and on the joint performance of the components of the system;
Ventilation systems that work on life safety applications must be approved by the
Fire Department and/or another competent public authority;
The non-interruption of the operation of the WECM / Emeral eZA, when configured
for operation in the "Fire Mode" function, is critical and must be taken into account
in the preparation of safety plans in the environments in which they are installed,
since damages may occur to the WECM / Emerald eZA itself and to other
components of the ventilation system, to the environment in which it is installed
and to people with risk of death;
The operation in the "Fire Mode" function may, under certain circumstances, result
in fire, since the protection devices will be disabled;
Only personnel from engineering and safety must consider the configuration of the
equipment for the "Fire Mode" function;
WEG strongly recommends to follow the cares and procedures above before using
the WECM / Emerald eZA in the "Fire Mode" function, and it will not be liable to
the final user or third parties for any losses or damages direct or indirectly incurred
due to the programming and operation of the WECM / Emerald eZA in "Fire Mode"
regime, considering the critical and special use of this function.
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. 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.
