Fire mode function:
Electronics are equipped with Fire mode function. In this case
electronics runs as emergency controlled unit, (for example: extract the smoke from a burning
building), with disabled protections and functions.
In fire mode case:
Overheating protection - disable,
Under voltage protection - disable,
Start/Stop function
– ignore,
Set RPM via AN1 or Potentiometer
– ignore,
Set RPM via AN2
– ignore,
Phase overcurrent
– disable,
Controller error detection - disable.
In Fire mode function electronics runs with Fire mode set parameters. These parameters
should be sets via Modbus registers. The function should be enabled by disconnect the
terminal pins (16) and (17). We recommended purpose switch. For disable the function
disconnect terminal pins (switch=ON).
Fire mode function can be also enabled via Modbus communication. For additional information
about activating fire function via Modbus, see the chapter 7.
Electrical parameters
: Operating voltage = 24V, Zin=10kΩ
Note!
Fire mode function is useable only for protection in case of a burning
building, to extract the smoke from it. In normal condition the fire
mode function is not allow to be used. In this case Domel is not
responsible for damage to the controller caused by improper use.
Star/Stop function:
Electronics are equipped with Start/Stop function. If the controller has all
conditions for running, the motor goes runs when the terminal pins (18) and (19), are
connected together.
