RESTORE DEFAULT SETTINGS
To restore default settings of the controller press OK. Then con
fi
rm once again.
Note!
Restoring default values causes irreversible erase of all settings done before. Full re-
con
fi
guration of the controller is required.
In case of failure with the restore via HMI (e.g. HMI wouldn't communicate with the controller), follow
another procedure:
▪
turn off the power supply
▪
set all the addressing dip-switches to ON (remember original setting, to apply that after the
restore procedure)
▪
turn on the power supply (alarm LED should light up continuously)
▪
turn off the power again
▪
set the addressing dip switches to previous combination and turn on the power supply

ALGORHITM LPS
Algorhitm LPS indicates the speed of application execution in “loops per second”.
7. FREQUENCY CONVERTER CONFIGURATION
As the control box uses Modbus communication to control the frequency converters, it is required to
make proper con
fi
guration of those devices prior to startup of the unit.
Note!
Improper con
fi
guration of frequency converters could cause dangerous malfunctions of the
unit!
Maximum of three frequency converters can be installed with OPTIMA control box:
▪
FC for single supply plug fan
▪
FC for single exhaust plug fan
▪
FC for rotary heat regenerator RRG (see: Drive Unit for Rotary Exchanger manual)
