Once all the START, GOLDEN START and FGR START positions have been entered, the message ‘Set
HIGH Position’ will appear. Press and drive the servomotors (and VSD if optioned) to the HIGH
position by opening the air damper and fuel valve some degrees alternatively, so that more fuel is added
gradually.
It is not possible to enter the HIGH position higher than the OPEN position. The servomotors must be driven
0.5°
up/down from the previous point initially, before entering the next point, the fuel. Press to
store this HIGH position.
WARNING: IT IS THE RESPONSIBILITY OF THE COMMISSIONING ENGINEER TO ENSURE THAT THE
FLAME IS SAFE AND THERE IS A GOOD COMBUSTION AT ALL TIMES DURING COMMISSIONING.
