Fade-out partial range
GasSettings

Parameter Load Mask out can be used to fade out part of the load range,
which could lead to operating problems due to site conditions. On dual fuel burn-
ers, the partial range for each fuel can be set separately. The faded-out partial
range can be driven through but not started directly. The burner drives from the
bottom to the lower limit and passes through the partial range only when the load
setpoint reached the upper limit. From the upper range, the burner remains at the
upper limit and drives through the partial range only when the load setpoint has
reached the lower limit.
Lower limit partial range:
Parameter LoadMaskLowLimit determines the lower limit. The lower limit can
not be set above the upper limit.
Upper limit partial range:
Parameter LoadMaskHighLim determines the upper limit. The upper limit can
not be set below the lower limit.
