The high level of accuracy permits precise modulating control of industrial process and
process heating applications, often significantly enhancing performance and product
quality.
In commercial and industrial burner applications requiring high turndown and reliable
ignition, the auxiliary switches can be applied to create separate positions for burner
light off and low fire. In dual fuel applications, additional switches can be used to create
separate high fire, low fire and light off positions for each fuel. The “economy position”
switch is used to drive the actuator to the full closed position when the burner is off.
In all applications, commissioning is simplified. Shaft and switch cam drum
disengagement clutches allow for the quick manual alignment of the actuator shaft and
switch cams. The forward/reverse toggle switch 西门子伺服电机SQM50...
