1615 actuators are uniquely suited for both industrial and commercial applications. 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 "closed 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 in combination with the auto/manual selector switch provides direct manual control.

DESCRIPTION
North American model 1615 reversing actuators/control motors are used for the positioning of flow control valves, butterfly valves, dampers, or any application requiring rotary motion. The 1615 actuators accommodate control input signals of 4-20 mA, 0-135 Ω, 0-10 V dc, 0-20 mA, position proportional and floating control. The available output signals include 4-20 mA, 0-135 Ω, 0-10 V dc, 0-20 mA, and 0-1000 Ω. 1615 actuators have easily accessible and adjustable auxiliary switches. 1615 Actuators provide a variety of functions including auto/ manual selector switch, manual forward/reverse toggle switch, zero and span adjustment, parallel or master/slave operation, split range control, input signal override, and selectable electronic linearization. The 1615 is engineered for precision. It is particularly well suited to applications requiring a high degree of modulating accuracy and repeatability. Drive shaft play is limited to 0.3°, with a modulating accuracy of 250 repositions through 90° of travel. The 1615 actuator may be mounted in any position. Two types of optional mounting brackets provide installation flexibility and allow for the simple replacement of Honeywell and Barber Coleman actuators.
