MOUNTING NOTE: Connection leads must not touch piping (heat transfer). Fig. Mounting / installation positions When the operating current is applied, a PTC resistor heats up a wax element. After a delay, this wax element expands, causing stroke movement. 3 EN0B-0490GE51 R0709 MT SMALL LINEAR THERMOELECTRIC ACTUATORS Position Indicator The position indicator (the red indicator behind the window on the face of the actuator) shows the model's type of action (NO or NC) as well as the current stroke position.
