Space heater
A space heater can increase the internal temperature and keep dry inside actuator to avoid the freezing lubricant and moisture causing actuator failure under low temperature or high humidity. Heater is not recommended if the ambient temperature is above 35℃/95℉. However, when the temperature varies much from day to night or between summer and winter, heater and thermostat (25±5℃/77±9℉) are recommended.
Heater thermostat
The option can switch the heater off when the temperature inside the actuator is over 25±5°C (77±9°F).
Additional limit switches
The standard model equips with the 1st & 2nd switches for fully-open and fully-closed. The option consists of the 3rd & 4th auxiliary switches which provide dry contacts for fully-open and fully-closed.
Floating controller
The actuator can be controlled by external controller to open, close and stop at any position between 0 and 90 degree and will fail clockwise to the end position on loss of power. (Based on the standard running direction that the actuator fails clockwise on loss of power.)
The picture is based on AC 110/220V
Modulating controller
Actuator can be operated according to input signal and provide the output signal for feedback.
Input signal：4-20mA，1-5V，2-10V
Output signal：4-20mA，2-10V
The picture is based on AC 110/220V
Operating direction
Standard : Fail clockwise on loss of power.
Optional : Fail counter-clockwise on loss of power.
Manual override
Thermal insulation blanket
Thermal insulation blanket ensures actuator operation under high temperature; its jacket design allows easy removal and reinstallation.
