CONFIGURATION AND FUNCTION
HIGH-PERFORMANCE INTELLIGENT MODULE GROUND
POE’s unique circuit design，all imported industrial-gradeelectronic components,uses an intelligent signal acquisition andcontrol module with an industrial single-chip microcomputer asthe core, and integrates signal acquisition,processing,feedbackand control. Adopt advanced hybrid integrated circuit,goodstability, control accuracy up to 1/1000.
Small size,easy installation and simple operation.
Each POE series actuator comes with a handle when it leavesthe factory.If there is a power failure in the field control, you candirectly insert the handle into the manual operation port to drivethe valve. When not in use, you can remove the handle and storeit separately; Fasten with screws.
ELECTRICAL AND MECHANICAL LIMIT FUNCTIONS
Electrical stroke limit function: When the actuator reaches the fullyopen and fully closed limit positions, the built-in electrical limitswitch will cut off the circuit to protect the actuator.
Output shaft mechanical limit function: When the electrical strokelimit function fails, the output shaft of the actuator will be lockedby the mechanical limit device,thereby protecting the valve fromdamage.
The picture shows the position relationship between electrical limitand mechanical limit.
OVER-TORQUE PROTECTION FUNCTION (OPTIONAL)
When the valve is stuck due to impurities, foreign matter in thepipeline or other reasons during the working process (intermediateposition), the output torque of the actuator will increase rapidly.When the set value (tripping torque) is reached, the torque switchwill The circuit is opened,protecting the valve and actuator fromdamage.
HEATING DEHUMIDIFICATION FUNCTION(OPTIONAL)
The electric cavity of the POE series actuator can be equipped with PTC electric heating elements, which are usedin places with large temperature differences between day and night and in humid places to prevent damage toelectrical components caused by condensation.The heater works continuously, so it is charged, even when theactuator is not running.
