In order to perform automatic calibration, the cams should be adjusted to contact the
switches in positions where the valve is fully open and fully closed.

• Restart in Protection Mode
Proportional electric actuators automatically protect themselves when exposed to
excessive torque or high temperature. When the actuator protects itself, it activates the
fault relay and illuminates the leds on the control card according to the fault mode to
indicate which of the over torque or high temperature protections. The actuator can be
restarted by following the steps below after the failures related to over torque protection
or high temperature are eliminated.
1) It is taken into manual control over PCB board,
2) Valve clamping is eliminated, if any, by manual control with OPEN CLOSE keys or hand
wheel.
3) Protection is exited by holding down the SET and CLOSE keys simultaneously for 5
seconds,
4) By holding down the SET, OPEN keys simultaneously, the leds are expected to light
up (green - yellow - blue - red) respectively. When the leds are lit, automatic calibration is
started and automatic calibration is performed.
d. Meaning of LED Lights
There are two different led groups on the actuator control board, RGB1 and sequential.
These LEDs light up in different patterns for operation, orientation and information.
The table below contains the meanings of the leds. S in the table refers to sequential
combustion and F flashing.
blue and green, and will light green in the fully closed position.
Then it will open. The RGB1 led will flash red and blue during the opening process, and the
RBG1 led will light red in fully open position. When the calibration process is completed
successfully, the leds will turn off one by one and the calibration will be completed. Thus,
the proportional electric actuator will detect in which angle range it operates and will
provide a smooth control. If the automatic calibration process is interrupted for any
reason, please calibrate it from the beginning.
