3. Local control
After configuring the actuator, if no alarm is present, place the 3-position selector in LOCAL
and control the actuator by OPEN, CLOSE and STOP push-buttons.
If “push-to-run” was selected the actuator can be driven to the desired position by pressing
and holding the OPEN/YES or CLOSE push-button. As the push-button is released, the
motor is de-energised.
If “latched” was selected, as the OPEN or CLOSE push-button is pressed the motor is
energised, and it runs on also after the push-button is released. To stop the motor, press
the STOP push-button. To reverse the direction, press the STOP push-button and then
press the push-button relevant to the opposite direction.
In “latched with instant reverse” mode, the local controls work as in the “latched” mode, but
to reverse the motor direction you only need to press the push-button relevant to the
opposite direction.
4. Local indication
The upper display indicates the valve position as a percentage of opening (open = 100%).
The lower display has two alphanumeric lines.
The upper line indicates the actuator status and the 3-position selector status. The lower line
indicates the actuator operation, or the position request % value, according to the configuration.
Two LED’s indicate the actuator position / operation, while a third LED indicates alarms.
