8 ACTUATOR OPERATION
8.1 Actuator local controls
For EFS "standard" version
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-energized. If
"latched" was selected, as the OPEN or CLOSE
push-button is pressed the motor is energized,
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.
8.2 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 percentage value, according to the
configuration. Two LED’s indicate the actuator
position/operation, while a third LED indicates
alarms.
