5. OPERATING THE ICON 2000
5.1 OPERATION BY HANDWHEEL
To operate the actuator by handwheel, press
the lever and at the same time rotate the
handwheel until the clutch is engaged. Release
the lever and move the valve by handwheel. The
actuator will return to electrical operation only
by energizing the motor.
WARNING
Do not manually operate the actuator with devices
other than the handwheel and the declutch
lever. Using cheater bars, wheel wrenches, pipe
wrenches, or other such devices on the actuator
handwheel or declutch lever may cause serious
personal injury and/or damage to the actuator or
valve.
5.2 ELECTRICAL OPERATION
Before connecting power to the actuator check
that the voltage is correct and according to the
indications on the nameplate. Wrong power
supply could cause a permanent damage to the
electrical components. Check of phase rotation
is not necessary since the unit is provided with
automatic phase rotation correction. Place
the 3-position selector in OFF and then switch
on the power. Do not operate the actuator
without first checking that the configuration is
according to the required application. Using
the “VIEW and SET-UP” features can do this
(seeparagraph 6.4, Local controls - Entering
the set-up mode).
5.3 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-energized.
If “latched” was selected, as the OPEN or
CLOSE push-button is pressed the motor is
energized, and it runs on after the control 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.
According to the position of the local selector,
the OPEN/YES and CLOSE/NO push-buttons
work as follows:
- Open/Close commands if the selector is in
Local position.
- Yes/No, to answer prompts in the menu, if the
selector is in Off or Remote positions.
OPEN/YES
STOP
CLOSE/NO
