The actuator detects the end positions by means of the torque limiter and then positions itself at
mid-stroke to test its inertia in both directions of travel.
INTELLI+ determines stop positions at 0 and 100% on the basis
of the closing mode setting and the actuator inertia.
The display shows the stroke travel distance at the end of the
set up process
Turn to OK to confirm and return to control mode.
15 POSITION SIGNAL AND POSITIONER
Position signal
Some actuator configurations can incorporate an analogue position signal.
No prior set up is required as the signal is automatically adjusted to the 0 to 100% positions. The
default signal is in 4-20 mA format (4 mA at 0% and 20 mA at 100%)
2 or 3-wire connections.
See §25 for further details and information on analog signals.
Positioner
Some actuator configurations can perform control functions in response to a control signal
(e.g. 4 – 20 mA). No prior set up is required as the signal is automatically adjusted to the 0 to 100%
positions.
To check positioning locally, local control has to be configured for proportional
control from 0 to 100%. When this setting has been completed, return to the
local control mode.
The display shows the opening position and the command in %.
Adjust the control value up or down with the blue button and ensure that the actuator adopts
the position required.
