•PressYEStochangethemonitor
relay or NO to change auxiliary relays
AS1, 2, 3, 4, 5, 6, 7, 8.
Monitor relay
•PressYESorNOtoenableordisablethe
following situations from the conditions
which de-energize the monitor relay: motor
over-temperature, over-torque, jammed
valve, manual override, ESD signal on,
low lithium battery (if present), local STOP
pressed, LOCAL/OFF selected.

•PressNOtoanswerprompt
“MONITOR RELAY change?”.
•PressYEStochangeAS1,pressNOtoselect
the other relays.
•PressYESiftheconditionassociatedtoAS1
relay is correct, press NO to scrolls the list of
conditions and press YES to set.
•PressYESorNOtoeitherconfirmorchange
the type of contact when the condition
occurs (break, make). Since relay AS8 is
change-over, this option is not available.
•PressNOtopasstoAS2andthenrepeatthe
procedure for the other relays.
•PressNOtoexit.
9.1.7 Positioner
The positioning function is only available in
inching or modulating ICON 2000 actuators
and allows to position the valve according to a
“positionrequestR%”commandsignal.
The positioning function compares the present
actuatorposition%withthepositionrequest
R%,andifthedifferenceisgreaterthanthe
dead band the actuator is driven to reach the
new requested position.
The“positionrequestR%”signalmayeitherbe
received from the bus or the 4-20 mA analog
input. If the ICON 2000 is set to receive the
positionrequestR%fromthebus,afieldbus
interface card must be present, or a Hardware
alarm will be generated. If the ICON 2000 is
settoreceivethepositionrequestR%from
the 4-20 mA generator, the Ain/Aout card
must be present, or a Hardware alarm will be
generated.
The following options can be configured via
local operator interface:
- Dead band: configurable from “position
resolution%”to25.5%ofthemaximum
position error. The configured value should be
great enough to avoid the hunting effect.
- Polarity of the 4-20 mA position request
signal: it allows to reverse the relationship
between the 4-20 mA input signal and
the“positionrequestR%”,accordingto
the following diagrams. The option is not
available when the ICON 2000 is set to receive
the“positionrequestR%”fromthebus.
- Motion inhibit time: it allows to adjust the
length of the delay time between two cycles
of the motor. It can be configured from
1 to 255 secs and allows to set the maximum
number of start/hour of the electrical motor.
-%MINand%MAX,4-20mAinputsignal
range: it allows to change the relationship
between the input signal and the position
requestR%.Thisfunctionisusefulwhen
a single 4-20 mA signal is used to control
the position of 2 valves (e.g.: split range
applications). The option is not available when
the ICON 2000 is set to receive the “position
requestR%”fromthebus.
