Resticted Menu Routines
Section 3: Restricted Menu Routines
3.3 Voltage Span
This function allows to recalibrate the sensor that measures the main voltage supply.
The recalibration procedure is as follows:
Using a multimeter, measure the value of the voltage supply on terminals L1/L2 of the terminal
board. On the actuator display, enter the same value measured by the multimeter and then press
YES. The new value is accepted only if it is at least 1 V different from the previous value. Pressing
YES will not effect any change in voltage sensor calibration if the value indicated on the display is
not changed.
3.4 1 P.man
This function is also known as "Gear Relaxation," and functions by backing off the motor a small
amount at either end of the valve travel. The effect is to reduce compressive stress on the actuator
gears and facilitate engagement of the manual override declutch lever. This routine is set in-house.
Standard value = DISABLED.
3.5 HW Config
This function is used to select the fieldbus control option. The following options can be selected:
• Base (No bus control)
• Lon (Lonworks)
• Mod-bus (Modbus RTU)
• Prof-V0 (Profibus DPV0)
• Mod-m (Modbus RTU)
• FF (Foundation Fieldbus)
• Hart (Hart)
• Prof-V1 (Profibus DPV1)
• Prof-V1r (Profibus DPV1 redundant)
• MOD-Dw (Modbus Dewa)
• Prof-V2 (Profibus DPV2)
• Prof-V2r (Profibus DPV2 redundant)
If the “base” option is set, then a fieldbus interface card is not required. If one of other options is
chosen, the ICON3000 base card must be equipped with the appropriate bus interface card. It is also
necessary to set the parameter “bus protocol” that sets the type of communication protocol
between the base card and the bus interface card. The “BUS” routine appears in the ACTUATOR
SETUP menu and the relevant parameters (node address, baud rate, etc.) can be viewed and changed
as described in the ICON3000 IOM. If the option LONWORKS is chosen, the “BUS” routine in the
ACTUATOR SETUP menu changes to "FDI CONTROL."
