4.12.6 Proportional Band
Proportional band is the range of errors between position and demand signal that will produce reduced speed (pulsing).
Default = 15%
To change from the default, select “NO” until the required value is displayed. The value is adjustable between 1% and
100%, in 1% increments.
4.12.7 Deadband
Default = 2%
The deadband should be wide enough to prevent “hunting” of the actuator but as low as possible to give adequate
response to changes in the error signal.
To Change from the Default Range:
Select “NO” to adjust the value between 1% and 50%, in 1% increments to suit the application.

4.12.8 Comm Loss Delay
Default = 60 sec.
The User may select the amount of time delay before communication loss is flagged to the network. This selection is
configurable from 120 seconds.
4.12.9 Comm Loss Action
Default = None
The User may select what action the actuator should take when network communication is interrupted. This action is
configurable as Close, Open, Stop, Position.
4.13 HART Option
HART option enables the actuator to be controlled by a Highway Addressable Remote Transducer communications signal.
If the option is purchased, it is automatically enabled. The device address is fixed for point-to-point connection, but must
be set by customer for multi-drop topology.
NOTE: If the HART option has not been purchased, the screens for changing HART will not be available. To add the HART
option, please consult Limitorque service at (434) 528-4400.
The MX is equipped with the ability to either hardwire to digital inputs for control, set-up for analog control (Modutronic),
or control via network protocols. In order to utilize this feature, select “Multi-control mode” operation located in Section
4.16, Remote Mode. This is the default setting for remote control. There are three modes of remote control when remote
mode is configured for multi-control: digital control, analog control, and network control. Digital and network control
operation is based on the last command received. Analog operation is initiated be either toggling user input 2 (configure
for CSE input) or breaking and reapplying the analog control signal.

4.13.1 Status
Default = ON
HART Status enables user to change from the default condition to turn on and off the digital control capability of
the actuator.
4.13.2 Multi-drop
Default = Disabled
MULTI-DROP (ENABLED) or (DISABLED) allows the user to select the desired network topology. To change the setting,
select NO until the required option is displayed. Select YES if the setting is correct to go to the next display.
NOTE: Changing the topology also requires that the network be wired correctly for the selected topology.
