7.1.11 ESD DI-4/Net Disable (Parameter 14)
This input determines the mode of operation for the ESD/DI-4
remote input. The input can be used either to disable control
of the actuator from the network, or to act as an ESD/digital
input. When this setting is made ‘Active’ the input will disable
network control of the actuator when the contact input is
closed irrespective of the Aux Mask setting.
Please consult the Rotork manual for more information.
7.1.12 Redundancy FR/SR Mode and Simple/RedCom
Mode (Parameter 15)
When using either type of dual channel card there are
two methods for redundancy that can be used, Flying
Redundancy, where the two channels have addresses 64
apart, and System Redundancy, where they have the same
address. The first bit of this parameter selects the type of
redundancy to be used. The way that data is reported can be
altered and the second bit selects either Simple redundancy
where there is no extended diagnostics message, or fully
RedCom compliant redundancy that includes the RedCom
extended diagnostics messages.

7.1.13 Partial Stroke Position (Parameter 16)
This parameter sets the position to travel to when a Partial
Stroke command is carried out. The partial stroke can be
initiated from either the open or the closed position of the
valve. The target position can be any value in the range
1-99% where 1 % is near the closed position. Note that the
desired value to which the actuator is required to move must
be outside the deadband setting.
7.1.14 Partial Stroke Limit and Timeout (Parameter 17)
This parameter is used to set two values. The most significant
bit in the register is used to determine the starting position,
which can be either the open position (1) or closed position
(0) for the valve. The remaining 7 bits are used to set the time
limit before which the required position (set by parameter 16)
must be achieved if the test is successful.

7.1.15 Actuator type (Parameter 18)
This parameter allows the identification of the type of
actuator in which the PFU is fitted. This can be useful on
some systems to allow the correct display and controls to be
enabled.
