Master/slave function
When the switching input is connected to 18a and the pressure controller is
deactivated, jumper J4 can be used additionally to re-connect the swivel angle
command value input from inputs 14c (+) and 16c (-) to connections 18c (+) and
20c (-).37
This reduces the wiring effort for a master/slave circuit (see chapter 5.12 "Master/
slave operation" on page 34. The master/slave function can be deactivated at
any time during operation.
Activation/deactivation of pressure controller OFF and master/slave function
Function PLC-in pin 18a
Pressure control ON/OFF
Master/slave ON/OFF
Factory setting: J4 not set
Attention:
The function of pressure limitation is no longer effective when the pressure
controller is deactivated!
Depending on the variant, the analog input with connections 18c(+) and 20c(-) is
used for different purposes.
Version without power limitation (VT 5041-3X/1... or VT 5041-3X/2...)
For the master/slave operating mode, the actual swivel angle value of the master
can be read in at this input. When the "slave" operating mode is activated (by
means of switching input 18a) the input is automatically connected to the swivel
angle controller, and the pressure controller is deactivated. The pump is then
operated exclusively under closed-loop swivel angle control.
Version with power limitation (VT 5041-3X/3...)
With the variant of the VT 5041-3X with power limitation, the analog value is taken
as power command value. For further notes on power limitation, please read
chapter 5.11.9 "Power limitation (VT 5041-3X/3... only)" on page 33.
If control electronics VT 5041-3X is installed as replacement for VT 5041-2X in an
existing system, jumper (J8) must always be set.
For new systems, the jumper must be configured depending on the type of
wiring. More details can be found in chapter 7.6.4 "Connecting the valve position
transducer" on page 55.
This setting option is provided for reason of compatibility with control electronics
VT 5041-2X. If control electronics VT 5041-3X is to be used as substitute for VT
5041-2X, it is possible to select the same gain as with the control electronics of
series 2X.
Jumper J11 assumes the same function on both control electronics (series 2X and
3X).
Together with switches S3.7 and S3.8 these jumpers can be used to change
the gain of the pressure controller. More details are explained in chapter
8 "Commissioning" on page 59.
Factory setting: J11 set
The jumper must not be set irrespective of the application at hand and for reason
of compatibility with control electronics VT 5041-2X.
Jumper J16 can be used to connect the 0-V reference for the actual pressure value
signal to 10c (= reduced wiring effort).
