4.2 - Hardware Configuration
This section applies only to DCY-2057 Controllers which do not have a
pressure sensor installed in input 2. In this case, input 2 is an universal standard
analogic input which must be configured according to the explanation given below.
The software configuration input level (level 2 - Inputs) should be implemented
by a process input configuration by hardware, by means of internal jumpers.
There are four places for the installation of jumpers for channel 2: J1, J2, J3
and J4. They are located on the CPU Board as illustrated on figure 31.
Location for Jumpers 1 to 4
Table 2 indicates the jumpers to be installed for the various types of inputs.
Check the required type of input and locate the jumpers as specified. Make sure only
those jumpers corresponding to the required input are installed.
