4.2 - Hardware Configuration
The input level configuration by software (level 2 - Inputs) should be implemented
by a process input configuration by hardware, by way of internal jumpers.
There are four places for the installation of jumpers for channel 1: J5, J6, J7 and
J8; and also four places for the installation of jumpers for channel 2: J1, J2, J3 and J4.
They are located on the CPU Circuit Board as illustrated on figure 33.
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.
