Section III. I/O Configuration
Basic I/O Configuration:
The unit requires configuration of the I/O’s to accept any inputs. A pre-wired configuration plug is
provided which has to be plugged into connector labeled 11 through 20. It allows the use of standard
AMADA WELD TECH foot switches and weld heads without further configuration.
For other configuration methods please refer to
Modification of I/O Configuration on page B-6.
Input Section Example
This unit employs bi-directional opto-isolators
which allow the user to configure the inputs to
sink current, i.e. +24 VDC active, or source
current, i.e. 0 VDC active. A typical input section
is shown on the right.
See Modification of I/O Configuration on page B-
6 for both complete input sections.
Factory Configuration Plug
The factory default setting is 0 VDC active and is
set by connecting the
CONFIGURATION
plug into
I/O connector labeled 11 through 20. The plug’s
internal wiring is shown on the right.
