Discrete I/O Switch; Pcb Jumper Positions - Mettler Toledo IND246 Guide D'installation

IND246 Terminal Installation Manual
When both SW1-2 and SW1-4 are positioned ON and AC power is applied to
the terminal, a Master Reset function will be initiated. This procedure will erase
all programming in the terminal and return all settings back to factory default
values. This process is described in the IND246 Technical Manual, Chapter 4,
Service and Maintenance.

Discrete I/O Switch

A switch on the Discrete I/O board selects if the inputs will be active or passive.
Refer to the Discrete I/O Connections section starting on page 2-16 for an
explanation of these two modes, and sample wiring diagrams. Ensure that the
switch is set properly before wiring to the inputs. The location of the switch and the
active/passive positioning are shown in Figure 2-32.

PCB Jumper Positions

There are no jumpers on the Main board or any of the option boards in the IND246
terminal.
