IND560 PDX Installation Manual
When both SW1-1 and SW1-2 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 IND560 PDX Technical Manual,
Chapter 4.0, Service and Maintenance.

Discrete I/O (Relay) Switch

A switch on the Relay Discrete I/O board selects if for active or passive inputs. An
explanation of these two modes and sample wiring diagrams were provided earlier
in this chapter. 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
2-60.
