4.3.5.2 Setting SW6 Input Switches
SW6 switches 1, 3, 4, 5, 6 define input type
In a recorder model having a display and keypad the input switches at SW6 must be set to match the type
of input to be used. The location of SW6 is shown in Figure 4-3. The appropriate switch settings for the
various input types are shown in Table 4-3.
Note that the setting of switch 2 in SW6 is not related to input type. It is used, along with the “BRNOUT”
parameter in the input group, to specify the effects of an input failure as described in Subsection 4.3.5.3.
ATTENTION
The ON position for SW6 switches is toward the left side of the printed circuit assembly (when
facing recorder.)
