C&C Mode Switch Options
There are two C&C mode switch configurations:
1.
A standard C&C corner switch assembly (P/N 845900-018) that fits into one corner of the Display Head’s
housing (see Figure 38). To enter C&C mode, remove the corner bolt from the Display Head’s cover. To exit
C&C mode, replace the bolt.
2.
A standard front panel C&C switch for the Remote Display Head (ref. Figure 34 on page 42).
Installing Optional Keypad Kit - Right or Left Side
Figure 38 shows the installation and wiring of the optional keypad. To attach the keypad housing mounting screws,
you will need to pull/slide up the display assembly away from the Display Head. Insert the keypad wires through
the center hole in the gasket, slide the gasket down against the keypad and align its three holes with the mounting
holes in the keypad. Hold the keypad against the Display Head and screw in the 3 mounting screws, replace the
display assembly and then connect the keypad wiring to the terminal block as shown in Figure 38. The screws are
self-tapping. The user may want to pre-tap the holes using the screw to ease installation.
