2-12 Installation & Wiring
Keypad Wiring
Number of Keypads One or two keypads may be connected to a PS-6144 controller as shown in Figure 12.
See Figure 14 for possible system configurations.
Programming Enable The wiring connector on the back of each keypad includes terminals to select Operator
or Master level programming for that keypad. These terminals can be temporarily
jumpered during set-up to allow entry of programming access codes, or they can be
switched with a variety of devices including mechanical switches, relay contacts, and
PLC DC outputs. See ENABLE CODES in the programming section for details on pro-
gramming access.
If a solid state device will be activating the Programming Enable terminals, that device
will determine whether sourcing or sinking wiring should be used. For mechanical de-
vices such as jumpers or key switches, either sourcing or sinking wiring may be used.
