4.5 System Power Wiring
Wire the system power.
1. Connect a 16 to 30V dc source to controller terminals #1 (V+) and #2 (V–).
2. Connect a good earth ground to terminal #3.
A good earth ground is important for providing electrical and RF noise immunity to the MINI-ARRAY System. The dc power source must
supply 1.25 amps (worst case) when using the longest (6 ft) sensors. See
4.6 Gate Wiring
Connect a switched 10 to 30 V dc source as a gating input (if required) between controller terminal #11 (+) and #12 (-). Voltage is
typically switched by the open-collector output transistor of a dc sensing device.
4.7 Serial Communication Wiring
RS-485 (Models MAC-1, MACP-1, and MACN-1 only)— Connect RS-485 lines (if used) to terminals #13 (+) and #14 (-).
RS-232— Prepare an RS-232 cable using a DB-9 male connector with the connections shown. DO NOT use a "null modem" RS-232 cable.
