NOTE:- If more than one MultiScan is connected to the same 24v dc power sup-
ply, all terminals numbered 2 must be connected to the same side of the 24v dc
(ground) and all terminals numbered 3 must be connected to the other side of the
24v dc (positive).
The power supply that is used must be used for the MultiScan only (not connect-
ed to any other units) and the cable must not run near or with any control cables.
The power supply cables must be kept away from any control cables that are
connected to the relay control outputs, also sensor and transducer cables must be
kept away from the control cables.
NOTE:-Terminal 1 and 2 are connected together on the circuit board.
NOTE:- The power supply for the unit should be left on at all times to conserve
