3.4 INPUT WIRING
The Large Display has two signal inputs, A and B. These inputs are wired to
terminal block TBB located inside the unit on the right side.
Terminal 1: Input A
Terminal 3: Input B
Terminal 2: Input Common
All other models are non-programmable and provide Count with Direction
Mode only. Input A accepts the count signal, while Input B controls the count
direction (up/down).
Input B can also be used to adjust the LED display intensity by setting DIP
Switch 8 to the ON position (See Section 2.0, Setting the DIP Switches). For
programmable models, this only applies in Count with Direction mode.
Programmable models LD2006P0 and LD4006P0 provide a choice of eight
different Count Modes. The Count Mode selected determines the action of
Inputs A and B. Section 5.1, Input Setup Parameters, provides details on count
mode selection and input action.
CAUTION : User common is NOT isolated from input common. In order to preserve the safety of the meter application, the DC common must be suitably
isolated from hazardous live earth referenced voltage; or input common must be at protective earth ground potential. If not, hazardous voltage may
be present at the User Input and Input Common terminals. Appropriate considerations must then be given to the potential of the input common with
respect to earth ground.
