A. Balance Box 21912, Installation for Analog Indicators
1. Introduction: Balance box 21912 is intended to be installed at the platform, one box
per section.
2. Description: Each Stainless Steel balance box has four (4) terminal blocks to
connect two (2) load cells and two (2) cables for connection to the analog
instrument. Load cells and sections are adjusted by means of adjusting
potentiometers.
3. Installation:
a. Boxes: The box has tabs for bolting to mounting brackets on the side of the
modules.
Attach the ground wire lug to one of the mounting bolt studs.
Tighten securely to provide a good electrical ground.
b. Wiring: Cable used in all wiring must be a minimum of 18 AWG.
Use cable 17204 or equivalent. The balance boxes are interconnected from
TB4 to TB3 beginning at the end section where the interface cable conduit
enters the scale. An alternate method if the conduit enters the scale in the
middle is to use 14478 Instrument SVP. This will allow separate connections to
go in each direction toward the ends of the scale. See Bulletin 50513 for the
wiring diagrams.
