DigiTOL DLC Mode
A Model 2160 floor scale is used with a DigiTOL junction box for summing load cell
outputs. Only DigiTOL indicators work with a DigiTOL junction box. In the DLC mode, the
indicator serves as the host for the DigiTOL junction box, allowing you to use the
indicator’s keypad to adjust scale parameters. See Figure 3-7 and Table 3-2 for cable
connections.
WARNING
DO NOT USE THE DigiTOL JUNCTION BOX IN LOCATIONS
CLASSIFIED AS HAZARDOUS BY THE NATIONAL
ELECTRICAL CODE (NEC) ARTICLE 500.
