3 8315 L&J Tankway Interface Module

3.1 Features

Supports up to 50 tanks
Communicates using L&J Tankway protocol
Interfaces to L&J Tankway compatible Tank Gauge transmitters
ANSI/IEEE surge protection
The Model 8215 interface with tank gauge transmitters uses Whessoe-Varec’s Mark/
Space protocol to communicate. There are a number of transmitters that are Mark/Space
compatible, including:
L&J MCG 1000
L&J MCG 1500
L&J MCG 2000
Note! The 8315 TankGate uses the 8215 communications module.
The Model 8315 requires an external +48VDC power supply. It is also possible to use the
+48VDC power supply of the TankGate to power the tank gauge transmitters, if there are
fewer than 15 devices. The following figure illustrates how the Model 8315 appears when
installed on the TankGate.
