Installation
This section discusses the installation and wiring of the hardware required to enable the TLS console to perform
pressure management of the site’s gasoline vapor processor equipment:
• Vapor Pressure Sensor
• Smart Sensor Interface Module
• NVMEM203 board
• Mod Bus Module
All field wiring, its type, its length, etc., used for TLS console sensors must conform to the requirements outlined in
the Veeder-Root TLS-3XX Site Prep manual (P/N 576013-879).
Vapor Pressure Sensor
Install one Vapor Pressure Sensor in the vapor return piping of the gasoline dispenser closest to the tanks
following the instructions in the Vapor Pressure Sensor Installation guide (P/N 577013-797).
Installing TLS Console Modules - General Notes
TLS consoles have three bays in which interface modules can be installed; Comm bay, Power bay and Intrinsically-
Safe bay (ref. Figure 1). Probe Interface modules and Smart Sensor modules are installed in the Intrinsically-Safe
bay and the Mod Bus module is installed in the Comm bay.
In all cases, the position of the modules, their respective connectors and the devices wired to the
connectors must be recorded to prevent improper replacement during installation or service. A circuit
directory for Power and I.S. bay Interface Modules is adhered to the back of the right-hand door for
this purpose.
Switch off power to the TLS console before you install modules and connect sensor wiring.
