LS-500 Setup (Console Programming)

The following instructions are a guide to programming the LS-500 only. The administrator password will be necessary to 

save the programming changes. For instruction on FMS programming, or how to obtain the Administrator access level, 

please refer to the T5 Series FMS Programming Guide (p/n 000-2142) or the TS-550evo FMS Programming Guide (p/n 

000-2173).
Access the T5 Series FMS console (via the LCD touch screen or by the web) and navigate to the Setup Menu, Go to each 

of the following parameters, shown in the next tables, and set them accordingly per the site. You will be prompted to enter 

the Administrator password when it is required. 
Note:  Site setups vary depending on the products used and other equipment installed. Setup information in the sections 

of this chapter depicts a typical site and are meant as examples only.

AC Input Module

One of the functions of the AC input module is to accept incoming dispenser hook signals. The hook signal tells the 

console which product the dispenser is requesting, then turns the appropriate Submersible Turbine Pump (STP) on using 

either a relay (from the relay board or from the power supply board) or the turbine pump interface (TPI). The LS500 is 

constantly monitoring the pressure on the line, and testing accordingly. To perform tests properly, the LS500 needs to 

know when the pumps are being used by other applications.

Parameter

Parameter value

Number of Gasoline Hooks 

per Dispenser

The number of product hook signal inputs to the console from each dispenser.

Channels

Select the number of inputs in use.

Name

Text box, name each channel to easily identify in the mapping.

Enabled

Select YES. This will allow the channel to be mapped to another module. Other modules 

need this signal to trigger events.

Active State

Select HIGH. A high signal level will activate the channel and a low signal will deactivate 

the channel. If set to low, then the channel is inverted and will only become active when 

a signal is absent and inactive when a signal is present.

Action

Select NONE
