Introduction
Gasoline Pump and Line Requirements
Gasoline Pump and Line Requirements
All gasoline STPs (Pumps) have the following setup requirements via Setup> Pump and Lines. Each gasoline tank
must be assigned to a pump via Setup> Pump and Lines> Pumps. The created pump must then be assigned to a
line via Setup> Pump and Lines> Lines. These pump/line assignments are required to properly setup the ISD shut
down requirements.
ISD Shutdown Requirements
For ISD on the TLS-450PLUS, the gasoline lines must be able to be shutdown for required ISD Site/Hose alarms.
Dispenser relays may be used to shut down gasoline dispensers for Hose alarms.
The TLS 450 setup requires at least one Line to shutdown for required ISD alarms, otherwise the ‘Missing Relay’
warning will post. Ensure that all gasoline Lines/Hoses are configured to shutdown on required ISD Site/Hose
alarms. Hoses may also be shutdown using dispenser relays. ISD shutdown requirements is accomplished using
Automatic Events Setup. Refer to Table 3 for required ISD Shutdown alarms.
