Logic Conditions
For the purpose of positive shutdowns, logic conditions use a status based approach typically
combined with OR logic. This approach allows the console to be configured with multiple
devices and multiple alarms under one condition and ties these status conditions to one or more
programmed outputs. In the case of positive shutdown, the output will be programmed for a
submersible turbine or multiple submersible turbines using either TPI or Relay Output(s)/Relay
Module(s).
• Condition Inputs are programmed to include any combination of sensor alarms or other
alarms that are to be include in the disabling of a submersible turbine. For example, the
owner operator may want the submersible turbines to be disabled for 3-wire sensor
(unleaded sump) “product alarm” or at a tank level alarm (unleaded tank) of Low or low
low. All required alarms in this scenario can be included under one condition to disable a
specific turbine (unleaded STP).
• An additional condition can be created to disable all submersible turbines for example, in
the event of a dispenser sump sensor alarm.
• NOTE: Creating multiple conditions with the same output can lead to conflicts and all
required conditions should be mapped out prior to programming.
• 4-20mA- LS500 line leak transducer (requirement for Electronic Line Leak Detection
(ELLD))
• Provide ability to energize turbine for testing and disable turbine in the event of
ELLD alarm (positive shutdown)
