NOTE: In the diagrams shown below, the ID# corresponds to the Instance ID in the Automation Inputs and Outputs table. When the Priming Request bit is ON, the EFR will start priming as long as the System On bit is also ON. If the System On bit or the Priming Request bit is OFF, the EFR will stop priming. - Page 13 Available Internal Data When the Parking Request bit is ON, the EFR will start parking as long as the System On bit is also ON.

- Page 14 Available Internal Data When the Purge Request bit is ON, the EFR will start purging as long as the System On bit is also ON. If the System On bit or the Purge Request bit is OFF, the EFR will stop purging. The purge flow rate can be modified quickly through the data exchange.
- Page 15 Available Internal Data If the sequence is not in operator mode, a pulse on the Start Current Sequence/Step, Trigger Operator Mode bit will play the active sequence. Sending the Desired Active Sequence byte is optional. If the The Desired Active Sequence byte is not sent, the current active sequence stored in the EFR will be used.
- Page 16 Available Internal Data If there is a step in operator mode throughout the active sequence, the EFR will only dispense that step if the Start Current Sequence/Step, Trigger Operator Mode bit remains ON. Once the Start Current Sequence/Step, Trigger Operator Mode bit is OFF, the EFR will continue with the active sequence. Sending the Desired Active Sequence byte is optional.
- Page 17 Available Internal Data An ON pulse across the Stop Current Sequence bit will stop the active sequence. Sending the Desired Active Sequence byte is optional. If the The Desired Active Sequence byte is not sent, the current active sequence stored in the EFR will be used. 3A6338B...
- Page 18 Available Internal Data An ON pulse across the System Shutdown Request bit will stop the sequence and turn the System On bit OFF, making the system inactive. A toggle OFF followed by a toggle ON of the System Enabled Request bit will put the system back into the active state after the EFR has shut down.
