Product Operation

Normally Closed switches such as a Tank Hi Level, or a separator high pressure etc., are connected to the input channels on the I.S. controller.

In the event that any one of these devices trips, the signal is open, or “lost”.

The I.S. Controller will see this signal loss, and the status light for that specific alarm will change from green to red.

At this time the I.S. Controller signals the I.S. solenoid, releasing the pneumatic pressure to the ESD valve, and shuts the well in.

** ( ELECTRIC ESD SIGNAL OPTION AVAILABLE WITH INTRINSICALLY SAFE BARRIER / RELAY ) ISSR-2
The status light for the valve changes from green to red.
Once the Alarm has been cleared,( the tank level has been lowered), simply press the “Reset” button to return the ESD valve to open.
