This Video Tutorial will show you how to change the Alarm State Action from Normally Open and Closed in Alarm to Normally Closed and Open in Alarm on a Eurotherm 2200 Series Controller.
The controller is setup as Alarm # 1 is a Full Scale High (FSH) and it is assigned to the AA Relay.
We are going to change the AA Relay Sense of Output from Normal (NOR) to Inverted (INV).
First we begin by putting the controller into the Configuration level.
Please note when putting the controller into the configuration level all outputs are shut off from the process. Before doing this, make sure it is safe to do so.
We will be using the four buttons across the bottom of the controller.
The left most button is called the PAGE Button.
The next button to the right is the SCROLL Button.
The next button to the right is the DOWN Button.
The final button to the right is the UP Button.
  • First we begin by pressing the Page Button repeatedly until you see the ACCS List.
  • Press the Scroll Key Once and you will see Code Pass, with the UP Button change the value Pass to 1.
  • Now press the Scroll Key Once and you will see GOTO OPER.
  • With the Up or Down Buttons change the value OPER to CONF.
  • Now press the Scroll Key once and you will see Code 0, with the UP Button change the value 0 to 2.
  • Now press the Page Button and the display will change to INST CONF.
  • Now press the Page Button repeatedly until the display reads AA Conf.
  • Now press the Scroll button repeatedly until the display reads SENS NOR
  • Now press the Up Button to change the displayed value from NOR to INV
  • Now press the Page Button repeatedly until the display reads Exit NO.
  • Press the Up Button to change the value NO to YES.
At this time the controller will reboot.
