5. Testing the alarm limits
• The controller should currently be in the manual mode. There are two ways to
generate an alarm with the training equipment we are using. The analog output of the
controller will have a loop-back connector wired to the analog input.
• If the current output is zero, the controller should already be in alarm.
• Press the Dot button once to acknowledge the flashing alarm. There should also be a
LOW alarm indicator across the screen.
• Press and hold the output increase pushbutton. As the output increases, the process
variable will also increase. When the process variable rises above the alarm limit, the
LOW alarm indicator will disappear.
• As the output continues to increase, the process variable will reach the high alarm
limit. The flashing alarm will return and the HIGH indicator will be displayed.
• Pressing the DOT pushbutton will acknowledge the flashing alarm. The HIGH
indication will remain until the process variable falls below the alarm point.
