You have attempted to set the product Set Point and/or Deadband beyond the cal-
ibrated range of the product.
Verify the range of the One

and Deadband values to ensure
that they do not exceed the

:
For High Limit Alarm, when the pressure goes above Set Point the output closes. Both
the local and remote status indicators flash, signaling a tripped output. The switch resets once
the pressure has dropped below the set point value minus the deadband, and both the Output
Status LED and IAW output signals return to steady ON.
