Parameter Definition

regardless of whichever SP is active.

NOTE 4. Loop Break monitors the control loop to determine if it is working. When enabled, the control output is checked against the minimum and maximum output limit settings. When the output reaches one of these limits, a timer begins. If the timer expires and the output has not caused the PV to move by a pre- determined amount, then the alarm activates, thus signalling that the loop is broken. The loop break timer value must be configured by the operator as the AxSx VAL entry. This value is in seconds with a range of 0 to 3600 seconds. A setting of 0 is equivalent to an instantaneous loop break when the output reaches one of its limit values.

The amount of PV Movement required is determined by the “UNITS” setting in the Display Setup Group. For the Degrees F configuration, the PV must move by 3° in the desired direction in the time allowed. For the Degrees C configuration, the PV must move by 2° in the desired direction in the time allowed. For the “NONE” selection, the PV must move 1% of the PV range in the time allowed.

Loop Break alarms do not have a HIGH/LOW State configuration, they are always assumed to be a HIGH state alarm.

NOTE 5. Thermocouple Warning means that the instrument has detected that the Thermocouple Input is starting to fail. Not valid for other input types.

NOTE 6. Thermocouple Failing means that the instrument has detected that the Thermocouple Input is in imminent danger of failing. Not valid for other input types.

NOTE 7: For the Digital Input selections, DIG INP1 can be either enabled or disabled in the Options Group (See Sub-Section3.11), but DIG INP2 must be enabled in the Options Group for the alarm to function properly.
