its normal operating mode. The process will operate indefinitely in an alarm condition unless an operator notices
it, because the alarm will not activate since it never entered the normal range.
By setting the start delay, the alarm inhibit will be disabled once this time period is exceeded from the start-up
of the system. The allowable time setting is from 0
– 32,760 seconds. A value of zero (0) disables the alarm
start delay timer, so inhibit will be on indefinitely until the alarm input reaches normal operating range.
The
Alarm Message is the text notification that appears on the Alarm screen when the alarm activates. This
message can be edited (up to 25 characters maximum) so that the alarm message more accurately describes
what the alarm means.
9.3.2 Output Defeat
The alarms can be used to disable outputs of the MCT when in an alarm condition. To assign which outputs
are to be disabled when the alarm occurs, press the ‘Defeat’ button on the Alarm screen.
Select which outputs are to be turned off when the alarm is active by pressing the on/off button associated with
the desired output(s) and press the ‘Return’ button when finished.
9.4 Limits
The set point Limits screen allows for the adjustment of the minimum and maximum operating set points allowed
to be entered for the control loops. These limits can be used to prevent operators from entering a value that
exceeds the survivability limits of equipment or product being manufactured, reducing the risk of property
damage.
