Custom Alarm/Alert Messages with Troubleshooting Guides (cont)
F. NORMAL RUN
G. NORMAL RUN WITH OVERRIDES
*[LIMIT] is shown on the CVC as the temperature, pressure, voltage, etc., set point predefined or selected by the operator as an override, alert, or
alarm condition. [VALUE] is the actual pressure, temperature, voltage, etc., at which the control has recorded at the time of the fault condition.
