Custom Alarm/Alert Messages with Troubleshooting Guides (cont)
D. PRE-START ALERTS: These alerts only delay start-up. When alert is corrected, the start-up will continue.
No reset is necessary.
*[LIMIT] is shown on the CVC as temperature, pressure, voltage, etc., predefined or selected by the operator as an override or an alert. [VALUE] is
the actual pressure, temperature, voltage, etc., at which the control tripped.
