5.2.2.2. Overrun Alarm
This function provides an overrun alarm to detect a leakage or a stuck valve. If the programmed overrun volume is reached after the batch end, the option relay (OUT2) is energized and the front panel led indicator placed below OUT2 icon turns on to indicate the valve is leaking or the valve is stuck open. Press ESC key to clear the alarm. The overrun alarm will re-trigger if the leakage persists.
