LED Operation
- This is a Normally Closed sensor designed for Leak Detection.
- Under normal operating conditions (power applied), when no leak is detected, the dry contacts will remain closed.
- Upon detection of a leak, the contacts will open.
- THE CONTACTS WILL REMAIN OPEN WHEN THE DEVICE IS UNPOWERED, HAS FAILED, REACHED END-OF-LIFE, OR IS OUT OF CALIBRATION.
- THE CONTACTS SHALL REMAIN CLOSED WHEN THE DEVICE IS POWERED AND NO LEAK IS DETECTED.
- ONCE THE LEAK DETECTION HAS RESET, THE CONTACTS SHALL REMAIN OPEN FOR A MINIMUM OF 5 MINUTES.
- IF THE LEAK DETECTION HAS CLEARED AND THE 5-MINUTE PERIOD HAS LAPSED, THE CONTACTS SHALL RETURN TO THE CLOSED STATE.
