Application
The Overfill Prevention System is type-certified up to SIL3 according to IEC 61511
and meets the requirements of API2350 and WHG (German Water Resources Act).
Two versions of the system are available (automatic and manual) and are designed
for 1 to 16 tanks. If the High-High level is exceeded, a safety relay is disabled or field
signaling is enabled (SIL function). Optionally, the High level can also be monitored
as a warning (for information purposes only, no SIL function). The Overfill
Prevention System features detailed warnings and alarms on the touch panel and on
the optional 2" text display unit, system status indication via stack lights and safety-
oriented alarm signaling in the field (optionally AOPS). The text display unit can be
mounted in the cabinet door or in an external housing and helps users to read the
current system status from afar. The system has an automated proof test cycle, which
must be performed periodically to maintain functional safety. A corresponding report
can be printed out on a printer (optional). The system offers an UPS (optionally
AOPS) for 30-minute operation in the event of a power failure.
