Endress+Hauser SOP600 Manual

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.

Function and system design
Function The Endress+Hauser Liquiphant (point level switch) transmits the current level (point level exceeded
or not) to the Endress+Hauser Nivotester. If the High-High level is exceeded, the Nivotester opens
the fault-signaling contact which is connected to the safety PLC. The safety PLC detects a level alarm
and switches on the alarm siren and alarm strobe (field signaling MOPS) and/or opens the contact of
the tank-specific safety relay (AOPS). In addition, an alarm message appears on the touch panel and
text display unit, and the alarm is also signaled by the stack lights. If the High level is exceeded, this
only causes a warning message to appear on the touch panel and text display unit, and the stack
lights signal. A safety shutdown is not triggered, however. With the automated proof-testing
feature, the system offers users a simple, time-saving function that guides users through the proof
test on the touch panel. This proof test must be performed periodically (at least once per year) to
guarantee the functional integrity of the safety function. The actuator that is connected to the tank-
specific safety relays is not included in the scope of delivery. These are plant-specific and the
responsibility of the plant owner/operator.
There are two kinds of Overfill Prevention System:
•MOPS: The operator stops the supply of media to the tank by closing the corresponding valve or by
switching off the pump. This involves manual intervention in either case. The system alerts the
operator via the alarms on the display and via the signaling equipment installed in the field (siren
and strobe). In the event of a power failure, the integrated UPS ensures that the system remains
fully functional for up to 30 minutes.
•AOPS: The system prevents imminent tank overfill by automatically opening the fault-signaling
contacts, which in turn causes the connected actuator (valve/pump) to close/stop. No manual
intervention is required.

System design The Overfill Prevention System consists of:
• Cabinet for Overfill Prevention System
– Power unit (optional: redundant power unit, UPS and battery)
– SIL2 or SIL3 Nivotester (transmitter for Liquiphant)
– SIL3 PLC including input/output modules
– SIL3 safety relay
– Cabinet signaling (stack lights)
– 10" touch panel
– 2" text display unit (optional)
• Field signaling (siren and strobe) optionally for AOPS
• Point level switch (Liquiphant not included in system scope of delivery)
• SIL2 or SIL3 type certificate
– The SIL2/SIL3 type certificate considers the point level switches (Liquiphant), including the
Nivotester, remote I/Os, safety PLC, safety relay (AOPS) or field signaling (MOPS)
– The AOPS does not take the customer's actuator (valve/pump) into consideration
– A project-specific calculation for the corresponding SIL circuit (including actuators) can be
ordered as an option, or can be performed independently by the customer
Manual Overfill Prevention System (MOPS)
If overfilling is imminent, the system automatically activates signaling in the control room and
safety-oriented signaling in the field. The operating staff must then manually close or switch off the
actuator (valve/pump).
