57-657 SIL Certified Safety Manual for ECLIPSE Model 706
Step
Action
1
Bypass the PLC or take other action to avoid a false trip.
2
Inspect the unit in detail outside and inside for physical damage or evidence of environmental or
process leaks
a.) Inspect the exterior of the Unit housing. If there is any evidence of physical damage that may
impact the integrity of the housing and the environmental protection, the unit should be repaired
or replaced.
b.) Inspect the interior of the unit. Any evidence of moisture, from process or environment, is an
indication of housing damage, and the unit should be repaired or replaced.
3
Use the unit’s DIAGNOSTICS menu to observe Present Status, and review EVENT HISTORY in the
Event Log. Up to 10 events are stored. The events will be date and time stamped if the internal clock is
set and running. It is suggested that the internal clock be set at the time of commissioning of the unit.
If the clock is set at the time of the proof test, event times are calculated.
a.) Choose the menu DIAGNOSTICS / Present Status.
i.) Present Status should indicate OK.
b.) Choose the menu DIAGNOSTICS / EVENT HISTORY/ Event Log
i.) Any FAULT or WARNING messages must be investigated and understood.
ii.) Corrective actions should be taken for FAULT messages.

Proof Testing
7.1.1 Introduction
Following is the procedure utilized to detect Dangerous
Undetected (DU) failures.
7.1.2 Interval
To maintain the appropriate Safety Integrity Level of a
Safety Instrumented System, it is imperative that the entire
system be tested at regular time intervals (shown as TI in the
appropriate standards). The suitable SIL for the Model 706
transmitter is based on the assumption that the end user
will carry out this test and inspection at least once per year.
NOTE: It is the responsibility of the owner/operator to select the type
of inspection and the time period for these tests.
7.1.3 Recording Results
Results of the Proof Test should be recorded for future
reference.
7.1.4 Suggested Proof Test
The suggested proof test below, in combination with the
built-in automatic diagnostics, will detect 98% of possible
DU failures in Model 706-512x-xxx.
