Assumptions for safety
Allocated
SSA 1
The user SIF will detect and properly handle annunciation of detected fault conditions
signaled by the alarm level output according to the specific requirements of the SIF.
End user’s responsibility
SSA 2
Proper operation of the ECLIPSE Enhanced Model 705 3x is dependent on having
11 VDC or greater across the transmitter terminals and at least 22 mA available in
the loop during normal operation.
End user’s responsibility
SSA 3
A user SIF integrating the ECLIPSE Enhanced Model 705 3x current loop output will
detect faulted field wiring and other faults resulting in a current loop value signal
outside of the specified range and take proper actions to maintain safety integrity
according to the specific requirements of the SIF.
End user’s responsibility
SSA 4
Optional Local User Interface will not be relied upon by the end user SIF during
normal operation and will be considered non-interfering to the safety function.
End user’s responsibility
SSA 5
HART communications will not be relied upon by the end user for the SIF normal
operation and will be considered non-interfering to the safety function.
End user’s responsibility
SSA 6
The impact of end user configured damping values is not included in the pub-
lished safety response time. (The end user must consider this as part of overall
time response of the SIF)
End user’s responsibility
SSA 7
The end user will independently verify all changes to end user configured
parameters and validate the safety functionality prior to reliance on the product
for safety protection.
End user’s responsibility
SSA 8
The end user will enable the User Password to lock out any end user modifiable con-
figuration parameters available via the Local User Interface during normal operation.
End user’s responsibility
SSA 9
Assumptions no longer required.
N/A
SSA 10
The end user will have proper procedures in place to ensure safe operation over
the product life cycle.
End user’s responsibility
SSA 11
The end user will ensure the device is properly installed per the product literature.
The proper probe will be used for the application with the transmitter properly
connected to the probe.
End user’s responsibility
SSA 12
The end user must not select HOLD for the level alarm output.
End user’s responsibility
SSA 13
The Loop Current mode must be enabled.
End user’s responsibility

SSA, System Safety Assumptions
The System Safety Assumptions provide a list of safety rele-
vant assumptions made on the usage of the product over the
safety life cycle of a user Safety Integrity Function, SIF.
MAGNETROL cannot directly control the user life cycle of
a SIF using this product but needs to have assumptions on
how the product will be used. It is important that users
have full knowledge of these assumptions to ensure they are
met when using the product as part of a SIF. This is to
ensure the product is used in a manner consistent with the
safety design.
This section only lists product specific assumptions and is
not intended to specify measures required of the end user
that are standard requirements for safety applications.
