SIL Certified Safety Manual for Enhanced Model 705-51AX-XXX
5.8.2 Troubleshooting
Refer to Section 3.3 of the Enhanced ECLIPSE Model 705
I & O Manual 57-600 for troubleshooting the various
device status messages, which can be in the form of
Warnings and Faults.
To assist in finding Faults should they occur, complete the
Configuration Data Sheets included at the end of the
Installation and Operating Manual 57-650. Be sure to
include all device information, both in the working and
non-working modes.
• As there are no moving parts in this device, the only main-
tenance required is the proof test shown in Section 6.1.4.
• Firmware can only be upgraded by factory-trained personnel.
• Report all Faults to MAGNETROL technical support.

Proof Testing
6.1.1 Introduction
Following are the procedures utilized to detect Dangerous
Undetected (DU) failures.
6.1.2 Interval
To maintain the Safety Integrity Level of a Safety
Instrumented System, it is imperative that specified manual
proof testing be completed at the time intervals specified.
The user must select the type of inspection and the time
period for these tests.
The system check must be administered to prove that the pro-
tection functions meet the IEC specification, and as important,
result in the desired response of the safety system as a whole.
This system check can be guaranteed when the desired alarm
level height is obtained during the process operation.
If this is not practical, a suitable method of simulating the
level of the physical measurement must be used to allow the
level sensor to respond as if the fluid was filled above the
alarm/set point level.
If the operability of the sensor/transmitter can be deter-
mined by other means (that exclude all fault conditions that
may impair the normal functions of the device), the check
may also be completed by simulating the corresponding
output signal of the device.
6.1.3 Recording Results
“As Found” and “As Left” results of the Proof Test should be
recorded for future reference.
