48-651 SIL Certified Safety Manual for E3 Modulevel
®
5.0 Supplementary Documentation
The E3 MODULEVEL Installation and Operating Manual
(Bulletin 48-635) must be available for installation of the
measuring system.
The following Electronic Device Description File is required
if HART is used:
Manufacturer Code 0x56
Model E3 MODULEVEL Device ID OxE3, device revision 2
DD revision 1
For device installations in a classified area, the relevant
safety instructions and electrical codes must be followed.
6.0 General Instructions
6.1 Systematic Limitations
The following instructions must be observed to avoid
systematic failures:
6.1.1 Application
The E3 MODULEVEL transmitter should be located for easy
access for service, configuration, and monitoring. There should
be sufficient headroom to allow installation and removal of the
transmitter head, and, in cases of tank top configuration, the
displacer. Special precautions should be made to prevent expo-
sure to corrosive atmosphere, excessive vibration, shock, or
physical damage. The E3 MODULEVEL should only be used
for applications in which buildup of solid materials on the
spring or in the enclosing tube is not an issue.
Caution: Operation of all buoyancy type level devices should be
done in such a way as to minimize the action of dynamic
forces on the float or displacer sensing element. Good
practice for reducing the likelihood of damage to the con-
trol is to equalize pressure across the device very slowly.
6.1.2 Environmental
Refer to the E3 MODULEVEL Installation and Operating
Manual (Bulletin 48-635) for Environmental limitations.
6.1.2.1 Operating
The operating temperature range is -40 to +175 °F (-40 to
+80 °C).
6.1.2.2 Storage
The device should be stored in its original shipping box
and not be subjected to temperatures outside the storage
temperature range of -50 to +185 °F (-46 to +85 °C).
