Conversion transmitter Promag 50/53 W, P, H to Promag 55 remote version
2 Endress + Hauser
Safety instructions
• Use genuine parts from Endress+Hauser only.
• In the case of Ex-certified measuring devices: Only open in
a de-energized state (once a delay of 10 minutes has elapsed
after switching off the power supply) or in environments which
do not have a potentially explosive atmosphere.
• The measuring device is energized. Danger: Risk of electric
shock! Open the measuring device in a de-energized state only.
• Before removing the device: set the process in a safe condition
and purge the pipe of dangerous materials.
• Hot surfaces! Risk of injury! Before commencing work, allow the
system and measuring device to cool down to a touchable
temperature.
• Comply with national regulations governing mounting, electrical
installation, commissioning, maintenance and conversion
procedures.
• Requirements with regard to specialized technical staff for the
mounting, electrical installation, commissioning, maintenance
and conversion of the measuring devices:
–trained in instrument safety
–familiar with the individual operation conditions of the devices
–for Ex-certified measuring devices: also trained in explosion
protection
• Follow the Operating Instructions for the device.
• Risk of damaging electronic components! Ensure you have
a working environment protected from electrostatic discharge.
• After removing the electronics cover, there is a risk of electric shock
as shock protection is removed!
Switch off the measuring device before removing internal covers.
• In the case of measuring devices in safety-related applications in
accordance with IEC 61508 or IEC 61511: After
conversion
recommission in accordance with Operating Instructions.
Document the
conversion
procedure.
• Only open housing for a brief period. Avoid the penetration of
foreign bodies, moisture or contaminants.
• Printed circuit boards for devices in categories II1G, II1D, II 2G,
II 2D, Zone 1 and Class I, Div. 1, Gp. A, B, C, D have a recess or
printed board code. Unauthorized breaking of this coding is not
permitted, as explosion protection will then be invalidated.
• Caution! When replacing amplifier boards, I/O boards or
submodules, ensure compatibility with existing software. The
process for reading out the software revision number is
described in the Operating Instructions (device functions). If the
software of the board is not compatible, it should be updated
using an operating software package (e.g. Field Care). In the
event of functional changes, notify the plant owner/operator.
• Replace defective seal/gaskets with genuine parts from
Endress+Hauser only.
• If threads are damaged or defective, the measuring device must
be repaired.
• Threads (e.g. of the cover for the electronics and connection
compartments) must be lubricated. Use an acid-free, non-hardening
grease if an abrasion resistant dry lubricant is non-existent.
• If spacing is reduced or the dielectric strength of the measuring
device cannot be guaranteed during conversion work, perform
a test on completion of the work (e.g. high-voltage test in
accordance with the manufacturer's instructions).
• Service connector:
–do not connect in potentially explosive atmospheres.
–only connect to Endress+Hauser service devices.
• Observe the instructions for transporting and returning the
device outlined in the Operating Instructions.
• If you have any questions, contact your E+H service
organization.
