Honeywell Enraf Operation Manual page 9

Part No.: 44200004 - Revision 2
The Honeywell Enraf Prover Series
Warning
For information on the dimensions of the flameproof joints, contact
Honeywell Enraf.
Warning – Risk of injury
Honeywell Enraf recommends mains power to be shut off, including
lockout-tagout at that mains switch to ensure safety during maintenance
and related work being performed on the inside of the drive end cover.
Warning – Risk of injury
Ensure that the motor drive end and downstream shaft covers are always
in place before operating the device, to guard against human injury.
Warning – Risk of injury
Pressurize system slowly to avoid a hydraulic shock which could result in
damage to prover, personnel, and/or piping systems.
Warning – Risk of injury
Ensure that the unit is fully depressurized and drained prior to disassembly
or service.
Commissioning
The commissioning of the instrument shall be conducted by qualified
engineers, trained by Honeywell Enraf and with knowledge of the
(local and national) requirements for electrical equipment in (potentially)
explosive atmospheres.
Operation
After commissioning the Honeywell Enraf SVP and its associated
SVP Controller can be used for its intended purpose. After connecting
to the SVP Controller the LAD can be used for its intended purpose. The
memory card can be removed and inserted also in hazardous areas but be
aware that the device is then no longer suitably protected against ingress
of water.
Maintenance and troubleshooting
In the unlikely event of malfunction, only a qualified service engineer, trained
by Honeywell Enraf and with knowledge of safety regulations for working in
(potentially) explosive atmospheres is allowed to repair the instrument.
