Description

Vibro-meter 200-505-013-011
Environmental restrictions are described in Appendix A of the hardware manual.
Configuring the system
NOTE: The procedures described should only be performed by competent and authorised
personnel following the plant specific guidelines in force at the installation site.
Define the levels
The choice of alarm levels must be made in consultation with the site manager. It is the end
user’s responsibility to ensure that the alarm levels are appropriate for the particular system
being protected.
The levels are defined using either the VM600 MPS1 software (supplied) or the VM600 MPS2
software (optional). Refer to the appropriate documentation for complete information.
NOTE: Refer to a VM600 MPSx configuration software for machinery protection systems
software manual for further information (see 1.5 Related documentation).
Define the alarm outputs
Any relay on the MPC4 or RLC16 cards can be configured to provide the safety function. As
previously noted in 2.1 VM600 in a safety-related system, for a safety relay corresponding to
an alarm, the alarms and relays must be configured depending on the role of the VM600 in
the safety loop.
• If a safety function is performed by a VM600-rack based system only, any safety relay
corresponding to an alarm must be configured as latching and normally energised
(de-energised to trip).
• If a safety function is performed by an external system using an alarm detected by a
VM600-rack based system as an input, the relay corresponding to this alarm may not be
configured as latching.
However, an analysis must be carried out at the safety-related system level to ensure
that no alarm can be missed or to identify all possible impacts and acceptability of
residual risks in case of a missed alarm.
• If a safety function uses a VM600-rack based system alarm that is configured as latching,
the use of an alarm delay time is not allowed. That is, the alarm delay time (Delay) for
the alarm must be configured as zero (0.0).
