20 Monitor (Absolute) block
20.1 Function
♦ The Monitor (Absolute) block is responsible for limit setpoint monitoring
with absolute limit values. In the User Menu the block name is
abbreviated to Monitor(Absolute). For the alert alarm, danger alarm and
other limit values there is a respective Monitor (Absolute) block.
♦ The Monitor (Absolute) block is an optional signal path component. As a
configuration interface it contains a group of parameters which are
necessary for the settings.
♦ The Monitor (Absolute) block processes the measurements from
preceding measurement blocks (e.g. RMS measurement, BCU
measurement, etc.). The incoming measured value is compared with an
absolute limit setpoint. With a high violation (or also a low violation) of
the limit setpoint and after an adjustable time delay a corresponding
event (Alert alarm, Danger alarm, or a message) is signalled.
♦ Often the Monitor (Absolute) block directly controls a relay output. If this
is the case an LED on the relay module is used to signal the monitoring
condition (see the chapter on the relay block in section C and the
chapter on signalling in section A).
♦ If required the Monitor (Absolute) block can be operated with an
automatic Trip-multiplier function. This function is however independent
of the respective instrument configuration.
20.2 Parameters and their setting ranges
20.2.1 Parameter list
♦ <Limit type>
This parameter determines whether a high or a low limit setpoint is
being handled. When it is a high limit setpoint, an event (e.g. an alert
alarm) is initiated when the measured value is higher than this limit
setpoint. Correspondingly when a low limit is violated by a measured
value that is lower. The setting can be changed at the instrument.
Limit type High limit or low limit
Works pre-setting High limit for high alert alarm and
high danger alarm; or low limit for low
alert alarm and low danger alarm
