Ease of Use & Operations
A Master HMI panel can be useful to paralleling
switchgear systems for user access and monitoring.
The key control and monitoring functions in these
systems include metering, annunciation, controlling
breakers and engine generators in automatic operations,
as well as manual.
This monitoring and control should be carefully considered
when selecting which type of
HMI is best suited for the
operator and his facility. The greatest reliability in monitoring
and control functions is realized with hardwired analog
meters, switches and annunciation indicators, with
very limited
HMI access needs by the operator.
In some cases, critical facilities may be suitable for
additional system monitoring, trouble-shooting and
remote access ability. Operators in this case will require
a more advanced Master
HMI in addition to the system
hardwired meters, switches and annunciation. The
Energy Commander
ACS “Advanced Control System”
is recommended for these cases.
The Energy
Commander
Operator Interface
Panel (
OIP ) is ideal
for simpler systems.
Since status of the
system can be viewed
in front of the line-up,
including all source metering, alarm, shutdown and
status annunciation, the operator is not required to
utilize the
OIP to cycle through any screens for the
system control and monitoring. The user is only required
to use the touch panel for system testing purposes,
non-critical settings and timing adjustments, and limited
manual control redundant to the hardwired switches.
System Bene
fits
Standard Operator Interface Panel ( OIP )
> Intuitive interface makes operation simple. Little or
no learning curve is required to operate the system.
> A main screen with navigation buttons and
non-system critical button/switches.
> System testing screen allowing the operator to
manually initiate automatic system testing operations.
> Generator interface settings latched into the PLC
control system upon entry.
> System load add/shed manual control redundant to
hardwired manual control switches in master control.
> Generator optimization settings latched into the
PLC control system upon entry.
