6.2.25 Load Shed
The load shed function is used primarily with automatic
trans-fer switch units. When a transfer switch unit is in
emergency mode, and there is a call to start – the LMR
controller will send a signal to an external circuit breaker
which will turn off electrical loads within a facility. At the
same time, a user programmable 0-15 second time delay is
initiated, which delays the controller from operating, thus
allowing the loads to be fully shed prior to the controller
turning on.
Messages indicating “Transfer Switch in Emergency” and
“Load Shed Closed”, are stored in memory for printing and
viewing. The load shed time delay will not be activated if
an emergency start is initiated.
7.0 Alarm/Status Messages
The LMR Fire Pump Controller is equipped with a dot
matrix thermal printer for troubleshooting and alarming
purposes. It also serves as a pressure chart recorder.
Each alarm/event is stamped with the date and time of the
occurrence. Note that all alarms, in addition to being printed,
can also be viewed via the LCD display or downloaded to a
computer via an RS232 link. A cable and special software is
required for downloading to a computer. If required, please
contact Cutler-Hammer. Refer to section 4.3.
A sample printout of the alarm messages is found below:
7.1
Printer / Recorder
Mounted inside the enclosure, the printer-recorder provides a
hard copy status report of all alarms, events, voltage, system
pressure, weekly test timer and programmed parameters of
the controller. Each alarm printout is stamped with the time
and date that can be used as a trouble-shooting tool to
determine start-up causes and exact times of all events.
NOTE:
Printer shipped with controller may differ than
shown above.
