Emergency Shutdown Procedures
The load bank provides two methods of quickly shutting down the load bank in an
emergency:
Emergency stop button.
The emergency stop button, located in the control room, is a
latching mushroom type push button. The load is removed and the fan will stop running,
but the control system remains powered. Twist to reset the switch after it has been used.
The Start button will not re-enable the control system until the switch has been reset.
The Fan and Controls Supply Isolator.
This is a two position switch which isolates the
power supply to the fan and controls when it is in the off position. It can be used to perform
an emergency stop, but it can also be padlocked in the off position and this means it can
be used to secure the load bank from unauthorised operation.

The Fan and Controls Supply Isolator
Warning! If the fan is
stopped when the load
elements are hot the
temperature with the
load bank will increase
considerably. The load
bank is designed to
withstand this without
damage, but the hot air
that builds up inside the
load bank could prove
to be a hazard. Please
ensure that the fan out-
let is kept clear when
the fan is restarted.
Load Bank Operation
Warning! Operating
the Fan and Controls
Supply Isolator or Stop
Button does not isolate
the Supply-on-Test
from the load bank
wiring. Some of circuits
within the load bank will
remain live.
