5 Operation
5.1 Automatic operation
When in the closed state the
Fusesaver operates automatically
to clear faults on the line as per the
user-configured settings. Refer to
KFS-2034 manual for details on
Fusesaver configuration options.
5.2 Manual operation
The communications module is fitted
with two actuators. When operated by
pushing upwards, the Fusesaver opens or
closes. The actuators are color coded:
Color
Operation
Green
Opens the Fusesaver
Red
Closes the Fusesaver
Note that by special order these colors
can be reversed.
Operation of actuators
After pushing an actuator, there is a
time delay before the Fusesaver
operates. The delay is configurable from
0 to 60 seconds for an open and fixed at
60 seconds for a close.
When an actuator has first pushed the
LED on the communications module
flashes for several seconds at a fast rate
to let the user know that the operation
has been requested. Once the operation
is scheduled, the LED keeps blinking
confirming the trip or close instruction
is pending. If the action is rejected,
then the LED stops blinking. Reasons
for rejection might include that the
Fusesaver is already in the requested
state or because the external lever is
pulled down.
Once scheduled, the action can only
be cancelled by use of the external
lever on the Fusesaver subject to the
configuration setting. Cancellation only
applies to the Fusesaver whose lever
is pulled down.
When multiple Fusesavers are used
on a two or three phase line, they can
be configured so that pushing the
actuator on one communications
module operates all the Fusesavers on
the line as if the actuators have been
pushed on all three at the same time.
This is achieved by the communications
modules using their radios to
communicate with each other.
