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.
