default PSL is set up such that Function key 2 initiates a trip and Function key 3 initiates a close. For this to work
you have to set the CB control by cell to option 5 Opto+Local, or option 7 Opto+Local+Remote in the CB
CONTROL column.
As shown below, function keys 2 and 3 have already been assigned to CB control in the default PSL.

The programmable function key LEDs have been mapped such that they will indicate yellow whilst the keys are
activated.
Note:
Not all models provide function keys.

CB CONTROL USING THE OPTO-INPUTS

Certain applications may require the use of push buttons or other external signals to control the various CB control
operations. It is possible to connect such push buttons and signals to opto-inputs and map these to the relevant
DDB signals.
For this to work, you have to set the CB control by cell to option 4 opto, option 5 Opto+Local, option 6 Opto
+Remote, or option 7 Opto+Local+Remote in the CB CONTROL column.
7.5

REMOTE CB CONTROL

Remote CB control can be achieved by setting the CB Trip/Close cell in the SYSTEM DATA column to trip or close by
using a command over a communication link.
For this to work, you have to set the CB control by cell to option 2 Remote, option 3 Local+Remote, option 6
Opto+remote, or option 7 Opto+Local+Remote in the CB CONTROL column.
We recommend that you allocate separate relay output contacts for remote CB control and protection tripping.
This allows you to select the control outputs using a simple local/remote selector switch as shown below. Where
this feature is not required the same output contact(s) can be used for both protection and remote tripping.
