3.6 Dipswitch Settings

The EAFR-110 functionality, such as tripping logic, is config-
ured using the dipswitch settings. The relay contains two
switch groups SW1 and SW2 (see Figure 5). The dipswitch-
es are located at the back of the relay for easy access.

Different trip configurations can be easily programmed by
selecting the appropriate dipswitch settings. The most
convenient way to set the EAFR-110 single relay or more
complex arc protection system is to use the Standard Arc
Configurations (SACs). For different SAC applications, see
the "Standard Arc Configurations" manual (MN026009EN).
Tripping may be selected based on arc light only or current
thresholds. Other tripping criteria, such as under-voltage or
similar, may be applied instead of over-current as well using
binary inputs. The circuit breaker failure protection (CBFP)
configuration may also be enabled using the dipswitches.
See Table 2: EAFR-110 Dipswitch SW1 Setting and Table 3:
EAFR-110 Dipswitch SW2 Setting for details of settings.
