3.6 Dipswitch settings
The EAFR-110PLV functionality, such as tripping logic, is configured
using the dipswitch settings. The relay contains two switch groups
SW1 and SW2 (see Figure 4). The dipswitches are located at the
back of the relay for easy access.
Figure 4. EAFR-110PLV dipswitches SW2 and SW1.
Different trip configurations can be easily programmed by selecting
the appropriate dipswitch settings. The most convenient way to
set the EAFR-110PLV single relay or more complex arc protection
system is to use the Standard Arc Schemes for Arc Quenching
Switchgear. For different arc schemes applications, see the Standard
Arc Flash Relay Schematics for Arc Quenching Switchgear manual
(IB0191003EN).
Tripping may be selected based on arc light only or current thresh-
olds. 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-110PLV Dipswitch
SW1 Setting and Table 3: EAFR-110PLV Dipswitch SW2 Setting for
details of settings.

Latch or non-latch for HSO1 and HSO2.
HSO1 and HSO2 operates as latched. HSO1 and HSO2 operates as non-latched.

Fast / CBFP
Selection of trip relay T2 function.
Trip relay T2 will have 7 ms trip time. Trip relay T2 will work as CBFP relay. If any sensor
or light input (BI2) is activated for more than the
set CBFP time (100 or 150 ms), the CBFP function
activates the trip relay T2 and binary output BO1.
Note:
Master trip command (BI2, see dipswitch 4)
will not activate T2 when in CBFP mode
