3.4 Reset
All LED indications and latched trip relays are reset by
pressing the “SET” button for one second. Otherwise, the
latched trip relays will remain activated until auxiliary power
is disconnected. All LED indications will remain active until
reset is performed by the operator, even when auxiliary
power supply is disconnected (see Section 3.6: Non-volatile
Memory).
3.5 Dipswitch Settings
EAFR-101S functionality, such as tripping logic, is configured
using dipswitch settings. Different trip configurations can
be easily programmed by selecting the appropriate dip-
switch positions. This gives users the flexibility to change.
settings dependent on the application. Tripping may be
selected based on arc light only or arc light and current
thresholds. Current threshold or other tripping criteria may
be applied to binary input BI1 for blocking a trip caused by
natural light sources. Also, the CBFP configuration may
be enabled using the dipswitches (dipswitch number 4 is
enabling the CBFP function for corresponding configuration
selections). Dipswitches 1 through 4 are used as configu-
ration selection. The configuration number is according
to binary arithmetic. Switch 1 equals a count of 1, switch
2 equals a count of 2, switch 3 equals a count of 4, and
switch 4 equals a count of five.
Dipswitches are located at the back of the relay for easy
access (see Figure 4: EAFR-101S Dipswitch SW1 and Table
2: EAFR-101S Dipswitch Setting Selection for details of
settings).
