2 Detailed information
Using the COC4 – A01D1 overcurrent protection relay as a typical example, the following explains how to operate
this type of relay. The item numbers and details depend on model. See the section of “Operational procedure” of
the instruction manual of the model.
In this section, the lamp status of the indicator LEDs are shown according to the following rule using symbols:

This item indicates the settings with the item No. “500” range and option with “800” to “900” range.
<< Example >> To indicate the following settings and options:
(1) Item No. “511” – “Phase fault time-delayed element operating current” : 1.0 A
(2) Item No. “542” – “Earth fault instantaneous element operating time” : INST
(3) Item No. “800” (“Contact X0arrangement”) : Contact arrangement data setting 0100.
(4) Item No. “902” (“CT Zero-phase primary current”) : 5.0 A

【B】 Setting mode (Item No. : “500” range)
(1) If the relay is in one of the following condition, the settings including operating current and time can be free changed by
following the procedure B - 1 .
-The relay is without RS232C communication I/F
-RS232C communication I/F is located but the relay password function is in the “disable” status.
(refer to D - 9 )
Note that two or more items of setting can be changed at a time as long as all of them belong to the setting mode (the “500” range),
but can not be changed if at least one of them belongs the forced operation (the “700” range) or option mode (the “800” to “900”
range).
B - 1 Establishing settings
<< Example >> To change the operating current and time of the earth fault time-delayed element to the following
values:
(1) Operating current ..................... 0.15 A →0.25 A
(2) Operating time multiplier........... 0.25 →10
