Operation counter
4.2.4
The DPOS01 function has an operation-counter†; the user can utilize the operation-counter to
predict the lifespan of switchgear and other functions. The user can select a count mode using
a setting. Table 4.2-21 and Figure 4.2-32 show the modes, for which a user is required to change
a mode in response to a device signal. For instance for the DPOS01 function, a user can select
the mode using scheme switch [DPOS01-CNTS], which is set to C-On; counting-up is performed
when a switchgear signal gives rise to a change in state from "Off to On".
Mode Description
Counting-up is performed when a signal changes to closed (On). When the signal
C-On
is changed from "Off to On", the counter value is incremented.
Counting-up is performed when a signal changes to open (Off). When the signal
C-Off
is changed from "On to Off", the counter value is incremented.
Counting-up occurs when any state change occurs: that is, "Off to On" or "On to
C-OnOff
Off".
Stop the count function
NA
†Note: The operation-counter value is not cleared when power is removed from the IED.
The operation-counter is available in the DPOS01 to DPOS72 functions.
The user can change the value of the operation-counter from either the front panel or
remotely. For example, in the sub-menu for "Operation counter", the user can set a user-
preferred value for the operation-counter. See chapter
(→p. 989).

Note: With regard to signal "DPOS01_3PH_STATE", the sub-menu represents it as
"DPOS_Dev1-3Ph". Analogous to the signal "DPOS01_3PH_STATE",
"DPOS01_APH_STATE" is represented as "DPOS_Dev1-APh". Signals
"DPOS01_BPH_STATE" and "DPOS01_CPH_STATE" are displayed in a similar
manner.
