Date & Time
There are two types of Date & Time accessible from the OCR of the MCCB and which are used as timestamp of trips, alarms, and events, and which are
affected by the presence of supply or control power to the OCR.
OCR Time:
Non-resettable time which is the absolute operating time of the OCR seconds. OCR time increments whilst the OCR is in service and
is stored in the OCR non-volatile memory. OCR time does not increment if power is removed from the OCR.
User Time:
Resettable time which is configurable by the user locally via the P_SE OCR embedded display, or remotely via TPED or TPCM. This
time is displayed on the P_SE OCR embedded display. Unlike the OCR time, however, the User Time is stored in volatile memory,
and is cleared back to 1
st
January 2000, 00:00:00 if power is removed from the OCR.
On the embedded display of the MCCB, the date and time is represented in the format DD/MM/YYYY (or YYYY/MM/DD depending on settings) and HH:MM
(24H or AM/PM depending on settings).
Notice
: where accuracy of timestamps are critical (e.g. for alarm history and logging), it is recommended that
the OCR is supplied with an uninterruptable external power supply. This is such that disconnection of incoming
supply does not remove power from the OCR and reset the User Time and cease upkeep of OCR time.
