Only recent 9 groups of the alarming record can be stored in memory of

A

i

205-P2 or -P3. The format of the record is,

When the alarming parameter resume normal (no longer over the limit), it is

also recorded. User can get the total period of over limit time.

Note: when the alarming parameter resume to normal, the highest bit of Var

bit15 is set to be 1.

Energy pulse output:

The two digital outputs (DO) can be select as energy

pulse output. Any two of the 8 energy and reactive energy can be assigned to be
as the pulse output. The pulse width and pulse ratio can be set, while pulse width
means how long the duration of the pulse is and pulse ratio means how much
energy that one pulse is represented. When the energy accumulates to the setting
limit, there will be a pulse output from the assigned DO port.

Pulse output assignment register: any integer from 0 to 8. The digit 0 means

no assignment, while 1 to 8 corresponding to Ep_imp, Ep_exp, Eq_imp, Eq_exp,
Ep_total, Ep_net, Eq_total and Eq_net respectively.
