Friendly Credit mode
Friendly hours can be switched on or off through a PC software or a remote command. When
friendly hours are on, in the preset friendly hours, the relay will not disconnect because of low credit
or negative number debt. Users can use power with a negative number credit until the friendly
hours come to the end. Details please see "Low credit disconnection during friendly hours" page
21.
Friendly hours are only allowed once after each charge. If the friendly hour is off, users have to
charge again to activate it.
Friendly hours are configurable (through PC software):
a) Night Time: for example 20:00~8:00, means 20:00 to 8:00 of the next morning
b) Weekends: At most two days
c) Holidays (13 different days)
d) Festivals (2 different days)
Correction Card
When the users are charging with a token number not belonging to them the utility can at a later
stage deduct this credit by means of a correction card. The utility can also use a correction card to
clear the open terminal cover tampering event and then detect repeated tamper events again.
After using a correction card, another correction card can be used after 5 minutes. If a used correc-
tion card is applied to the meter the display will show "USED"
Preset credit
After the meter comes out of the factory, utility can put preset credit into the meter to allow users
to use before they open their account through set card or PC software. After the users opened their
account and charging, the meter will deduct the preset credit automatically. For example: the pre-
set credit= 15, so the remaining credit= 15, the user consumed credit= 5, and after that the user
goes to open account and charging 10, after charging, the meter will deduct the preset credit, so
the remaining credit=5
Preset credit is only allowed to set once; it is not allowed to set after charging.
