Customer Interface Unit - Specific Functions
12.1 General
The Customer Interface Unit (CIU) is effectively a r
emote extension of the meter‟s Human Machine
Interface. It does, however, implement some local functions independently:
12.2 Audible Low-Credit Alarm
This function is provided to give consumers the option of having a timeous audible warning that credit
is low and disconnection of the electricity supply could occur soon.
If needed (during normal operation of the customer interface unit), the above default settings can be
changed by pressing and holding the „0‟ key on the keypad for 5 seconds. At the end of this period
the buzzer beeps once (alarm disabled) or twice (alarm enabled). The mode can be toggled any
number of times.
If the default setting of the alarm is changed via the keypad, it will revert to the
default status every time power is removed from the customer interface unit.
12.3 Other Audible Tones
The customer interface unit generates a variety of tones in response to token entries e.g. there are
two distinctly different tones to indicate Transfer Number Accept or Transfer Number Reject
sequences.
