23. AUDIBLE ALARM

It is possible to configure an Audible Alarm to warn customers of events such as Low Credit Warning, Emergency Credit
Available and Load Limit. At present this is not implemented and is not a SMETS2 Requirement

24. AUXILIARY SWITCHES

24.1. Load Control Switch / HAN Auxiliary load control switch

The Meter Firmware can support up to five Auxiliary Load Control Switches (ALCS) or HAN Auxiliary Load Control Load
Switches (HCALCS). A single On-board Auxiliary Relay can be supplied as an option. This relay is rated at 230V, 2A. The
internal Auxiliary Load Control Switch will always be defined as Switch 1, it is not possible to reconfigure this from DCC. Any
calendar or commands intended for the internal switch need to be configured for and sent to Switch 1.
The display will show / allow the following information for each of the ALCS or HCALCS:
•
The status of the Optional On-board ALCS is shown by a dedicated icon on the display.
•
Status of each of the HCALCS is shown via the Chevrons:
- Chevron On = HCALCS On,
- Chevron Flashing = HCALCS Off,
- Chevron Off = Not Programmed
•
Status of each HCALCS is available via a menu display item
•
Option to exercise / test each of the ALCS / HCALCS:
- This will change the state of the switch for a 5 minute period
- The status of the test (available or in progress)
An event will be raised in the Event Log every time an ALCS / HCALCS is tested.
The current status for all the ALCS / HCALCS will be stored by the meter.
If the Main Meter Contactor is open the ALCS or HCALCS cannot be closed. If the power is restored to the meter and a
command should have been in operation, then this operation runs for the remaining period.
If there is a command received this takes precedence over the ALCS Switching Calendar.
