that the day selected is then, say, the third Sunday of the month - regardless of the month or
year.
Option 3:date allows the entry of a specific day 1-31 to select the day of the month, i.e., 1
being the first day of the month, etc.
The second of the two daylight saving menus has options of 1:hour and 2:minute. This
allows the setting of the time difference in hours (0-23) and minutes (0-59), which is the
amount of time to be added or subtracted when the daylight saving change occurs. These
values must be programmed for both daylight saving start and end.
6.4.4.10 Mains/Battery Options
The mains/battery option from the "global data" menu produces the following menus.
1:Mains frequency 2:Mains fail action 3:Battery options 4:Charger options
Option 3:Battery options produces
1:Batt mon option 2:Batt connect test 3:Batt hourly test 4:Batt daily test
Option 1 Batt mon option produces
1:Batt low mon 2:Batt very low mon
1. Mains Frequency
The mains frequency can be selected as either 50Hz or 60Hz.
2. Mains fail = fault after 8 hours
The options for this are 1:Yes 2:No 3:Mains disabled.
If this option is enabled, then fault will be signalled when mains has been failed
continuously for 8 hours. This option also allows mains monitoring
to be “disabled”, for
example, when the RDU is externally DC powered.
3. Battery Options
For a mains powered RDU, battery low monitoring and battery connection tests are
required for AS4428.1.
a. Battery monitoring.
There are two options 1:Battery low monitoring and 2:Battery very low monitoring. If
the RDU is being powered from 12V D.C. then these options should be disabled.
If battery low monitoring is enabled, a fault is signalled when a battery low occurs.
For a slim-line RDU with no MAF board, the battery very low threshold is used as the
battery low threshold.
b. Battery connection test.
If enabled, the battery connection will be checked every 30 seconds by reducing the
charger voltage.
c. Hourly battery capacity test.
If enabled, a 90 or 60 second battery test will be done automatically every hour,
starting at five minutes past the hour. If the keypad type is AS4428, this test runs for
90 seconds, otherwise it runs for 60 seconds.
NOTE - a manually initiated battery
test runs for 40 minutes if the keypad is AS4428, otherwise it runs for 60 seconds.
