Battery
The minimum capacity battery to supply the PSU is 1 x 7 Ah. The maximum capacity
battery is 2 x 17 Ah.
Battery test
A battery test on full load is automatically performed once an hour and during the Engineer
Mode exiting procedure. If the battery voltage falls to 10 V while the Power Supply Unit is
running on the battery, then it is automatically disconnected to prevent deep discharge of the
battery.
Smart battery monitoring
The total current used in the system is constantly measured and reported to the control panel
in the PSU Comms [61.4] menu option.
Configuration
Addressing for either variant is identical to that described for RIO Modules. Set the address
u
sing the rotary switch before applying power.
The 4 outputs are switched 0 V (0 V active). Without the jumper links (LK1-4) fitted, the
outputs float in the OFF state. They can apply a +12 V signal, if required, by fitting the
appropriate pull-up jumper supplied.
Fit LK5 if you do not intend to use an off-wall tamper.
For normal operation, ensure that the SLAVE and E/E links are in place.
There are three open-collector, normally off, output fault signals:
FAULT OP AC activated by an a.c. failure.
FAULT OP BAT activated by a battery low or battery fail condition.
FAULT OP PWR activated by low voltage present in +12V1, +12V2.
