PSU CUSTOMISATION
The BF560-24/E can be optionally customised to suit your exact requirements using a BF423 configurator and PC. Configurable parameters include Float voltage temperature compensation; Battery charge rate (mA); Battery impedance; Configurable Input/Output settings.
PSU STATUS LED (located on the PSU PCB)
1 flash = Mains Failure.
2 flashes = Battery Voltage Low.
3 flashes = Battery Voltage Critical.
4 flashes = Charger Failure.
5 flashes = Charger OK (Battery is either actively charging, or in float charge).
6 flashes = No Batteries Fitted (indicating DIP Switch 4 position).
7 flashes = Battery Resistance Fault (Level set by DIP Switch 2 position).
8 flashes = Output Over Voltage.
BATTERY FAULT MONITORING
The BF560-24/E monitors battery resistance to the requirements of EN54-4/A2. The fault threshold is directly related to the ability of the battery to deliver the rated current to the load. For example, batteries stored uncharged for long periods, during shipment and/or distribution, degrade leading to increased internal resistance. If a degraded battery is fitted, a fault will be shown by the PSU as mandated by EN54-4/A2.
DATA PORT
Data on the BF560-24/E’s status can be extracted from the PSU’s bi-directional data port. The data available includes thermistor measurements; battery terminal voltage; system voltage at load terminals; battery charge current; load current; battery impedance and ASCII text string status messages. Extracting this data requires additional equipment and permissions.
