Ascend Single Phase Charger Operation Manual
Figure 29: Battery History Log Screen
The Battery History Log Screen displays the last 100 battery events. The duration of each event is
formatted to display minutes and seconds.
7.7.3. Equalize Inhibit
Equalize inhibit option (# 155) will prevent the charger from going into Equalize mode. This can be
slaved with a 'Vent Fan Fail' to prevent the Charger to equalize the batteries and contributing to the
batteries gassing hydrogen. A 120 Vac external signal will initiate the Inhibit. An alarm will be registered
in the alarm screen and data log.
7.7.4. Dual Charger Current Limit Control
An optional external signal will reduce the Charger current limit to a secondary level to limit the load on
a source in an emergency. A 120 Vac external signal will initiate the Inhibit. The Charger current limit
can be adjusted through the Setup -> Adjustments -> Dual charger Current Limit screen with an
adjustment range of 10% to 90%.
7.7.5. Communications Package
The optional communications package (# 187) provides Web page and Ethernet/Modbus
communications over RTU and TCP communications to remotely read alarms, voltages, current and
status. The RJ45 connector supports Modbus TCP, Web page, SNMP, and NTP.
Connect 10/100Base-T Ethernet to the RJ-45 Ethernet port of the Charger.
7.7.5.1. Web Page
The web page allows the Charger system to be monitored remotely. The web page can be viewed by
navigation to the IP address of the Charger using a web enabled device. The web page displays meters,
alarms of the system and datalog can be viewed or downloaded.
The buttons appearing along the right side of the Main Screen, except for the Pause/Play button, will
open the window corresponding to which button is clicked. The Alarms button will flash red when there
are active alarms, as will the Pause/Play button when pulling is paused.
