Very Low Voltage Alarm (VLVA)
Set the VLVA alarm to a voltage that, if charger output voltage falls below this setting, an alarm will be
annunciated.
High Battery Temperature Alarm (HBTA)
Set the HBTA alarm to a temperature that, if the battery temperature rises above this setting, an alarm will
be annunciated. The temperature compensation (option 2) must be purchased and installed in order for
this alarm to work. If this option is installed the battery temperature can be found in the “Battery
Temperature” menu as shown in Fig. 4-2.
Rectifier Fail Alarm (RECTF)
Gives a RECTF alarm, if enabled, if both an alarm that can cause a rectifier failure alarm (RECT) is
enabled and the alarm is active.
AC Fail Alarm (ACF)
Gives an ACF fail alarm when the AC power to the charger is missing.
Alarm Mode Latching
In the enable mode this allows alarms to be latched in the alarm state until an operator clears them by
pressing any key on the key pad. In the disable mode, the alarms clear once the alarm condition has
cleared.
