CHAPTER 7: FAULTS
The PBM753 card is able to recognize 4 types of faults :
7.1. BATTERY DISCONNECTION UNDER CHARGE
Disconnection of battery during a charging process
might be dangerous
.
If nevertheless battery is disconnected from charger during a charging process, the charging process will be
temporarily stopped
and a fault will be signalled by means of the yellow L2 LED blinking.
On connecting again a battery to the charger, the card will reset and start a new charging process.
All information concerning the previous charging times go lost.
7.2 CURRENT DELIVERY DURING AN OFF STAGE
During an inactive (not charging) stage the battery charger detects current presence towards battery, and
signals it by means of the
red L4 LED blinking
slowly. This signals a defect either of the relay or contactor.
7.3 FAILURE TO DELIVER CURRENT DURING AN ON STAGE
During an active (charge) stage the battery charger detects current failure towards battery and signals it by
means of the
red L4 LED blinking
quickly.
7.4 SAFETY TIMER
If the safety timer operates during the initial charge, the battery charger stops the charging process and signals
it by means of
the red L4 LED which lights up
constant.
To exit from all fault conditions, the battery charger needs resetting: disconnect the charger from the
power supply and connect it again to it.
