ZGR SWIT NG
The battery charge manager establishes the charging regime in accordance with the number of elements, its type
and battery temperature (optional).
This system has two operating modes:
•
Floating mode. This is the normal operating mode when the battery is charged. The small current which
is supplied to the battery is used to keep this charged and prevent it from self-discharging
•
Rapid charge mode. This is a mode that allows the battery to be fully recharged. During the initial start-
up, the unit always enters in rapid charge mode and after a period of time defined in the factory (by
default, six hours) the ZGR SWIT NG will switch automatically to floating mode.
Once in floating mode, with the battery connected and after a minimum absence of mains supply to the system
(by default, 15 minutes), the unit will switch to rapid charge mode.
OPTIONALLY, a battery temperature compensation probe is available for the ZGR SWIT NG. In accordance with
the atmospheric temperature of the battery, its voltage will vary 2 mv per degree centigrade per element (by
default).
Taking a temperature of 20 º C as reference:
•
a lower output voltage corresponds to an atmospheric temperature of above 20 º C ,
•
in the opposite case, it rises, the maximum output voltage limit being determined by:
In other words, 1 V. under the activation voltage of the "maximum output voltage" alarm.
The charge current limitation depends on the type of battery used. By definition, the limitation values are C/10 for
Pb batteries and C/30 for Ni/cd, considering C to be the capacity of the battery.
The battery load current (Ibat), is between 0,2 and 20 A (depending on the model).
The battery discharge current is limited by the battery circuit breaker and this current must not exceed 20 A.
In the same way, the circuit breaker (see the photograph in the following section) allows the battery circuit to be
opened or closed (see start-up procedure of the ZGR SWIT NG).
3.3 Controls
The SWIT NG allows the operational
status of the system to be displayed. For
this
purpose,
it
has
(OPTIONAL) for load voltage and current.
At a system level, it has local signalling by means of 5 LEDs (4 red and 1 green) that indicate the following
statuses:
•
Rectifier defect: Rectifier/charger failure (see section 7.1).
