,
WHAT
PARAMETERS DO
I
USE
?
A. Correct parameters for battery current limit are specified by a battery manufacturer, in a datasheet. It
improves the battery lifetime and protects from overcharging. Caution: Incorrect setting might cause
unexpected system operation.
3.9.1.8 Q:
S
HOULD THE BATTERY TEMPERATURE COMPENSATION BE ACTIVATED
?
A. The battery temperature compensation is an optional feature, which consists of a temperature sensor
with wires for specified length for external or going into the unit for internal batteries. It connects to the
rear side of the controller, to a green plug with its own specific connection. Before enabling this feature,
make sure you have it in your system.
3.9.1.9 Q:
W
HY SHOULD
I
USE THE BATTERY TEMPERATURE COMPENSATION
?
W
HAT IS
THE CORRECT VALUE
?
A. The battery temperature compensation should be corrected according to the battery manufacturer
’
s
recommendations; it protects the batteries form overcharging in a high temperature environment.
3.9.1.10 Q:
W
HEN THE
A
H VALUE FOR THE BATTERIES IS ENTERED
,
AND THERE ARE TWO
OR THREE BATTERY CABINETS SELECTED
,
WILL THE UNIT ADD THE ENTERED
VALUES OR DIVIDE THEM BETWEEN THE CABINETS
?
A. If the number of battery cabinets is set to more than one, then you will have to select the battery Ah
rating for each battery cabinet independently, as it can be different. Eventually the unit will add these
values and obtain the global Ah value.
3.9.2 GENERAL

LUS UNIT HAVE EQUALIZING
(

)
MODE
?
A. Gamatronic UPS systems do not use equalizing (boost) battery charging. If you have equalizing menu
entry in your controller menu, please arrange software version upgrade for your controller.
3.9.2.2 Q:
W
HAT WILL HAPPEN TO THE UNIT IF THE SYSTEM CONTROLLER IS REMOVED
?
A. When the controller is removed, the system will continue with normal operation, including battery
charging and backup operation upon power failure. It will also start normally when mains power is turned
on.
3.9.2.3 Q:
C
AN
I
USE THE SYSTEM WITHOUT SYSTEM CONTROLLER MODULE AT ALL
?
A. Yes, the UPS system will provide the basic functionality; however, many important features will not be
available. Major features include battery test, measurements, control etc. Without a system controller the
system will function as a rectifier, batteries and an inverter (with ST/SW) only with no additional features.
This kind of operation is not recommended.
