If the currently measured temperature value is below (6.6), then this value is used for temperature
compensation. If the currently measured temperature value is above (6.7), then this value is used for
temperature compensation.
6.5 Measuring system
6.5.1 Assignment measured values
In this menu it is possible to assign an user-
defined input parameter to each individual
measurement value of the UPC4. For
example: Battery current = input BU1 I1.
Please see the following examples:
1. example
: Three batteries are used, but
only one measuring line from terminal V1
of the BU is connected to battery 1 for
voltage monitoring.
In this case at “Voltage Vbatt”, "Battery 1"
and "Bat
tery2" you can assign the same
measurement source as for "Battery1".
Voltage Battery 1= BU1_V1
Voltage Battery 2= BU1_V1
Voltage Battery 3= BU1_V1
2. example:
Two batteries are available but only one battery shunt is connected.
2a)
The battery shunt is series connected to both batteries. It is connected to input I1 of the first
Basic-Unit (BU1).
In this case the measured current is the total battery current.
Current Ibatt, battery 1= BU1_I1
Current Ibatt, battery 2= undefined
2b) The battery shunt is connected within one battery string.
In this case the measured current is the current of Battery 1. But the same input can be assigned to
batter
y 2 because it is assumed that the same current is withdrawn from battery 2.
Current Ibatt, battery 1= BU1_I1
Current Ibatt, battery 2= BU1_I1
