5.5 Test of output voltage
5.5.1 Float charge (U1)
Ensure that the controller is operating.
Connect a load, approx. 50% of total capacity, to the system.
Check the voltage according to the battery manufacturer's requirements. If the batteries
require a different float charging voltage, adjust the output voltage from the controller. (See
the section for the appropriate controller)
If no change is required, use the following values:
Battery type
Open lead-acid batteries
Valve regulated lead-acid batteries 2.27 V/Cell
Table 5-1 Float/Boost Charge Voltages
5.5.2 Adjustment of Float Charge, U1
Unless otherwise ordered the default output voltage is factory pre-set to 53.5V. The total
voltage has to be in accordance to the number of battery cells.
Please verify number of cells and the battery manufacturers requirement.
Adjust the output voltage from the control unit as necessary.
NOTE
A seal protects the potentiometer in the subrack. Do not break the seal.
5.5.3 Boost charging (U2) (if applicable)
Open lead-acid batteries.
Automatic boost charging - calculation based on the time the battery voltage has been below
certain levels. Automatic activating of boost charging for this calculated time multiplied by
a (boost) factor.
Activate boost charging from the "Set/select U1-U4" menu in the controller.
Return to float charge manually by selecting "U1", or automatically after a pre-set time.
VRLA batteries.
Most of the manufactures of valve regulated lead acid batteries do not recommend boost
charging. If this type of battery is used, the boost function should be disabled.

Boost charging figures
Observe and write down all of the boost charging figures. Parameters to be read/set/
adjusted from control unit or PC with PowCom™ installed.
5.6 Battery supervision
For systems with symmetry cables supplied:
Set the number of battery strings according to the number of battery strings in the system.
The settings are to be made in the control unit via a PC with PowCom™ installed or directly
in the controller (if symmetry failure is indicated).
The symmetry fault alarm can be simulated by pulling out one symmetry cable from the
battery string. Measure that setting to make sure that it is in accordance with the battery
manufacturer's recommendations.
For systems with temp. probe cable supplied:
Temperature compensation is factory pre-set. Check that the temp. probe is activated
and verify that the compensation level is in accordance with the battery manufacturer's
requirements.
(If no compensation level is available from the battery manufacture,
TRANSTECTOR recommends that it is set to 0.5V).
5.7 Battery test
Settings should be made according to the battery manufacturer's requirements, but as a
rule of thumb the following settings can be used for standard VR lead batteries:
No. of test pr. year
=
2
U3 Test
=
1,9 V/cell
End voltage b.test
=
1,94V/cell
Batt. test time
=
40% of expected backup time
Ah limit for test
=
40% of nominal battery capacity
Parameters should be set/adjusted from the controller (Battery test menu) or "Supervision -
Set parameters" menu in PowCom™.
