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™.

5.8 Commissioning record
This is a step-by-step commissioning record for easy commissioning of Power Supply
Systems. Do not continue if any faults occur during this commissioning. The checkpoints
are to be considered as a minimum for commissioning of the system.
1
Check that the rack is level
2
Check that all breakers are turned to "off"
position and that no rectifiers are mounted in the
subrack(s).
3
Connect AC, and measure voltage on the mains
input connections in the cabinet, Is to be 120V or
230V AC (Measure 120V or 230V from phase to
N when 208V or 400V mains input is used)
4
Mount the rest of the rectifiers
5
After connection of battery, verify right polarity by
measuring the voltage drop across the battery
breakers (normally not more than 5V DC).
6
Check float charge, U1, and boost charge, U2.
It is to be adjusted according to the battery
manufacturers requirements.
7
Check temperature compensation. It is to be
adjusted according to the battery manufacture
requirements.
Check temperature read from the controller
compared to the ambient temperature.
8
Check symmetry measurement and set number
of battery strings according to actual number of
supervised battery strings in the system.
9
Check alarm transmission by running an alarm
test.
