7.5.2 Battery protection cut-off voltage
The purpose of this circuit is to avoid deep discharge and thereby reduced life time of the
backup battery. For normal lead acid accumulators 22V (1.83V/cell) is a reasonable cut-off
voltage.
• Turn O
FF the MAINS switch
• Connect a DC supply, preadjusted to the desired cut-off (
REFERENCE) VOLTAGE and deacti-
vated, to the external charger input on CI 1376. This is called the
REFERENCE SUPPLY.
• Connect a multimeter in DC volt position to the battery input.
• Turn the
REFERENCE SUPPLY On.
• If you measure 0V on the battery adjust the potentiometer on PB1378 until the relay tog-
gles and you measure the
REFERENCE VOLTAGE.
• If you measure the
REFERENCE VOLTAGE, adjust the potentiometer until the relay discon-
nects and you measure 0V.
7.5.3 Battery charger voltage
The cells of a lead acid battery has an optimal voltage when they are fully charged. This volt-
age is greatly dependent on the temperature. The battery life time will decrease if this rule is
not followed. To meet the demand, the internal battery charger(s) in NM 7050, the PS 1375,
has a temperature compensated charging voltage.
Due to current limiting in PS 1375, a discharged battery will firstly be charged with a constant
current, ≈2A with one PS1375 and ≈6A with two PS1375. When the battery draws less than
the current limit, the battery will be charged with a constant voltage (U
BATT
). The factory set-
ting for the internal battery charger is:
U
BATT20
= 27.6V @ 20°C with
.
This is the normal final voltage for lead acid accumulators. If your batteries require a different
final voltage, the adjustment procedure is as follows:
• Turn the B
ATTERY switch OFF and have one TX on .
• Measure the environment temperature T
ENV
(in °C)
• Compute the temperature deviation ∆T = T
ENV
- 20°C
• Compute the new expected final voltage at your environment temperature as
• Adjust the potentiometer on PS1375 until you measure U
BATT
on the 27V test point on CI
1376.
ΤInner Marker uses an external 10 dB attenuator, use 0.2W, 0.1W and 50mW to
calibrate. CARRIER POWER is measured prior to the attenuator, but the soft-
ware will automatically compensate for the 10dB.
Example:
Your battery requires a final voltage of 26V at 20°C, and you have measured an envi-
ronmental temperature of 25°C. You should then adjust the charger to give
