5 Battery replacement
F
So that no data is lost, a manual backup must be carried out under "Service" – "Save"
(Save, address: 1:131).
The date, time and all counter readings are then saved in a
non-volatile memory.
(1) Open up the front cover with the electronics and swivel downwards. The battery is now ac-
cessible on the CPU board.
(2) Check whether the size and identification number of the new battery match those on cali-
bration cover plate for the fitted device battery. Normally, the device battery has a black
connecting cable.
(3)
If one or two modem batteries are pre-
sent (here a white connecting cable is
used) and if they have to be replaced,
then this must be carried out first.
(3.1) Pull off the existing modem battery or batteries from the terminals X12 and X13 and
plug on the new battery or batteries to these terminals. The connectors are fitted with
polarity reversal protection and a mech. interlock.
(3.2) Connect the new device battery to the free connector X9 or X10. The connectors are
fitted with polarity reversal protection and a mech. interlock.
(4) Now the old device battery can be pulled off terminal X9 (X10).
(5) Reclose the device (make sure that the cable is not pinched).
(6) Check in the display that no message "3" is entered under "Status"!
(7) The capacity of the new device battery minus about 20% must be re-entered under "Ser-
vice - "Battery capacity" (BAT.C, address: 1:1F3)
Battery identity number: 73015774 --> Entry in the DL210: 13,0 Ah
Remaining battery service life (display: „Bat.R“):
150 Monate
Battery identity number: 73016294 --> Entry in the DL210: 1,6 Ah
Remaining battery service life (display: „Bat.R“):
18 Monate
The entry is also essential even with the same capacity value, so that the computation of the
remaining battery service life is re-initiated.
(8) The voltage figure
3.6V
should be displayed under "Service" – "Modem battery voltage"
(VBatM, address: 4:410).
(9) This successfully concludes the battery replacement.
