3.1.4 Changing the battery in the measuring system
The battery to be replaced is located inside the base under the flange cover (see Figure ).
The robot is delivered with a rechargeable Nickel-Cadmium (Ni-Cd) battery with article
number 4944 026-4.
The battery must never be just thrown away; it must always be handled as hazardous waste.
• Set the robot to the MOTORS OFF operating mode. (This means that it will not
have to be coarse-calibrated after changing the battery.)
• Remove the flange cover. All connections on the flange cover, except for the sig-
nal
contact for the serial link, R1.SMB, can be disconnected.
• Remove one of the screws and loosen the two other screws holding the serial
measurement board. Push the unit to the side and remove it backwards. All
cables and contacts must remain intact. Note the ESD-protection (ESD = Electro-
static Discharge).
• Loosen the battery terminals from the serial measuring board and cut the clasps
that keep the battery unit in place.
• Install a new battery with two clasps and connect the terminals to the serial mea-
suring board.
• Refit the serial measurement board, flange cover and connections.
• The Ni-Cd battery takes 36 hours to recharge; the mains supply must be switched
on during this time.
The Battery is located Inside the Base under the Flange Cover.
Alternative
Battery As an alternative to the Ni-Cd battery a lithium battery of primary type can be installed. The
lithium battery needs no charging and has for that reason a blocking diode which prevents
charging from the serial measurement board.
The benefit with a lithium 10.8 V battery is the lifetime, which can be up to 5 years in service,
compare with the Ni-Cd battery’s maximum life time of 3 years in service.
Two lithium batteries exists:
• A 3-cell battery, art.No. 3HAB 9999-1
• A 6-cell battery, art.No. 3HAB 9999-2
The life time of the lithium battery depends on how frequently the user switches off the
power. The estimated max. life time in years for the different lithium batteries and the recom-
mended exchange interval is shown below:
