Maintenance and support
6.1
Battery changing
The devices are fitted with an integrated lithium battery for data buffering.
Battery type:
CR2032, 3V / 230mAh coin cells
Manufacturer:
e.g. Varta, type 6032
Buffer current:
2 µA typ. / 15 µA max.
Battery voltage monitoring: yes (functionality dependent on software)
Battery life (typ.) :
5 years
Battery life is basically dependent on the prevailing environmental conditions
(operating temperature, switch-on/switch-off time, humidity). The lifetime given here
assumes that the device is switched on regularly (several times a week / at least
1500 hours a year).
The battery should only be changed by trained specialists. ESD protective measures
should be observed.
Before changing the battery, the device should be disconnected from the power
supply.
The PCD7.D61x0 units do not have to be taken out of the switching cabinet. It is
sufficient to loosen the two screws on the back plate (hexagonal recess, size 2.0)
and open the back plate downwards. Hold the back plate roughly horizontal with one
hand.
Push the battery contacts back with a plastic object (e.g. touch stylus) until the battery
pops out of the holder. Remove the battery. Insert new battery into the battery holder
and clip in place. The positive pole of the battery must point upwards / be visible.
When the battery is changed, the real-time clock data will be lost.
Do not short-circuit the battery contacts. Risk of explosion. Battery should only be
replaced with the same type from the same manufacturer.
Lithium batteries are hazardous waste. Used batteries should be disposed of in
accordance with national guidelines.
6.2
Replacing background lighting
It is advisable to allow Saia-Burgess Controls AG to replace the tubes for the
background lighting. The projected lifetime of the tubes can be found in the Technical
Data.
The tubes for the background lighting contain traces of mercury and are hazardous
waste. They must be disposed of in accordance with national guidelines.
