5.1
Battery changing
The devices are fitted with an integrated lithium battery for data buffering.
Battery type:
CR2032, 3V / 230mAh
Manufacturer:
e.g. Varta, type 6032
Buffer current:
2µA typ. / 15µA 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.
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.
5.2
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.
5.3
Cleaning
Only mild cleaning agents should be used to clean the front of the unit (e.g. neutral
soap solution or dilute washing-up liquid). Always use a clean, soft cloth for cleaning.
Do not use any cleaning agents that contain granules (e.g. scouring powder or
cleansing milk). These may affect the readability of the display or damage the touch
screen.
Do not use acetone or benzene.
5.4
Usage instructions for touch screens
The touch screen should only be operated with the hand or a specially designed
touch stylus. Using sharp metal objects (e.g. screwdrivers) may damage the touch
screen.
