6. Battery warnings
Each half cylinder has a battery management system that indicates declining battery
power in good time. This helps prevent the batteries from becoming completely dis-
charged. The battery warning levels are described in the following.
6.1 Half cylinder
Warning level 1: weak batteries
When a half cylinder's batteries are running low it will emit eight short signal
tones in rapid succession when operated by a transponder before the cylinder
engages. The batteries should be replaced without delay. Around 15,000
opening or 9 months use of the half cylinder remain after battery warning 1
has been triggered.
Warning level 2: extremely weak batteries
If the batteries are allowed to discharge even further, subsequent transponder
operation will induce a succession of short signal tones lasting approximately
30 seconds before the cylinder engages.
The cylinder will not engage until af-
ter the acoustic signal has ended. The batteries are now virtually completely
discharged. It is imperative they are replaced as soon as possible.
Emergency battery - warehouse mode:
A half cylinder that has indicated battery warning level 2 will remain active for
approximately another 50 operations, or it will shut down completely after ap-
proximately 30 days if not used. In both cases the half cylinder will revert back
to the so-called emergency battery - warehouse mode. The half cylinder can
now only engage with the help of a programming device (see chapter 6.1.3).
Batteries can be changed at any time when the half cylinder is in emergency
battery - warehouse mode.
