Safety Summary
(continued)
SPECIFIC Page 114: It is not possible to change the CI852 unit via hot swap and it is
CAUTIONS not allowed to perform an online upgrade of firmware in a system contain-
(continued) ing CI852.
Page 118: Hot swap is supported for CI854A (not CI854).
Page 133: – 115 V for 110 – 120 V AC – 230 V for 220 – 240 V AC
(default position on delivery).
Page 141: To avoid error indications from SA/SB when single power sup-
ply is used, it is recommended to connect the input terminals SA/SB on
the CPU to +24 V, see Figure 47.
Page 143: Do not connect the TK821V020 cable until the AC 800M Con-
troller has been powered-up normally and the memory back-up function
has been activated, that is, the B(attery) LED flashes. If no normal power
supply is connected to the PM8xx processor unit, the CPU memory will
immediately start to consume battery power when the cable is connected.
Page 157: When setting the IP address of the primary CPU in Control
Builder, the backup CPU must be turned off (powered down). Otherwise
the backup CPU will take over and you get disconnected.
Page 159: Note that the electrical ModuleBus can only be used for con-
nection of S800 I/O when AC 800M is running in single CPU configura-
tion.
Page 184: Note that a Backup CPU with severe communication errors on
the ModuleBus will be rejected (if ModuleBus is part of the HW configura-
tion) and synchronized state will never be reached as long as error
remains.
Page 189: The RCU Link Cable must NEVER be removed from the pri-
mary Processor Unit during redundant operation. Removal of the cable
may cause the unit to stop.
Page 192: Due to the batteries being connected in parallel, it is necessary,
when using the SB821 external battery, to remove the internal battery
from the PM8xx in order to avoid reducing available memory back-up time.
