NOTICE!
Attention:
The devices should be installed by experts who are trained in wiring electronic
devices. In case of bad wiring, the following problems could occur:
–
On the terminal base, the terminals L+ and M are doubled. If the power
supply is badly connected, a short circuit could happen and lead to a
destruction of the power supply or its fuse. If no suitable fuse exists, the
terminal base itself might be destroyed.
–
The terminal bases and all electronic modules and terminal units are pro-
tected against reverse polarity.
–
All necessary measures should be carried out to avoid damages to modules
and wiring. Notice the wiring plans and connection examples.
NOTICE!
All I/O channels (digital and analog) are protected against reverse polarity,
reverse supply, short circuit and temporary overvoltage up to 30 V DC.
NOTICE!
Attention:
Due to possible loss of communcation, the communication cables should be
fixed with cable duct or bracket or clamp during application.
6.3.1 AC500
6.3.1.1
Power supply for AC500 system
The system is powered by two different power circuits:
● The power supply for the processor module is provided through the terminals L+/M.
● The power supply for the I/O modules is provided through the terminals UP/ZP.
The power supply for the processor module is galvanic isolated from the power supply for the
I/O modules.
As soon as the power supply for the processor module is present, the processor module starts.
The power supply of the processor module and the I/O modules should be powered on the
same time, otherwise the processor module will not switch to run mode after startup.
When during operation the power supply falls below the minimum process and supply voltage
for more than 10 ms, the processor module switches to safe mode. A restart of the processor
module only occurs by switching the power supply off and on again.
If an I/O module is disconnected during operation from the power supply while the processor
module is still powered, the processor module will continue its normal operation on all other
powered peripherals (other I/O modules, communication modules and communication inter-
faces), but freezes the input image. After recovery of the power supply of the affected I/O
module it will continue normal operation and inputs and outputs will be updated.
As power supply for the AC500 system, the ABB power supplies series CP can be used.
6.3.1.2
Power supply for processor modules
The supply voltage of 24 V DC is connected to a removable 5-pin terminal block. L+/M exist
twice. It is therefore possible to feed e.g. external sensors (up to 8 A max. with 1.5 mm
2
conductor) via these terminals.
