Power connections
A socket selector can be powered in 3 different ways:
Atlas Copco Power Supply 8432 0840 00
Power-over-Ethernet (PoE) , that is supplied from the factory Ethernet network, from a controller or from an upstream device (injector or other selector).
An 18 V or 36 V Li-ion Atlas Copco tool battery of type SRB. The battery option is only applicable for models that are equipped with the mobility module for a wireless connection.
Daisy chain length | Battery type | |
|---|---|---|
18V | 36V | |
1 | 10h | 24h |
2 | 6h | 12h |
3 | 2h | 6h |
The power selection depends on the workplace environment and the available network topologies.
Power battery replacement
This section is only applicable for models that are equipped with the mobility module for a wireless connection.
If the selector is assigned to a Virtual Station and the battery is replaced, it the WLAN link is kept alive during the short battery switching time (with a maximum of 30 seconds).
Power over Ethernet
It is possible to use an Ethernet cable for communication and power feeding using the standardized Power-over-Ethernet (PoE) concept. A selector can be directly connected to a controller or a network that is PoE enabled, and the device does not need any external power supply.
When more selectors are needed, they can be interconnected in a daisy chain and use PoE. The first socket selector in a chain supplies the power to the downstream selectors. The power in the PoE link has limitations and it is possible to connect up to 3 socket selectors in a chain. If more than 3 selectors are used in a daisy chain, every 4th socket selector needs an additional Atlas Copco PSU to support PoE to another group of 3 selectors.
A | First selector in a daisy chain configuration, supplies power to downstream devices The first selector in a daisy chain has a wireless connection to the factory network | B | Selector number 3 in a downstream chain; last unit that can be powered by upstream unit number 1 with PoE |
C | Socket with external power, number 4 in the daisy chain Power must be supplied from an external DC source | D | Atlas Copco external power supply |
E | Link between socket selectors including communication and power using PoE connectivity | F | First selector in a daisy chain configuration, supplies power to downstream selectors The selector is powered from a controller or from a network with PoE capability |
G | PoE cable from controller A controller that is PoE enabled | H | Socket with external power, number 4 in the daisy chain Power must be supplied from an external DC source |
This concept is applicable regardless if the chain of socket selectors is connected to the factory network, directly connected to the controller or powered by a battery with a wireless connection.
Using too many selectors in a PoE daisy chain, i.e. using 4 or more socket selectors, will cause all selectors to enter a reboot cycle until the faulty configuration is fixed.
A socket selector that is battery powered can always be connected to an external DC power supply and operate normally. Connecting an external power supply to a battery powered selector, will not charge the battery as the selector has no integrated battery charger.
External DC power supply
A selector can always be connected to, and powered by, an external DC power supply regardless if it is installed and configured in a system architecture for PoE or battery power.
Old Power Focus 6000 controllers
The previously described scenario requires a controller that is equipped with PoE connector. Early controllers do not have this port.
A standard component, a PoE injector, combines the power with the ethernet communication. A special Atlas Copco supplied cable connects between the Power Focus controller com port and the RJ45 connector in the PoE injector. A standard cable with RJ45 and M12 connectors couples between the injector and the socket selector.
A | Controller connected to factory network | B | First socket selector in a daisy chain configuration; supplies power to 3 downstream selectors |
C | Standard cable between RJ45 and M12 connectors, supporting PoE | D | Socket selector number 4 in the daisy chain needs external power and can supply power through PoE to downstream devices |
E | Power supply unit for selector | F | Link between socket selectors including communication and power using PoE connectivity |
G | From 24V out screw terminal in PF6000 to the MOXA INJ-24 power supply in. | H | PoE injector; MOXA-INJ24 |
I | Adapter cable from controller com port to support ethernet communication to RJ45 connector Used for a controller that is not PoE enabled |
