5.4 Robot Safety System Connections
• To connect an external ‘Emergency Stop Reset’ signal, install a normally open
switch at terminals marked ‘Emergency Stop Reset’ in connector SCB-X13 pin
1-2 as shown in Figure 29 and in principle diagram in Figure 31 .
Important:
The emergency stop reset signal is part of the safety system and has for
this reason a time limit of max. 2.5 seconds. The length of the reset signal must for
this reason not exceed this limit. If exceeded, the enable chain will shut down.
Emergency Stop
Feedback
The external emergency stop feedback connections (chain 1 and chain 2) can be
used to implement the robot’s emergency stop chains into the plant emergency stop
chain. An emergency stop in the robot can thereby be used to activate the plant
emergency stop. The relay switches to be used for this purpose are galvanically
isolated from the rest of the emergency stop chain in the robot. The switches are
closed when the robot emergency stop chains in the robot are OK.
• To include the robot’s emergency stop chain in an external chain, connect the
external chain at terminals marked ‘Emergency Stop Feedback’ (for chain 1 and
2) in connector SCB-X2 pin 9-12 as shown in Figure 29 and in principle diagram
in Figure 31 . Supply voltage should be 24VDC, max 500mA. The external chain
connection must be non-capacitive.
WARNING!
To avoid damage to the internal emergency stop chain in the IRC5P
controller and thereby violate the safety system, the customer must provide
individual monitoring of safety chain 1 and 2 and current limiting at 500 mA in the
external chain.
