Programmable Safety Controller SCR P
12 Troubleshooting
The Safety Controller is designed and tested to be highly resistant to a wide variety of electrical noise sources that are
found in industrial settings. However, intense electrical noise sources that produce EMI or RFI beyond these limits may
cause a random trip or lockout condition. If random trips or lockouts occur, check that:
•
The supply voltage is within 24 V dc ± 20%
•
The Safety Controller's plug-on terminal blocks are fully inserted
•
Wire connections to each individual terminal are secure
•
No high-voltage or high-frequency noise sources or any high-voltage power lines are routed near the Safety
Controller or alongside wires that are connected to the Safety Controller
•
Proper transient suppression is applied across the output loads
•
The temperature surrounding the Safety Controller is within the rated ambient temperature (see

Unable to move a block to a different location
Not all blocks can be moved. Some blocks can be moved only within certain areas.
•
Safety Outputs are placed statically and cannot be moved. Referenced Safety Outputs can be moved
anywhere within the left and middle areas.
•
Safety and Non-Safety Inputs can be moved anywhere within the left and middle areas.
•
Function and Logic blocks can be moved anywhere within the middle area.
SC-XM2/3 button is unavailable (grayed out)
1. Make sure all connections are secure—SCR P-PA to the USB port of the computer and to the SCR P-FPS drive.
2. Verify that the SCR P-PA Programming Tool is installed properly—see
