2.8.1 Additional Logic Functions
Other logic functions are slight variations of the general AND logic rule set.
• Two-Hand Control: The machine initiation signal incorporating a 0.5 second actuator simultaneity limit and anti-tie-down logic, de-
signed to prevent single-actuator machine cycle operation.
• Safety Device Muting: The automatic suspension of one or more safety input Stop signals during a portion of a machine operation
when no hazard is present or when access to the hazard is otherwise safeguarded.
• Safety Device Bypass: The manually activated, temporary suspension of one or more safety input Stop signals when the hazard is
otherwise safeguarded.
• Enabling Device Control: The actively controlled manual suspension of a Stop signal during a portion of a machine operation when
a hazard could occur.
• Cancel OFF-Delay: The option to cancel a configured OFF-delay time by either keeping the Safety Output ON, or turning it OFF
immediately.
The rules that apply to these special cases are explained in section 10 Input Device and Safety Category Reference on page 90.
2.9 Password Overview
To provide security, the Safety Controller requires use of a password in some cases. For information about changing a Controller’s pass-
word, refer to sections
5.1.4.6 Changing the Password Using the Personal Computer Interface (PCI) on page 61 and 6.3.4 System
Options on page 66. If the password becomes lost, contact the Factory for assistance.
Creating a Configuration
• Via computer using the Safety Controller PC Interface (PCI) program (no password needed)
• Via the Controller Onboard Interface (OBI) (password needed)
Confirming a Configuration
• Via the PCI, using the PC connected to a powered Controller (password needed)
• Via the OBI, on a powered Controller (password needed)
Sending a Confirmed Configuration to the Controller
• Via a direct connection between the PC and the Controller, using the SC-USB1 cable and the PC Interface program (password nee-
ded)
• Via the PC, the XM card programming tool, and the XM card (password needed)
2.10 Confirming a Configuration
Although a Controller will accept an unconfirmed configuration, it will only activate it (adopt the configuration and function according to its
parameters) after the configuration is confirmed, using the OBI or PCI.
IMPORTANT: If any modification is made to a confirmed configuration, or if a configuration is edited during the confirmation
process, the PCI and the Controller will recognize this modified configuration as being new and will require it to be confirmed
before it can be activated and used.
Once confirmed, a configuration can be stored and reused without reconfirmation. The configuration code will be validated automatically
each time it is downloaded to a Controller and whenever the Controller powers up. Configurations, confirmed or not, can be sent via
email. Sending (downloading) a new confirmed configuration to a Controller requires entry of the Controller password.
