SC22-3 Safety Controller
Instruction Manual
System Checkout Procedures
NOTE: If any of the status outputs are mapped to functions within the configuration, monitor the function of each status output as the associated
operation is tested .
1 .
□
Configure the machine so that the indicators for the safety outputs (SO1, SO2, and SO3) of the Safety Controller and for the
associated output devices can be observed and verified to operate correctly and without risk of injury .
Do not apply power to the Safety Controller or to the guarded machine now.

Safety System and Safeguarding Device Checkout
A .
□
Verify that the guarded machine is of a type and design compatible with this safeguarding system, as described on page 1 .
B .
□
Verify the installation and perform the checkout procedures for the external safety/safeguarding systems and devices
connected to the SC22-3 inputs as described by the appropriate manuals . Do not proceed until all checkout procedures are
completed successfully and all problems have been corrected .
C .
□
Verify that:
• Access to any dangerous parts of the guarded machine is not possible from any direction not protected by the safeguarding
system, hard guarding, or supplemental safeguarding, and that
• Supplemental safeguarding and hard guarding, as described by the appropriate safety standards, are in place and
functioning properly .
D .
□
Verify that all Reset switches are mounted outside and in full view of the guarded area, out of reach of anyone inside the
guarded area, and that means of preventing inadvertent use is in place .
E .
□
Examine the electrical wiring connections between the SC22-3 Controller’s OSSD outputs and the guarded machine’s control
elements to verify that the wiring meets the requirements stated in Section 3 .6 .
3 .
□
Verify that all two-hand control devices, enabling devices, muting sensors, and bypass switches are in the inactive (Stop) state .
NOTE: In all cases, outputs associated with a two-hand control device should not turn ON at power-up . Also, bypass or enabling
devices in the active (Run) state at power-up will not function until they are seen as OFF first .
4 .
□
Ensure that all other input devices are in the active (Run) state .
Power-Up and Reset Functions
5 .
□
Ensure that no individual is exposed to the hazardous motion/situation of the guarded machine during the checkout procedure .
Observe the SO status indicators or the messages on the front panel display to verify whether a safety output is ON or OFF .
Apply power to the Safety Controller and all input devices that require power, but not to the guarded machine.
6 .
□
Verify that the configuration file (e .g ., revision level) is appropriate for the application . At a minimum, have a copy of the
Configuration Summary from the PC Interface software available for reference during the checkout procedure .
7 .
□
Verify that status outputs configured for a monitored mute lamp (if used) turn ON briefly (i .e ., flash) after power-up .
8 .
□
Power-Up Configuration (see “System Settings” in the Configuration Summary)
If configured for Normal Power-Up (default): Verify that safety outputs associated only with device inputs configured for automatic
reset turn ON .*
If configured for Automatic Power-Up: Verify that all safety outputs turn ON* within 5 seconds (outputs with a configured ON-
delay may extend this time) .
If configured for Manual Power-Up: • Verify that all safety outputs remain OFF .
• Wait at least 10 seconds after power-up, then apply a system reset .
• Verify that safety outputs turn ON* even if an associated non-safety input is configured for a
manual reset .
* NOTE: In all cases, safety outputs associated with a two-hand control will not turn ON at power-up . Enabling devices and bypass
functions are not available at power-up — they must begin in a Stop state (OFF) .
