System Checkout Procedures
If Mute, Bypass and/or Enabling Device functions are not used, proceed to step 20.
15. □
Mute Functions
□ While the outputs are ON, initiate a mute cycle by activating the mute enable input (if used) and then activate each mute sensor
of a pair within 3 seconds.
• Verify that the mute lamp, if used, turns ON.
□ Generate a stop command from the safeguarding device that has been muted.
• Verify that the associated safety outputs remain ON (Green status indicator remains ON).
• If a time limit (backdoor timer) is associated with the mute, verify that the associated safety outputs turn OFF when the mute
timer expires.
□ Repeat above steps for each muting sensor pair.
• Verify proper operation with each associated muted device.
□ Generate a stop command from the non-muted safeguarding device(s), one at a time.
• Verify that the associated safety outputs turn OFF while the muted input is muted.
NOTE: The mute function will end when an associated output turns OFF for any reason. In order to complete this test with the other
non-muted safeguarding devices, a new mute cycle must be initiated for each one.
16. □
Mute on Power-Up Option
□ Turn the SC22-3 power OFF.
• Activate the mute enable inputs (if used).
• Activate an appropriate muting sensor pair for starting a mute cycle.
• Ensure all input devices are in their Run (active) state (not including two-hand control devices).
• Verify that all enabling devices and bypass switches are in the Stop (inactive) state.
□ Verify proper operation at power-up.
□ If configured for Auto Power-Up:
• Verify that all safety outputs turn ON*.
• Verify that the mute status output (if used) turns ON.
□ If configured for Normal Power-Up:
• Verify that all safety outputs associated with only auto-reset devices or mutable manual-reset devices turn ON*.
• Verify that the mute status output (if used) turns ON.
□ If configured for Manual Power-Up:
• Verify that all safety outputs remain OFF.
• Wait at least 10 seconds after power-up and apply a system reset.
• Verify that all safety outputs turn ON*.
• Verify that the mute status output (if used) turns ON.
*NOTE: In all cases, safety outputs associated with a two-hand control device will not turn ON at power-up. The Mute on Power-Up
feature does not apply to mutable two-hand control devices.
□ Generate a stop command from the safeguarding device that has been muted.
• Verify that the associated safety outputs remain ON (i.e., the input is muted); the Green status indicator should remain ON.
