SC22-3 Safety Controller
Instruction Manual
System Checkout Procedures
17 .
□
Bypass Function (with Mute)
□
Verify that each safety input, if it is both mutable and can be bypassed, is in the Stop state .
• If the SC22-3 is still muting, the associated safety outputs should remain ON . Even if the timer expires and the outputs turn
OFF, go to the next step .
□
Activate one or both mute sensors in a mute sensor pair . If there are two mute sensor pairs, at least one sensor in one of the
pairs must be activated .
• Verify that the mute lamp, if used, is flashing .
□
Verify that when the bypass switch is in the Run state:
• The associated safety outputs turn ON .
• The mute lamp, if used, is now steady ON .
• The associated safety outputs turn OFF when the bypass timer expires .
□
Verify that when the bypass switch is in the Stop state and goes back into the Run state:
• The associated safety outputs turn ON .
□
Verify that when all other non-bypassed inputs associated with the same output are in a Stop state, one at a time:
• The associated safety outputs turn OFF while the input is bypassed .
18 .
□
Bypass Function (without Mute)
□
Verify that when the safety input to be bypassed is in the Stop state:
• The associated safety outputs are OFF .
□
Verify that when the bypass input is in the Run state:
• The associated safety outputs turn ON .
• The associated safety outputs turn OFF when the bypass timer (backdoor timer) expires .
□
Verify that when the bypass switch is in the Stop state and goes back into the Run state:
• The associated safety outputs turn ON .
□
Generate a stop command from the non-bypassed safeguarding device(s), one at a time .
• Verify that the associated safety output(s) turns OFF while the input is bypassed .
19 .
□
Enabling Device Function
□
Verify that all inputs associated with the same output as the enabling device are in the Run state to turn the output(s) ON . The
enabling device is to remain in the Stop state .
• Verify that the associated safety outputs are ON .
□
Verify that when the enabling device is in the Run state:
• The associated safety outputs remain ON and the LCD displays
ENABLE MODE
.
□
Verify that when the enabling device is in the Stop state:
• The associated safety outputs turn OFF .
□
Verify that when the enabling device is in the Run state:
• The associated safety outputs turn ON .
• The associated safety outputs turn OFF when the enabling device timer expires .
□
Verify that when the enabling device is in the Stop state and goes back into the Run state:
• The associated safety outputs turn ON .
□
Verify that when all E-stop and rope-pull inputs associated with the same outputs are in the Stop state, one at a time (repeat
step for each device, as needed):
• The associated safety outputs turn OFF while in Enable mode .
□
Verify that the enabling device is in the Stop state and then apply a system reset .
• Verify that the LCD no longer displays ENABLE MODE .
• Verify that the Safety Controller is back to normal operation .
