Reset Configuration
If configured for Automatic Reset: Verify that the corresponding safety output indicator is ON Green, indicating that the safety
output(s) is ON (assuming that other inputs configured for manual reset are not associated with the safety output; see Manual
Reset) . If the Red status indicator begins to flash at any time, refer to Section 8 for troubleshooting information .
If configured for Manual Reset: Verify that the Green status LED is flashing to indicate that a reset is being requested, and that the
message “Reset Needed” appears on the Diagnostic Display . If the Red status indicator begins to flash at any time, refer to
Section 8 for troubleshooting information .
NOTE: If a “monitored manual reset” has been configured, perform a reset by closing the Reset input for at least ¼ second, but not
longer than 2 seconds, and then reopening the contact . Verify that the Green status indicator comes ON steady .
□
Verify that all reset switches are mounted in full view of the guarded area, but outside it and out of reach of anyone inside the
guarded area, and that means of preventing inadvertent use is in place .
□
Actuate each (non-safety input) manual reset device to turn ON remaining outputs not associated with a two-hand control device .
□
Verify that all safety outputs not associated with two-hand control devices are now ON .
(Exception: An output associated only with an enabling device will remain OFF .)
If a particular function or device is not part of the application, skip that step and proceed to next check or to step 20.
Two-Hand Control Functions
10 .
□
Ensure all inputs are in the ON-state associated with safety outputs and activate each two-hand control device to turn ON the
remaining outputs .
• Verify that the associated safety output remains OFF unless both hand controls are activated within 0 .5 seconds of each other .
• Verify that when one hand is removed and replaced, the safety output turns OFF and remains OFF .
Emergency Stop and Rope-Pull Functions
11 .
□
While the outputs are ON, individually actuate and re-arm each E-stop and/or rope-pull device, one device at a time .
• Verify that each associated safety output turns OFF with the proper OFF-delay, where applicable .
12 .
□
As the E-stop or rope-pull device is returned to the Run state (armed):
If configured for Manual Reset or if associated with a two-hand control device: Verify that the safety output remains OFF .
If configured for Automatic Reset (assuming that another device is not holding it OFF): Verify that the safety output turns ON .
13 .
□
Apply a manual reset and/or activate the two-hand control device as necessary to turn the output(s) back ON .
• Verify that each associated safety output turns ON with the proper ON-delay, where applicable .
Other Stopping Device Functions
14 .
□
Repeat steps 11–13 for each device type below, as applicable:
□
Verify operation of all gate switches .
□
Verify operation of all optical sensors .
□
Verify operation of all safety mats .
□
Verify operation of all protective stops (i .e ., other safety/safeguarding devices otherwise not listed) .
□
Verify operation of all ON/OFF inputs .
