Figure 121: Setup: Inputs without Bypass
Bypass Function
1. Verify that the associated Safety Outputs are Off when the safety inputs to be bypassed are in the Stop state.
2. Verify that when the Bypass Switch is in the Run state:
a) The associated Safety Outputs turn On.
b) The associated Safety Outputs turn Off when the bypass timer expires.
3. Change the Bypass Switch to the Run state and verify that the associated Safety Outputs turn On.
4. One at a time, switch the non-bypassed input devices to the Stop state and verify that the associated Safety
Outputs turn Off while the Bypass Switch is in the Run state.
Safety Output Off-Delay Function
1. With any one of the controlling inputs in the Stop state and the delayed Safety Output in an Off delay state, verify
that the Safety Output turns Off after the time delay is over.
2. With any one of the controlling inputs in the Stop state and the Off Delay timer is active, switch the input to the Run
state and verify that the Safety Output is On and remains On.
Safety Output Off-Delay Function
—Cancel Delay Input
With the associated inputs in the Stop state and the delayed Safety Output in an Off delay state, activate the Cancel
Delay input and verify that the Safety Output turns Off immediately.
Safety Output Off-Delay Function
—Controlling Inputs
1. With any one of the controlling inputs in the Stop state and the delayed Safety Output is in an Off delay state, switch
the input to the Run state.
2. Verify that the Safety Output is On and remains On.
Safety Output Off-Delay Function and Latch Reset
1. Make sure the associated input devices are in the Run state so that the delayed Safety Output is On.
2. Start the off delay time by switching an input device to the Stop state.
3. Switch the input device to the Run state again during the Off-Delay time and push the Reset button.
4. Verify that the delayed output turns Off at the end of the delay and remains Off (a latch reset signal during the delay
time is ignored).
