7. Test Descriptions
Note :
This test should be done with a "clean" programming card in the monitor (no permissives programmed)
Monitor Response to PASS
:
Each channel pair must put monitor into fault state when the conflict is presented.
RED/WLK/GRN/YEL Single Channel
Test Description :
Line voltage is applied to each RED, WLK, GRN, and YEL input one at a time to verify that a single input will not
cause the monitor to go into the fault state.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. AC line voltage is applied to RED1 for 750ms.
3. AC line voltage is applied to WLK1 for 750ms.
4. AC line voltage is applied to GRN1 for 750ms.
5. AC line voltage is applied to YEL1 for 3600ms.
6. AC line voltage is applied to RED1.
7. Repeat 2 through 6 for each channel.
Monitor Response to PASS
:
Monitor must NOT be found in fault.
YEL Plus RED Interval
Test Description :
Verify that the monitor will go into the fault state if the Yellow change plus Red Clearance interval between the end of
an active Green and the next conflicting Green is less than 2.6 seconds.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. AC line voltage is applied to GRN1 for 2 sec.
3. Turn off GRN1
4. AC line voltage is applied to YEL1 for 2 sec.
5. Turn off YEL1
6. AC line voltage is applied to RED1.
7. Delay 100ms.
8. Turn on an opposing GRN
9. Wait 2 sec.
10. Check fault state.
11. Reset the monitor.
12. Repeat 2 through 7 for all channels
Monitor Response to PASS
:
Monitor must be found in fault on every channel.
GRN/YEL Dual Display
Test Description :
Verify that the Dual Display detection feature is working for each channel.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. Redenable input is active.
3. All RED channels are at 120Vac.
4. Turn off RED1.
5. Turn on GRN1.
6. Turn on YEL1
7. Check for fault.
