7. Test Descriptions
Test Sequence :
1. Monitor is powered up in quiescent state.
2. Conflict is created on GRN1 and GRN 2.
3. Delay for less than 200ms.
4. Conflict is removed.
5. After 250ms delay, check for fault state.
Monitor Response to PASS :
For conflict lasting less than 200ms, monitor not found in fault state.
Conflict Detect Timing
Test Description :
Verify that the monitor recognizes a conflict lasting more than 450ms.
Test Sequence :
1. Monitor is powered up in quiescent state.
2. Conflict is created on GRN1 and GRN 2.
3. Delay.
4. Conflict is removed.
5. After 250ms delay, check for fault state.
6. Increase Delay and repeat 3,4 and 5 until monitor is found in fault.
7. Record Delay time.
Monitor Response to PASS :
For conflict lasting greater 450ms, monitor must be in fault state.
Conflict Latching
Test Description :
Verify the detection of a conflict is latched through an AC power loss.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. A conflict is created with GRN1 and GRN2.
3. AC power is removed.
4. Conflict condition is removed.
5. Delay 5 seconds.
6. AC power is reapplied.
Monitor Response to PASS :
Monitor must still be in fault state when AC power is reapplied.
Redfail Ignore Timing
Test Description :
Verify that Redfail lasting less than 700ms is ignored.
Test Sequence :
1. Monitor is powered up in quiescent state.
2. All RED channels are at AC line voltage.
3. RED1 is turned off for less than 700ms.
4. Check for fault state.
Monitor Response to PASS :
RED1 off for less than 700ms must not cause fault.
