7. Test Descriptions
Redfail Detect Timing
Test Description :
Verify that Redfail lasting less than 700ms is ignored Redfail lasting more than 1000ms causes fault
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.
5. RED1 is turned off for incrementally longer periods until fault state is found.
6. RED1 off time is recorded.
Monitor Response to PASS :
RED1 off for greater than 1000ms must cause fault.
Redfail Latching
Test Description :
Verify that a Redfail condition is latched through an AC power failure.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. All RED channels are at AC line voltage.
3. A Redfail fault is created with RED1.
4. AC power is removed for 5 seconds.
5. RED1 is turned back on.
6. AC power is reapplied.
Monitor Response to PASS :
Monitor must go to fault state on Redfail fault. Monitor must still be found in fault state after AC power is removed,
RED1 turned back on, and AC power is reapplied. (Redfail fault must be latched through power failure.)
7.1.2
Voltage Tests
RED 70Vrms Sine Wave
Test Description :
Verify that a sine wave greater than 70Vrms is recognized as being "on" for every RED channel input.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. Redenable input is activated.
3. A sine wave greater than 70Vrms is applied to each RED channel.
Monitor Response to PASS
:
Monitor must NOT be found in fault state.
RED 50Vrms Sine Wave
Test Description :
Verify that a sign wave less than 50Vrms is recognized as being "off" for every RED channel input.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. All RED channels are at AC line voltage.
3. Redenable input is activated.
4. A sine wave less than 50Vrms is applied to each RED channel one at a time.
