7. Test Descriptions
1. Monitor is powered up in the quiescent state.
2. Redenable is turned off.
3. Delay.
4. A Redfail condition is created.
5. Delay.
6. Check fault state.
Monitor Response to PASS :
Monitor must be found in fault at (6).
50ms Power Interrupt
Test Description :
Verify that the monitor ignores a 50ms AC power loss.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. AC power is removed for 50ms.
3. Delay.
4. Check fault state.
Monitor Response to PASS :
Monitor must NOT be found in fault at (4).
7.3.2
Voltage Tests
RED 70Vrms Sine Wave Recognition
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 Recognition
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.
5. fault state is checked for each channel.
Monitor Response to PASS
:
50Vrms on any RED channel must cause monitor to go into fault state (Redfail fault).
GRN, YEL, 25Vrms Recognition (Sine Wave, Positive Rectified, Negative Rectified)
Test Description :
Verify that the monitor recognizes a signal greater than 25Vrms as being "on" for every GY channel.
