7. Test Descriptions
2. Monitor AC power is turned off.
3. Delay
4. Monitor AC power is turned on.
5. Fault state is checked.
6. Increment delay time and repeat 2 and 5 until monitor is found in the fault state.
Monitor Response to PASS :
Loss of AC power for greater than 500ms must cause fault.
Initial Flash
Test Description :
Verify that the initial flash time setting of the monitor is within the limits.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. AC power is removed for 5 seconds.
3. AC power is reapplied.
4. The monitor Initial Flash (fault state) time is measured.
Monitor Response to PASS :
Initial Flash time is rounded to the nearest second and must be greater than or equal to 4 seconds and less than or
equal to 11 seconds.
Start Delay
Test Description :
Verify that the Start Delay output is active when power is initially applied to the monitor.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. AC power is removed for 5 seconds.
3. AC power is reapplied.
4. The active time of the Start Delay output is measured.
Monitor Response to PASS :
Start Delay output active for greater than or equal to 1.5 seconds and less than or equal to 3.5 seconds.
DC1 (or DC2) Failure Ignore
Test Description :
Verify that the monitor ignores a loss of DC power lasting less than 125ms.
Test Sequence :
1. Monitor is powered up in the quiescent state.
2. DC power (24V) is turned off for less than 125ms.
3. Delay 250ms.
4. Fault state is checked.
Monitor Response to PASS
:
Loss of DC power for less than 125ms must NOT cause the monitor to go into the fault state.
DC1 (or DC2) Failure Detect
Test Description :
Verify that the monitor recognizes a loss of DC power lasting more than 175ms.
Test Sequence :
1. Monitor is powered up in the quiescent state.
