4. Observe:
The plant voltage increases to the set voltage
Power Minor alarm (PMN) is generated
RECT and MIN LEDs are illuminated
5. Using the Float Settings Menu Screens, select Set Point.
6. Use the Arrows, and UP/DOWN keys to change the system float
voltage setpoint to it’s original value. Press ENTER to save.
7. Observe:
The plant voltage decreases to the original set voltage
Power Minor alarm (PMN) retires
RECT and MIN LEDs are extinguished
High Float Voltage Alarm – Systems with Actual Loads
Step Action for Testing the High Float Voltage Alarm
NOTE: Clear all controller alarms for this test.
NOTE: The System Voltage WILL NOT change.
NOTE: The high float voltage alarm test is completed by changing the
threshold for this condition below the system voltage to make it
active.
1. Using the Float Settings Menu Screens, select Set Point and note the
value. ________
2. Using the Voltage Alarms Menu Screens, note the High Float Alarm
threshold value. _________
3. Use the Arrows, and UP/DOWN keys to change the High Float Alarm
Threshold to 0.1V below the System Voltage. Press ENTER to save.
4. Observe:
Power Minor alarm (PMN) is generated
RECT and MIN LEDs are illuminated
5. Using the Voltage Alarms Menu Screens, change the High Float Alarm
threshold value to it’s original value. Press ENTER to save.
6. Observe:
Power Minor alarm (PMN) retires
RECT and MIN LEDs are extinguished
High Voltage Shutdown – New Installations Only
STEP Action for Testing High Voltage Shutdown Alarm
NOTE: The High Voltage Shutdown Test is recommended only for new
installations where a dummy load is available prior to the application of
office load, and batteries are connected.
NOTE: There are three requirements for a serial rectifier to shut down upon a
controller initiated High Voltage Alarm.
