PowerLogicTM Series 800 Power Meter Chapter 6—Alarms 63230-500-225A2 3/2011 Chapter 6—Alarms This section describes the alarm features on all Series 800 Power Meters. For information about advanced alarm features, go to “Advanced Alarms” on page 53. Basic Alarms The power meter can detect over 50 alarm conditions, including over or under conditions, digital input changes, phase unbalance conditions, and more. It also maintains a counter for each alarm to keep track of the total number of occurrences.
PAGE 52
PowerLogicTM Series 800 Power Meter Chapter 6—Alarms 63230-500-225A2 3/2011 Setpoint-driven Alarms Many of the alarm conditions require that you define setpoints. This includes all alarms for over, under, and phase unbalance alarm conditions. Other alarm conditions such as digital input transitions and phase reversals do not require setpoints.
PAGE 53
PowerLogicTM Series 800 Power Meter Chapter 6—Alarms 63230-500-225A2 3/2011 Priorities Each alarm also has a priority level. Use the priorities to distinguish between events that require immediate action and those that do not require action. • • • • High priority—if a high priority alarm occurs, the display informs you in two ways: the LED backlight on the display flashes until you acknowledge the alarm and the alarm icon blinks while the alarm is active.
PAGE 54
PowerLogicTM Series 800 Power Meter Chapter 6—Alarms 63230-500-225A2 3/2011 Under-voltage: Pickup and dropout setpoints are entered in volts. The per-phase undervoltage alarm occurs when the per-phase voltage is equal to or below the pickup setpoint long enough to satisfy the specified pickup delay (in seconds). The under-voltage alarm clears when the phase voltage remains above the dropout setpoint for the specified dropout delay period. Over-voltage: Pickup and dropout setpoints are entered in volts.
PAGE 55
PowerLogicTM Series 800 Power Meter Chapter 6—Alarms 63230-500-225A2 3/2011 Scale Factors A scale factor is the multiplier expressed as a power of 10. For example, a multiplier of 10 is represented as a scale factor of 1, since 101=10; a multiplier of 100 is represented as a scale factor of 2, since 102=100. This allows you to make larger values fit into the register. Normally, you do not need to change scale factors.
