AlarmsAn alarm is a binary (On/Off) flag that is activated when auser-defined condition is true. The status of an alarm canbe viewed on the LCD display or through communications,including ProView NXG software. Alarms can onlybe configured via communications. See documentMN225015EN CL-7 Regulator Control ProView NXGSoftware Programming Guide for information on configuringalarms.The user can define the priority of an alarm to cause theAlarm LED, Warning LED, or no LED to be illuminated. Theassigned priority of the alarm also determines the order inwhich the alarms are viewed via the display.●● Assigning a Priority of 0–50 will cause the Alarm LEDto be illuminated when the alarm condition is active.●● Assigning a Priority of 51–100 will cause the Warning LEDto be illuminated when the alarm condition is active.●● Assigning a Priority of 101–127 will not cause an LED tobe illuminated, but the condition can be viewed on theLCD display or through communications while the alarmcondition is active.A timer can also be set for each alarm. This will allow thealarm to become active only after the alarm condition hasexisted and the period of time specified by the timer (inseconds) has expired. When an alarm becomes active,it is given the state of Unacknowledged. If the alarm isconfigured to illuminate an LED, the LED will flash aslong as the alarm is Unacknowledged. To acknowledgean alarm the Operate security level is required. Afterentering the security code, enter Alarms > AlarmsActive Unacknowledged using the front-panel menu; theunacknowledged alarms will display. Press the ENTER keyto display (ACKNOWLEDGE) and ENTER again to completethe operation. If the alarm is configured to illuminate anLED and it has been acknowledged, the LED will be oncontinuously. The alarm will turn off whenever the alarmcondition is no longer true.The control can also record an event or take a profilesnapshot whenever an alarm becomes active or inactive.The control contains two types of user-configurable alarms:Status Alarms and Data Alarms.The Status Alarm type is activated based upon thecondition of a binary (On/Off) parameter. By default, StatusAlarms become active when the parameter is On. Thealarm, however, can be inverted so that it becomes activewhen the parameter is Off. See document MN225015ENCL-7 Regulator Control ProView NXG Software ProgrammingGuide for a complete list and definitions of available Statusalarms.EXAMPLE:Configuring a Supervisory Active Alarm to be inverted witha Priority of 25 will cause the Alarm LED to flash wheneverthe Supervisory Switch is in the Off position.The Data Alarm type is activated based upon thecondition of an analog (numeric) parameter being aboveor below a threshold value. The operations countersand metering values are available as Data Alarms. Seedocument MN225015EN CL-7 Regulator Control ProViewNXG Software Programming Guide for a complete list anddefinitions of available Status alarms.EXAMPLE: Configuring a Compensated Voltage Low Alarmwith a Threshold of 115 V with a Priority of 75 will cause theWarning LED to flash whenever the compensated voltage isbelow 115 V.Sequence of events (SOE)An event is a time-stamped record of an alarm conditionor control activity. The CL-7 control is designed to recorda sequence of these events; event data is stored in non-volatile memory on the control. The last fifty events can beviewed via the front panel display using the top level nestedmenu item SEQUENCE OF EVENTS. The last 300+ eventscan be viewed using ProView NXG software.Configuring SOE can only be done using software. Thereare a number of events that are pre-configured on everycontrol. See document MN225015EN CL-7 RegulatorControl ProView NXG Software Programming Guide for alist of available events and information on configuring SOEfunctionality.Data profilerThe Data Profiler records the current state of parameterschosen by the user at regular intervals into non-volatilememory. The Data Profiler data can only be viewed usingProView NXG software. Configuring the Data Profilermust also be accomplished using the software. The usercan choose to profile as many of the instantaneous anddemand (present) parameters as desired. The samplinginterval can be set from one (1) minute to one (1) day.The storage capacity for data is limited; the greater thenumber of parameters chosen and the shorter the samplinginterval, the less overall time will pass before the recordbegins to be overwritten. In the software, a Trend Time willbe displayed as the Profiler is configured which will be anestimate of the length of time data can be recorded beforethe oldest data is overwritten.See document MN225015EN CL-7 Regulator ControlProView NXG Software Programming Guide for a list anddescription of available Data Profiler items and informationon configuring Data Profiler functionality.152INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS MN225003EN April 2018CL-7 Voltage Regulator Control
