Alarm/Relay Functions Circuit monitors can detect over 100 alarm situations, including over/under conditions, status input changes, and phase unbalance conditions. Each alarm condition can be set to automatically operate one or more circuit monitor relays. Multiple alarms can be assigned to each relay. Up to three form-C, 10 A mechanical relays and one solid-state output are available. Protective Functions A circuit monitor equipped with an I/O module can perform certain motor protective functions. These include phase loss, phase reversal, under voltage, and more. Once the circuit monitor detects the abnormal condition, the output relay switches within 1–3 seconds. Each protective function can operate one or more form-C, 10 ampere relays. Each relay can be activated by multiple protective functions. These functions are password protected. On-Board Alarm/Event Logging When an alarm occurs, the circuit monitor can log the event type, date and time, and the most extreme reading during the pickup delay. When the alarm condition drops out, the dropout date/time and the most extreme reading during the entire event is logged. The size of the event log can be user configured. Data Logging Circuit monitors are available with nonvolatile memory for storing meter read- ings. A user can configure the size and structure of up to 14 independent data logs to record metered data at intervals from 1 minute to 24 hours. Data logs can be used to record at regular intervals or report by exception. Each data log can record up to 100 electrical parameters (including date and time). The number of stored readings for each of the parameters is based on the amount of memory available in the circuit monitor. Models CM-2150 and up are available with up to 1.1 megabytes of extended memory. Downloadable Firmware The circuit monitor is designed to take advantage of technological advances. As Square D introduces more powerful versions of each circuit monitor, upgrade kits allow the user to install the new capabilities without changing wiring or hardware. This is possible because the circuit monitor has System Highlights PC in Plant PC in Maintenance PC in Accounting Engineers Office Department Department • Supports multiple PCs Power for power quality for load monitoring for cost allocation System Manager • Powerful software analysis Monitoring solutions 3000 Remote PC off site Software • Easily retrofit Software • Programmable controller support Ethernet, Communications • Fiber-optic, radio, and Local Area Network modem communications • Ethernet connectivity • Building automation • PowerLogic Circuit Monitors • Programmable Controllers system compatible Power Power Monitoring, • Other Intelligent Devices • PowerLogic Power Meters ® ® • MicroLogic Molded Case Circuit Breakers • 2 and 4-Wire Modbus RTU Devices Monitoring Protection, and ® • PowerLink AS Panels • Altivar Drives and Control Control Devices • Momentum I/O • Digital Relay Devices in a typical • Digitrip 810D Trip Units • Model 98 Transformer POWERLOGIC Temperature Controller system. downloadable firmware. The new firmware is transmitted from a PC into the circuit monitor, using the front optical communications port or the rear RS-485 port. The equipment containing the monitor does not have to be de-energized. This allows you to keep your circuit monitors up to date with the latest en- hancements, minimizing fear of obsolescence. Sag/Swell Detection The circuit monitor can continuously monitor for sags and swells on any metered voltage or current. This feature can help detect and analyze trouble- some voltage disturbances that can cause costly equipment down time. The circuit monitor detects sags and swells based on user-defined setpoints and delays (in cycles). When the circuit monitor detects a voltage or current disturbance, it performs an event capture to record the disturbance. This capture is configurable for 12, 24, 36, 48, or 60 cycles at 64 samples per cycle. It is performed using the patented waveform capture sampling technique that samples all current and voltage signals simultaneously. The user selects the number of pre-event cycles, ranging from 2 to 10 cycles. Thus, the event capture shows the circuit both before and after the disturbance. The event can be date and time stamped to the millisecond, and recorded in the event log. This event lasted only a quarter of a second, yet its effect shut down a production Waveform Capture process for four hours. Square D power quality experts showed that the event should not have caused an interruption to the plant, exposing a coordination problem on the Square D pioneered and patented the concept of electric utility distribution circuit. “waveform capture,” to sample, record, and display current and voltage signals. The captured wave- forms are stored in the circuit monitor memory for retrieval and display by POWERLOGIC application software. The waveform captures are used for harmonic analysis and event recording. High rd resolution waveform captures for 63 harmonic analysis at 128 samples per cycle are triggered via the network from a PC. These can be up to 30 cycles in duration. Waveform captures for event recording can be triggered by internal alarm conditions or from external signals, such as an overcurrent relay. These 64 samples per cycle event recordings can be up to 60 cycles in dura- tion. Programming Capabilities The CM-2450 Circuit Monitor is programmed using simple math functions, timers, and compare state- ments to customize data logging, control functions, and more. Application program examples include tracking disturbances onto CBEMA curves, time-of- use metering, and IEEE 519 compliance. Meter values can be analyzed in the circuit monitor and summarized in daily, weekly, and monthly reports. POWERLOGIC software can show all phase voltage and current waveforms simulta- neously, or a frequency spectrum containing harmonics through the 63rd. Mounting Options In addition to the standard flush mounting, several other mounting options are available. For applications requiring an indoor general purpose surface mounted (NEMA 1) enclosure, a 3090 SMA-220 is used. The circuit monitor mounts through the door of the enclosure, providing easy access to the rear of the monitor. The enclosure is deep enough to accommodate options, including I/O modules and voltage power modules. For applications where depth in the equipment enclosure is critical, POWERLOGIC provides the 3090 CMA-100 and 3090 CMA-110 adapters. The CMA-100 reduces the depth requirements by extending the circuit monitor beyond the front of the equipment. The CMA-110 allows the voltage/power module and some I/O modules to be mounted off of the back of the circuit monitor. Control Power Options In addition to CT and PT inputs, the circuit monitor requires control power. The circuit monitor accepts a wide range of voltages, including 120/240 Vac nominal or 125/250 Vdc nominal. When the system voltage is 480 Y/277 V, an optional 3090 VPM-277-C1 Voltage/Power Module can be used. This add-on The 3090 SMA-220 (left) and the 3090 CMA-100 provide module eliminates the need for PTs and provides control power. The optional convenient alternatives to flush panel mounting. 3090 CPM 48 Control Power Module is used when 18–60 Vdc is available. A 3090 RTM-317 Ride Through Module is also available which provides backup control power for up to 8 seconds, depending on the presence of I/O modules. These modules can be conveniently mounted on the back of a circuit monitor or on a nearby flat surface. To complete the offering, Square D manufactures a complete line of control power transformers. Field Installable I/O Modules Field installable input/output modules provide maximum flexibility, while keeping the costs for an application at a minimum. An I/O module can be easily installed on the back of the circuit monitor. Seven different I/O modules An I/O module and either a voltage/ are available. The modules provide various combinations of digital and analog power module, or a control power I/O, ranging from 1 digital input and 1 digital output to 4 digital inputs, 4 digital module can mount on the back of outputs, 4 analog inputs, and 4 analog outputs. the circuit monitor. Two inputs and one output perform special functions. Status input S1 can be configured to accept a demand synch pulse from a utility demand meter. Status input S2 is a high-speed input; it can be connected to an external relay to trigger the circuit monitor’s event capture. The KYZ solid-state output is ideal for pulse initiator applications. The form C, 10 amp mechanical relay outputs are extremely flexible—each can be configured for remote (external) or circuit monitor (internal) control. In addition, each output can be configured for normal, latched, timed, or one of six different pulse initiator modes. The analog inputs are field convertible from 0–5 Vdc to 4–20 mA. Optical Communications Interface The circuit monitor has an optical communications port built into the front panel as a standard feature. Using this port, a portable computer with an optical communications interface (OCI-2000) can retrieve data from the circuit monitor. The OCI-2000 mounts magnetically to the circuit monitor and provides a standard RS-232 interface. This interface can be used by engi- neers and maintenance personnel to retrieve captured waveforms, event and data logs, and other information without connecting to the network. It's easy to tap into a circuit monitor using a PC and an optical communications interface. 11 POWERLOGIC Circuit Monitor ➀ Circuit Monitor Dimensions Typical Wiring Diagram CTs (5 Amp Secondaries) 9.14 5.09 AŞ 232 129 4.58 .56 BŞ 116 14 Line Load .83 CŞ 3.15 21 80 N Kilo VDS Mega o AMMETER (A) [CT Primary] 3-PHASE o VOLTMETER, L-L (V) [PT Primary] A (A-B) PHASE o VOLTMETER, L-N (V) [Sys.
