SymCom Motor Saver RM-2000-RTDW Manuals

The RM-2000-RTDW motor-monitoring device can be used to monitor and/or control SymCom’s Model 777 via an RS-485 Modbus network. Two form C output relays are available for an RTD alarm and a warning alarm. Alarm and trip levels can be set for each RTD to activate the RTD alarm and deactivate the 777 output relay respectively. In addition, the RM-2000-RTDW has two inputs: one to connect to a ground-fault module and the other for connection to a remote reset button. A second communication port allows monitoring and control of up to 99 RM-2000-RTDW devices from a computer with SymCom’s Solutions software, or a PLC, DCS, or SCADA system. The RM-2000-RTDW is environmentally protected and can easily be mounted on the front of a panel or MCC. The RM-2000-RTDW displays the following motor information: • Real-time line currents, average current and current unbalance • Current to ground • Line-to-line voltages, average voltage and voltage unbalance • Instantaneous power • Power factor • Last four faults • All programmed 777 settings • Remaining restart delay times • 8 RTD temperatures • Warning settings The RM-2000-RTDW is also equipped with a real-time clock, which allows access to the following motor management information: • Total motor run-time (reset capable) • Time and date of last four faults, with voltage and current at time of trip • Time and date of last ten motor starts • Total number of motor restarts (reset capable) • Minimum time between any two starts with time and date • Run-time since last start (reset capable) • KWhs consumed • KVARs consumed RM-2000-RTDW Remote Monitor User’s Guide Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: [email protected] 4 PART I ± INSTALLATION AND OPERATION FEATURES The RM-2000-RTDW is a motor management device used in conjunction with any SymCom Model 777. The RM-2000-RTDW provides the following features: Information Displayed · Run-Time Information: the RM-2000-RTDW can display all of the information the Model 777 displays as well as information that the Model 777 maintains but does not display, such as current unbalance, voltage unbalance and power factor; see page 1 for a complete list of viewable parameters. · Real time clock: the RM-2000-RTDW has a real time clock so it can track time-dependent data such as power draw (KW), energy consumption (KWH), and run-hours. · Detailed information about fault conditions: the RM-2000-RTDW can store information about power conditions just before the Model 777 tripped in addition to the date and time of the fault. · Historical data: the RM-2000-RTDW can display historical data about the motor being monitored by the Model 777 such as the total number of starts, the number of trips, and the date and time of the last 10 starts. Installation · Panel mounting: a model 777 is often mounted inside a motor control panel and its display is not visible. The RM-2000-RTDW can be mounted on the outside of the panel which allows all of the information from the Model 777 to be displayed. · Remote mounting: the RM-2000-RTDW communicates with the Model 777 by an RS485 cable which can be up to 4000 feet long. This allows the RM-2000- RTDW to remotely monitor a Model 777. · Ease of installation: the RM-2000-RTDW only requires drilling 4 mounting holes and punching out two 2” OD round holes using a standard knock out punch or drilling 1 15/16” – 2 3/16” holes for the terminals to protrude through to the inside of the panel.

Attach the template drawing to the panel where the RM-2000-RTDW is to be mounted. 2. Take caution when drilling the holes to mount the RM-2000-RTDW. Use an 11/64” drill bit for the four corner mounting screws. Drill a 1 15/16” – 2 3/16” hole for the terminals to protrude through to the inside of the panel. 3. Verify the gasket is in place on the back of the RM-2000-RTDW. Attach the RM-2000- RTDW to the panel using the four screws provided. 4. Run the appropriate wires to the back of the RM-2000-RTDW and terminate the wires in the provided screw-type, depluggable connectors; see the wiring diagram on the following page. This should include at least 120VAC control power, one set of communication wires to the 777, and ground wire to case ground on the panel. NOTE: When connecting a Benshaw remote RTD module, terminal A of the RTD module must be connected to B1 of the RM-2000—B must be connected to A1. 5. It is important to have the A phase of the breaker connected to L1 on the 777, B phase to L2 and C to L3. Equally important, is to have the A phase conductor through the A phase hole, B through the B phase hole, and C through the C phase hole of the 777. 6. The 777, when used with the RM-2000-RTDW, should be connected according the following wiring diagram.
