5 Chapter 1 Introduction This chapter provides an overview of the XM-720 Machine Monitor. It also discusses the components of the monitor. For information about See page Introducing the XM-720 Machine Monitor 5 System Description 6 Using this Manual 7 The XM-720 Machine Monitor is referred to as XM-720 or monitor throughout this manual. Introducing the XM-720 Machine Monitor The XM-720 monitor is a 2-channel machine monitor designed for monitoring the condition of fans, pumps, motors, turbines, gear drives, and other machines. The XM-720 is designed to be used with accelerometers, velocity and non-contact sensors. It samples inputs, compares them to threshold values, performs self-test routines, and provides outputs to bargraph displays, relays, and LED indicator lights. There are three variations of the XM-720 Machine Monitor: Table 1.1 XM-720 Machine Monitor Catalog Number Measures Includes the following XM Modules 1440-PK02-05M0 Standard dynamic vibration XM-120 Dynamic Measurement Module XM-441 Expansion Relay Module 1440-PK02-05M1 Low frequency dynamic vibration XM-121 Low Frequency Dynamic Measurement Module XM-441 Expansion Relay Module 1440-PK02-05M2 gse vibration XM-122 gse Vibration Module XM-441 Expansion Relay Module 5

During normal operation, the machine s "vital signs" remain within relatively narrow ranges. If a mechanical problem develops, it will be reflected as a change in one or more of these vital signs. This change will be detected by the XM-720 and cause an alarm. The monitoring system consists of a number of transducers connected to the XM-720. The transducers installed on the machine convert the "vital signs" to electrical signals that are transmitted to the XM-720 monitor. The XM-720 accepts the signals from the transducers, processes and measures the signals, and closes electrical relay contacts if one of the signals increases too much. The relays can be connected to annunciators or to automatic machine controls.

Meter caption sheet Mounting template sheet Installation Guidelines Selecting a Location for the XM-720 Monitor IMPORTANT This product is an open type component and shall be installed in a suitable grounded enclosure accepted by local authority having jurisdiction. The XM-720 monitor is designed for panel mounting in a control room or local mounting in an enclosure for ready access to the front panel by operating personnel. When selecting a location for the monitor, keep in mind that it is a complex electronic device. It is designed and manufactured to withstand quite severe environmental conditions, but as with any electronic equipment, it will give the longest, trouble-free service if treated with care. The selected location should not subject the monitor to dripping water from above, or to heat from equipment installed beneath it.

11 Installing the XM-720 Machine Monitor 11 Hazardous Locations Due to the proximity of some control rooms to process machinery, the control room interior may be designated as a hazardous area within the definition of Article 500 of the (U.S.) National Electrical Code, or similar codes in other countries. If the control room is classified as a Division 2 area (N.E.C.), present interpretation of the code usually permits the operation of electrical equipment if two conditions are met during normal operation: 1. Arcing or sparking contacts must not be exposed, and 2. No surface temperature may exceed 80% of the ignition temperature (in C) of the hazardous gas or vapor. The XM-720 monitor meets the first requirement since all relay contacts are hermetically sealed. The second requirement is met if ignition temperature of the hazardous gas or vapor is above 200 C (392 F). ATTENTION See the XM Documentation and Configuration Utility CD for Hazardous Locations installation drawings. The XM Documentation and Configuration Utility CD is packaged with the XM-720. Wiring Use solid or stranded wire. All wiring should meet the following specifications: 12 to 28 AWG (0.08 to 2.5 mm 2 ) Recommended strip length 8 to 9 millimeters (0.33 inches) Mounting the XM-720 Monitor The XM-720 monitor is designed for installation in a wall, panel cutout, or custom enclosure.

Figure 2.7 Wiring Connection for Trip Relay (Non-failsafe)

19 Installing the XM-720 Machine Monitor 19 Connecting the Remote Relay Reset Signal In the provided configuration files, the XM-720 relays are configured to be latching relays. This means the relays stay activated even when the condition that caused the alarm has ended. The remote relay reset signal enables you to reset the XM-720 relays remotely after you have corrected the alarm condition. Wire the Remote Relay Reset Signal to the XM-720 back panel as shown in Figure 2.8. Figure 2.8 Remote Relay Reset Signal Connection ATTENTION The switch input power supply must be grounded at a single point. Connect the Switch Return signal to chassis or earth ground at either the XM-720 system, the switch, or other equipment that is wired to this switch. If grounding at the XM-720 system, connect a jumper between the Switch RTN terminal and any available Chassis GND terminal. Connecting the Transducers The XM-720 monitor can accept input from any Entek non-contact eddy current probe, a standard IEPE acclerometer, velocity transducer, AC voltage output or a DC voltage output measurement device.

20 20 Installing the XM-720 Machine Monitor The sensitivity, operating range, and power requirements have been predefined in the provided configuration files. The characteristics of the transducer and the signal processing performed on the input signals can be changed using the XM Serial Configuration Utility. Refer to Transducer Parameters on page 44. IMPORTANT The 1440-PK02-05M2 (gse) monitor can measure both "standard" vibration, similarly to the 1440-PK02-05M0, and g s Spike Energy (gse). It can produce the gse measurement only with an IEPE accelerometer or externally powered sensor. Setting the Buffer Range for the Transducer The XM-720 provides buffered outputs of all transducer input signals through the BNC connectors on the front panel. The voltage operating range of the buffered outputs must be configured to coincide with the corresponding transducer bias range. This operating range is configured by placing a jumper from terminal 5 (channel 1) and terminal 22 (channel 2) to terminal 6 (Positive Buffer Bias) or terminal 21 (Buffer -) on the XM-120/121/122 module, depending on the transducer. The buffered output operating range is configured independently per channel. Table 2.3 Configuring Buffered Output Operating Range Transducer Input Range Channel Connect XM-12x Terminal Negative Bias -24 to +9V Positive Bias -5 to +24V Non-Bias -5 to +9V To XM-12x Terminal

21 Installing the XM-720 Machine Monitor 21 IMPORTANT By default, both buffered outputs have been wired for a positive bias transducer (accelerometer and powered sensor). This means that orange jumper wires have been supplied on the XM-120/121/122 terminal block between terminals 5, 6, and 22 (see Figure 2.9). Figure 2.9 Jumpers for buffer input wiring Orange jumpers for buffer outputs If the transducer is not a positive bias transducer, follow these guidelines: For a non-contact sensor, remove the orange jumper between terminals 5 and 6 (terminals 22 and 6 for channel 2) and install it between terminals 5 and 21 (terminals 22 and 21 for channel 2).

32 32 Installing the XM-720 Machine Monitor Bargraph Meters The XM-720 front panel has two vertical-scale meters, one for each input channel. Each meter consists of 31 solid-state lamps (light emitting diodes) arranged one above the other. Scale markings on the window appear at 3% increments, thus there is one scale mark for each of the thirty lamps. In the provided configuration files, each meter is configured to continuously display the overall vibration level. The amplitude of the signal appears as a continuous bright light next to the one of the thirty scale marks. This simplified display makes it easy for you to recognize potential problems as the measured signal amplitude approaches one of the setpoints. The measurement displayed in the meter, the full scale, and the alarm and trip (danger) thresholds are configurable using the XM Serial Configuration Utility. Refer to Chapter 3 for more information about the XM Serial Configuration Utility. The XM-720 is shipped with clear self-adhesive caption sheet for customizing the meter scale. The caption stickers contain the most popular measured units and ranges. The caption sheet also contains orange and red arrows for labeling the alert and danger (trip) threshold levels. Follow these instructions to customize the scaled face plate. 1. Remove the front bezel. To do this, insert a blade-type screwdriver between the plastic bezel frame and front panel and lift the bezel off. 2. Remove the scaled faceplate. Be careful not to scratch the clear lens. 3.
