3 Enwatch Unit 3 Enwatch Unit Overview The following sections give an overview of the hardware and electrical components of the Enwatch unit. Hardware Overview The Enwatch unit contains a printed circuit board and power supply on a mounting base plate and housed in a metal enclosure. Use the key on the door of the enclosure to access the enclosure. The unit is pre-wired with mains input terminals connected to an internal 24V power supply. The power supply and internal wiring are fitted to a mounting base. The output of the 24V power supply connects to the printed circuit board. The circuit board is mounted on six stand-offs to the mounting base plate. The printed circuit board and terminal connectors are packed separately. To correctly install the unit, follow the steps in Install the Enwatch Unit on page 6.

4 4 Enwatch Unit Electrical Overview Enwatch is a distributed network system providing 16 channels of analog inputs together with 4 trigger channels. The unit includes signal conditioning and analog to digital conversion. It lets you connect 16 two-wire ICP or other sensors into your Emonitor Online system. Each Enwatch unit is a microprocessor-based system, complete with a network controller that carries out data acquisition tasks as directed by an Emonitor unload station. A typical diagram for an Enwatch unit is shown in Figure 1. Figure 1 - Enwatch Block Diagram The Enwatch unit responds to all relevant network data exchanges as defined by the Ethernet protocol using the UDP/IP standard. In addition, there is a comprehensive on-board monitor program that can exercise all functions via the on-board serial RS232 port.

5 Enwatch Unit 5 The circuit board is a completely self-contained, 16-channel analog input to Ethernet interface, including power regulation and local communication facilities. Each block of the diagram in Figure 1 on page 4 is described below. Table 1 - Electrical Block Descriptions Block ICP interface Multiplexer Description Each of the 16 channels has its own ICP interface that is capable of powering a typical two-wire ICP transducer. The nominal voltage is 24 V with a constant current of 3.6 ma. A typical transducer has a bias voltage value of around 11 V, so that the system can accommodate a full ±10V input range. The ICP interface can be disabled for AC and DC coupling of voltage signals. The multiplexer circuit selects one of the 16 input channels under software control. All inputs are over-voltage and ESD protected. High-pass filters Four software-programmable high-pass filters (0.36 Hz, 2.67 Hz, 5.3 Hz, and 23.8 Hz) are available to remove unwanted low frequency signals. Integrator Spike Energy function (gse ) Anti-aliasing filter Analog-to-digital converter (ADC) Clock generator Gain amplifier Microprocessor subsystem Watchdog Ethernet controller/buffer memory/10base-t Power regulation An on-board hardware integrator is available for getting a velocity measurement from an accelerometer, as well as displacement from a velocity sensor. The host software can perform a second level of integration if required. gse provides a conditioned signal suitable for measurement of bearing condition. This filter removes high-frequency components from the incoming analog signal that can alias back into the sampled signal, resulting in incorrect data in the spectrum. The filter has a very high roll-off and removes all alias effects in standard sampling/spectral analysis applications. The ADC samples up to 51.2 khz and has 16-bit resolution, providing a theoretical dynamic range of 96 db. The timer varies the sampling rate under microprocessor control. Sampling can be synchronized to one of 4 external triggers (typically a once-per-rev TTL signal from a rotating shaft). This system can also take a preprogrammed number of samples per revolution. The external trigger acts as a tachometer to determine shaft speed. Pre and post-trigger functions are available. The Enwatch unit automatically sets the input gain in auto-range mode as each channel is selected by the multiplexer. This contains the microprocessor, flash memory, and SRAM memory. The microprocessor controls the Enwatch unit under instructions stored in the flash memory. The SRAM memory acts as a temporary data storage area if buffering is required before data is transferred over the network. The microprocessor subsystem incorporates a watchdog that, if a power glitch or other external effect interrupts the system, automatically resets without the need for user intervention. These functions control data transfer over the Ethernet network. The system uses the UDP/IP standard protocol and implements 10 Base-T as the physical network layer. Input DC power is derived from an AC to DC converter and the Power Regulation function provides the secondary DC voltages as required.

20 20 Enwatch Unit Setting Up Sample Measurements This section gives examples of setting up measurement definitions in the Emonitor software. DC or Other Numeric Measurements Suppose you have a transducer with an output of -2 V to 2 V and a linear scale from -10 F to 100 F. How do you set up the transducer in the Emonitor software? If the volts reading is R, then the data stored in the Emonitor software is: (R / calibration + DC offset) Input range volts: (X, Y) Scale value: (A, B) volts Data in the Emonitor software = (R - X) x ((B-A) / (Y-X)) + A Calibration value in transducer setup: [(Y-X) x 1000mv / eu]/(b-a) DC Offset in transducer setup: A - (B-A) x X / (Y-X) EXAMPLE Input range: (-1.31 V, V) Scale value: (100 F, 200 F) Calibration: [( (-1.31)) x 1000] / ( ) = 21.8 Offset: ( ) x (-1.31) / (0.87-(-1.31)) = Input type should be DC coupled and the jumper setting on board needs to be set as DC couple as well. 1. In the Emonitor software, select Setup>Calibration and set up the calibration for the Temperature transducer.

21 Enwatch Unit Select Setup>Transducer to select the Temperature transducer in the collection specification. 3. In the Emonitor software, define a numeric measurement definition with the temperature units and the Temperature collection specification. Transducer Bias Reading The Enwatch board can take transducer bias readings; however, this is not a transducer check function that detects transducer failure before taking data. The bias reading is an independent reading with a different signal path on the Enwatch board. 1. In the Emonitor software, select Setup>Transducer. 2. To define a new transducer name (for example, Transducer Check ) click New. 3. Enter a name and click OK.

22 22 Enwatch Unit 4. Select Setup>Calibration to select Bias Voltage as the input type for this transducer. Set the calibration to 1000 and the offset to Click OK. 6. Select Setup>Collection to define a new collection specification. Select Transducer Check as the transducer. 7. In the Emonitor software, define a numeric measurement definition with V DC units and the Transducer Bias collection specification. Magnitude And Phase Reading A magnitude/phase reading is similar to any other data collector in the Emonitor software. Use the Mag & Phase collection specification to set up an overall measurement. Then select 1st Order as the measurement filter (or any other desired order).

23 Enwatch Unit 23 Order Normalized Measurements Enable order normalized measurements in the collection specification. 1. In the Emonitor software, select Setup>Collection. 2. Edit an existing collection specification or create a new one. 3. Verify that Order normalization is checked. The Enwatch unit then finds the machine speed and applies it to the number of orders to select the proper sampling rate before collecting data. IMPORTANT You must also define a trigger channel for the Enwatch channel so that the Enwatch unit can find the machine speed.

24 24 Enwatch Unit DSP Functions in the Enwatch Driver The Enwatch unit takes only time domain data and returns that data to the host software. All DSP functions are done by the host driver. In this way, the firmware can focus on data collection speed. Because the Enwatch board does not handle calculating the average time waveform, the host driver software must tell the Enwatch unit to collect a time waveform of sufficient length to calculate the average. Limitation on the Number of Points in the Enwatch Unit The Enwatch unit has 640 K bytes memory for data storage. If you attempt to collect data on more points than can fit in memory, the unit returns an error message. The message appears in the Unload Station Manager window (refer to the Online Applications Guide for more on the Unload Station Manager). The Enwatch driver can combine measurements in some cases (see Combining measurements in the Enwatch driver on page 17). If a route has 5 points per channel and 400 lines, 4 averages, no overlap averaging: Bytes required: 5 points x 16 channels x 1024 bin x 2 byte/bin x 4 averages = bytes If a route has 2 points per channel and 800 lines, 4 averages, no overlap averaging: Bytes required: 2 points x 16 channels x 2048 bin x 2 byte/bin x 4 averages = bytes To best use the 640K memory, try to use overlap averaging. For examples, see Maximum number of averages that can be supported on page 19.

25 Enwatch Unit 25 Configure and Enwatch Board with Emonitor Software The Enwatch unit is specially designed to operate over an Ethernet connection. Each Enwatch unit has a unique IP address that can be changed through the RS232 port inside the unit. Ideally, one Enwatch unload station can serve an unlimited number of Enwatch units. However, to improve unload speed, multiple Enwatch unload stations are suggested. Each Enwatch unit has 16 vibration channels and 4 tachometer channels. In addition, the Allen Bradley Enlive software (live mode analysis) can be used to lock onto one channel at a time. During live mode analysis, regularly scheduled unload continues to unload whatever data is in the Enwatch unit buffers before entering live mode analysis. The Enlive software has a default timeout of 30 minutes to prevent an extended break in unloading scheduled data. For more information on setting up an Enwatch unit in an Emonitor system, refer to the Emonitor User's Guide, publication EMONTR-UM001.

28 28 Enwatch Unit 2. Select the Channel tab. This tab is used to map the Enwatch channel to the measurement point in the database. 3. On the Channel tab, double-click the first square to the left of the channel number. A connection to the database opens and the hierarchy tree from the Emonitor database is displayed. 4. Expand the tree and select the measurement point to which you want to map the Enwatch channel and click OK. The machine name and location are populated. All measurement points associated with the machine name are collected by the Enwatch board. 5. Click Finish.

29 Enwatch Unit 29 The Enwatch unit appears under the Enwatch Unload Station. Save the Machine Speed with a Spectrum To add or edit an Enwatch unit, click the Trigger Channel tab. The Timeout is defined in seconds (the default is 5 seconds). The Number of pulse per rev default is 1 pulse per revolution. Click the Channel tab and assign the correct Trigger channel to the vibration channel. This example uses trigger channel 1 for the measurement on input channel 1. When the Enwatch unit collects data for channel 1, the unit checks trigger channel 1 to get the machine speed reading. The speed reading comes back with time waveform data and gets stored into the database with the vibration data.

30 30 Enwatch Unit Validating Enwatch Measurements To add or edit an Enwatch unit, you can set up a validation function to allow the driver to check the channel s data before updating the database. This function can be used to filter unwanted data when the machine is not running, or when some other parameter is not within the correct bounds. Click the Channel tab, then double-click in the Validate column to set up the validation parameters. You can reference any channel in any order.
