FCC NOTICE FCC ID: ZOC-IMI670A01 This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
Introduction The Echo® Wireless Vibration Sensor is a one-way wireless transmitter used for the condition monitoring of plant equipment. The sensor, when activated by a magnet, will “wake up” at determined intervals (8 hours by default) to measure and transmit vibration levels. An Echo® Receiver connected to a computer with the Echo® Data Server software installed is required to receive and collect transmissions.
The Magnet Switch and LED Status Indicator The Echo® Wireless Vibration Sensor is activated by a magnet switch located on the side of the housing. The exact location of the magnet is etched on the sensor housing. If a fairly strong magnet is held near the location of the magnet switch, the blue LED light will begin blinking quickly. If the sensor was previously deactivated it will become active and immediately take its first measurement.
Programming the Echo® Wireless Sensor The Echo® Wireless Vibration Sensor can be programmed with a computer running the Echo® Data Server software through a serial port. Tip If your computer is not equipped with a serial port, a USB to RS232 adaptor can be used. These are readily available from computer electronics vendors. Attaching the Programming Cable To begin programming the Echo® Wireless Vibration Sensor, unscrew the cap carefully to expose the USB port inside the sensor.
The program will then ask if you wish to set up a Echo® Wireless Sensor or an EchoPlus® Wireless Junction Box. Select “I want to add, update, or view an Echo® Wireless Sensor’s Parameters”. Select the receiver that you would like this specific sensor attuned to. If you are using a single receiver select the default setting. The software will then ask if you would like to set up the sensor, the database, or both. If this is the first time you are activating this sensor you must do both.
The connection window will appear. Select the appropriate COM port to which the cable is connected. Reading the Current Programmed Parameters Click “Link to Echo®” and the green light will illuminate indicating the connection has been made. The fields at the right of the window will populate with the current programmed parameters. Tip The Sensor ID is set at the factory and CANNOT be changed. This ID is unique to each sensor we manufacture.
Explanation of Echo® Wireless Sensor Parameters Sensor ID – The Sensor ID is a unique ID programmed and etched onto each sensor at the factory. This number cannot be changed. Transmission Interval – The Transmission Interval is the time between transmissions. The factory default level is 8 hours, that is the sensor will “wake up” and make a measurement every 8 hours (3 times per day). At the default 8 hour transmission interval the primary lithium-ion batteries are expected to last 5 to 10 years.
Updating the Database to Match Sensor Programming If this is the first time you are putting the sensor in the database the following dialog will appear. This dialog will indicate the standard template has been assigned to this sensor. If this is the case, refer to the Echo® System Manual for instructions on setting up the database. When a sensor programming has been changed the database will automatically update to match the current programming.
Changing the Transmission Interval, RVL, or CF Report Threshold manually in the Database is NOT recommended. These values determine what the software expects the sensor to do, not what the sensor will Tip actually do. For example, if you change the Database from 8 hours to 1 hour, the sensor will still transmit every 8 hours, but the Database will expect transmissions every 1 hour. The software will think the transmitter is late or missing transmissions.
The RV (Raw Vibration) Option Sensors ordered with the RV prefix including the optional raw vibration output feature. These sensors are easily distinguished due to the small connector located on the side of the unit. This connector is not present on the standard unit. A special cable can be used to connect to the sensor’s 4 pin connector and a standard BNC connector on your data collector. To collect data, treat the sensor like a standard ICP® or IEPE 100 mV/g accelerometer.
Mounting The Echo® Wireless Vibration Sensor should be stud mounted on a clean, flat surface. The sensor is sensitive in the axis that passes through the mounting hole in the base of the unit. It is not recommended to mount the sensor with a magnet or adhesive due to the size and mass of the sensor. Outline Drawing Spot Face Tool If a clean and flat spot is not available, it is recommended to prepare a flat machined surface with IMI model 080A127 1” spot face tool.
Replacing the Battery Pack To replace the battery pack, carefully slide the battery pack out and disconnect the small power connector on the circuit board. DO NOT ATTEMPT TO RECHARGE BATTERIES. DO NOT REPLACE WITH STANDARD AA SIZE BATTERIES. The Echo® Sensor is equipped with primary lithium-ion batteries that Caution are not rechargeable. Please consult the factory or your local distributor for replacement battery packs.
