  • Page 11: Introduction

    The monitor buffers the last 30 minutes of values (1/minute) for each channel. In the event of a Danger alarm, or a “first out” Danger alarm message from another monitor, the 6623 stores this data in a separate memory area. A “first out alarm” is the first alarm in an interconnected series of monitors.

    The accelerometer signal is typically integrated to velocity because velocity is less dependent on frequency. Velocity gives a better approximation of the energy in the vibration signal. The 6623, however, can use the input from accelerometers, vibration sensors, or non-contact displacement probes.

  • Page 13: Front Panel Description

    Monitor Description Front Panel Description The 6623 front panel appears below. It consists of one bar graph, showing the level of the input relative to the full scale. Above the bar graph, the display shows the actual vibration value for the input.

    Used when configuring the 6623: selects the highlighted menu option, accepts the displayed value for the selected configuration option. Inputs The primary 6623 inputs are described below. For a complete listing of the inputs, see “Monitor Backplane” on page 8. Transducer input on the input channel: Accelerometer sensitivity specified in mV/g, adjustable in 0.01 mV/g increments...

    Display Backlight The backlight makes it easy to see the 6623 display, even in dim light. When the system is functioning properly and no signals are in alarm, the backlight is off. However, in case of an alarm or transducer failure, the 6623 automatically turns on the backlight to alert you.

  • Page 16: Displaying Alternate Pages

    6623 Monitor Displaying Alternate Pages The 6623 has two display pages. The first is the one pictured on page 3, and shows the bar graph. To display the second page, press and release the DIS button. There are four fields in the second page.

  • Page 17: Status Messages

    Basic Operation Status Messages The 6623 can display a number of status messages that alert you to alarms or to problems with the transducers or monitoring system. This message appears when the transducer bias signal goes out of the TX FAIL specified range.

    The 6691 power supply voltage and polarity must match the transducer. For example, if using an Entek IRD 911 accelerometer, the 6691 must be configured to provide positive voltage. For more information on configuration of the power supply, refer to the manual on 6600 monitor power supplies and backplanes.

  • Page 20: Non-Icp Accelerometer To Monitor Wiring

    The 6691 power supply voltage and polarity must match the transducer. For example, if using an Entek IRD 910 accelerometer, the 6691 must be configured to provide positive voltage. For more information on configuration of the power supply, refer to the manual on 6600 monitor power supplies and backplanes.

  • Page 21: Coil-Based Velocity Sensor To Monitor Wiring

    Since the velocity sensor does not use current from the 6691 power supply, the polarity of the supply voltage on terminal 4 does not matter. You may ground the cable shield at either end of the cable. Do not ground the shield at both ends. Entek IRD 6623 Protection Monitor...

  • Page 22: Non-Contact Sensor To Monitor Wiring

    The 6691 power supply polarity and voltage must match the transducer. For example, if using an Entek IRD 1900 non-contact sensor, the 6691 must be configured to provide negative voltage. For more information on configuration of the power supply, refer to the manual on 6600 monitor power supplies and backplanes.

  • Page 23: Configuration

    Configuration Configuration This section describes how you configure the 6623. All the controls to configure a 6600 monitor are on the front panel of the monitor. There are no jumpers or DIP switches that you must set to configure the monitor. The 6623 has two levels of configuration: User menu - This menu allows you to set the date and time, set the Alert and Danger alarm setpoints, and inhibit the Danger alarm relays.
  • Page 24 If the current value does not change when you press the Arrow buttons, then the monitor is protected by the link security feature. Contact your Supervisor for assistance. For more information on the link security feature, contact Entek IRD Customer Support.

    Factory menu. Note: The 6623 maintains a minimum of 1 volt and a maximum of 24 volts difference between the TX LO and the TX HI values, so it is not possible for the TX LO value to be greater than the TX HI value.

  • Page 30: Relays Submenu

    Under normal (nonalarm with power applied to the unit) conditions, the relay closes the circuit between the common and the N/O (normally open) terminals. Under alarm or loss-of-power conditions, the relay changes state to close the circuit between the common and N/C (normally closed) terminals. Entek IRD 6623 Protection Monitor...

  • Page 32: Track Submenu

    Choose whether the monitor counts every tachometer pulse, or every EXIT eighth one. At high tachometer input speeds, the 6623 spends most of its time counting pulses and recalculating the machine RPM. NO - The monitor counts and recalculates the RPM for every tachometer pulse.

    → the Factory menu. Note: The 6623 will operate outside of the RPM MIN and RPM MAX limits, but the results are not guaranteed to be accurate. The 6623 displays the vibration value in inverse video on both display pages when the tachometer is outside the RPM limits.

  • Page 36: Testing Calibration And Relays

    When testing any of the 6600 protection monitors, you must use the correct input signal. For example, most 6623 configurations for use with an accelerometer expect a bias voltage. If the input signal does not include the expected bias voltage, the monitor signals a transducer fault.
  • Page 37 × 70.7 mVRMS/g 212.1 mVRMS The bias voltage is halfway between the TX LO and TX HI settings, so the full scale input signal should be 212.1 mVRMS with an offset of +10 VDC. Entek IRD 6623 Protection Monitor...
  • Page 38 Notes: Ensure that the oscillator frequency is within the monitor passband. On a 6623, integrating from acceleration to velocity, or velocity to displacement, both frequency and amplitude of the applied signal determine the value of the derived parameter. Always verify with counter or oscilloscope.

    20 mA ± 4.5%. Decrease the input signal amplitude to 0 (zero). 10. Look at the 6623 front panel display, and note the digital value. The digital value for channel 1 should be 0 (zero) ± 2.5% of full scale.
