    Danger alarm, or a “first out” Danger alarm message from another monitor, the 6687 stores this data in a separate memory area. A “first out alarm” is the first alarm in an interconnected series of monitors. This feature allows later analysis of the data leading up to the event that caused the Danger alarm.

    Monitor Description Front Panel Description The 6687 front panel appears below. It consists of two bar graphs, showing the position of the two input channels relative to the full scale. Above the bar graph, the numeric display shows the actual value for the active input channel. The numeric display automatically switches between the two input channels every two seconds.

  • Page 16: Inputs

    Inputs The primary 6687 terminal connections are described below. For a complete listing of the inputs, see “Monitor Backplane” on page 8. Transducer input for each of the two input channels: Displacement sensor sensitivity specified in mV/mil, mV/mm, or mV/µm, adjustable in...

    Display Backlight The backlight makes it easy to see the 6687 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 6687 automatically turns on the backlight to alert you.

  • Page 18: Displaying Alternate Pages

    6687 Monitor Displaying Alternate Pages The 6687 has two display pages. The first is the one pictured on page 3, and shows the two bar graphs. To display the second page, press and release the DIS button. There are three fields in the second display page.

  • Page 19: Status Messages

    Basic Operation Status Messages The 6687 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 voltage signal goes out of the T X FAIL specified range.

  • Page 22 The 6691 power supply polarity must match the transducer. For example, if using an Entek IRD 15383, 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 23: Non-Contact Sensor To Monitor Wiring

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

    Factory menu. Note: The 6687 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 35 Under normal (nonalarm) conditions, the relay closes the circuit between the common and the N/C (normally closed) terminals. Under alarm conditions, the relay changes state to close the circuit between the common and the N/O (normally open) terminals. Entek IRD 6687 Protection Monitor...

    This section guides you through setting the display scale and zero position for the monitor. The 6687 allows you to choose the display full scale high, full scale low, and zero position for your particular application. This example assumes that the full scale low position (cold position) for the case is at 0 mils.

    To obtain the voltage at FS HI, place a spacer between the case and the plunger of the LVTD. The spacer should be the same length as the maximum change in case expansion (1000 mils for this example). Entek IRD 6687 Protection Monitor...
  • Page 39 Transducers may be simulated directly at the backplane as shown or elsewhere. If this involves application via barriers, ensure that the barrier rating is not accidentally exceeded.

  • Page 40: Calibration And System Ok Relay Test

    Increase the DC voltage input to the voltage at FS HI. Look at the 6687 front panel display, and note the digital value for channel 1. It should be the same as the FS HI setting ± 2.5% of full scale.

  • Page 41: Alarm Relay Test

    LO alarm setpoints go into alarm when the input value goes below the alarm level. Remember that the 6687 has both LO and HI alarms. You should test both sets of alarms for each channel if you are using them.
