Battery switch

Battery switch is used to turn on and off the battery, if not in OFF state, in order to prolong the battery life. This switch is only used for battery control. When external power input is used, the switch is placed in a OFF state, only to disconnect the battery power supply. If the external power supply is still on, the seismograph will not be turned off. If the instrument is turned off, the external power supply should be disconnected and the switch will be placed in a OFF state.

Functional keys

The following are the functions of each key:

 UP     move the cursor into the next position, into the next menu, data. (Long continuous)

 DOWN   move the cursor into the next position, into the next menu, data -. (Long as continuous -)

 SET    switch between function menu and normal display, enter function menu from submenu, press reset alarm.

 ESC    return to the next menu and power up into normal test mode (3 minutes without operation automatically into normal test   mode).

OLED is the most direct form of feedback. The screen displays the date (year/month/day) on the upper left and status information such as System Normal,TROUBLE, or Alarm below the time (24 hours) on the upper right

OLED display has no angle limit and low power consumption. In any environment can be displayed normally, not limited by temperature. 

  Relay output port

There are two connectors on the left side of the operation panel (10 stitches). There are 3 relays, each using 3 contacts. The 2-side relay is a self-locking relay. One ALARM mode output, the other is TROUBLE mode output. If triggered, they won't change even if the power is off. RELAY CONTATCT RESET key is used to reset. The intermediate non-locking relay is also output in ALARM mode and automatically reset when exiting ALARM mode.

 Each relay has 3 output terminals, COM、NO、NC. (see wiring diagram)

Relay reset key

The key is used to reset the self-locking relay. Pressing any key will not affect the display or turn off the alarm sound. Press ALARM、TROUBLE key to reset all self-locking relays. Press the ALARM or TROUBLE to hear the crisp contact action sound if the relay is already in action without affecting the system. 

Remote ALARM reset input port

  Connect the switch to the port for remote reset of earthquake alarm. For example, in the control room, press the switch to turn on the alarm without local reset, easy to operate. Connect a local switch to a local ALARM RELAY CONTATCT RESET. External switch :100 Ma@12VDC.

Installation

1. Install the box body on the load-bearing wall or connected support with a screw or shaft pin. Can be installed in one of the axes (X,Y,Z) in a horizontal or vertical direction, the position self-detection program will automatically detect its position to make it horizontal. Note: do not install on easily sloshing objects to avoid the probability of misoperation.

2. Connect the control board to the relay output port, note that each relay has 3 output terminals.

     "TROUBLE" the output terminal is activated, it indicates that there is a problem with the seismograph system and requires on-site inspection. It must be connected to the sound alarm or display alarm device in the control room or cabinet. "ALARM" is the alarm output relay action. where the self-locking relay will remain until the reset key is pressed. Another non-self-locking relay operates automatically when there is an alarm and reset automatically when the alarm condition does not exist. It should be noted that the self-locking relay may be an action state or a reset state before boot. When the power is connected, press the reset key to make it reset, and the relay will respond again  Function execution (all self-reset relays, no self-locking function).

 Initialization check.CALIBRATE）

The sensor of the seismometer has been set to the best state before leaving the factory. This initialization check function can only be aimed at a few position angle differences that may occur during installation. And only the local seismometer fixed in a certain position after the initialization check.

When you need to initialize the check, use the UP key to move the cursor to "2. CALIBRATE" option, and then press the SET key to determine. LCD will show:

 It is important that the seismograph can not be moved or vibrated throughout the calibration process. After the check is completed, the LCD will return to the normal operation interface.

 Measurement (select submenu 3. Metering)

The measurement function is used to measure any external force acceleration other than gravity acceleration. these forces are decomposed into (XYZ) axial acceleration shown separately. The following legend illustrates the relationship between direction and coordinate axis. A vertical axis belt has a "^" sign. For the following columns, the Z axis is vertical.

The measurement function has two display modes. First one shows the acceleration in each coordinate direction (unit G); the other shows the inclination on each coordinate axis. Press the UP key for 1 second and the measurement function enters acceleration measurement mode. Press the DOWN key for 1 second and will enter angle measurement mode.

in the acceleration measurement mode, each force is described as the value of an absolute g- force (1.00 G i.e., the unit of gravity acceleration). Accurate G.0.01 If the initialization check is done when boot, each axis must now be displayed as 0.00 without any external force (Z axis is 1.00).

In the angle measurement mode, the system automatically calculates the deviation between the 3D angle of the current seismograph and the angle data after the previous initialization check. Unit for degree, accuracy 1 degree.

Alarm Trigger Value Settings4.Alarm Setting）

 This function is used to set a trigger value for the local earthquake system to enter the alarm. Here are two ways to set the ASCE25-97 standard:

ASCE 25-97 standard provides seismic waves with a certain frequency range and the corresponding maximum and minimum acceleration threshold for determining whether an earthquake alarm is issued. Check A appendix for more information about this standard. Because of the high accuracy of the sensor, the system can divide the alarm part of the standard into 10 secondary levels.

This level is compiled into 01 to 10,01 is the most sensitive level ,10 is the lowest sensitivity. The default value of 06, at the middle level, is suitable for most situations. Use the UP key to change the ASCE level, press the ESC key to save the settings and return to the main function menu.

   Early warning detection time5. Suspected Time）

Used to adjust the detection and reset time of early warning. Adjustment S.5-30

Earthquake alarm confirmation time*(select submenu 6. Earthquake Time)

Used to adjust the detection and reset time of earthquake alarm. Adjustment S.20-100

Early warning level (select submenu 7. Warning)

This feature is used to set the trigger level of the alert. There are 12 levels (01-12) to choose from. Level 01 is the most sensitive level and level 12 is the least sensitive level

Function Description of Relay

1.ALARM self-locking relay: when the acceleration value of the X、Y、Z shaft is greater than the alarm setting level (ASCE-LEVEL), the alarm output is carried out immediately, the self-locking relay action is ALARM, the screen, buzzer and indicator lamp are also prompted to operate accordingly, and the self-reset relay is reset at the same time. The relay can only be manually reset and remotely reset.

2.ALARM self-reset relay: when the acceleration value of the X、Y、Z axis is greater than the warning setting level (WARNING-LEVEL), the relay enters the early warning preparation stage. if the acceleration value of the X、Y、Z axis reaches the warning value again within 15 seconds, the relay continues to, and the screen, buzzer and indicator light also prompt the operation accordingly. After the vibration disappears, the delay setting time system automatically reset the screen, buzzer and indicator light into the suspected warning state. If the acceleration value of the X、Y、Z axis does not reach the warning value again during the suspected warning time, the system exits the warning state after  Electronic reset.

 3.TROUBLE self-locking relay: when the sensor fails, damage or external power down after the relay action suction and make the corresponding prompt interface, the relay can only manually operate reset, not remote reset.

Alarm Mode Flow Chart

Detection of suspected early warning

 When the sensor detects the vibration, the display changes to the perceived state of the suspected warning, self reset relay action,

 When the vibration stops, if the alarm is not triggered enough, the display will change to normal state, self-reset relay reset.

 Then turn to normal detection mode.

 Alert

As the acceleration of the vibration exceeds the preset value, the system enters the ALARM detection state. When the vibration is strong enough to meet the alarm conditions, the system will activate the response relay, buzzer issued a continuous alarm sound

When the vibration ends, the system holds all the recorded data

 A non-automatic lock ALARM relay is automatically reset and the alarm sound is converted to intermittent sound. Alarm will flash on the display.

Press the ALARM RELAY CONTACT RESET key or close the REMOTE ALARM RESET input terminal to reset the self-locking ALARM relay contact.

 Failure

when the system found an error during self-checking, TROUBLE flashed on the screen, the fault relay triggered, and the table below lists the possible causes of the failure.

    When the fault is relieved, the liquid crystal will automatically clear the fault display. in any case, the fault self-locking relay is reset only by pressing the TROUBLE RELAY CONTACT RESET key. Reset power is not working.
