4. may want to TEST the geophone and or microphone connection and setup by pressing the test button on the seismograph If anything is not properly connected the LCD will read Check followed by the channel GEO TRAN OR VERT indicate vibration channels and you may have to replant the geophone to get a level monitoring position Check Mic indicates the linear microphone is not properly connected Checking the modem The modem has four indicator lights on the front panel These lights from left to right are Network Signal Activity Power For proper operation the lights should be as follows Power the light should always be solid green when the modem has power Network the light should be solid green If the light is flashing you haven t connected to the network yet or there is a problem with the cellular signal Signal the light should be solid green or flashing rapidly A solid light indicates a very strong cellular signal The light will flash more slowly as signal decreases until the light fails to blink indicating no signal If this occurs you will need to move the entire setup to an area with better cellular signal Aiming the Solar Panel The solar panel should be aimed as to capture the position of the sun at its highest solar gain typically from 10am 2pm This will allow the panel to recharge the battery daily FINALLY MAKE SURE THE LOCKBOX IS LOCKED WITH A PAD LOCK WE CANNOT BE RESPONSIBLE FOR STOLEN EQUIPMENT
5. o ways In rock or on concrete secure the lockbox to the ground using 2 concrete anchors Set the lockbox in its final position Using the 1 2 hole tabs in the bottom of the lockbox for guides drill a 3 4 inch hole with the rock drill and bit It may be easier to use the longer bit Place the nut on the end of the bolt so you don t damage the threads when tapping the bolt into the rock or concrete The geophone may be secured to the surface using a similar procedure with 3 8 inch concrete anchors In soil secure the lockbox to the ground using 2 4 pieces of 3 foot long 1 2 or 3 8 rebar depending on the size or your TABS Instantel Minimate Plus Setup Unpack the seismograph from the carrying case Placing the Geophone If you are monitoring in soil use the supplied 3 anchor screws to attach the geophone to the ground inside the lockbox base If you have not removed the shelf inside the base you can do so at this point by removing the set screw Point the arrow on the geophone toward the vibration source and firmly secure it to the ground At this point you can place the shelf inside the base on which you will place the battery seismograph and modem Placing the Seismograph With the shelf in the base of the lockbox place the Minimate Plus on the shelf toward the air overpressure monitoring hole and go ahead and attach the geophone to the GEO port Placing the linear microphone If you are monitoring blasting connect
6. term monitoring Be aware that the modem will draw current from the battery constantly unless a timer is used Solar Panel and External Battery The power cable for the seismograph should be connected directly to the solar panel power leads upstream from the charge controller The external battery is configured using the charge controller and or timer The solar panel power leads are attached to the solar controller which is then connected to the battery The power cable for the modem should be connected directly to battery for short term monitoring or to the timer for long term monitoring Power System Components Solar Panel 10 Watt Module Small solar panels are difficult to find online Matheson Mining Consultants stocks 10 watt solar panels only as these are what we use in the Western United States to maintain batteries You may need to obtain a larger solar panel depending on your monitoring location as the 10 watt panel may not adequately recharge your batteries To determine what type of solar insolation is in your area the following tool may be used http www wholesalesolar com Information SolarFolder SunHoursUSMap html External Battery Sealed Lead Acid Battery 35 amp hour 86 99 and 20 amp hour 82 99 batteries are available from Batteries Plus http www batteriesplus com Or you can order similar batteries online from a battery wholesaler such as batterywholesale com http www batterywholesale com Charge
7. the linear microphone to the MIC port and push the end of the microphone through the hole in the base so that the microphone is just sticking outside the lockbox base If you are not monitoring blasting there is no need to attach or use the linear microphone Refer to the Minimate Plus user manual on how to disable the microphone when not in use Power System The Lockbox can be used in three different power configurations Solar Panel only Battery backup only or Solar and Battery backup Matheson Mining Consultants recommends using a small charge controller with the battery backup system and for longer monitoring periods a timer should be used to maintain backup battery integrity over the life of the project Solar Panel Only In this configuration the 10 watt solar panel supplies DC power 18 22V directly to the seismograph The seismograph contains a voltage regulator that prevents the internal seismograph battery from being overcharged An additional backup battery is not needed in this configuration A modem is not used in this configuration External Battery Only This setup is typically not used because the external battery is used to power the modem and is not a backup for the seismograph except in special cases The solar panel power leads are attached to the solar controller which is then connected to the battery The power cable for the modem should be connected directly to battery for short term monitoring or to the timer for long
8. troller Remove the battery from the box it was shipped in and place the battery on the shelf next to the seismograph Open the charge controller and connect terminals rings or forks to the red and black wires on the charge controller so you can connect these wires to your battery terminals Connect the power cables from the solar panel to the battery The white cable connects to the positive terminal of the battery which may be red and the black cable connects to the negative terminal of the battery which will be black Make sure the connections are tight Placing the modem Make sure you have a heavy duty plastic bag in which to store the modem it will not function if gets wet Connect the antenna cable protruding from the underside of the lockbox LID to the antenna connection on the modem Connect the serial cable from the modem to the AUX port on the Minimate Plus Connect the power cable to the modem coming from the battery or timer and seal the modem inside the plastic bag so that it cannot get wet in any way The power light on the modem should come on indicating the modem has power Power the seismograph Connect the power cable directly to the solar panel leads using 2 wirenuts The red charge light should illuminate on the seismograph If the red light does not illuminate you most likely have the polarity reversed Checking the seismograph With everything connected you can now start the monitoring on the seismograph You
