1. ADIA EOPHYSICAL DIAS CL Current Lockout System USER s MANUAL 7 O We highly recommend that the DIAS CL technology be integrated into a field safety system that addresses all aspects of the dangers of working with electrical equipment The DIAS CL technology is designed to be nested with a standard power ON power OFF protocol using conventional radio communication In this way the DIAS CL system provides an added layer of protection for the crew against electrocution and there will be less risk of injury as crews transition from the old transmitter protocols to the new system involving the DIAS CL technology 1 3 Interface and Indicators DIAS CL Controller The DIAS CL controller is a small rugged self contained device that can be easily and quickly deployed with minimal training The external features of the DIAS CL controller are shown in the following image of the top surface of the handheld Figure 1 DIAS CL interface layout Status Screen Screen to display the status of the system System Status the status of all units is given on the left hand side up to 10 units can be displayed The status of each is indicated as follows e S safe indicates that the user is safe to be working with the wires e C clear indicates that the user is clear of the wires and current transmission can proceed e O offline indicates that the user is offline and may not be clear this status may be d2. as both a reference and a teaching tool and it is recommended that you read the entire document If you experience operational problems with your system please call technical support at 1 306 249 4422 1 1 Unpacking Your System Thank you for purchasing a DIAS CL system A packing list is included with your shipment that identifies all of the items that are in your order You should check your shipment against the packing list upon receipt of your shipment If you find that an item is missing or was damaged during the shipment please call Dias immediately so that we can correct the problem Following is a list of items that are included with your shipment e DIAS CL current lockout units complete with internal battery e Lanyards for each DIAS CL handheld e DIAS CM L current monitor equipped with DIAS CL lockout technology 1 2 General Description The DIAS CL is a lightweight portable technology that is designed to mitigate the risk of electrocution from the high voltage wires and electrical equipment during the course of geophysical surveying Many ground geophysical surveys involve the transmission of current at high voltage through wires that extend through the survey area and through ground electrodes Direct current resistivity and chargeability DCRC surveys often involve the laying of extensive amounts of conductive wire through the survey area Current is transmitted through this wire repeatedly through a production survey day and be
