Y Locating a Leak When the system goes into alarm, the following steps should be followed: 1. Remove the terminating resistor from the last monitoring station and connect it to the end of the monitor cable running to the first monitoring station. This will reset the alarm lamp and sonalert. If not, follow all the procedures in the section titled, "TROUBLE-SHOOTING." 2. Reconnect the monitor cable to the Sensor Cable. Disconnect the other plug in the first monitoring station. Attach the terminating plug to the end of the Sensor Cables. Check monitor to see if alarm is still on. If alarm is still activated, then the first monitoring station is con- taminated with product. if first monitoring station is contaminated, check the rest of the system by connecting the Monitor Cable to the Connector Cable in the first well (by-passing the first Sensor Cable). Put the terminating plug back in the last monitoring station. If alarm is still on then there is more than one monitoring station contaminated with product. To check out the rest of the monitoring stations, take the terminating plug from the last monitoring station and check out each monitoring station by disconnecting plugs and plugging the terminating plug into the system. Starting at the monitoring station closest to the monitor and working away from the monitor. It is important to remember that the function of the monitor is to read the terminating plug. If the cable between the monitor and the terminating plug is cut or shorted out, then the signal be- tween the two ends is interrupted causing an alarm. 3. If the first monitoring station is not contaminated (alarm stops when the terminating plug is at- tached to the first length of Sensor Cable), reconnect all plugs and repeat the same procedure at the second monitoring station. This is done until a contaminated monitoring station is located, then Step 2 is done. 4. To verify a monitoring station is at fault, remove the cable and check for damage due to ex- posure to petroleum product. Note: For Radial Cables, tie a piece of nylon cord to the end of the cable so when the cable is pulled out, the cord is pulled in for later fishing in of new cable. Reinstating the System For Double Wall Tanks After the leaking tank or tanks have been located and repaired, the TC-3000 Monitoring System can be reinstated. 1. First, remove all traces of petroleum from between the two walls. This can be done by pumping in water and detergent to breakdown the petroleum product, This procedure should be done several times to ensure complete removal of all product. 2. When the tank or probe is clean, a new sensor cable can be installed into the tank. 3. A replacement cable can be obtained from your local distributor. Trouble Shouting If, when the monitor is connected to the main power, the red lamp comes on and stays on, check the following: 1. All cables are installed and all plugs have been connected. 2. The 100K ohm terminating resistor plug has been installed at the end of the cable. 3. Make sure Monitor Cable is connected per wiring diagram on Monitor cover. 4, If above checks out call Total Containment, Inc. for further instructions. —13—
