ALARM RELAY WIRING. The TLS -250i has two pro- <br />grammable alarm relays. Terminals (l, 2, 3 and 4) are <br />provided on the power supply strip to connect these relays to <br />external alarm systems or devices. (See Figure S, "External <br />Alarm and External Input Wiring Diagram.") Any or all of the <br />TLS -250i alarm indicators can be programmed to trigger one <br />or both alarm relays (see TIS -250i Operating Manual, "Alarm <br />Relay Configuration," for programming instructions). <br />1. To utilize Alarm Relay # 1, connect the external device to <br />terminals 1 and 2 on the power supply strip in accordance <br />with Figure 8, "External Alarm and External Input Wiring <br />Diagram," and with instructions furnished with external <br />device. <br />2. To utilize Alarm Relay #2, connect the external device to <br />terminals 3 and 4 on the power supply strip in accordance <br />with Figure 8,'External Alarm and External Input Wiring <br />Diagram," and with instructions furnished with external <br />device. <br />DO NOT CONNECT ALARM RELAYS TO A DEVICE THAT <br />DRAWS MORE THAN 2Al <br />Note: Output power: Alarm relay contact, resistive load — <br />116VAC, 2A max.; or 240 VAC, 2A max.; or 24 VDC, 2A <br />max. <br />WA -1 KING: ALARM RELAYS CANNOT BE USED FOR <br />FLOW CON'L'R.OL. ALARM RELAYS PROVIDE ONLY <br />A MOMENTARY CLOSURE AND CANNOT ACTUATE <br />FLOW CONTROL DEVICES SUCH AS VALVES AND <br />PUMP MOTOR RELAYS. <br />F. EXTERNAL INPUT WIRING. The TLS -260i can accept a <br />dry -contact switch closure input from an external device <br />such as a line leak monitor or monitoring well. <br />0, <br />CUSTOMER -SUPPLIED 02 <br />DAY CONTACT 03 <br />d <br />EXTERNALINPUT I 0 S <br />SHIELDED CABLE 1 <br />a <br />! <br />07 COMMON <br />08 PRINT <br />0 p TRANSMIT <br />N <br />U110"', <br />AVX• RECEIVE <br />REC61vE <br />eg <br />25 V MAX.25 mA M <br />ALARM RELAY f 2 A2 <br />ALARM RELAY 2 I 2 A <br />9ARRiER GND.

Connect a shielded cable consisting of two IS AiVG <br />conductors between terminals 4 and16 on the TB -1 of the <br />main board and the customer -supplied dry cosicact switch <br />(see Figure 8). <br />2. Ground the cable shield to terminal 6 on the TB- I of the <br />main board. <br />Note: The cable shield should be grounded ONLY at ter- <br />minal 6 on the T13•1 of the main board — NOT AT <br />THE SWITCH END! <br />G. EIA RS -232 INTERFACE. The EIA' R5-232 interface is <br />designed to connect to modems for transmission of data over <br />telephone lines. It can be used for directlocal attachment of <br />terminals ifthe run is no more than 50 feet. In practice, cable <br />runs longer than 50 feet have performed satisfactorily: <br />however, since the RS -232 specification requires operation <br />up to 50 feet, direct connect cable runs greater than 50 fret <br />are not warranteed for proper operation. <br />WARNING: RS -232 CABLE RUNS LONGER TkL-%N 50' <br />COULD RESULT IN DATA ERRORS OR COMPO- <br />NENT DAMAGE OR BOTH. <br />H. PERIPHERAL EQUIPMENT RE491RE,MENTS. Any <br />peripheral equipment connected to the! RS -23`_ serial port <br />must meet the following criteria: <br />Peripheral equipment must be UL listed. <br />2. The equipment must have an EIA standard RS -2320 or <br />RS•232D communications protocol. <br />3. The equipment must NOT be installed over a hazardous <br />location. <br />SECTION 4. PROBE INSTALLATION <br />A. TANK DIAMETER MEASUREMENT (Figure S). Per, <br />form the following procedure to ensure that probes are <br />installed in the proper tanks. Inaccurate readings wi:l result <br />if probes are not the correct length for the given tank. <br />diameter. <br />WARNING: TO PROTECT YOURSELF AND OTHERS <br />FROM BEING STRUCK BY VEHICLES DURING <br />WORK, BLOCK OFF YOUR WORK AREA DURING <br />INSTALLATION AND SERVICE. <br />I. Measure the distance from the bottom of the tank to the <br />top of probe riser pipe (a). <br />2. Measure the distance from the bottom ofthe probe riser <br />pipe to the top of the probe riser pipe,(b). <br />3. Subtract b from a to determine the correct tank diameter <br />(c). <br />4. Make sure the probe length (Dimension "A Figure 10) is <br />correct for the tank diameter. <br />5. Using a dip stick, measure fuel height at the probe riser <br />and at a fill riser near one end of the tank. This,nforrnatiun <br />will be necessary during TLS system start up to determine <br />tank tilt. <br />6.
