• I. EIA RS -232 INTERFACES. EIA RS -232 Interface Module provides a 25 -pin female ' D -connector for data transmission—direct via a null mo- dem cable or through an external modem and over phone lines—to a computer, point-of-sale terminal or printing device. The RS -232 Interface Module with Auxilliary Port provides an additional 25 -pin female D -connector. 1. Cable Runs. An RS -232 Interface and RS -232 Interface with Auxilliary Port can be used for direct local attachment of terminals if the cable run is no more than 60 feet. In practice, runs longer than 60 feet have performed satisfactorily. However, since the RS -232 specification restricts operation to up to 50 feet, direct -connect cable runs greater than 50 feet are not warranted for proper operation. CAUTION: RS -232 CABLE RUNS LONGER THAN 50 FEET COULD RESULT IN DATA ERRORS, OR COMPONENT DAMAGE OR BOTH. 2. Peripheral Equipment Requirements. Any peripheral equipment connected to an RS -232 serial port must meet the following criteria: a. Peripheral equipment must be UL listed. b. The equipment must have an EIA standard RS -232C or RS -232D communications protocol. c. The equipment must NOT be installed over or in a • hazardous location. J. SITEFAX FAX/MODEM AND INTERNAL MODEM INTERFACES. The SiteFax Fax/Modem and the 300/1200 -baud Internal Interface Modem provide snap -in jacks for direct data transmission over phone lines. 1. For connection to telephone equipment subject to local regulations 2. Maximum short circuit current: 0 amps 3. Maximum open circuit voltage: 0 volts SECTION 5. CAPACITANCE PROBE INSTALLATION 10 WARNING: TO PROTECT YOURSELF AND OTHERS FROM BEING STRUCK BY VE- HICLES DURING WORK, BLOCK OFF YOUR WORK AREA DURING INSTALLATION AND SERVICE. WARNING: TO AVOID ELECTRICAL SHOCK WHICH COULD KILL YOU, BE SURE AC POWER TO THE TLS -350 MONITOR IS OFF DURING INSTALLATION. A. TANK DIAMETER MEASUREMENT. . Perform the following procedure to ensure that probes are installed in the proper tanks (see Figure 21, "Tank Diam- eter Measurement"). Inaccurate readings will result if probes are not the correct length for the given tank diameter. Site Preparation an Installation Instructions TLS-qPUST Monitoring System 1. Measure the distance from the bottom of the tank to the top of the probe riser pipe (a). 2. Measure the distance from the bottom of the probe riser pipe to the top of the probe riser pipe (b). 3. Subtract (b) from (a) to determine the correct tank diameter (c). 4. Make sure the probe length (Dimension "A", Figure 22 "Capacitance Probe Dimensions" is correct for the tank diameter.

Cap kits with pre -drilled holes for a standard 4" riser pipe are available from Veeder-Root. Order Kit Number 312020-952, one for each probe. If a kit has not been ordered, perform the following: WARNING: DO NOT PERFORM DRILLING AND TAPPING PROCEDURES INA HAZARD- OUS AREA. DRILLING AND TAPPING CAN CAUSE SPARKS AND IGNITE VOLATILE FUMES AND LIQUIDS FOUND IN A CLASS I, GROUP D HAZARDOUS LOCATION. FAILURE TO COMPLY COULD RESULT IN DEATH, SE- RIOUS PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE. 21
