• • Printer Interface Module. Required for interface between the CPU board and integral printer. • Remote Display Interface Module. Required for interface to a Veeder-Root Remote Display. • Remote Printer Interface Module. Provides a 25 - pin male D -connector for data transmission to a remote serial printer. • SiteFax Fax/Modem Module. A 2400 -baud inter- nal modem and a 9600 -baud facsimile with twin snap -in j acks for direct data transmission over phone lines. B. PROBES. The TLS -350 can accommodate Veeder-Root capacitance and magnetostrictive probes. The installation and wiring procedures for these probes are described in this manual. C. SENSORS. A TLS -350 system can incorporate sensors that detect liquids in interstitial spaces of double-wall tanks and piping sumps of double-wall piping, detect hydrocarbon liquids and vapors in monitoring wells, and detect liquids and hydrocarbons in dispenser pans and containment sumps. Interstitial, piping sump and hydrostatic sensors are two - wire devices; while vapor and groundwater sensors, and containment sump and the dispenser pan sensors are three -wire devices. The installation and wiring proce- dures for these sensors are described in this manual. D. LINE LEAK DETECTORS. The TLS -350 system can include up to eight line leak detectors monitoring one line per detector, and each detector requires one Line Leak Detector Module in- stalled in the monitor. Site preparation and installation instructions for the Veeder-Root Line Leak Detector are contained in Manual Number 576013-764. E. REMOTE DISPLAY. The TLS -350 system can interface to a Veeder-Root Re- mote Display. Site preparation and installation instruc- tions for the Remote Display are contained in Manual Number 576013-811. SECTION 3. SITE PREPARATION JN WARNING: IN INSTALLATION OF THIS PRODUCT, COMPLY WITH THE NATIONAL ELECTRICAL CODE; FEDERAL, STATE AND LOCAL CODES; AND OTHER APPLICABLE SAFETY CODES. Ift WARNING: TO PROTECT YOURSELF AND if OTHERS FROM BEING STRUCK BY VE- HICLES DURING WORK, BLOCK OFF YOUR WORK AREA DURING INSTALLATION OR SERVICE. FAILURE TO COMPLY WITH THESE WARN- INGS COULD RESULT IN DEATH, SERIOUS PERSONAL INJURY, PROPERTY LOSS, AND EQUIPMENT DAMAGE. Site Preparation anji&stallation InstructionsT TLS-31WST Monitoring System This section does not contain site preparation instructions for a line leak detector. Since much of the site preparation for a line leak detector will be performed concurrently with the site preparation for the rest of the system, be sure to consider its requirements at all times. If installing line leak detectors with this system, be sure to refer to Manual Number 576013-764 for site prepara- tion and installation instructions. A. PROBE RISER PIPE INSTALLATION. (See Figure 4, "Capacitance Probe Installation Require- ments," and Figure 5, "Magnetostrictive Probe Installa- tion Requirements.") IMPORTANT: For maximum height -to -volume accuracy, select the threaded hole closest to the middle of the tank and install a 4 -inch riser pipe (ANSI pipe, sch. 40). Standard procedures for installing a fill pipe can be used. Instructions are based on a 4 -inch riser pipe, however, the capacitance probes will also fit a 3 -inch riser. 1. If the tank is buried, excavate the portion of the tank that contains the riser hole. 2. Remove the bung from the hole and install the riser pipe. NOTE: The top of the riser pipe must be threaded to accept a 4 x 8 NPT cap adaptor ring. Figure 4.
