8 System description The TN3801 system is designed for measuring the level of all types of liquid products in a batch of tanks onboard all kind of vessels, ballast tanks, service tanks as well as drafts. The principle is based on the generation of a continuous air or gas-flow bubbling through a pipe running till the bottom of the tank. The pressure of this flow is measured as the hydrostatic pressure due to the liquid column in the tank. This measurement is transmitted by digital redundant lines towards a monitoring system. The TN3801 system includes a main unit, its several options, bubbling pipes,... The main unit gathers the electronic and pneumatic components in a wall-mounted cabinet, made of steel with epoxy painting. The optional processing / display unit questions successively the digital transmitters of the main unit, receives the measurements from the 4-20 ma analog transmitters (if optional module is present) and displays the processed data. The optional 48 analog inputs module collects the 4-20 ma signals from other analog transmitters. The optional 4-20 ma output modules copies the output of a relevant channel as 4-20 ma signal. General synopsis The general synopsis of the system is shown on the previous page. Main unit The main unit is located above the main deck in safe and protected area, such as the control room. This unit hosts : Up to 24 pneumatic bubbling flow modulators, one per channel, each with two manual valves for bubbling fluid supply shut off and bubbling line purge, Up to 3 electronic board including 8 pressure sensors each (2100 or 4000 mbar models), and one microprocessor carrying out the data processing, the digital conversion and the management of two RS422 / RS485 digital communication lines, for redundancy according to Modbus or EMS protocols, One optional 4-20 ma output module per channel A filter-pressure reducer unit for air or neutral gas supply of the pneumatic modulators is located inside this main unit. The pneumatic inlet and outlets are fitted with quick-release couplings. TN3801 Technical Manual 8

10 Processing / display unit (optional) This unit can be installed on the cabinet door, or in remote box. The TN3801 processing / display unit performs the following functions: collection of the measurements from the transmitters, scaling and processing each transmitter measurements, communication and data validity control, monitoring a "System Fault" alarm sequence, with buzzer and dry contact outputs, final data display on a LCD screen, final data control by two alarm limits per channel monitoring a "data alarm" sequence, data transmission on one serial link toward a monitoring system. The communication uses the MODBUS RTU protocol. The front panel includes: a LCD screen for data and alarms display, status lamps, a keypad menu for function selection, a numeric keypad for configuration and maintenance parameters key in. The use of the keypads is intuitive and does not require a specific training. The large LCD screen increases the data availability and the man-machine interface is simplified for easy access to functions and configuration using scrolling menus.

It collects the measurements coming from the local analog 4-20 ma transmitters (level measurements, pressure temperature measurements, inclinometers and else). These measurements are transmitted by the same line than the electro pneumatic system board(s) ma analog inputs board Module for 4-20 ma output per channel (optional) This option is achieved by addition close to each pneumatic modulator, of a conditioner board for 4-20 ma output. It includes a pressure sensor connected on the pressure output of the pneumatic modulator ma analog output board, for each channel TN3801 Technical Manual 11

Go to following or previous transmitter, or enter a new value for the current tank. After key-in of the last transmitter value, pushing [ENTER] allows to return to the main menu. Back to the main menu ALARM menu The ALARM menu allows to enter two alarm limits per transmitter listed on the current page and for each possible associated measurements. The limit types are classified by code: 0 = no alarm whatever the limit values, 1 = two high alarm limits (alarm HH/pre-alarm H) ; normal situation below the two limits, 2 = one high alarm and one low alarm (H/L) ; normal situation between the two limits, 3 = two low alarm limits (pre-alarm L/ alarm LL) ; normal situation above the two limits. Push ALRM to access to the sub-menu and activate the message and the key-in lines. The message line shows the name of the transmitter concerning the key-in line (automatically, the first of the list). According to the current page, the key-in line indicates the type of measurement concerned (level, temperature, pressure, and angle). TN3801 Technical Manual 20

Tank name : X Level LL [0 to mm]=xxxxx Enter the value for the lowest alarm. Tank name : X Level L[0 to mm]=xxxxx Enter the value for the least low alarm. Data alarms The alarm limits are applied to the corresponding transmitter. The following transmitter is displayed. Continue the method or go back to the main menu (in the case of the last transmitter). A data alarm starts when a measurement coming from the transmitters exceeds the configured limits. Data alarm typical sequence: The screen backlight lights on, The buzzer is activated in continuous mode, if set enabled, The page number concerned by the alarm appears on the message line, The value out of limits flashes on the relevant page, The relay is activated. Example of display Data in alarm, flashing Page numbers of the value in alarm TN3801 Technical Manual 23

24 Procedure of a data alarm acknowledgement: Go to the concerned page in order to look at the measurement out of limit flashing. Push ACK (acknowledgement key). The buzzer, if set enabled, passes from the continuous mode to the discontinuous mode (during 2 seconds each 15 seconds), except if another unacknowledged data alarm is present. In this case, it is necessary to acknowledge all the measurements out of limits, one by one. Search and solve the problem relative to the alarm condition. The alarm indication disappears as soon as the cause disappears, depending if the alarm is duly acknowledged. System alarms A monitoring is performed by the system in order to search for intrinsic failures. In the event of default, it starts a system alarm. System alarm typical sequence: The screen backlight lights on, The buzzer is activated in continuous mode, if set enabled, The LED "System fault" lights on, The page number concerned by the alarm appears on the message line, Display of a message alternating with the last valid value on the line of the relevant transmitter, The relay is activated. Procedure of a system alarm acknowledgement: Go to the concerned page in order to read the message on the line of the relevant transmitter. Push ACK (acknowledgement key). The buzzer, if set enabled, passes from the continuous mode to the discontinuous mode (during 2 seconds each 15 seconds), except if another unacknowledged system alarm is present. In this case, it is necessary to acknowledge all the system faults, one by one. Search and solve the problem relative to the alarm condition. When the problem is solved, the alarm condition disappears if this alarm were acknowledged (except if the acknowledgement were disabled during the installation). Communication fault A fault appears when the communication between the processing / display unit and the TN3801 electro pneumatic system is broken. The message "Communication fault" is displayed on the relevant page. Validity fault of the analog measurements A measurement validity fault appears when the signal delivered by the transmitter goes out the nominal rating. The message "Fail" is displayed on the relevant transmitter line. TN3801 Technical Manual 24
