115-230V AC power-supply type PM. The green / yellow wire between the back-casing and removable terminal-block may never be removed. Intrinsically Safe applications: follow the instructions as mentioned in Chapter 5 and consult “Fluidwell F0..-..-XI - Documentation for Intrinsic Safety”. DISPOSAL ...
Page 5 INTRODUCTION 1.1. SYSTEM DESCRIPTION OF THE F073-T Functions and features The level monitor model F073-T is a microprocessor driven instrument designed to display level, percentage or the height as well as the monitoring of the level for high / low values. This product has been designed with a focus on: ...
Page 6 OPERATIONAL 2.1. GENERAL The F073-T may only be operated by personnel who are authorized and trained by the operator of the facility. All instructions in this manual are to be observed. Take careful notice of the " Safety rules, instructions and precautionary measures " in the front of this manual.
Page 7 2.3. OPERATOR INFORMATION AND FUNCTIONS In general, the F073-T will always act at Operator level. The information displayed is dependent upon the SETUP-settings. The signal generated by the connected sensor is measured by the F073-T in the background, whichever screen refresh rate setting is chosen. After pressing a key, the display will be updated quickly during a 30 second period, after which the update frequency will slow-down again.
Page 8 2.4. OPERATOR ALARMS Level alarm When the actual level is outside the allowed range, an alarm message will be displayed indicating the type of alarm: LO LEVEL, HI LEVEL. The alarm is terminated automatically as soon as the level is within its range again. ...
Page 9 CONFIGURATION 3.1. INTRODUCTION This and the following chapters are exclusively meant for electricians and non-operators. In these, an extensive description of all software settings and hardware connections are provided. Mounting, electrical installation, start-up and maintenance of the instrument may only be carried out by trained personnel authorized by the operator of the facility.

Page 10 Matrix structure SETUP-level: SCROLLING THROUGH SETUP-LEVEL Selection of function-group and function: SETUP is divided into several function groups and functions. Each function has a unique number, which is displayed below the word at the bottom of the SETUP display.
Page 11
Page 11 To change or select a value: To change a value, use to select the digits and to increase that value. If the new value is invalid, the increase sign or decrease-sign will be displayed while you are programming.
Page 13 3.2.3. EXPLANATION OF SETUP-FUNCTIONS 1 - LEVEL 11 determines the measurement unit for the displayed level MEASUREMENT UNIT SETUP (volume) and alarm values. The following units can be selected: L - m3 - kg - lb. - GAL - USGAL - bbl - _ (no unit). Alteration of the measurement unit will have consequences for operator and SETUP-level values.
Page 14 2 - HEIGHT If desired the height of the level column can be calculated and displayed. 21 determines the measurement unit for height. MEASUREMENT UNIT SETUP The following units can be selected: mm - cm - m - mtr - inch - ft - mmwk - mmwc - cmwk – cmwc - mwk - mwc - inwc - ftwc - mbar - bar - psi - no unit.
Page 15 4 - DISPLAY The small 8mm digits can be set to display: UNDER height - percentage - off This function determines if the level alarm values can be set at both SET ALARM Operator level and SETUP-level or SETUP-level only. If SETUP has been selected, the alarm values are still visible for the Operator but cannot be changed.
Page 16 6 - SENSOR The resistive signal of a sensor mirrors the actual level. This signal is FILTER measured several times a second by the F073-T. The value measured is a "snap-shot" of the real level as it will be fluctuating. With the help of this digital filter a stable and accurate reading can be obtained while the filter level can be set to a desired value.
Page 17 6 - SENSOR (CONTINUED) With this setting it is possible to calibrate the input value for 100% as the CALIBR. HIGH / 100% signal from the sensor might not reflect it’s reference value at maximum level. This function will measure the provided resistance value at maximum level.
Page 18 INSTALLATION 4.1. GENERAL DIRECTIONS Mounting, electrical installation, start-up and maintenance of this instrument may only be carried out by trained personnel authorized by the operator of the facility. Personnel must read and understand this Operating Manual before carrying out its instructions. ...
Page 21 4.4. INSTALLING THE HARDWARE 4.4.1. INTRODUCTION Electro static discharge does inflict irreparable damage to electronics! Before installing or opening the unit, the installer has to discharge himself by touching a well-grounded object. This unit must be installed in accordance with the EMC guidelines (Electro Magnetic Compatibility).
Page 22 4.4.2. TERMINAL CONNECTORS WITH POWER SUPPLY - TYPE : PB / PD / PX For Intrinsically Safe applications: read chapter 5. The following terminal connectors are available: ALARM SENSOR SIGNAL POWER SUPPLY POWER SUPPLY RESISTANCE INPUT UNIT OUTPUT BACKLIGHT TYPE: T TYPE: PX...
Page 23 Terminal 5-6: POWER SUPPLY UNIT - type PX: To power the unit an internal battery can be used (type PB) and / or an external DC power supply of 8-30V DC (type PX). Connect the "-" to terminal 5 and the "+" to terminal 6. When power is applied to these terminals, the optional internal battery will be disabled / enabled automatically to extend the battery life time.
Safety Instructions Certificates, safety values, control drawing and declaration of compliance can be found in the document named: “Fluidwell F0..-T-XI - Documentation for Intrinsic Safety”. For installation under ATEX directive: this intrinsically safe device must be installed in accordance with the Atex directive 94/9/EC and the product certificate KEMA 05ATEX1168 X.
