Page 5 INTRODUCTION SYSTEM DESCRIPTION OF THE F490-A-PL Functions and features The multi purpose indicator model F490-A-PL is a loop powered microprocessor driven instrument, designed to display process information from a 4-20mA signal, like pressure, temperature, percentage etc. This product has been designed with a focus on: •...
Page 6 OPERATIONAL GENERAL • The F490-A-PL 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 For the Operator, the following functions are available (if activated): • Display value and measuring unit This is the main display information of the F490-A-PL. After selecting any other information, it will always return to this main display automatically. •...
Page 8 CONFIGURATION 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 9 Use the control panel to navigate through SETUP-level PROG-key When a function is selected, this key is used to start the programming sequence. SELECT-key This key is used to select the next function in the list (e.g. 1 → 1.1 → 1.2 → 1). When the top of the list is reached, it will wrap around and return to the function group selection.
Page 10 3.2.4 RETURNING TO OPERATOR-LEVEL When all settings are configured correctly, the unit can be returned to OPERATE-level. Please keep a record of all settings for later reference. Use the control panel to return to OPERATE-level PROG-key In order to return to the operator level, press the PROG-key for three seconds. When no keys are pressed for 2 minutes, SETUP-level will be left automatically.

Page 12 3.3.2 EXPLANATION OF SETUP-MENU 2: SENSOR 2 SENSOR FORMULA The F490-A-PL can process the 4-20mA signal in two ways: ▪ V = S x I Interpolation - the signal is processed linear: √ ▪ V = S Square root - for differential pressure: where: V = Value: the calculated value S = Span: the value at maximum signal (Span).
Page 13 TUNE MAX / With this setting it is possible to calibrate the input value for 20mA as the 20MA signal from the sensor might not be exact 20.0 mA at maximum signal. ▪ Warning: be very sure that the offered signal is correct before the calibration is executed as this function has major influences on the accuracy of the system! After pressing PROG, three settings can be selected:...

Page 15 HANDLING THE F-SERIES ENCLOSURE 4.3.1 IDENTIFICATION For Intrinsically Safe applications: Installation and identification labels are shown in chapter 5. Identification label To identify your F4-Series device, all field mount enclosures have a weatherproof identification label placed on the outside of the unit. Fig.
Page 16 4.3.2 OPENING / REMOVING THE COVER To open the F-Series enclosure, the front cover needs to be removed. Please follow this procedure: 1. If necessary, clean the enclosure with an anti-static cloth made damp with a mild soap solution. Wait for the enclosure to dry before opening.
Page 17 MECHANICAL INSTALLATION DIMENSIONS – ALUMINUM AND STAINLESS STEEL ENCLOSURES 4.4.1 • → When ordering stainless steel enclosures, the code “H_” turns to “HS_”, e.g. HA HSA). • Aluminum enclosures are available with a 15 mm, 0.6” deeper rear cover (code turns to HB_). 75 mm (2.95") 112 mm (4.40") 130 mm (5.12")
Page 19 4.4.3 MOUNTING • When installed in an aluminum enclosure and a potentially explosive atmosphere requiring apparatus of equipment protection level Ga and Da, the unit must be installed such that, even in the event of rare incidents, an ignition source due to impact or friction sparks between the enclosure and iron/steel is excluded.
Page 20 4.5. ELECTRICAL INSTALLATION • Electrostatic discharge (ESD) does inflict irreparable damage to electronics! Before installing or opening the F490-A-PL, the installer has to discharge himself by touching a well-grounded object. • For reasons of ESD and safety, always ground the metal enclosure properly as indicated. It is the responsibility of the installer to install, connect and test the Protective Earth connections in accordance with the (inter)national Rules and Regulations.
Page 21 4.5.3 FIELD WIRING CONNECTIONS • Do ground the aluminum enclosure properly as indicated in paragraph 4.5.2. It is the responsibility of the installer to install, connect and test the ground connections in accordance with the local and (inter)national Rules and Regulations. •...
Page 22 4.6.3 TERMINAL 4-5: 4-20MA SIGNAL INPUT AND POWER SUPPLY - TYPE PL The F490-A-PL requires a 4-20mA signal that will be processed 4 times. With Type PL, the unit will be powered from the 4-20mA input signal. The input circuit is isolated from the backlight circuit on terminals 9 and 10. With the use of the signal links between terminal 2 and 3 and between terminal 6 and 7, it is possible to easily connect the signal wires and cable screens of two separate cables.
