1 INTRODUCTION

1.1 SYSTEM DESCRIPTION

Functions and features

The level monitor model F170-A is a microprocessor driven instrument designed to display and

monitor level and percentage. It can generate up to four alarms and output analog signal related to

the level.

This product has been designed with a focus on:

▪ ultra-low power consumption to allow long-life battery powered applications (type PB/PC)

▪ intrinsic safety for use in hazardous applications (type XI)

▪ several mounting possibilities with aluminum or GRP enclosures for harsh industrial

surroundings

▪ ability to process all types of sensor signals

▪ transmitting possibilities with analog and communication outputs.

Sensor input

This manual describes the unit with a (0)4-20mA input from the level sensor.

One sensor with a (0)4-20mA signal output can be connected to the F170-A. To power the sensor,

several options are available.

Standard outputs

▪ Max. four configurable alarm outputs: high-, low-, high-high- or low-low-level alarm.

▪ Linear (0)4-20mA or 0-10V analog output to represent the actual level. The (0)4-20mA or 0-10V

signal limits can be tuned.

Fig. 1: Typical application

FW_F170-A_M_v2201-01_EN.docx

Page 7

Configuration of the unit

The F170-A is designed for use in many types of applications. For that reason, a setup menu is

available to program the F170-A according to your specific requirements.

The setup includes several important features, such as span, engineering units, signal selection,

power management (to extend battery life-time), etc. All settings are stored in a non-volatile memory

and therefore saved in the event of a power failure or an exhausted battery.

Display information

The unit has a LCD with (optional) backlight to show the process information, status and alarm

messages. The display refresh rate is programmed in the setup menu.

At a key press, the display refresh rate will switch to FAST for 30 seconds. When 'OFF' is selected,

the display goes off after 30 seconds after the last key press. The display temporarily comes on after

a key press.

Options

The following options are available: isolated or active (0)4-20mA / 0-10V analog output, full Modbus

communication RS232/485/TTL (also battery powered), intrinsic safety, mechanical relay or active

output, power- and sensor-supply options, panel mount, wall mount and weather proof enclosures,

flame proof enclosure and LED backlight.

All F170 offer three alarm outputs. A fourth output (R4) is only available with type OS.

R4 may be mentioned in this manual since firmware and general functions are identical for all

2 OPERATIONAL

2.1 GENERAL INFORMATION

This chapter describes the daily use of the F170-A. This instruction is meant for users / operators.

• This device may only be operated by persons 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.

2.2 CONTROL PANEL

The control panel has three keys. The following keys are available:

Fig. 2: Control panel.

Functions of the keys

PROG-key

This key is used to program and save new values or settings.

The PROG-key is also used to gain access to SETUP-level; please read chapter 3.

SELECT-key

This key is used to SELECT the displayed information, like level and height.

CLEAR-key

This key is used to CLEAR values.

2.3 OPERATOR INFORMATION AND FUNCTIONS

In general, the F170-A will always function at Operator level. The information displayed is dependent

upon the SETUP-settings. The signal from the connected sensor is processed by the F170-A in the

background, whichever screen refresh rate setting is chosen. After pressing a key, the display will be

updated very quickly during a 30 second period, after which it will slow-down again.

Fig. 3: Example of display information during process.

For the Operator, the following functions are available:

▪ Display level / height / percentage

This is the main display information of the F170-A. After the selection of any other information, it

will always return to this main display automatically. The displayed information depends on the

configuration setting. When "-------" is shown, the value is too high to be displayed.

The arrows  indicate the increase/decrease of the level trend.

▪ How to program the alarm thresholds

The F170-A can give an alarm message on the display. When set to on, at the same time, the

digital outputs can give a signal for processing by an external device. Note that it is also possible

to set or change the alarm thresholds from the setup menu.

SENSOR

6.1

FILTER

The analog output signal of a sensor represents the actual level. This

signal is measured several times a second. 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.

The filter principle is based on three input values: the filter level (01-99),

the last measured analog value and the last average value. The higher the

filter level, the longer the response time on a value change will be.
