Please understand that NO information will be lost; the input signal will be
processed and the output signal will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - off.
Example battery life-time:
battery life-time with a FAST update: about 3 years.
battery life-time with a 1 sec update: about 5 years.
Note: after a button has been pressed by the operator - the display
refresh rate will always switch to FAST for 30 seconds. When "OFF" is
selected, the display will be switched off after 30 seconds and will be
switched on as soon as a button has been pressed.
BATTERY-MODE
42
The unit has two modes: operational or shelf.
After "shelf" has been selected, the unit can be stored for several years; it
will not process the sensor signal; the display is switched off but all
settings are stored. In this mode, power consumption is extremely low.
To wake up the unit again, press the SELECT-key twice.

FW-F070-U-M_v0403_05_EN.docx
Page 15
5 - SENSOR
FILTER
51
The analog output signal of a sensor does mirror the actual level. This
signal is measured several times a second by the F070-U. 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 principal 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.
Below, several filter levels with there response times are indicated:

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).
▪Do ground the aluminum casing properly as indicated, if the F070-U has been supplied
with the 115-230V AC power-supply type PM. The green / yellow wire between the back-
casing and removable terminal-block may never be removed.
Fig. 7: Grounding aluminum enclosure with type PM 115-230V AC.
FOR INSTALLATION, PAY EMPHATIC ATTENTION TO:
▪Separate cable glands with effective IP67 (NEMA4X) seals for all wires.
▪Unused cable entries: ensure that you fit IP67 (NEMA4X) plugs to maintain rating.
▪A reliable ground connection for both the sensor, and if applicable, for the metal casing. (above)
▪An effective screened cable for the input signal, and grounding of it’s screen to the “┴“ terminal
or at the sensor itself, whichever is appropriate to the application.
