5.2 Features of the unit
5.2.1 Easy set-up
• When the unit is supplied with operating voltage for the first time, the probe
length, the medium to be detected and the type of probe used must be entered�
Then the unit is ready for operation. (→ 10.2).
• If necessary, parameters for the output signals and optimisation of the
monitoring functions can be set ( → 10.3 to→ 10.5).
• All settings can also be carried out before installation of the unit�
• Reset to the factory settings is possible�
• Electronic lock can be set to prevent unintentional operations�
5.2.2 Display functions
The unit displays the current level, either in cm, inch or in percent of the final
value of the measuring range� Factory setting: cm� The display unit is defined by
programming (→ 10.3). In the Run mode, it can be temporarily switched between
length indication (cm / inch) and percentage:
► Briefly press [Set]�
> The selected unit is displayed for 15 s, the corresponding LED is lit� With each
push of the button the display type is changed�
The set unit of measurement and the switching status of the outputs are indicated
by LEDs�
5.2.3 Analogue function
The unit provides an analogue signal proportional to level�
The analogue output (OUT2) can be configured (→ 10.5 Setting of output signals).
• [OU2] defines the output function of the analogue output, current [I] / [InEG] or
voltage [U] / [UnEG] (→ 10.5.5).
• The analogue start point [ASP] defines at which measured value the output
signal is 4 mA / 0 V([OU2] = [I] / [U]) or 20 mA / 10 V ([OU2] = [InEG] / [UnEG])
(→ 10.5.6).
• The analogue end point [AEP] defines at which measured value the output
signal is 20 mA / 10 V([OU2] = [I] / [U]) or 4 mA / 0 V ([OU2] = [InEG] / [UnEG])
(→ 10.5.6).
Minimum distance between [ASP] and [AEP] = 25 % of the active zone�
