5.1 Wiring
CAUTION
Switch on the power supply only after the wiring of the device has been completely
performed
►
NOTICE
Switch off the device before checking the sensor and connection lines.
For circuit integrity check use only the measuring device with the output voltage max.
4.5 V to prevent the device damage. Disconnect the sensor in case of higher voltage.
►
NOTICE
Signal cables should be routed separately or screened from the supply cables.
Only a shielded cable may be used for signal lines.

6 Configuration
Each of the 10 display segments can be in one of the following states:
off
green light
red light
fast flashing (red/green)
slow flashing (red/green)
The display is shown in drawn in horizontal position. The following symbols are used:
Fig. 6.1 Diagram symbols
The display segments light green or red depending on the input signal value and the set
alarm limits (sect. 6.1.). The NPN output can be switched on/off using the same alarm limits
(Table 6.2, parameter 2).
The indicator can be configured with 3 function buttons on the rear part of the device (Table
6.1).

Press the button for 3 seconds to enter the configuration mode. The first parameter will be
shown on the display as follows:
The number of red segments on the right side of the display is the parameter number.
Press the button to save the parameter and go to the next one.
The number of green segments on the left side of the display is the parameter value
x10%. Use the buttons and to change the parameter value. The slow flashing
segment is the one being currently changed.
All parameters and its values are explained in Table 6.2. Default values are highlighted in
bold.

6.1 Alarm limits
The alarm limits are the signal levels at which the segment color changes and the output
switches on or off depending on the value of the parameter 2. "Output control" (Table 6.2).
To set up the upper (HL) and lower (LL) limits, press and hold the button for 3 seconds
and then proceed in accordance with Fig. 6.3.

Fig. 6.3 Alarm limits adjustment
To set LL to 0% and HL to 100%, set the first and the last segments to “fast flashing red”
using the buttons and , then press to save and quit (Fig. 6.4 a, b).
If you need only one limit (lower or upper), press and hold the button for 3 seconds, set
the first or the last segment to “slow flashing green” using the button or , and press
to save and quit (Fig. 6.4 b, c).

Fig. 7.1 Operation display
Each segment corresponds to 10% of the measurement range.
In case of a fault in the 4-20 mA and 2-10 V input circuit (short circuit or sensor break), the
three right and left extreme segments flash in red (Fig. 7.2) and the output is set to the state
defined in the parameter 3. “Output safe state” (Table 6.2).
Fig. 7.2 Fault indication
For signals 0-20 mA and 0-10 V, short circuit and sensor break are indicated as 0%. The
output will not be set to the safe condition.
If the indication does not correspond to the real process value or when indicating an error,
check the set signal type matches the real signal (Table 6.2, parameter 1).
8. Maintenance
The device is maintenance free.
If necessary, the device should be cleaned with a damp cloth only. No abrasives or solvent-
containing cleaners may be used.
9. Transportation and storage
Pack the device in such a way as to protect it reliably against impact for storage and
transportation. The original packaging provides optimum protection.
If the device is not taken immediately after delivery into operation, it must be carefully stored
at a protected location. The device should not be stored in an atmosphere with chemically
active substances.
Permitted storage temperature: -25…+55 °C
