2. Design and function
2.3 Description
The model DI35 digital indicator is a multi-function and very accurate instrument for a
wide variety of measuring tasks.
The DI35-D is equipped with two inputs for standard signals (0/4 … 20 mA and
DC 0 … 10 V) that can be used in any combination. The display can show one of the two
input signals or a calculated value. Calculations can be made by means of the four basic
arithmetic operations (+ - * /) and an additional constant multiplier.
In addition, both versions offer the possibility to calibrate sensors and linearise using up
to 30 points. This allows further adaptation of the displayed values to different sensor
signals and application requirements. The standard features are completed by a transmitter power supply, a HOLD function and a TARE function for the correction of offset
shifts and sensor drifts. The sampling rate and display time can be configured and the
display can be dimmed. Unauthorised alteration of the set instrument parameters can
be prevented via different user levels, in conjunction with a freely selectable access
code.
Optionally available are up to four freely configurable switch contacts, an analogue
output signal and a serial interface.
Functions
Calculation function (4 basic calculation types, constant multiplier)
Analogue output
Retrieval of the MIN/MAX value
HOLD and TARE function
Linearisation of the measuring input
Semiconductor switching outputs (option)
Switch point display (option)
Adjustable switch points (option)

1. Remove the mounting elements.
2. Slide the seal over the digital indicator.
3. Slide the digital indicator into the control panel from the front.
Check the seal is properly seated.
4. Lock the mounting elements into place and tighten the clamping screws (max. 0.1 Nm).
5.3 Mounting, version in desktop case
▶▶ Connect the digital indicator to the socket using the mains connection cable.
5.4 Electrical connection
5.4.1 Notes on installation
■■ The supply must comply with overvoltage category II.
■■ Protect the power supply with a slow fuse of max. 0.5 A.
■■ For the panel-mounting version, a suitable isolation device must be provided.
■■ Route the signal input lines and signal output lines separately.
■■ Route outward and return lines side-by-side.
■■ Galvanically isolated potentials must be connected to a suitable point (e.g. earth or
plant ground).
■■ For high-accuracy requirements and small measurement signals, the sensor wires
must be shielded and twisted. The shield should be connected at one end only to a
suitable equipotential bonding (e.g. measurement ground).
■■ Avoid electrostatic discharges in the area of the terminals.

RS-465
The RS-485 interface is connected via a shielded data cable with twisted pairs. At
each end of the bus segment, a termination of the bus lines must be connected. This is
needed in order to ensure safe data transfer over the bus. For this, a resistor (120 Ω) is
inserted between data B (+) and data A (-).

Where interfaces are not galvanically isolated, the potential reference
between the interface and the measuring input can lead to a compensating current. This compensating current can influence the measuring
signals.

signal (DC 0 ... 10 V, 0 ... 20 mA, 4 ... 20 mA).
7.4.1 Start and end value
The analogue output can be assigned any measuring input. The output signal is
updated simultaneously with the measuring input. The refresh rate is determined by
the configured measuring time. The start and end value for the analogue signal can be
assigned user-defined measured values.
The start and end value define at which display value the minimum and maximum
output signal will be given. The display value is dependent upon the setting of the input
signal (→ see chapter 7.1.1 “Input signal”)

(= Configuration mode)
Description
In this mode, the digital indicator can be configured. Responses
will only be transmitted on request.
The current measured value can be queried via “A↵”.
Sending mode
Measured values are sent cyclically. The cycle corresponds to
the set measuring time.
Cancel sending mode
The sending mode is cancelled on receipt of “> ↵” and the instrument returns to standard mode.
Activate sending mode
Restart the digital indicator or transmit the command “S ↵”.
Protocol structure
Display values are transmitted in ASCII format. Minus signs and decimal points can be
displayed directly on a terminal display or processed by a PLC. Leading spaces are
disabled with transmission. With an over- or underflow, hyphens are transmitted “- - - - ↵”.
Example: “0.00 ↵”; “-9.99 ↵” ; “999.99 ↵”; “-123.45”; “ - - - - - ↵”; “Lbr ↵”
The display values can be processed or stored on a PC via a terminal program.

The TARE function sets the display value of the stored measuring input to zero. The
difference between zero and the display value is stored as an offset value.
The TARE function overrides a previously programmed offset shift of the
measuring inputs (PN4/9). Should the TARE function be used during a
measurement, the offset shift has to be reprogrammed.
The TARE function can be activated through the multi-function key or the digital input
(→ see chapter 7.7 “Setting special functions”). The key must be activated for at least 3
seconds.

The switching output is switched on only when the switch point, less the hysteresis, is
reached.

Switch-on delay
The switching output is switched on only when the input signal remains above the switch
point for at least the set switching delay.
This function prevents an unwanted switching of the switching output as a result of a
short-term fluctuation of the input signal.

Procedure
1. Set the number of interpolation points under PN100/PN140.
2. Apply the input signal for the first interpolation point, PN101/PN141, at the
measuring input.
3. Set the desired display value under PN101/PN141.
⇒⇒Input signal is associated with display value.
4. Repeat steps 2 + 3 for all interpolation points.
⇒⇒Input signal is linearised.

7.9 Linearising sensors
Non-linear sensors can be linearised with up to 30 interpolation points per measuring
input.
At each interpolation point, the input signal is assigned a new display value manually.
The analogue output is also linearised since it is proportional to the display values.

Linearisation of a pressure transmitter for 0 ... 100 mbar with an output signal of 0 ... 20 mA.

For PN101 this means:
With a pressure of 15 mbar, the transmitter delivers an output signal of 3.3 mA instead
of 3.0 mA. Therefore, before correction, the display shows 16.5 mbar. This value is
adjusted to 15.0 mbar using the interpolation point.

The factory settings can only be restored if the programming lock PN50 allows access
to all PNs or HELP is displayed. All application-specific data will be lost.
1. Switch off the power supply.
2. Press the multi-function key.
3. Apply power supply and hold the multi-function key for 2 s.
⇒⇒Factory settings are restored.
8.Faults
CAUTION!
Physical injuries and damage to property and the environment
If faults cannot be eliminated by means of the measures listed above,
the instrument must be taken out of service immediately.
▶▶ Ensure that pressure or signal is no longer present and protect against
accidental commissioning.
▶▶ Contact the manufacturer.
▶▶ If a return is needed, follow the instructions given in chapter 10.2
“Returns”.
