■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
6. Commissioning, operation
In hazardous areas, only use eld indicators that are approved for those
hazardous areas.The approval is marked on the product label.
6.1 Operating modes
The following operating modes are possible:
■
HART® slave / basic mode (4 ... 20 mA)
■
HART® master / basic mode / multidrop (models DIH52, DIH62)
6.1.1 Operating mode: HART®slave (models DIH50, DIH52, DIH62)
The digital indicators powered via the same current loop as the corresponding transmitters
monitor permanently the HART®communication. When modifying the unit or measuring
range of the connected transmitter, the unit of the digital indicator and the corresponding
indication range are adapted automatically.
However, it is required that the unit set in the transmitter is also set in the devices.
5. Transport, packaging and storage / 6. Commissioning, operation

WIKA operating instructions models DIH50, DIH52, DIH62 15
GB
14008548.03 05/2013 GB/D
A ashing ♥ symbol is shown on the display when a HART®communication takes place for
the rst time and the digital indicators are thus switched to the HART® mode. The ♥ symbol
is displayed permanently when the HART®communication is terminated and the digital
indicator is congured according to the measuring range and the unit of the connected
transmitter.
After the power supply was interrupted or the digital indicator was set manually, the ♥
symbol is no longer displayed.
During operation in the basic mode, the ♥ symbol is not displayed.
CAUTION!
The instruments react only to the HART®standard commands 15 and 35. If
a connected HART® transmitter is congured by means of other commands,
automatic setting is not possible!
The HART®function, i.e. the automatic adaptation of the display to the
congured data of the transmitter, requires a HART®communication between
the transmitter and the HART® software (e.g. WIKA_T32) or between the
transmitter and the eld communicator (e.g. FC375/FC475, MFC4150 etc.).
6.1.2 Operating mode: HART®master (models DIH52, DIH62)
The master mode enables the modication of the measuring range, the unit, the format,
the damping and the polling address of the connected HART®transmitter. Further
modications to the conguration of the transmitter (e.g. selection of the sensor) are not
possible.
During the starting procedure, the eld indicators try to contact the connected HART®
transmitter in the master mode and to apply its settings (unit and measuring range). During
the connection establishment, the status line shows the message "Connecting HART®".
When a HART®sensor is detected, the HART® symbol is displayed. The eld indicator
switches to the HART®mode and starts operation using the settings received from the
transmitter. This procedure is repeated whenever the power supply is switched on.
When pressing any key during the starting process or the device has not detected any
HART® transmitter during approx. 70 seconds, the digital indicator switches to the basic
mode and starts operation on the basis of the factory settings.

GB
14008548.03 05/2013 GB/D
6.1.3 Operating mode: Multidrop (models DIH52, DIH62)
In this specially dened operating state for HART® transmitters, the current signal is rmly
set to 4 mA and the measuring information is transmitted via the HART®communication
to the control room.To enable the displaying of the measured value of a transmitter, the
address of the desired transmitter must be set in the "Address" menu item.
If the HART® address is modied during operation, the establishment of a new connection
is started during which, however, the sensor must respond immediately in order to
complete the connection establishment.
The digital indicators show the measured values of the primary variable transmitted via
HART®to the control room.The display is passive, i.e. the transmission of the measured
values must be requested by the control room.The devices function as secondary master
with respect to the sensor during the parameterisation.
6.1.4 Operating mode: Basic mode, 4 ... 20 mA (models DIH50, DIH52, DIH62)
In the basic mode, all settings of the digital indicator must be carried out manually by
means of the front-side keys.
To navigate in the menu levels, four keys with the following functions are available:
▲ (UP) One menu item up
▼ (DOWN) One menu item down

7. Electrical connection
WARNING!
Observe the safety-relevant maximum values for the connection of the power
supply and the sensors dened in chapter 9.1 "Model overview and their
approvals".
When working on the eld indicators (e.g. installation/removal, maintenance work) take
measures to prevent electrostatic discharge from the terminals.
WARNING!
Carry out mounting work only with power disconnected!
Use the recommended cables and tighten the cable gland. Lead the connecting cable
downward before of the cable gland in order to provide additional protection of the device
against penetration of liquids. Rain water and condensed water can thus drip.
The device is connected by means of a commercially available two-wire cable without
screen. If electromagnetic interference exceeding the test values of EN 61326 for industrial
areas is to be expected or the HART®multidrop mode is used, a screened cable must
be used. Use cables with round cross section. An outside diameter of cable of 5 ... 9 mm
(0.2 … 0.35 inch) guarantees the tightness of the cable gland. When using other diameters
or cross sections, the gasket must be replaced or a suitable cable gland must be used.
Connect the cable screen on both sides to earth potential if a screened cable is required.
Connect the screen in the sensor directly to the internal earth terminal.The external earth
terminal of the case must be connected with low impedance to the equipotential bonding.
CAUTION!
If equipotential bonding currents are to be expected, a ceramic capacitor (e.g.
1 nF, 1,500 V) must be used for the connection on the evaluation side. The
low-frequency equipotential bonding currents are thus suppressed, but the high-
frequency interference signals remain.
