- Do not use the unit in areas with significant temperature variations, exposed to
condensation or icing.
- Do not use the unit in areas exposed to direct sunlight.
- Make sure that the ambient temperature (e.g. inside the control box) does not
exceed the recommended values. In such cases forced cooling of the unit must
be considered (e.g. by using a ventilator).
The unit is designed for operation in an industrial environment and must
not be used in a household environment or similar.
2. GENERAL CHARACTERISTICS
The WW-30Pt is a simple digital panel indicator, equipped with Pt 1 /Pt 5 /Pt 1
type input, with automatic connection recognition (two, three or four wire sensor). The
measurement range spans from -1 °C to +6 °C, and input is fully linearised accordingly to
PN-EN6 751+A2:1999 standard. Result is showed on 4-digit LED display. Device WW-30Pt
is equipped with RS-485 / Modbus RTU communication interface.
The parameters (offset, baud rate) can be selected while ordering. The device can be
configured via IR remote controller or optionally by PC via RS-485 interface, or using simple
RS-232 to IR converter. Over more communication interface RS-485 enables data
transmission in any monitoring system equipped witch Modbus RTU protocol.
Easy assembling, small dimensions, precision and reliability are the basic trumps of WW-30Pt
indicators.
IR remote controller is not a part of the WW-30Pt and must be ordered separately.

4. DEVICE INSTALLATION
The unit has been designed and manufactured in a way assuring a high level of user
safety and resistance to interference occurring in a typical industrial environment. In order to
take full advantage of these characteristics installation of the unit must be conducted correctly
and according to the local regulations.
- Read the basic safety requirements on page 3 prior to starting the installation.
- Ensure that the power supply network voltage corresponds to the nominal
voltage stated on the unit’s identification label.
- The load must correspond to the requirements listed in the technical data.
- All installation works must be conducted with a disconnected power supply.
- Protecting the power supply clamps against unauthorized persons must be
taken into consideration.
4.1. UNPACKING
After removing the unit from the protective packaging, check for transportation damage. Any
transportation damage must be immediately reported to the carrier. Also, write down the unit
serial number on the housing and report the damage to the manufacturer.
Attached with the unit please find:
- user’s manual,
- warranty,
- assembly brackets - 2 pieces.
4.2. ASSEMBLY
- The unit is designed for mounting indoor inside housings (control panel,
switchboard) assuring appropriate protection against electric impulse waves.
Metal housing must be connected to the grounding in a way complying with the
governing regulations.
- Disconnect the power supply prior to starting assembly.
- Check the correctness of the performed connections prior to switching the unit on.
In order to assembly the unit, a 67 x 32.5 mm mounting hole (Figure 4.1) must be
prepared. The thickness of the material of which the panel is made must not exceed
5mm. Place the unit in the mounting hole inserting it from the front side of the panel,
and then fix it using the brackets (Figure 4.2). The minimum distances between
assembly holes’ axes - due to the thermal and mechanical conditions of operation -
are 91 mm x 57mm (Figure 4.3).

4.3. CONNECTION METHOD
Caution
- Installation should be conducted by qualified personnel . During installation all
available safety requirements should be considered. The fitter is responsible for
executing the installation according to this manual, local safety and EMC
regulations.
- The unit is not equipped with an internal fuse or power supply circuit breaker.
Because of this an external time-delay cut-out fuse with minimal possible nominal
current value must be used (recommended bipolar, max. 2A) and a power supply
circuit-breaker located near the unit. In the case of using a monopolar fuse it must
be mounted on the phase cable (L).
- The power supply network cable diameter must be selected in such a way that in
the case of a short circuit of the cable from the side of the unit the cable shall be
protected against destruction with an electrical installation fuse.
- Wiring must meet appropriate standards and local regulations and laws.
- In order to secure against accidental short circuit the connection cables must be
terminated with appropriate insulated cable tips.
- Tighten the clamping screws. The recommended tightening torque is .5 Nm.
Loose screws can cause fire or defective operation. Over tightening can lead to
damaging the connections inside the units and breaking the thread.
- In the case of the unit being fitted with separable clamps they should be inserted
into appropriate connectors in the unit, even if they are not used for any
connections.
- Unused clamps (marked as n.c.) must not be used for connecting any
connecting cables (e.g. as bridges), because this can cause damage to the
equipment or electric shock.
- If the unit is equipped with housing, covers and sealing packing, protecting
against water intrusion, pay special attention to their correct tightening or clamping.
In the case of any doubt consider using additional preventive measures (covers,
roofing, seals, etc.). Carelessly executed assembly can increase the risk of electric
shock.
- After the installation is completed do not touch the unit’s connections when it is
switched on, because it carries the risk of electrical shock.
Due to possible significant interference in industrial installations appropriate measures
assuring correct operation of the unit must be applied. To avoid the unit of improper
indications keep recommendations listed below.
–Avoid common (parallel) leading of signal cables and transmission cables together with
power supply cables and cables controlling induction loads (e.g. contactors). Such cables
should cross at a right angle.
–Contactor coils and induction loads should be equipped with anti-interference protection
systems, e.g. RC-type.

User manual for digital indicator with Pt100/500/1000 input WW-30Pt
–Use of screened signal cables is recommended. Signal cable screens should be
connected to the earthing only at one of the ends of the screened cable.
–In the case of magnetically induced interference the use of twisted couples of signal
cables (so-called “spirals”) is recommended. The spiral (best if shielded) must be used
with RS-485 serial transmission connections.
–In the case of interference from the power supply side the use of appropriate anti-
interference filters is recommended. Bear in mind that the connection between the filter
and the unit should be as short as possible and the metal housing of the filter must be
connected to the earthing with largest possible surface. The cables connected to the filter
output must not run in parallel with cables with interference (e.g. circuits controlling relays
or contactors).
Connections of power supply voltage and measurement signals are executed using the
screw connections on the back of the unit’s housing.
