1. BASIC REQUIREMENTS AND USER SAFETY

- The manufacturer is not responsible for any damages caused by

inappropriate installation, not maintaining the proper environmental

conditions and using the unit contrary to its assignment.

- 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.

- If the device is equipped with PE connector, it should be connected to PE wire.

Otherwise PE wire should be connected to GND connector.

- The unit must be properly set-up, according to the application. Incorrect

configuration can cause defective operation, which can lead to unit damage or

an accident.

- If in the case of a unit malfunction there is a risk of a serious threat to the

safety of people or property additional, independent systems and

solutions to prevent such a threat must be used.

- The unit uses dangerous voltage that can cause a lethal accident. The unit

must be switched off and disconnected from the power supply prior to

starting installation of troubleshooting (in the case of malfunction).

- Neighbouring and connected equipment must meet the appropriate standards

and regulations concerning safety and be equipped with adequate overvoltage

and interference filters.

- Do not attempt to disassemble, repair or modify the unit yourself. The unit

has no user serviceable parts. Defective units must be disconnected and

submitted for repairs at an authorized service centre.

User manual - CONTROLLER PUR-94

- In order to minimize fire or electric shock hazard, the unit must be protected

against atmospheric precipitation and excessive humidity.

- Do not use the unit in areas threatened with excessive shocks, vibrations, dust,

humidity, corrosive gasses and oils.

- Do not use the unit in areas where there is risk of explosions.

- Do not use the unit in areas with significant temperature variations, exposure to

condensation or ice.

- 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 UR-94 device has a universal input that can be configured to work as: a current

input (in the range 0 - 20mA), as a voltage input (in the range 0-10V and 0-150 mV), as an

RTD input (operating with Pt 100/500/1000 sensors) and as a TC input (operating K, S, J, T, N,

R, B and E type thermocouples). The device automatically compensates the temperature of

cold junction of thermocouple sensor. RTD and TC inputs feature full linearization of

characteristics. Only one input type can be used at a time. The exact measurement ranges of

the inputs are quoted in the next chapter. The measurement is shown on a 4-digit LED display.

The device can be equipped with 1, 2 or 4 relay outputs and one OC-type output (not

available in the 4 relay output version), which can be controlled from the measuring inputs via

Modbus protocol or a PID controller implemented in the device with two control loops and an

auto-tuning option. Optionally, the device (in version with two relays and OC-type output) can

be equipped with: an active current output, a passive isolated current output or an active

voltage output. An RS-485 communication interface and a sensor transducer power supply

output are available as standard. The device is available in two power supply versions.

Exact description of functions is provided in further section of the instruction.

The UR-94 is designed to regulate such processes as heating / cooling temperatures

with adjustable delay times for the operation of the output relays and controlling of valve levels.

User manual - CONTROLLER PUR-94 
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 connections 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 located 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 inside housings (control  panel, switchboard) 
insuring appropriate protection against surges and interference. Metal housings 
must   be   connected   to   ground   in   a   way   that   complies   with   the   governing 
regulations. 
- Disconnect the power supply prior to starting assembly.
- Check the connections are wired correctly prior to switching the unit on. 
In order to install the unit, a 90.5 x 43 mm mounting hole (Figure 4.1, 4.2) must be 
prepared. The thickness of the material of which the panel is made must not exceed 
5mm. When preparing the mounting hole take the grooves for catches located on 
both sides of the housing into consideration (Figure 4.1, 4.2). Place the unit in the 
mounting hole inserting it from the front side of the panel, and then fix it using the 
brackets (Figure 4.3). The minimum distances between the centre points of multiple 
units - due to the thermal and mechanical conditions of operation - are 115 mm x 
67mm (Figure 4.4).

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 a small 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 0.5 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 terminals (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.
