[ENG] [886A02] Installation and Connection
The converter can be mounted on a horizontal or vertical surface. There are mounting holes.
When you install the converter pay attention to the next restrictions:
Do not expose the converter to direct sunlight.
Do not install the converter near heat sources.
Do not open the converter case.
Avoid getting liquid on the converter particularly on the connectors.
The sequence of connection:
Step 1.
Remove the converter 886A02 from its packaging. Put it onto the place you need.
Step 2.
Connect the converter to the 1-wire port of the device (or through an extension-splitter) to which you are
connecting it. The host device must be disconnected at the time of connection, otherwise it can be rebooted.
Step 3.
Connect the sensor to the converter.

[ENG] [886A02] Loop/Sensor Connection to the Converter
Functions of the converter`s connectors
+24V and +12V — connectors which can give power to the sensor or loop;
RS+ and RS- — «meter» connectors;
GND — common connector.
General information
The main purpose of the converter is to measure the current flowing in the loop. Additionally, the converter can
measure the voltage on RS + and calculate the resistance based on the obtained values.
There are two possible schemes of connection:
Low-side — measuring only the flowing current. Voltage is not measured, resistance is not calculated. The loop is
closer to the power connector, the shunt is on the GND side.
High-side — measuring the flowing current and voltage, calculation of resistance. Voltage measurement error is up
to 60 mV at 30 mA. The loop is closer to GND, the shunt is on the side of the power connector. This scheme is
preferred.
The loop connection must always be in direct polarity - current must flow from RS+ to RS-. Reverse polarity
connection will not damage the device, but the measurement will be incorrect.

The example of connection
For convenience and clarity, we take a 10 kOhm variable resistor as a sensor, connected according to the High-side
scheme.
Thus, with the "middle" position of the resistor handle: 23,900 mV/4.86 mA = 4918 Ohm.
At the "ultimate" right position: 24,000 mV/2.4 mA = 10,000 Ohm.
It is possible to measure voltage (0...30V) by connecting the + of the power supply to the RS + connector and
connecting the GND of the power supply and the converter.
Attention!
In case of a short circuit at the output of the current loop power of the converter, it goes into protection. No
further recovery is possible without a power reset.

[ENG] [886A02] Warranty
The manufacturer guarantees normal operation of the product within 24 months from the date specified on the
warranty sticker if a buyer follows operating and storage conditions. Manufacturer warranty applies only to failure
of a device which occurred because of defects in manufacturing process of products and components used. If
during a warranty period the manufacturer receives a notice of such defects, it will repair or exchange the product
(by its own discretion). If the manufacturer is unable to repair or replace a flawed item during a period of time
determined by the current legislation, the manufacturer according to a customer’s wish can return the amount paid
for the product at the time of purchase. The manufacturer provides a limited warranty on firmware and device
configuration software. In case of detecting any errors in the software which became known to the manufacturer on
its own or from a customer, the manufacturer will fix these errors within a reasonable time and provide an update
for the customer. Only the errors that block normal use of the device at conditions and for performing functions
described in this User Guide are a subject to mandatory fix. This warranty does not apply to cases when defects
appear because of: a misuse of a device, any modifications of a device without a written permission of the
manufacturer, opening up a device (a warranty sticker on the case of a device is damaged)except cases foreseen by
this description; repairing by unauthorized personnel, using or storing a device out of the range of allowable
temperature and humidity, pressure, a software modification, and the reasons, listed below:
A device failed because of the problems in a public electric network, plugging a device into power supply
networks with invalid parameters, absence of grounding, etc. (power fluctuations and surges, overloading,
etc.);
A device failed because of having liquid inside;
A device failed as a result of extreme temperatures;
A device failed because of mechanical damage;
A device failed because of connecting a power supply unit with invalid output voltage or a defective power
supply unit;
There are foreign objects, insects, etc inside the enclosure;
During operation a voltage bigger than an allowable voltage range by the Ethernet standard has been
supplied to the ports of a device.

[ENG] [886A02] Operating and storage conditions
The converter is designed for continuous round-the-clock operation in closed spaces. In operating conditions the
converter is resistant to air temperature from -30°Сup to+50°С(without moisture condensation, at normal
humidity). The converter should be protected from direct sunlight and moisture.
The converter design provides reliable trouble-free operation during a long time without the necessity of special
maintenance.
The storage of converters is carried out at temperatures from -40 °Сup to +70 °С.
The content of dust, vapors of acids and alkalis, corrosive gases and other harmful impurities that cause corrosion
should not exceed the content of corrosive agents for type 1 atmosphere in ctorage rooms.
