Packaginng, transportation, storage
The submodule is packed in a paper box according to the internal packing instructions. This documentation is also part of the package. The outer packaging is carried out according to the scope of the order and the method of transport in transport packaging provided with transport labels and other data necessary for transport. Transport from the manufacturer is carried out in the manner agreed upon when ordering. The transport of the product by the customer's own means must be carried out by covered means of transport, in the position specified by the label on the packaging. The box must be stored in such a way that it does not move spontaneously and the outer packaging is not damaged.

The product must not be exposed to direct weather conditions during transport and storage. Transport is permitted at temperatures of -25 ° C to 70 ° C, relative humidity of 10% to 95% (non-condensing) and a minimum atmospheric pressure higher than 70 kPa. The product may only be stored in clean rooms free of conductive dust, aggressive gases and vapors. The most suitable storage temperature is 20 ° C.
Attention! The modules contain components sensitive to electrostatic charge, so we observe them principles for working with these circuits! We handle only on the module disconnected from the power supply! When replacing the submodules, the correctness of the deployment must be carefully checked of the submodule cavities against the tips on the motherboard. The tubes have no coding position and incorrect installation, may occur when the power is turned on again damage to the submodule or even the motherboard !!!
Exchangeable submodules The installation of the submodule in the terminal device is always described in the documentation of the respective device.

The submodule is mounted on the tips in the terminal device so that the 14-socket socket of the submodule is exactly opposite the 14-pin connector and the 13-socket socket is mounted on the tips of the connector, three-row connector.
Description Terminal communication interfaces are typically equipped with connectors. Connection
connectors is specified in the documentation of the respective system where the submodule is used.
Module operation
Module configuration The MR-0106 submodule has solder jumpers on the printed circuit board in the position marked 4. The CH4 channel works as an RS-485 interface. Jumpers BT2 and BT3 connect the impedance termination for the RS-485 line when the device is at the end of the communication line. By default, submodules are supplied with the most commonly used RS-485 settings, without termination. The block diagrams in the following figures illustrate the meaning, location and connection of the individual jumpers.
Generally Warranty and complaint conditions are governed by the Terms and Conditions of Teco a.s.
Warning You must meet all the conditions of this documentation before turning on the system. The system must not be put into service unless it has been verified and confirmed that the machinery of which the control system forms part complies with the requirements of Directive 89/392 / EEC, in so far as it applies to them.
