Packaginng, transportation, storage
Description The module is packed in a paper box. 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 a transport package provided with labels and other data necessary for transport. The product must not be exposed to direct weather conditions during transport and storage. Malting of the product is only allowed in clean rooms without conductive dust, aggressive gases and vapors. The most suitable storage temperature is 20 ° C
Assembly description The installation of the TC800 system module is carried out by sliding it perpendicularly onto the DIN rail ČSN EN 50022 with busbar and locking latch in the lower part of the module. A more detailed description and mechanical drawings with dimensions are given in the documentation TXV 004 72.
Warning All external circuits connected to the module must meet the conditions for SELV circuits!
Connection description The module is equipped with a screwless removable connector with 34 terminals with locking after insertion into the module.
Power connection Via the system bus
Connection of inputs / outputs Connector with screwless terminals 0.2 ~ 1.5 mm2
Connector coding The connector can be provided with a code to prevent its insertion into another type of module. Modules with connectors are delivered without coding, coding elements can be ordered separately.
Module installation tools (-) 2 mm, flat screwdriver
Connection description An example of module connection is shown in the following figure.
Module operation
Module configuration The module is operated, set up and diagnosed from the Mosaic development environment.
Commissioning On the module, the DIP switch in the left part of the case sets a unique address within one frame. The module is fully ready for operation after inserting it into the frame and turning on the power supply.
Module diagnostics The basic diagnostic system of the module is part of its standard software. It has been in operation since the module power was turned on and works independently of the user. Diagnosed error states of the module and connected peripheral modules of the assembly are signaled in the status word of the module and on the module panel
Description The module does not require any maintenance under general installation conditions. The operations in which a part of the module has to be dismantled must always be carried out with the supply voltage disconnected.
Notice Because the module contains semiconductor components, it is necessary to follow the principles for working with electrostatic sensitive components when handling the removed cover. It is not allowed to directly touch the printed circuit boards without protective measures !!!
Generally Warranty and complaint conditions are governed by the Terms and Conditions of Teco a.s.
Notice 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 meets the requirements of Directive 89/392 / EEC, in so far as it applies to it. Documentation subject to change.
