Central control unit 15130 General description The Eltex multithread system is designed to monitor a number of simultaneously moving threads or wires. The central control unit provides a low voltage supply for the signal givers (yarn break sensors). It is equipped with sensitivity adjustment for all signal givers in the system. The central control unit also coordinates the signal from the signal givers and will give a stop signal to the machine or a warning signal depending on how it is connected. Application • Central control unit for up to 100 latching signal givers. • Central control unit for up to 100 SMG signal givers (max. 1800 eyelets). Technical features LED’s to indicate: • when the unit is sensing. • if the unit is not sensing because the inhibit input is activated. • if the unit has stopped because of broken thread. • if the unit has stopped because of false switch setting (ANTI-check). With the running mode input: the central control unit detects if the machine is running or not. The sensing of the yarn cannot normally be switched on immediately when the machine is started as the speed of the thread or wire is too low. With a DIP-switch on the board the unit can be set to start sensing after a delay or when the speed is above a threshold value. By start delay the running mode input will be connected to a contact on the machine that closes when the machine starts. This will activate the start delay, set by the potentiometer on the central control unit. When the start delay time is over the sensing will start. By speed dependent sensing the central control unit will switch on the sensing as soon as the machine speed is above a preset threshold value.
