A (supplied without logic element. For choice of units see pages 46/47) system comprises individual modules which are joined together by means of a sub-base. Each module has a memory which delivers an Sequencer module with maintained reset Shif register with maintained reset output signal and receives an input signal. An indicator on each module allows the operator to monitor the pro- gress of the cycle and identity quickly and easily any fault which may occur. Brake This returns the memory spool to the reset condition only when the 1 - Input signal 1 - Input signal supply is lost 2 - Supply 2 - Supply 3 - Output signal 3 - Output signal Shift register 4 - Start signal 4 - Start signal The general principle is to advance the sequencer step by command 5 - In cycle signal 5 - In cycle signal impulses to the inputs of the even steps, alternating with the command 6 - End of cycle signal 6 - End of cycle signal impulses to the inputs of the odd steps. 7 - Reset to zero signal 7 - Reset to zero signal Used for example on a transfer machine to shift the informationbad componen collected at a test-test steps further along the machine Dimensions Mounting plan for sequencer Operation results from the combination of three functions (memory, to a reject station. AND and OR) which constitute each module. 2 holes M4 - minimum Function diagram The memory activates the output and gives priority to the reset signal. depth 7 mm The AND element ensures the transition to the next module but only if an input signal is present. The OR element ensures the resetting of all previously operated modules Function diagram Auto reset sequencer module ATEX version products are available in the following catologues: Pneumatic products for explosive atmospheres or on our website www.crouzet.com sequencer module with maintained reset Brake This maintains the memory spool in position only when the supply is lost.
