Ø of passage (mm) P. supply pressure : 4 bars Mounting recommendations - The elements should be mounted and piped in a clean atmosphere in order to prevent any form of pollution entering the system. - Minimum torque for element fixing screws: 5 cm/kg. - maximum torque for element fixing screws: 10 cm/kg. Characteristics common to all elements in the modular system - The characteristics have been obtained with a supply pressure at 6 bars. - The flow in NI/min is the number of litres of air at normal atmospheric pressure obtained with the output open to atmophere and the supply pressure at 4 bars - The consumption in NI/min is the number of litres of free air necessary for the unit to function. - kV = the flow coefficient of the equipment. - Mechanical life > 107 operations. Sequencer modules 4 P. supply pressure: 6 bars Flow (NL/mn) Module with auto reset Operation results from the combination of a sequential cycle. A system comprises individual modules which are joined together by means of a sub-base. Each module has a memory which delivers an output signal and receives an input signal. An indicator on each module allows the operator to monitor the progress 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 supply is lost Shift register Operation results from the combination of three functions (memory, AND and OR) which constitute each module. The memory activates the output and gives priority to the reset signal. 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 The general principle is to advance the sequencer step by command impulses to the inputs of the even steps, alternating with the command impulses to the inputs of the odd steps. Used for example on a transfer machine to shift the information "bad component" collected at a test-test "n" steps further along the machine to a reject station.

The appearence of signal "X1" causes the displacement of the slide valve. The output port "x" is then put under pressure. This state is remembered until the arrival of signal "X0". This signal reverses the slide valve, the output "x" is put under pressure. This state is likewise remembered. The output: - "x" under pressure indicates that the information in the MEMORY is "X1", - "x" under pressure indicates that the information in the MEMORY is "X0". 4 Dimensions Dimensions of logic and memory elements 81 523 201 - 81 523 601 2 holes Ø 3.2 depth minimum 2.5 (location) Viewed from above ATEX version products are available in the following catologues: Pneumatic products for explosive atmospheres or on our website www.crouzet.com 48 www.crouzet.com Timers fixed timing ■ Fixed 0.4 s Also available in ATEX version for use in potentially explosive atmospheres in accordance with 94/9/EC Directive 81 503 540 Positive output Version Symbol Characteristics Timing Operating pressure Flow at 6 bars Orifice diameter Accuracy Min. reset time Connection - On sub-base page 36-37 Operating temperature Mechanical life Weight s bar Nl/min mm % s 0.4 2➞8 170 2.7 ±5 10 7 106 l Principle of operation with positive output 4 Time Dimensions 81 503 540 ATEX version products are available in the following catologues: Pneumatic products for explosive atmospheres or on our website www.crouzet.com www.crouzet.com 49 Timers (with adjustable timing) ■ 60 s adjustable (60 s max.)
