General characteristics
Operating fluid
- Compressed air or inert gas.
Conditions of use
- Operating pressure 2 at 8 bars (except for special conditions).
- Fluid: Filtered air to 50 microns - non lubricated.
- Operating temperature from - 5° C to + 50° C (under + 5° C the dew
- For optimum performance, the elements should be inter-connected
Mounting recommendations
- The elements should be mounted and piped in a clean atmosphere
- Minimum torque for element fixing screws:
- maximum torque for element fixing screws:
Characteristics common to all elements in the modular system
- The characteristics have been obtained with a supply pressure at 6
- The flow in NI/min is the number of litres of air at normal
- The consumption in NI/min is the number of litres of free air
- kV = the flow coefficient of the equipment.
- Mechanical life > 10
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

This maintains the memory spool in position only when the supply is lost.
Sequencer modules
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.

This returns the memory spool to the reset condition only when the

Shift register
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.
