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 point must be below 10° C for the application).
- For optimum performance, the elements should be inter-connected
by air supply tubing with an internal diameter at 2.5 mm.
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 atmosphe-
ric 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 neces-
sary for the unit to function.
- kV = the flow coefficient of the equipment.
- Mechanical life > 107 operations.
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 pro-
gress of the cycle and identity quickly and easily any fault which may
occur.
General characteristics
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
Function diagram
Brake
This returns the memory spool to the reset condition only when the
supply is lost
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.

Cellule OR
The output signal "S" is present when a signal at
"a" OR "b" is present:
S = a OR b S = a + b

The output signal "S" is present only when signals
"a" AND "b" are present simultaneously:
S = a AND b S = a . b

YES element
The output signal "S" is only present when the
pilot is present "a" is present:
S = a YES b S = a
NOT element
The output signal "s" is present only if the input signal
"a" is NOT present. The output signal is therefore the
inverse of the pilot signal:
S= NOT a S = a
If the supply port is connected to a 2nd input "b", the
function obtained is called inhibition:
S = NOT a AND b S = a . b

The function is that of a 4/2 valves. 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".

Principle
The operation of these pneumatic timers is similar to that of
electronic timers (circuit with capacitor/resistor)
Timing by charging of reservoir
The reservoir fills via the flow restrictor until the switching point
of the timer output is reached (positive or negative).
The non-return valve allows the reservoir to be emptied rapidly
for the next timing.
