107-112 range

APPLICATION
●
This assembly provides the two following main functions:
- Pneumatic system venting.
- Gradual pressurisation after an outage leading to venting
of the system.
●
These products allow for machines to meet compliance
regulations.
OPERATING PRINCIPLE
■ ■ ■ ■ ■ SHUT-OFF VALVE
The 3/2 NC shut-off valve, controlled by a solenoid valve of the CNOMO pad-mounting type, vents the system
by de-energising the solenoid valve.
■ ■ ■ ■ ■ SOFT-START DEVICE
Upon pressurisation, when the soft-start device is in its initial position, an adjustable air flow ensures gradual filling
of the downstream circuit, so that the actuators move slowly. The transition to the full flow position depends on
which of the following soft-start devices is chosen:
●
AUTOMATIC SOFT-START DEVICE (Modulair 107-112)
Automatic switch-over to the full flow position as soon as the downstream pressure reaches 60 to 70% of the
supplied pressure (upstream pressure). Operating cycles take place at normal speed thereafter.
The soft-start device remains in the full flow position as long as the upstream pressure is maintained.
The device returns into its initial position when the air supply is cut off.
●
SOLENOID/AIR CONTROLLED SOFT-START DEVICE (Modulair 112)
This device, which complies with technical CNOMO specifications (E05.03.135.N), can be used to gradually feed air
into the system whenever restarting after a shutdown or a pressure cut-off. The system is slowly returned into the
end-of-cycle position. As soon as this condition is reached, the solenoid pilot valve is energised in accordance with
the automatic control specified by the user. The soft-start device then switches to the full flow position allowing
the subsequent operating cycles to take place at normal speed. The solenoid pilot valve must be kept energised
under normal operating conditions. Any de-energisation of the solenoid pilot valve sets the soft-start device into
the low flow position.Any de-energisation of the solenoid valve sets the soft-start device to the low flow position.
Note: In both soft-start device versions, the filling rate, i.e. the pressure build-up in the downstream circuit, is adjusted by means
of a fine-thread screw with can be locked to prevent unauthorised adjustment of regulated pressure.
