They are controlled via solenoid valves or power contactors.
Any other use is considered improper.

Qualification of qualified personnel
Installation, commissioning, maintenance and troubleshooting of the NAS may only be performed by authorised qualified personnel, who have basic knowledge in electrics and mechanics.
All handling of the NAS is the responsibility of the operator.

High voltage
DANGER
Risk of electric shock due to high voltage
Live parts can cause severe injuries or even death.
Installation, connection, commissioning, maintenance and disassembly of the NAS may only be carried out by authorized qualified personnel.
The housing of the NAS must not be opened when live.
Installation, connection, maintenance and disassembly may only be carried out in a voltage-free state.
When handling the NAS the provisions and regulations of the local electrical engineering associations (e.g. VDE) and the accident prevention regulations must be observed.
Perform all work only with insulated tools suitable for the application.

Safety rules

DANGER
Electric shock
An electric shock will result in serious injury or even death. The NAS must be free of voltage during assembly, start-up, maintenance and troubleshooting.
Observe the following five safety rules:

1. Disconnect the NAS from the mains supply.
2. Secure the NAS against re-activation.
3. Establish that the NAS has no voltage.
4. Earth and short-circuit the power supply of the NAS.
5. Cover adjacent live parts or fence them off.

Electric shock
DANGER

Danger of electric shock due to incorrect or wrongly laid electrical cables
Incorrect or improperly laid electrical wiring can cause electric shock and result in serious injury or even death.

Lay electrical cables carefully. Make sure that electrical cables are not worn through vibrating parts or sharp edges.
Protect the electrical lines from high temperatures and lubricants.
Only use suitable, flexible feed cables to connect the NAS. The conductors in the supply cable must be temperature-resistant and have a sufficiently large crosssection matched to the cable length.
Check the perfect condition of the electric cables and plugs regularly. Detected errors must be eliminated immediately.

Automatic start-up

WARNING
Risk of injury due to automatic start-up
If the mains connection is supplied with voltage again after a voltage interruption, the next cycle always starts with the set working time. The output of the NAS is immediately energized. Automatically starting vibrators and drives can lead to serious personal injury.

Check that the vibrators or drives can start up without danger before applying voltage to the mains connection.

Design and function

Function
The NAS are suitable for the cycled actuation of up to 8 pneumatic or elec-tric vibrators. The sequence begins with the duty time (PULSE), which can be set to between 0.5 s and 30 s. During this time, 24V DC is applied to the connected output.
When the duty time elapses, the pause time (PAUSE) runs for 2 s to 540 s. This cycle then moves to the next output. Once all connected outputs have been processed once (duty time and pause time), the sequence starts again at the first connected output.

Transport and storage

Transport conditions
Special conditions of transport are not required.

Packaging
The NAS are packed ready for installation.
The packaging protects the NAS from transport damage. The packaging material has been selected from an environmentally safe and technically disposable point of view and is therefore recyclable.
The return of packaging to the material cycle conserves raw materials and reduces the amount of waste.

Storage

• Store the NAS in a dry and clean environment.
• The permissible storage temperature is between -20 °C and +50 °C.
• The permissible relative humidity is max. 60 %.
• Do not store the NAS outdoors. The electrical components are not protected against corrosion.

Installation

 Mount and connect NAS

Observe the safety instructions in chap. Safety, starting on page 5.

1. Unscrew the four crosshead screws from the cover.
2. Remove the cover.
3. Screw the NAS onto a clean and flat mounting surface (± 0.1 mm flat- ness) using suitable screws via the mounting holes.
   The NAS can be mounted in any position.
4. Connect the NAS via the terminals on the connector block, see chapter “Design”, section “Connector block”.

Inputs
The solenoid valve control has 2 inputs: START and START CYCLE. The inputs are supplied with + 24 V DC internally and can be switched to (-) with a potential-free contact.

Outputs (valves)

Connection	Terminals V1 to V8 (+ and -)
Valve type	24 V DC, max. 1 A, min. 0,5 W
Shared potential	–
Switched output	+

The outputs are short-circuit proof.

Commands

Start-up and operation

Observe the safety instructions in chap. Safety, starting on page 5.

Permissible operating conditions
Please refer to chap. Technical data, page 7 for permissible operating conditions.

Regulations
Installation work as well as operation of the system are to be carried out taking the valid accident prevention regulations into account.
The operator is responsible for the proper condition of the system.

Measures
Carry out the following measures before start-up:

1. Check the mains voltage and the grid feed-in.
2. Check that the system is in perfect electrical condition.
3. Check that all protective measures on the system have been observed.
4. Check that the cables are undamaged and laid according to the known regulations and standards.
5. Eliminate possible errors.

Adjusting the duty time

WARNING:
When switched on the NAS starts immediately with the stored time values.
The connected vibrators start immediately. The output is immediately energized.

Coding switch Cycles		Set the number of cycles from 1 to 9. The set number of cycles is processed, after which the cycle control stops; the “Cycle” function is deactivated in position 0.
LED operation (green)		Lights up when operating voltage is applied and processor is active.
Potentiometer PULSE		Set the duty time from 0.5 s to 30 s using the PULSE potentiometer.
LED PULSE (yellow)		The LED lights up during the actuation time (pulse).
Potentiometer PAUSE		Set the pause time from 2 s to 540 s using the PAUSE potentiometer.
LED PAUSE (yellow)		The LED lights up during the pause until the next valve is actuated.
Button TEST		Pressing the button once starts a pulse and a pause at the next output. Pressing the button again interrupts the pause of the active output or starts the next output. If you press the button for longer than 2 seconds, the set number of cycles is processed. If the coding switch cycles is set to zero, continuous operation is carried out as long as the button is pressed.
LED TEST (green)		The LED lights up for the entire duration of a test.
Outputs V1 to V8 with status LEDs		The connected devices are automatically recognized by the control unit. Detected devices are indicated by a glowing LED (red). When the output is switched, the LED lights up. The control unit only ever processes the connected outputs with the set working and pause time. Unused outputs are skipped in the cycle.
Input Cycle start (trigger signal)		The set cycle starts with a trigger signal at the cycle terminal (+ and -).
Input START (Continuous signal)		Continuous operation is carried out as long as a signal is present at the START terminal.

Interval	Action
If required	Remove dust deposits from the housing of the NAS with a lint-free cloth.
Every 6 month	Check proper condition of connecting cables and plugs. When the NAS is exposed to constant weather influences: Check the seal in the cover and the electrical cables for porosity. Replace porous seal and leads.
At least every 4 years	Check proper condition of electrical systems and stationary electrical equipment.

Troubleshooting

Observe the safety instructions in chap. Safety, starting on page 5.

Expertise and regulations
Electrical faults may only be processed by a qualified electrician. Work on the NAS may only be carried out by authorised persons.
In the case of unauthorised intervention in the NAS there is no longer any warranty claim. Interventions of any kind are to be agreed upon with NetterVibration.

Malfunctions and causes
In the case of malfunctions of the NAS proceed as follows:

Malfunction	Possible causes	Corrective action
NAS does not start	Phase interruption	Check fuse (for 24 V version) and connection cables and replace if necessary.
	Mains voltage too low	Adjust mains voltage. Check cables and replace if necessary.
	Cable cores are connected with reversed polarity	Connect cable cores in correct polarity.

Disposal

Disposal

All parts of the NAS must be disposed of properly according to the material specifications. Do not dispose the electrical and electronic components of the NAS in the normal household waste, but in a special collection point for the environmentally friendly disposal of electrical equipment.
