2.2 Intended use

Vacuum ovens VO are used for drying, testing, moisture determination, airtight storage, curing and degassing of substances or materials under vacuum, which are used in the procedures and specifications described in the operating instructions.

The appliance is not explosion-proof. The use of explosive substances or materials is abusive and can lead to hazards or damage. The appliance may only be loaded with materials and substances which cannot form any explosive vapours at the set temperature and which cannot explode, burst or ignite.

2.3 Function

The devices of the VO series (Fig. 3 1) can generate a vacuum in working chamber3 in conjunction with Memmert pump module 2 or another suitable vacuum pump. The vacuum inlet on the back of appliance 4 evacuates the working chamber through the pump.

Optionally, the working chamber can be supplied with inert gas through a connection on the rear of the appliance 56.

For temperature control thermal plates with electronic contacts are inserted into tube 7. If the electronic contacts are connected to the connections in rear panel 8, the thermoshelves can emit heat by direct contact with the load.

If toxic gases or vapours may be produced in the intended application, these must be safely discharged by the customer via an extraction system and cleaned if necessary 9.

2.6.2 Fresh air, inert gas and vacuum connection

At the left rear post are the connections for the inlet of fresh air or inert gas (optional) and the connection for the vacuum pump (DN 16 KF, Fig. 4 and Fig.

5).

Design and description

Fresh air

The fresh air connection has two functions. On the one hand, the device is ventilated via the connection and thus the negative pressure is adapted to the atmospheric pressure. On the other hand, the connection is opened by the appliance controller for a very short time in order to fine-tune the negative pressure.

(blanking plug) 2 Fresh air supply 3 Vacuum pump con-

nection

Inert gas (optional)

By applying inert gas to the working chamber, a protective atmosphere can be created which protects the load from contact with ambient air.

Vacuum

The vacuum connection is designed as an ISO-KF connection of size DN 16. Either the supplied pump module or another suitable external vacuum pump are connected to it.

When using an external vacuum pump, make sure that the pump is suitable for the material being fed and the desired process.

Required parameters of a suitable pump:

► Pumping speed > 30 Nl/min ► Final vacuum ≤ 3 mbar ► chemical-resistant version ► temperature resistant (exhaust gas temperature like working temperature)

2.6.3 Communication interfaces

The communication interfaces are intended for appliances which meet the requirements of IEC 60950-1.

USB interface

The appliance is fitted by default with a USB port in accordance with the USB specification. This way, you can

► transfer software stored on a USB stor-

age medium to the appliance (see page

59).

► export protocol logs from the appliance

to a USB storage medium (see page

61).

Fig. 6 USB interface

► transfer user ID data stored on a USB storage medium to the appliance (see page

62).

The USB port is located on the right of the ControlCOCKPIT (Fig. 6).

Ethernet interface

The appliance can be connected to a network via the Ethernet interface, so that you can transfer programmes created with the AtmoCONTROL software to the appliance and read out protocols. The Ethernet interface is located on the rear of the appliance (Fig. 7).

For identification purposes, each appliance connected must have its own unique IP address. Configuration of the IP address is described on page 50.

You will find a description of how to transfer programs via Ethernet in the enclosed AtmoCONTROL manual.

The appliance can be directly connected to a computer / laptop using an optional USB to Ethernet converter (see Scope of delivery on page 18).

2.6.4 Switching output for external vacuum pump purge valve and pump control

The 8-pin switching output on the rear right post (Fig. 8) is used to control the vacuum pump of the optional pump module (PM) through the vacuum oven (VO). The switching output is backwards-compatible with the 3-pole contact of older pump modules. For this purpose, plug the 3-pole cable into the 8-pole contact.

Fig. 8 Switching output

14 D39374 | Date 08/2018

Design and description

Vacuum pump rinsing valve

When drying feed materials with a high moisture content, the pump capacity may decrease during prolonged operation due to condensation in the pump heads. The diaphragms are blown free by briefly flushing the pump heads with fresh air.

This improves the efficiency of the drying process. In combination with the optionally available pump modules PM29, PM49 and PM101, this cyclical flushing takes place automatically when the pump output decreases. The drying process is thus faster and more energy-saving and the pump is protected.

Speed control and switch-off of the vacuum pump

After completing a drying program or after a long period of operation without a vacuum request from the controller, the vacuum pump installed in the pump module (PM) is switched off via the control line. The demand-controlled pump speed control saves energy, is low-noise and increases the service life of the vacuum pump by protecting the pump diaphragms.

Note: A control signal switches off the pump module (PM) installed in the optional vacuum pump. The operating light in the main switch of the pump module also lights up if the vacuum pump has been switched off via the control line.

2.7 Designation ( nameplate)

The nameplate (Fig. 9) provides information about the appliance model, manufacturer and technical data. It is attached to the front of the appliance, on the right behind the door.

Operation and control

NOTICE

► Check the chamber load for chemical compatibility with the materials of the appli-

ance (see page 12).

► A vacuum can be built up in the working chamber of the device. Fragile loads can be

damaged by the negative pressure. Make sure that you only use material that will not be damaged by negative pressure.

The chamber load is heated in vacuum operation exclusively by direct contact with the inserted thermal shelves. Before starting operation, check whether the thermoshelves are inserted and contacted. If not, insert the required thermoshelves (see also page 28) and check the contact on the temperature display on the ControlCOCKPIT (Fig. 25).

When loading, pay attention to the maximum permissible weight of 20 kg per shelf level.

5.4 Temperature monitoring

The appliance is equipped with multiple overtemperature protection (mechanical/electronic) in accordance with DIN 12 880. This serves to avoid damage to the chamber load and/or appliance in case of a malfunction:

► electronic temperature monitoring (TWW) ► automatic temperature monitor ( ASF) ► mechanical temperature limiter (TB)

D39374 | Date 08/2018 37

Operation and control

The monitoring temperature of the electronic temperature monitoring is measured via a separate Pt100 temperature sensor in the interior. Temperature monitoring settings are made via the

ALARM display. The settings made apply to all

operating modes.

If temperature monitoring has been triggered, this is indicated on the temperature display: the actual temperature is highlighted in red and a

warning symbol is shown ( Fig. 27 ). The type of temperature monitoring triggered (TWW in this example) is shown beneath the temperature.

If the acoustic alarm has been activated in menu mode ( by the speaker symbol

on the alarm display), the alarm is additionally signalled by an

Before reading how to adjust temperature monitoring (from page 39), please read the description of the individual monitoring functions here.

5.4.1 Electronic temperature monitoring ( TWW)

The manually set monitoring temperature min. and max. of the electronic overtemperature control is monitored by an adjustable over/undertemperature controller (TWW) protection class 3.1 acc. to DIN 12 880 (or over/undertemperature controller (TWW) protection class 3.1 for UIS appliances). If the manually set monitoring temperature is exceeded, the TWW takes overtemperature control and begins to regulate the monitoring temperature (Fig. 28).

Operation and control

5.4.2 Automatic temperature monitor ( ASF)

ASF is a monitoring device that automatically follows the set temperature setpoint within an adjustable tolerance band (Fig. 29).

The ASF – if switched on – is automatically activated as soon as the actual temperature value reaches 50 % of the set tolerance band of the setpoint (in the example: 180 °C -

1.5 K) for the first time (section A). When the temperature violates the set tolerance band around the setpoint (in the exam-

ple in Fig. 29: 180 °C ± 3 K) – e.g. if the door is opened during operation (section B of illustration) – the alarm is set off. The ASF alarm is automatically terminated as soon as 50 % of the set tolerance band of the setpoint (in the example: 180 °C ± 1.5 K) are reached again (section C).

If the temperature setpoint is altered, the ASF is automatically disabled temporarily (in this example: The setpoint is changed from 180 °C to 173 °C, section D), until it reaches the tolerance range of the new temperature setpoint (section E).

5.4.3 Mechanical temperature monitoring: Temperature limiter ( TB)

The appliance is equipped with a mechanical temperature limiter (TB) of protection class 1 in accordance with DIN 12 880.

If the electronic monitoring unit should fail during operation and the factory-set maximum temperature is exceeded by approx. 20 °C, the temperature limiter, as the final protective measure, switches off the heating permanently.

7.5 Calibration

The appliances are calibrated and adjusted at the factory. In case readjustment should be necessary later on – for example due to influence of the chamber load – temperature and pressure can be adjusted according to customer requirements with three individually selected adjustment points:

► Cal1Adjustment at low value ► Cal1Adjustment at middle value ► Cal1Adjustment at high value

To guarantee perfect control, we recommend to calibrate the appliance once a year.

7.5.1 Temperature calibration

For temperature adjustment, you will need a calibrated reference measuring device.

Each thermoshelf can be calibrated individually. This is only possible with the AtmoCONTROL software (see AtmoCONTROL manual for description).

Maintenance and Servicing

WARNING

Danger due to electric shock. Disconnect the mains plug before any cleaning or maintenance work.

CAUTION

Danger of cuts due to sharp edges. Always wear gloves when working in the interior of the chamber.

8.1 Cleaning

8.1.1 Interior and metal surfaces

Regular cleaning of the easy-to-clean interior prevents build up of material remains that could impair the appearance and functionality of the stainless steel chamber over time.

The metal surfaces of the appliance can be cleaned with normal stainless steel cleaning agents. Make sure that no rusty objects come into contact with the interior or with the stainless steel housing. Rust deposits can lead to an infection of the stainless steel. If rust spots should appear on the surface of the interior due to impurities, the affected area must be immediately cleaned and polished.

8.1.2 Plastic parts

Do not clean the ControlCOCKPIT and other plastic parts of the appliance with caustic or solvent-based cleaning agents.

8.1.3 Glass surfaces

Glass surfaces can be cleaned with a commercially available glass cleaner.

8.2 Regular maintenance

Once a year, grease the moving parts of the doors (hinges and lock) with thin silicone grease and check that the hinge screws are not loose.

To guarantee perfect control, we recommend calibrating the appliance once a year (see page 54).

8.3 Repairs and Service

WARNING

Repairs and service work are described in a separate service manual.
