Do not install and operate the vacuum drying oven VDL in hazardous locations.

DANGER

Explosion hazard.

Danger of death.

∅ Do NOT operate the chamber in potentially explosive areas.

 KEEP explosive dust or air-solvent mixtures AWAY from the chamber.

The vacuum drying ovens were constructed in accordance with the applicable VDE regulations and were
routinely tested in accordance with VDE 0411-1 (IEC 61010-1). The production underlies an internal
monitoring according to ATEX Directive 2014/34/EU appendix VIII.

For the user there is no risk of temporary overvoltages in the sense of EN 61010-1:2010.

Even when the equipment is used properly, there exists a residual risk of explosion that cannot be ex­cluded, particularly in relation to the environment of the chamber. To minimize this risk, strictly observe
the legal regulations about how to select an appropriate location.

DANGER

Explosion hazard.

Danger of death.

 Strictly observe the legal regulations about how to select an appropriate location.

The walkable operating surface in the front area of the chamber must be conductive. This operating sur­face must be connected to the existing grounding concept of the vacuum drying oven. Cyclic measure­ments are required.

The operator must ensure adequate ventilation of the loading area in front of the chamber before starting
up the chamber. The loading and the removal of the charging material takes place under technical venti­lation (suction) in the security area in front of the chamber.

through barrier) according to EN

1.5.2 Safety instructions on vacuum supply

Within the European Union, units that will be operated in potentially explosive areas have to meet the
requirements of ATEX Directive 2014/34/EU.

If combustible solvent is introduced into the drying chamber, the vacuum pump must be constructed in a
suitable explosion-proof manner.

Observe the safety instructions of the pump manufacturer.

The mixtures extracted from the inner chamber must be carried away making sure that there is no danger
by ignition of these atmospheres. Otherwise, use flame arresters (flame flash-through barrier). For in­stalling a flame arrester, please contact the BINDER INDIVIDUAL team.

In case of an explosion, the flame can be suctioned into an in-house vacuum system thereby resulting in
further explosions.

DANGER

Danger due to flame flash-through with in-house vacuum system.

Danger of death.

We recommend installing a flame arrester (flame flash­ISO 16852:2010 between the VDL vacuum drying oven and the in-house vacuum system.

Sparking in the pump motor or the switching elements, electrostatic discharges, as well as hot pump
parts can ignite solvent vapors in the event of an error. To minimize this risk, use an ATEX Directive
2014/34/EU compliant vacuum pump suitable for suction from Zone 0 or 1 and, if appropriate, from the
zone of its installation site.

DANGER

Ignition of emerging solvent vapors due to sparking in the pump motor or the
switching elements, electrostatic discharges, hot pump parts.

Explosion hazard.

Danger of death.

 Use only suitable, explosion-proof pumps
 Operate the pump in a stationary position and secure it so it is immobile.
 Install a fixed and conductive suction line to the vacuum connection (13).
 Install a fixed and conductive exhaust pipe in case it may conduct ignitable solvent

concentrations. This should be avoided by sufficient solvent condensation e.g., in an
exhaust waste vapor condenser

 When using ATEX Directive 2014/34/EU non-compliant pumps: Provide a current-

dependent, delayed protective device for the pump (for the triggering time of this pro­tective device, see the manufacturer’s specifications). The protective and monitoring
device must not be able to turn on independently again or be released.

 When using ATEX Directive 2014/34/EU non-compliant pumps: Install the switch gear

box outside the hazardous area or provide it with explosion protection.

 Assure equipotential bonding between the pump housing and the housing of the VDL

vacuum drying oven by the connected equipment grounding conductors of both units.

VDL (E2.1) 05/2016 page 11/108

The ATEX Directive 2014/34/EU compliant pumps offered by BINDER provide an integral
protective device.

The ATEX Directive 2014/34/EU compliant pumps offered by BINDER provide an integral
explosion proof switch.

Confirm that the vacuum source is designed for a gas inlet temperature corresponding to the
used drying temperature, or take appropriate measures to cool down the extracted vapor be­fore it enters the vacuum source.

The ATEX Directive 2014/34/EU compliant vacuum pumps offered by BINDER are designed for a gas
inlet temperature of 40 °C / 104°F max. Do NOT exceed this temperature. If the gas inlet temperature is
too high and then becomes even warmer by compression in the pump, the resulting temperature (of the
gas-solvent mixture inside the pump) could exceed the solvent’s temperature class and ignition tempera­ture.

DANGER

Exceeding the gas inlet temperature.

Exceeding the ignition temperature of the solvent.

Risk of ignition and explosion.

Damage to the vacuum pump.

Danger of death.

∅ Do NOT exceed a set-point temperature of 40 °C / 104 °F.

 With set-point temperature > 40 °C / 104 °F, take appropriate measures to cool down

the extracted vapor before it enters into to the vacuum pump.

1.5.3 Safety instructions on the charging material

The temperature class of the inner chamber according to IEC 60079-14 can be T1, T2, or T3. Only intro­duce substances with an ignition temperature that is higher than 135 °C / 275°F. You can use a solvent
which would form an explosive mixture with air under normal conditions.

This chamber is not suitable to dry substances with an ignition temperature below 135 °C / 275°F. Sub­stances falling under ignition group IIC are not permitted (e.g. carbon disulfide, hydrogen).

DANGER

Inappropriate charging material.

Explosion hazard.

Danger of death.

∅ Do NOT introduce any substance with an ignition temperature below 135 °C / 275 °F

into the oven.

∅ Do NOT introduce hazardous dusts or fibrous materials, which tend towards exother-

Danger of death.

∅ The ignition temperature of the contained solvents must NEVER be reached. For safety

reasons, you must provide a safety gap.

If the following precautions are not followed, the vapors resulting from heating of the solvent can ignite on
the hot walls of the inner chamber.

Required measures:

• The maximum drying temperature is a result of the lowest ignition temperature of the intro­duced solvent or solvent mixture. Take the ignition temperature from the safety specifica­tions of the solvent. Determine the maximum drying temperature according to the infor­mation panel “Temperature setting” (chap. 2.5) on the chamber
temperature when presetting the set point on the RD3 temperature controller.

• Before starting the drying process, set the temperature safety device to the maximum al­lowed drying temperature according to the information panel “Temperature setting” (

2.5). This will ensure that even in the event of error or an incorrect increase of the tempera­ture set point on the RD3 controller the maximum permissible drying temperature is not ex-

1.6 Intended use

The VDL vacuum drying ovens are suitable for drying and heat treatment of solid or pulverized charging
material, as well as bulk material, using the supply of heat under vacuum.

During this process, the contained solvent may be able to form an explosive mixture with air under normal
conditions. Generation of an explosive atmosphere and its ignition are prevented in the VDL vacuum
drying ovens by various safety measures. The drying temperature with standard safety factor must lie
below the ignition temperature and below the sublimation point of the charging material.

The VDL vacuum drying oven is explicitly approved for drying of materials with unlimited amounts of or­ganic solvents. The VDL is equipped with an explosion-proof inner chamber.

The temperature class of the inner chamber according to IEC 60079-14 can be T1, T2, or T3. It depends
on the maximum operation temperature inside the oven. Depending on the ignition temperature of the
flammable substance, this temperature and can be adjustably set on the temperature safety device ac­cording to the “Temperature setting” information panel (chap. 2.5).

Insert only substances with an ignition temperature that is higher than 135 °C / 275 °F. The chamber is
not suitable to dry substances with an ignition temperature below 135 °C / 275 °F. Substances falling
under ignition group IIC are not permitted (e.g. carbon disulfide, hydrogen).

The VDL vacuum drying ovens are NOT suitable for the heat treatment of hazardous dusts or fibrous
materials, which tend towards exothermal decomposition, or for materials that come under the legal defi­nition of explosives. Such substances must not be introduced into the oven. Dangerous chemical reac­tions must not occur during the drying process.

VDL vacuum drying ovens are not suitable for use in conjunction with explosive dust atmospheres or
hybrid mixtures.

Do not use the week program timer when using explosive substances.

Other applications are not approved.

The chambers are not classified as medical devices as defined by the Medical Device Directive
93/42/EEC.

Following the instructions in this operating manual and conducting regular maintenance work
(chap. 16) are part of the intended use.

The charging material shall not contain any corrosive ingredients that may damage the ma­chine components made of stainless steel and aluminum. Such ingredients include in particu­lar acids and halides. Any corrosive damage caused by such ingredients is excluded from
liability by BINDER GmbH.

2. Description of the equipment

The VDL vacuum drying oven has been inspected by the TÜV Product Service GmbH in accordance with
all safety-relevant guidelines and bears the TÜV-Mark P mark. Consequently, it is also expressly ap­proved for drying materials with unlimited quantities of organic solvents.

The regular model is equipped with an explosion proof inner chamber. The Ex classification of inner
chamber according to ATEX Directive 2014/34/EU is

explosion protection on the type plate determines the classification.

Maximum temperature of the inner surfaces: 320 °C / 608°F.

The temperature class of the inner chamber acc. to IEC 60079-14: depends on the setting of the temper­ature safety device and can be T1, T2 or T3. The temperature class of the entire chamber equals the
temperature class of the inner chamber.

All functions of the multifunctional program control can be set simply and conveniently via the easy to
understand function keypad of the RD3 temperature program controller. This controller is equipped with
touch function keys and a digital display and permits exact temperature setting and programming tem­perature cycles. The VDL provides almost unlimited possibilities of adapting to individual customer re­quirements based upon extensive programming options and on the real time clock of the controller.

II -/3G c IIB T3-T1 Gc X. The description of

The inner chamber is made of especially corrosion resistant stainless steel V4A (German material no.

1.4404 2B, US equivalent AISI 316L) micro-polished. The rack holder and all of the chamber's vacuum
connections and valves are made of especially corrosion resistant stainless steel V4A (German material
no. 1.4571, US equivalent AISI 316Ti). The housing is RAL 7035 powder-coated. All corners and edges
are also completely coated. When operating the chamber at temperatures above 150 °C / 302°F, the
impact of the oxygen in the air may cause discoloration of the metallic surfaces (yellowish-brown or blue)
by natural oxidation processes. These colorations are harmless and will in no way impair the function or
quality of the chamber.

The vacuum expansion racks allow for low-loss heat transfer to the material. The strong tension causes
the racks to fit tightly against the interior wall and their large-surface contact area ensures rapid and ef­fective heat transfer.

The vacuum drying ovens in the APT.line™ are jacket-heated. The APT.line™ preheating chamber tech­nique ensures a completely homogeneous jacket temperature, ensuring uniform heat transfer into the
inner chamber. The low-loss heat transfer to the material uses the patented aluminum vacuum expansion
racks (or optionally available in stainless steel V4A, 1.4571). The elastic-mounted safety glass window
reliably compensates any overpressure or explosions that may occur. The additional polycarbonate panel
ensures proven and effective splinter protection in the event of an implosion.

All VDL chambers provide an inert gas connection, a compressed air connection for sweeping the area
for electrical equipment, and a measuring connection serving to connect a measuring access port.

The VDL vacuum drying oven is equipped with a serial interface RS 422 for computer communication,
e.g. via the communication software APT-COM™ 3 DataControlSystem (option, chap.15.6). For further
options, see chap. 19.3.

All installable items, such as racks and rack holders, can be easily removed. The completely smooth
inner chamber with its rounded corners and internally welded seams is easy to clean.

The minimum working temperature of the VDL vacuum drying oven is approx. 15 °C / 27 °F above room
temperature. The maximum temperature is 200 °C / 392°F.

2.1 Safety equipment

• Pressure control device

The VDL vacuum drying oven is equipped with a pressure control device with atmospheric pressure
compensation and has a set switch point of 125 ± 25 mbar / 3.69 ± 0.74 inHg). In the event of mal­function, some procedures would become an ignition source. Due to monitoring by the pressure con­trol device such actions will only initiate if the pressure in the drying chamber is not higher than 125 ±
25 mbar / 3.69 ± 0.74 inHg.

The heating is released when a vacuum of 125 ± 25 mbar / 3.69 ± 0.74 inHg) or below is
obtained. It will activate only then.

• Safety device class 2

This safety device protects the VDL vacuum drying oven, its environment and the charging material
against impermissible excess temperatures. When correctly set to the maximum permissible drying
temperature it prevents exceeding the maximum drying temperature in case of a fault (chap. 12).

• Sweeping the area for electrical equipment and the preheating chamber with compressed air

The area for electrical equipment and the preheating chamber are protected against penetration of
explosive atmosphere by a technical ventilation system (1.8 bar overpressure). This is monitored by a
pressure sensor with a fixed switching threshold. Pressure loss results in turning off the entire oven.
This reliably prevents explosive atmosphere to reach electrical or electronic parts of the VDL safety
vacuum drying oven (protection against solvent-containing ambient air).

4. Installation and connections

4.1 Vacuum expansion racks

The low-loss heat transfer to the material occurs via the pa-

stainless steel as an option). The strong tension causes the
racks to fit tightly against the interior wall and their large­surface contact area ensures rapid and effective heat transfer.

The removable rack holders allow for easy positioning.

You can also remove the expansion racks for easy cleaning.
Do not remove them too often in order to prevent wear.

Figure 12: Using the expansion racks

• Pushing the locking lever: The expansion rack is released and can be removed.

• Pulling the locking lever: The expansion rack is pressed against the inner chamber walls.

Following each new tightening of an expansion rack, check that the lateral parts of the rack fit
closely over their whole surface to the inner chamber wall. This is necessary in order to en­sure the specified temperature exactitude.

Invalid calibration.

∅ Do NOT change between aluminum and stainless steel racks

 Use the delivered expansion racks only

VDL (E2.1) 05/2016 page 30/108

4.2 Vacuum connection

Always connect the VDL vacuum drying oven to a vacuum pump or to a domestic vacuum system. For
this purpose, the vacuum connection (13) with small flange DN16 must be connected to the back of the
chamber at the top with the vacuum pump or domestic vacuum system via a vacuum suction hose. For
connecting to the chamber, BINDER recommends the connection kits VP4 (Art. no. 8012-0621) or VP5
(Art. no. 8012-0622), (chap. 15.1).

With the option “stainless steel tubing” between the vacuum oven and vacuum module, the vacuum con­nection is already located inside the vacuum module.

Vacuum pumps with a suction capacity of 1-30 m³/h are suitable for the VDL vacuum drying
oven. Permissible end vacuum: 10

For use of vacuum pumps in the European Union, note the following points:

• Units that will be operated in potentially explosive areas have to meet the requirements of ATEX Di-

rective 2014/34/EU.

• If combustible solvent will be introduced into the inner chamber, the vacuum pump must be construct-

ed in a suitable explosion-proof manner. The mixtures extracted from the drying chamber must be car­ried away making sure that there is no danger by ignition of these atmospheres. Otherwise use flame
arresters.

Follow the safety instructions of the pump manufacturer.

In case of an explosion, the flame may be suctioned into the in-house vacuum system and result in fur­ther explosions.

For installing a flame arrester, please contact the BINDER INDIVIDUAL team.

In the event of an error, sparking in the pump motor or the switching elements, electrostatic discharges,
as well as hot pump parts can ignite solvent vapors. Minimize this risk by using an ATEX Directive
2014/34/EU compliant vacuum pump suitable for suction from Zone 0 or 1 and, if appropriate, from the
zone of its installation site.

DANGER

Ignition of emerging solvent vapors due to sparking in the pump motor or the
switching elements, electrostatic discharges, hot pump parts.

Explosion hazard.

Danger of death.

 Use only suitable, explosion-proof pumps

 Operate the pump in a stationary position and secure it so it is immobile.

 Install a fixed and conductive suction line to the vacuum connection (13).

 Install a fixed and conductive exhaust pipe in case it may conduct ignitable solvent

concentrations. This should be avoided by sufficient solvent condensation e.g., in an
exhaust waste vapor condenser

 When using ATEX Directive 2014/34/EU non-compliant pumps: Provide a current-

dependent, delayed protective device for the pump (for the triggering time of this pro­tective device, see the manufacturer’s specifications). The protective and monitoring
device must not be able to independently turn on again or be released.

 When using ATEX Directive 2014/34/EU non-compliant pumps: Install the switch gear

box outside the hazardous area or provide it with explosion protection.

 Assure that there is equipotential bonding between the pump housing and the housing

of the VDL vacuum drying oven via the connected equipment grounding conductors of
both units.

The ATEX Directive 2014/34/EU compliant pumps offered by BINDER provide an integral
protective device.

The ATEX Directive 2014/34/EU compliant pumps offered by BINDER provide an integral

Make sure that the vacuum source is designed for a gas inlet temperature corresponding to
the used drying temperature, or take appropriate measures to cool down the extracted vapor
before it enters into the vacuum source.

The ATEX Directive 2014/34/EU compliant vacuum pumps offered by BINDER are designed for a
gas inlet temperature of 40 °C / 104°F max. Do NOT exceed this temperature. If the gas inlet tempera-

ture is too high and then becomes even warmer by compression in the pump, the resulting temperature
(of the gas-solvent mixture inside the pump) could exceed the solvent’s temperature class and ignition
temperature.

Connect the inert gas supply to the inert gas connection (adapter with hose olive diameter 8 mm / 0.31 in)
via a pressure reducer. Screw the enclosed adapter with hose olive on the thread (11) at the chamber
rear. Set the pressure reducer to a pressure slightly above ambient pressure. Make sure that the pres­sure reducer will open. Do not alter this setting in order to avoid perturbation inside the oven and the re­lease of large quantities of inert gas after flooding the VDL.

Turbulence of the charging material.

∅ Do NOT modify the atmospheric pressure setting.

4.4 Compressed air / inert gas connection for sweeping the area for electrical equipment

The compressed air flows through the area for electrical equipment as well the preheating chamber,
which prevents a possible concentration of a solvent-containing atmosphere in the area for electrical
equipment. You can alternatively connect inert gas or nitrogen to the compressed air connection. Use
only dry gas.

In order to avoid that any oil coming from the compressed-air piping enters the vacuum drying oven, the
compressor of the compressed air system must be equipped with an oil separator, or the compressed air
system must be constructed oil-free. The condensate separator of the compressed air connection sepa­rates water and soil from the compressed-air piping, thus leading to compressed air quality class 4 acc.
to ISO 8573-1. However, it does not prevent oil penetrating from the compressed air system, e.g. the
compressed air compressor, into the compressed-air piping. The condensate separator is equipped with
a manual condensate outlet (chap. 16.1).

air unit must be connected on the right side of the chamber
(hose olive ∅ 8 mm) to a compressed air line (compressed air
system) or to an inert gas supply. There must be an overpres­sure of at least 1.5 bar / 44.3 inHg in the supply network. The
maximally permitted pressure is 7 bar / 206.7 inHg.

Immediately after connecting the compressed air or inert gas
supply, the area for electrical equipment of the oven will be
swept at 5 liters per minute. This air or inert gas quantity is used
and then released into the surrounding atmosphere permanent­ly;

should be equipped with a stop valve that can be used to cut off
the gas supply, after having operated the drying oven.

If solvent-containing air penetrates the electrical area of the chamber, explosions may result.

Solvent-containing air penetrating the electrical area of the chamber.
Explosion hazard.

VDL (E2.1) 05/2016 page 34/108

∅ Do NOT take the air for the compressed air supply from explosive atmospheres.

If the chamber is not connected to the compressed air supply, or if the specified overpressure
is not reached, it is impossible to start the VDL vacuum drying oven.

The compressed air connection is preset at the factory. Do NOT change the setting. In deliv­ery condition of the oven, this setting is protected by a cover with seal.

If the seal is broken, please inform BINDER Service to have the setting checked and to rein­stall the cover with seal.

4.5 Electrical connection

• The VDL vacuum drying oven comes with a fixed power connection cable that has a length of 1800

mm / 5.9 ft. and a shockproof plug. The socket must also provide a protective conductor.

• Chamber fuse 10 Amp

• Power supply voltage 230 V (1N~) ± 10 %, 50/60 Hz

• Prior to connection and start-up, check the power supply voltage. Compare the values to the specified

data located on the chamber’s type plate (left side of the chamber, bottom right-hand, chap. 1.4).

• We recommend the use of a residual current circuit breaker.

• When connecting, please observe the regulations specified by the local electricity supply company as

well as the VDE directives (for Germany)

• Pollution degree (acc. to IEC 61010-1): 2

• Over-voltage category (acc. to IEC 61010-1): II

CAUTION

Danger of incorrect power supply voltage.
Damage to the equipment.

 Check the power supply voltage before connection and start-up.
 Compare the power supply voltage with the data indicated on the type plate.

DANGER

Solvent-containing air penetrating and concentration in the electrical area of the
chamber.

Explosion hazard.

 Before turning on the chamber via the key switch (1), sweep the area for electrical

equipment at least 15 minutes with compressed air or inert gas. Sweeping the area for
electrical equipment must take place during the entire operation, as otherwise the VDL
vacuum drying oven will shut off at all poles.

After connecting the supply lines (chap 4) and checking all safety instructions and conditions of installa­tion and safe operation, turn on the chamber via the key switch (1):

• Position 0: Oven is not operating

No consumption of compressed air or inert gas in the area for electrical equipment. If the fine dosage
valve (6) is open, inert gas may be used and can reach the ambient air.

• Position I: Oven is operating

If no indication appears in the display of the program controller RD3, the compressed air sup­ply is probably not properly connected.

Warming chambers may release odors in the first few days after commissioning. This is not a quality de­fect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for one
day and in a well-ventilated location.

5.1 Settings at the RD3 program controller

After turning the chamber on with the key switch (1) the controller is in Normal Display / Fixed value op­eration mode.

Depending on the temperature value entered before, LED (7a) is lit if the heating is active, or no LED is lit
if the actual temperature is equal to or above the set-point.

8. Program editor

8.1 Selecting between set-point ramp and set-point step

You can program various kinds of temperature transitions. In the user level (chap. 10) you can select
between the settings “Ramp” (default setting) and “Step”.

Setting “Ramp” allows programming all kinds of temperature transitions.

With setting “Step” the controller will equilibrate only to constant temperatures; programming
ramps is no longer possible.

Switching between settings “Ramp” and “Step” will influence all programs. Please note that
this can cause the time courses of existing programs to change significantly.

8.1.1 Programming with setting “Ramp” (default setting)

Set-points always refer to the start of a program section, i.e., at the beginning of each program section,
the entered set-point is reached. During program section operation, the temperature gradually passes to
the set-point entered for the subsequent program section.

You can program all kinds of temperature transitions by the appropriate design of the program section
timing:

• Gradual temperature changes “set-point ramp“

The set-point gradually moves from one set-point to the one of the following program section during a
given interval. The actual temperature value (X) follows the continually moving set-point (W) at any
time.

Temperature ramps can be programmed in order to extend the heating up times. This may be neces­sary in order to avoid temperature stresses in the material during the heating up phase. Heating up
times can be considerably slowed down by the use of temperature ramps.

• Program sections with constant temperature

The initial values of two subsequent program sections are identical; therefore the temperature remains
constant during the whole time of the first program section.

• Sudden temperature changes “set-point step”

Steps are temperature changes (ramps) that occur during a very short interval. Two program sections
with an identical set-point are followed by a section with a different set-point. If the duration of this
transitional program section is very short (minimum entry 1 min), the temperature change will proceed
rapidly in the minimum amount of time.

8.1.3 General notes on programming temperature transitions

When exceeding the tolerance limits set in the user level (chap. 10), the program is interrupted until the
actual temperature value returns to within the tolerance range. During this program interruption, the LED
(7d) flashes. Therefore, the duration of the program may be extended due to the programming of toler­ances

The programming is saved even in case of a power failure or after turning off the chamber.

Solvents and the resulting vapors can ignite at excessive drying temperatures.

DANGER

Excess drying temperature.

Ignition and explosion hazard.

 Determine the maximum drying temperature in relation to the ignition temperature of

the solvent according to the information panel “Temperature setting” (chap. 2.5). Do
NOT exceed this temperature when presetting the set point on the RD3 temperature
controller.

 In the case of solvent mixtures, use the ignition temperature of the material with the

lowest ignition temperature.

 Before starting the drying process, set the temperature safety device (chap. 12) to the

permitted maximum drying temperature according to the information panel “Tempera­ture setting” (chap. 2.5).

 The heating is only released when a vacuum of 125 ± 25 mbar / 3.69 ± 0.74 inHg) or

below is reached. Only then should you start the program.

After program rundown the controller returns to fixed value operation showing Normal Display and equili­brates to the temperature value previously entered in fixed value entry mode.

Before starting the program, check the set-point value entered in fixed value entry mode.
After program rundown temperature will equilibrate to this value.

Deactivate the week program timer (factory setting, setting in the user level, chap. 10) before
starting a program.

8.2 Set-point entry for program operation

From Normal Display, press down button X/W for 5 sec to access the program editor. Then enter the set­points one after the other in all program sections of a selected program.

You can enter two programs with up to 10 sections each or one program with up to 20 sections (setting in
the user level, chap. 10).

In order to avoid incorrect programming, we recommend entering the values of the program course into a
table (template in chap. 8.3).

they will now replace the preceding sections, i.e., S04 is now called S03 etc.

Deletion leads to overwriting the section by the following one. It is therefore not possible to temporarily
inactivate a program section. To enter a section later to a program, all the sections following the new one
must be entered again.

“EXIT”

or wait 120 sec

9. Program start level

Before starting the program, check the set-point entered in Fixed value operation mode. After end of the
program, the temperature will equilibrate to this value. This value must NOT exceed the maximum per­missible drying temperature of a solvent contained in the drying material.

DANGER

Exceeding the ignition temperature of a solvent after the program ends.

Risk of fire and explosion.

Danger of death.

∅ Set-point of Fixed value operation must NEVER reach the ignition temperature of a

contained solvent. For safety reasons, always ensure that there is a safety margin
(chap. 2.5).

 Check the set-point of Fixed value operation and if necessary adapt it acc. to the tem-

perature setting information panel (chap. 2.5).

After the program ends, the temperature will equilibrate to the set-point entered in Fixed value operation
mode. If the week program timer is active, another set-point (SP2) may be targeted according to pro­gramming. Too high temperatures can occur which exceed the maximum permissible drying temperature
of a solvent contained in the drying material. Deactivate the week program timer before starting the pro­gram (default setting, setting in the User level, chap. 10).

DANGER

Exceeding the ignition temperature of a solvent after the program ends.

Risk of fire and explosion.

Danger of death.

 Deactivate the week program timer before starting the program.

Then define the settings for the program course. Two parameters can be set:

• Program delay time, i.e. a defined time before a program starts. It can be entered with a precision of 1

minute, and its maximum value is 99.59 (99 h 59 min). If the value is 00.00, the program will start im­mediately.

• Number of program cycles, i.e. the desired number of program repeats. Values from 1 to 99 can be

entered. If the program is not going to be repeated, enter the value “0”. For indefinite repeats enter the
value “–1”. The program is repeated as a whole; it is not possible to repeat individual sections.

In the last step start the selected program. These steps must be carried out subsequently.

12. Safety device class 2 (DIN 12880:2007)

The temperature safety device protects the vacuum drying oven, its environment and the charging mate­rial from exceeding the maximum permissible temperature.

Please observe the DGUV guidelines 213-850 on safe working in laboratories (formerly BGI/GUV-I 850­0, BGR/GUV-R 120 or ZH 1/119, issued by the employers’ liability insurance association) (for Germany).

The temperature safety device only activates after the set-point has been reached once.

Set the safety-device to the maximally permitted drying temperature according to the information panel
“temperature setting” (chap. 2.5), to prevent exceeding the maximum drying temperature in case of a
default. In the event of a fault in the temperature controller, the safety device (2) permanently turns off
the vacuum drying oven. This status is reported visually by the indicator lamp (2a).

Check the operation of the safety device (2) by moving it slowly counter-clockwise until it is turned off.
The safety device cut-off is reported visually by the indicator lamp (2a).

Then release the safety device by pressing the reset button (2b), and turn on the VDL vacuum drying
oven as described previously.

Figure 16: Temperature safety device class 2

VDL (E2.1) 05/2016 page 68/108

• Turn the control knob (2) of the safety device using a coin to its

When the set point is reached, turn back the control knob (2) until

lamp (2a) lighting up identifies the trip point; and the

Function:

The safety device is functionally and electrically independent of the temperature control device and turns
off the chamber at all poles.

If you turn the control knob (2) to its end-stop (position 10) the safety device will protect the appliance. If
you set it to a temperature a little above the set-point temperature, it will protect the charging material.

If the safety device has turned off the oven, identifiable by the red alarm lamp (2a) lighting up, proceed as
follows:

• Disconnect the oven from the power supply

• Have an expert examine and rectify the cause of the fault

• Release the safety device by pressing the reset button (2b)

• Restart the oven as described in chap. 4.5.

Adjustment:

To check the response temperature of the safety device, turn on the chamber and set the desired set
point on the temperature controller.

The scale division from 1 to 10 corresponds to the temperature range from 30 °C / 86°F up to 320 °C /
608°F and serves as a setting aid.

end-stop (position 10) (chamber protection).

•
its trip point (turn it counter-clockwise) is reached.

• The red alarm
reset button (2b) pops out.

• The optimum setting of the safety device is obtained by turning the
knob clockwise by approx. one graduation mark on the scale.

• Push the reset button (2b) in again.

Figure 17: Setting the safety
device class 2

The chamber is only active when the reset button (2b) is pushed in.

When the safety device responds, the red alarm lamp (2a) illuminates, the reset button (2b) pops out, and
the oven is turned off permanently at all poles.

Check the setting regularly and adjust it following changes of the set-point or charge.

Function check:

Check the temperature safety device class 2 at appropriate intervals for its functionality. It is recommend­ed that the authorized operating personnel should perform such a check, e.g., before starting a longer
work procedure.

Example: A substance with an ignition temperature of 160 °C shall be dried.

The maximum allowed drying temperature is 85 °C according to the information panel
“Temperature setting” at the front of the chamber (chap. 2.5). Set the temperature safety
device to a temperature of 85 °C max.

Also, the setting on the controller RD3 must not exceed this value.

According to IEC/CEI 60079-14 this chamber is not designated for the temperature classes T4, T5, and
T6. Introduce only substances with an ignition temperature which is higher than 135 °C / 275°F.

VDL (E2.1) 05/2016 page 69/108

This chamber is not suitable to dry substances with an ignition temperature below 135 °C / 275°F.

DANGER

Explosion hazard.

Danger of death.

∅ Do NOT introduce any substance with an ignition temperature #135 °C / 275°F into the

oven.

13. Reference measurements. Checking the temperature in the inner chamber

The controller display was adjusted in the factory to the temperature in the center of the usable volume
(chap. 19.1). The sensor probe of the reference measuring device was connected firmly to an expansion
rack positioned in the middle of the chamber.

Checking the controller display

• Conduct the reference sensor into the inner chamber through the measuring port (15). The port must

be largely vacuum tight to enable a typical operation vacuum for the calibration. For a high vacuum,
use a measuring access port (option). At low vacuum, a silicone plug with a hole for the sensor wire is
sufficient.

• Fix the sensor to the center of an expansion rack in the middle of the useable volume with adhesive

aluminum tape or thermal conductive paste to ensure sufficient thermal conductivity.

• Perform the measurement in a thermally stable condition with 3 expansion racks and empty oven.

• Equilibrating time: at least 12 hours.

Checking the spatial temperature exactitude

• Fix at least 9 sensor probes on 3 racks with adhesive aluminum tape or thermal conductive paste to

ensure sufficient thermal conductivity

• The distance of the sensor probes to all inner chamber walls must be at least 10% of the correspond-

ing inner chamber dimension (see DIN 12880).

• Perform the measurement in a thermally stable condition with 3 expansion racks and empty oven.

• Response time: at least 12 hours.

Do NOT use the temperature probe of the reference measurement device without any contact
to the expansion rack, i.e., do NOT measure vacuum values!

In case the temperature probe is a thermo element, mount it so it is electrically insulated from
the rack.

If you note an excessive divergence between the controller and reference temperatures, please contact
BINDER Service to calibrate the temperature controller.

14. Commissioning the vacuum

With regard to operation, please observe the DGUV guidelines 213-850 on safe working in laboratories
(formerly BGI/GUV-I 850-0, BGR/GUV-R 120 or ZH 1/119, issued by the employers’ liability insurance
association) (for Germany).

Starting situation: The vacuum source is connected and ready for operation.

For the vacuum module with chemical membrane pump option, see chap. 15.3.

VDL (E2.1) 05/2016 page 70/108

• Turn on the vacuum pump.

14.1 Evacuation

• Close the aeration valve (5) and the fine dosing valve for inert gas (6).

• Turn the lever of the vacuum shut off valve (8) to

the “ON” position (valve open).

• Monitor the internal pressure on the pressure

display (3). The analog manometer displays the
running evaporation respectively the end of the
drying procedure. The scale of the manometer (3)
refers to an ideal ambient pressure of 1013 mbar
/ 29.9 inHg. Tolerance: 50 mbar / 37.5 mm Hg
(Torr) / 1.5 inHg (2.5% of the final scale value +
reading precision).

• When the desired end vacuum is obtained, turn

the VDL vacuum shutoff valve (8) to the “OFF”
position (valve closed). The reached vacuum is

Figure 18: Manometer display

now maintained.

The permissible end vacuum is 10-2 mbar / 0.0003 inHg.

As long as there is a vacuum, never try to open the oven by force.

14.2 Breaking the vacuum (flooding with ambient air)

When the drying procedure is complete, the vacuum in the inner container is broken (flooded).

• Open aeration valve (5) and fine dosing valve for inert gas (6)

• As soon as aeration valve (5) is open, fresh air is sucked in through the fresh air connection (12).

When the fine dosing valve for inert gas (6) is open, fresh air is sucked in through the inert gas con­nection (11).

Fresh air is introduced into the lower part of the rear panel of the inner chamber where it is evenly distrib­uted in the inner chamber. This supply of fresh air by under-flooding prevents turbulence of pulverized
drying material.

14.3 Operation with inert gas

When operating the VDL vacuum drying oven with inert gas, correctly follow the technical ventilation
measures, as described in the DGUV guidelines 213-850 on safe working in laboratories (formerly
BGI/GUV-I 850-0, BGR/GUV-R 120 or ZH 1/119, issued by the employers’ liability insurance association)
(for Germany).

During operation with inert gas, the chamber is supplied with an oxygen displacing gas (e.g. N
gases in high concentrations are hazardous to health. They are colorless and almost odorless and there­fore practically imperceptible. Inhalation of inert gases can cause drowsiness up to respiratory arrest.

valve (6).

Install a pressure reducer for inert gas operation. Set the pressure reducer to a pressure slightly above
ambient pressure. Ensure that the pressure reducer will open. Do not change this setting in order to avoid
perturbation inside the oven and release of big quantities of inert gas after flooding the VDL.

Following evacuation, an inert gas, e.g., nitrogen, is led into the inner chamber via the fine dosing valve
for inert gas (6), until pressure compensation with the atmosphere occurs. Depending on the individual
application, you can perform a second evacuation and repeat the inert gas flooding.

When the inert gas fine dosing valve is open, a maximum of approx. 0.6 m³/h gas flows into the inner
chamber. The introduction of inert gas by under-flooding in the lower region of the inner chamber rear
wall and the extraction at the inner chamber ceiling allow an effective inert gas flushing.

Inappropriate execution of the pump connection can lead to the risk of explosion.

DANGER

Inappropriate pump connection.

Risk of ignition and explosion.

Danger of death.

 It is important to observe the pump manufacturer’s instructions regarding correct con-

nection and commissioning.

 Observe the safety advice of chap. 1.5.

Extracted vapors or the occasionally used inert gas can endanger health and/or have a corrosive effect
on the oven and pump.

WARNING

Release of extracted vapors.

Danger of injury.

Damage to the oven and pump by corrosion.

 Remove the extracted vapors and, if appropriate, the inert gas from the module via a

suitable conduit into e.g., a fume extractor facility.

 Directly connect the conduit to the corresponding pump outlets.

Confirm that the vacuum source is designed for a gas inlet temperature corresponding to the
used drying temperature, or take appropriate measures to cool down the extracted vapor be­fore its entry into the vacuum source.

A gas inlet temperature of 40 °C / 104°F maximum must NOT be exceeded. If the gas inlet tempera­ture is too high and then becomes even warmer by compression in the pump, the resulting temperature
(of the gas-solvent mixture inside the pump) could exceed the solvent’s temperature class and ignition
temperature.

DANGER

Exceeding the gas inlet temperature.

Exceeding the ignition temperature of the solvent.

Risk of ignition and explosion.

Damage to the vacuum pump.

Danger of death.

∅ Do NOT exceed a set-point temperature of 40 °C / 104°F.

 With set-point temperature > 40 °C / 104°F, take appropriate measures to cool down

the extracted vapor before its entry in the vacuum pump.

Defining the zone of the installation site of the vacuum pump (guideline 1999/92/EC)

If the pump module is defined as Zone 1, the operating chamber of the vacuum pump must be swept with
inert gas. A flow of at least 1 liter per minute (without pressure) is needed. For Zone 2 or without any
zone sweeping with inert gas is not needed. In addition to sweeping with inert gas, in case of condensing
media, you can connect a gas ballast in order to avoid condensation.

Installation of the supplied vacuum pump

• The vacuum drying oven is mounted onto the vacuum module as described in the mounting instruc-

tions Art. no. 7001-0137.

• The suction line is installed to the vacuum module as described in the mounting instructions Art. no.

7001-0137.

• When the pump is removed from the original packaging, place it in the vacuum module.

• Connect the pre-installed suction line to the vacuum pump inlet at the suction-side small flange con-

nection located at the top of the condensate flask.

• Connect a conduit that is suitable for removing the extracted vapors from the module, onto the pres-

sure-side connection of the vacuum pump (hose olive on the top-back of the emission condenser).

• Guide the end of the conduit into an exhaust air system, which is explosion-proof constructed in con-

sideration of any possible residual solvent contents. The operator must check if an explosive atmos­phere may be present at the pump exit or at the exhaust waste vapor condenser. For this purpose,
use a calculation of the solvent’s partial pressure at the set-up coolant temperature of the exhaust
waste vapor condenser and compare it to the explosion limits of the pumped solvent. The exhaust
solvent concentration should be minimized by selecting the most appropriate condensation tempera­ture for the solvent at the refrigeration plant that can be connected to the exhaust waste vapor con­denser. The pumped-out gases at the pump exit or the exhaust waste vapor condenser must be re­moved in a controlled manner and according to applicable security regulations. If there is any possibil­ity that an explosive mixture could still exist, the exhaust must be removed through antistatic conduits
and disposed of according to the valid regulations of explosion protection.

• The electrical connection is established at the pump’s connector box. This must be carried out accord-

ing to the original user manual of the pump manufacturer and to EN 60079-14. In addition, the zone
that has been defined by the user for the installation site of the pump must be correctly observed.
Equipotential bonding between the pump housing and the housing of the VDL vacuum drying oven
must be assured by the connected equipment grounding conductors of both units.

Inappropriate execution of the pump connection can lead to the risk of explosion.

DANGER

Inappropriate pump connection.

Risk of ignition and explosion.

Danger of death.

 It is obligatory to follow the instructions of the pump manufacturer regarding correct

connection and commissioning.

 Observe the safety advice as in chap. 1.5.

Extracted vapors or the occasionally used inert gas can endanger health. They can also have a corrosive
effect on the oven and pump.

VDL (E2.1) 05/2016 page 77/108

You can connect a laboratory cooling system to the emission condenser of the vacuum pumps

WARNING

Release of extracted vapors.

Danger of injury.

Damage to oven and pump by corrosion.

 Remove the extracted vapors and, if appropriate, the inert gas from the module via a

suitable conduit into e.g., a fume extractor facility.

 Directly connect the conduit to the corresponding pump outlets.

VP4 or VP5.

To operate the chemical membrane pumps VP4 (MZ2C EX) or VP5 (MD4C EX), please
refer to the enclosed pump manufacturer's operating manual.

Confirm that the vacuum source is designed for a gas inlet temperature corresponding to the
used drying temperature, or take appropriate measures to cool down the extracted vapor be­fore its entry into the vacuum source.

The ATEX Directive 2014/34/EU compliant vacuum pumps offered by BINDER are designed for a
gas inlet temperature of 40 °C / 104°F max. Do NOT exceed this temperature. If the gas inlet tempera-

ture is too high and then becomes even warmer by compression in the pump, the resulting temperature
(of the gas-solvent mixture inside the pump) could exceed the solvent’s temperature class and ignition
temperature.

DANGER

Exceeding the gas inlet temperature.

Exceeding the ignition temperature of the solvent.

Risk of ignition and explosion.

Damage to the vacuum pump.

Danger of death.

∅ Do NOT exceed a set-point temperature of 40 °C / 104°F.

 With set-point temperature > 40 °C / 104°F, take appropriate measures to cool down

the extracted vapor before its entry into the vacuum pump.

The maximum permissible ambient temperature of the vacuum pumps delivered by BINDER is 40 °C /
104°F.

15.4 Additional measuring channel for digital object temperature display with flexible Pt 100 temperature sensor (option)

The object temperature display permits recording the object temperature directly on or in the drying mate­rial. The object temperature is measured via a flexible Pt100 sensor inside the inner chamber. The sen­sor needs to be in thermally conducting contact with the charging material. It can be plunged into humid
charging material up to the length of its protecting tube.

Assembly and connection of the object temperature recording

• Insert the Pt 100 temperature sensor from the rear through the measuring connection (15) into the

inner chamber.

• The 3 contacts of the Pt 100 sensor are conducted outside via a measuring access port. From there,

establish the connection to the DIN socket (14) at the top of the rear panel of the chamber marked
“Pt100”. For reasons of explosion protection, this electrical connection to the inner chamber is con­ducted via a triple internal safety barrier with a conducting-state voltage of 1.6 Volt maximum against
ground.

19. Technical description

19.1 Factory calibration and adjustment

This chamber was calibrated and adjusted in the factory. Calibration and adjustment were performed
using standardized test instructions, according to the QM DIN EN ISO 9001 system applied by BINDER
(certified since December 1996 by TÜV CERT). All test equipment used is subject to the administration of
measurement and test equipment that is also a constituent part of the BINDER QM DIN EN ISO 9001
systems. They are controlled and calibrated to a DKD-Standard at regular intervals.

Factory adjustment was done in the center of the usable volume and under vacuum conditions. The sen­sor is fixed in the middle of the expansion rack in a way ensuring good thermal conductivity (heat conduc­tion). Measuring is performed in equilibrated state.

CAUTION

Invalid calibration.

∅ Do NOT change between aluminum and stainless steel racks.

 Use the delivered expansion racks only.
