2. Chamber description
The alternating climate cham ber MK / MKT is a s pecially developed precision cooling/warming cabinet f or
the domain of industr ial mat erial testing and environm ent sim ulation, with an unrivalled capacity, which far
exceeds the capabilities of norm al test cabinets, providing the ideal facilities for solving all the problems
which occur during material as well as ageing and stress tests.
The chambers ar e equipped with a multifunctional microproces sor display controller for temperature with
a digital display accurate to one-tenth of a degree. W ith its com prehensive progr am contr ol functions, the
display program controller MB2 perm its the high precision perf ormance of temperatur e cycles with rapid
heating up and cooling down phases.
The patented APT.line™ preheating cham ber and air conduction technology guarantees excellent spatial
temperature values for the total working area. T he chamber is equipped with a powerful refrigerating system permitting rapid cooling-down speeds. In addition, it provides almost unlim ited poss ibilities f or adapt ation to individual customer requirements based upon extensive programming options.
The high-quality housing insulation guarantees both a low noise mode of operation and a consistently low
housing temperature. T he inner chamber, the pre-heating cham ber and the interior side of the doors are
all made of stainless steel V2A (Germ an material no. 1.4301, US equivalent AISI 304). When operating
the chamber at temper atures above 150 °C / 302°F, the impact of the oxygen in the air may cause discoloration of the metallic surfac es (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 hous ing is RAL
7035 powder-coated. All corners and edges are also completely coated.
The efficient program controller is equipped with a m ultitude of operat ing functions , in addition to recorder
and alarm functions. Pr ogramming of test cycles is easily accomplished via the modern touchscreen display controller MB2 and is also pos sible directly with a computer via Intranet in connection with the APTCOM™ 4 Multi Management Software (option, chap. 20.1) . The chamber comes regularly equipped with
an Ethernet serial interface for com puter communication. In addition, the BINDER APT-COM™ 4 Multi
Management Software (option) perm its networking up to 100 chambers and connecting them to a PC for
controlling and programming, as well as rec or ding and repres enting temperature data. For further options,

5.4 Operating modes
The MB2 program controller operates in the following operating modes:
• Idle mode
The controller is not functional, i.e., there is no heating or refr igeration. The fan is off. The cham ber
approximates ambient values.
You can activate and deactivate this operating mode with the “Idle mode” control contact in Fixed value
operating mode (chap. 7.3), time program operation (chap. 9.7.3) and week program operation
(chap.10.6.5).
• Fixed value operating mode
The controller operates as a fixed-point controller, i.e., set-points can be defined, which are then m ai ntained until the next manual change (chap. 7.1).
• Timer program operation
Stopwatch function: during an entered duration the controller constantly equilibrates to the setpoints
entered in Fixed value operation mode.
• Time program operation
An entered time program is running. The controller offers 25 program memory places with 100 program sections each. The total number of program sections of all programs is unlimited
• Week program operation

5.7 Performance during and after power failures
During a power failure, all controller functions are shut down.
After the power returns, all f unctions return to the same status the cham ber had before power failure. .
The controller continues to function in the original operating mode it was in previously before the power
failure occurred.
• Performance after power failure in Idle mode
Control is deactivated
• Performance after power failure in Fixed value operation mode
All functions return to the same status the chamber had bef ore power failure. The set-points are immediately resumed.
• Performance after power failure during time program operation
The program is resum ed at the point where the interr uption occur red with the latest set -points r eached
during the program run.
• Performance after power failure during week program operation
The week program continues with the values corresponding to the current time.
Power failure and power return are noted in the event list (chap. 15.3).
If during power failure an alarm has occurr ed (tolerance range, saf ety controller, optional over/under tem-
perature safety device class 2), confirm the alarm. See chap. 11.3.
MK / MKT (E5) 03/2019 page 37/158
5.8 Performance when opening the door
When you open the door the fan starts running with minimum speed (30 %).
After 60 seconds from opening the door, heating, refrigeration, and fan turn off. The com pressor contin-
ues operating during 5 minutes without cooling function.
After closing the door, heating, refrigeration, and fan turn on again.
6. Start up
6.1 Turning on the chamber
After connecting the electrical supply (chap. 4), you can start up the chamber.
• MK 56: Turn on the m ain power switch (1) in the lateral control panel at least one hour bef ore operat-
ing the chamber.
• MK/M KT 115, 240, 720: Turn on the main power switch (1) in the lateral control panel and the rear
power switch (12) at least one hour before operating the chamber
The lit pilot lamp shows the chamber is ready for operation. When the chamber is turned on and yet the
controller display is dark, the display is in stand-by mode. Press on the touchscreen to activate it.
MK 56: The r efrigerating function is available only one hour after turning on the main power switch (1).
This is indicated by the notification “Preheating phase” in the controller display.
MK/MKT 115, 240, 720: The refr igerating function is available only one hour after turning on the main
power switch (1) and the rear power switch (12). This is indicated by the information message “Preheating
phase” in the controller display.
Warming chambers may release odors in the first few days after com miss ioning. This is not a quality defect. To r educe odors quickly we recomm end heating up the chamber to its nom inal temperature f or one
day and in a well-ventilated location.
For control reasons the refrigeration machine starts with a delay time. The refrigeration machine also turns off with a 5 minutes delay. This explains why the compressor may remain
operating also during positive temperature jumps.
MK / MKT (E5) 03/2019 page 38/158
6.2 Controller settings upon start up
The window “Language selection” enables the language selectio n , in case that it’s activated in the “Startup” menu. Afterwards occurs a request of the time zone and the temperature unit.
The controller will function in the operating mode, which was active before the last s hut-down. It controls
temperature in f ixed value operating m ode to the last enter ed values and in the program m ode to the set
points achieved beforehand.
Locked operation
Provided that the user administration has been activated by the assignment of pass words f or the diff erent
authorization types, the controller operation is first locked after turning on the unit, recognizable by the
closed lock icon in the header.
In the locked view the controller provides all display functions. No setting functions are available.
The setpoints are shaded (light grey) in normal display. Changing them by direct entry in the fixed value
operating mode is not possible. The f unctional icons for setpoint entry and program s tart in the footer are
without function.
After turning on the unit, user log-in is required to operate the controller (chap. 13.2)
Operation without user log-in / without password-protection
If the password f unction has been deactivated, af ter turning on the unit without user log-in there are those
controller functions available, which correspond to the highest authorization level without a password protection. There is no lock icon in the header.

9.7.2 Set-point ramp and set-point st ep
You can define the type of temperature transitions for each individual program section.
“Ramp” mode: Gradual changes of temperature
The set-point of a given program secti on functions as the sec tion’s star t tem perature. Dur ing the section’s
duration, the set-point gradually passes to the set-point of the subsequent program section. The actual
value follows the continually changing set-point.
If the last program sec tion is in “ramp” mode and the setpoint shall change within this section, then you
must program an additional section (with the shortest pos sible section duration) to provide the target temperature of the last program section. Other wise, the setpoint would remain constant during the section’s
duration.
Programming in the “ramp” mode allows all kinds of temperature transitions:
• Gradual changes of temperature
The setpoint changes its value gradually during the entered section duration. The act ual value follows
the continually moving set-point at any time.
• Program sections with constant temperature
The setpoints (initial values) of two subsequent pr ogram sections are identical; so the temperatur e re-
main constant during the entire duration of the first program section.
• Sudden changes of temperature
Steps can be programm ed in ramp mode as temperature changes (ramps) that occur during a very
short interval. If the duration of this transitional program section is very short (minimum entr y 1 sec),
the temperature change will proceed rapidly within the minimum amount of time.
“Step” mode: Sudden changes o f temperature
The set-point of any program section functions as the section’s target value. At the start of the pr ogram
section, the unit heats up or cools down the chamber with the maximum speed to reach the entered value;
and then it holds it for the remaining section time. Theref ore the set-point temperature remains constant
for the section’s duration. These changes occur rapidly within the minimum amount of time (minimum
entry: 1 second).
Programming in the “step” mode allows only two kinds of temperature transitions:
• Programming gradual changes of temperature (ramps) is impossible in the “step” mode
• Program sections with constant temperature
The setpoints (target values) of two subsequent program sections are identical; so the temperature
remain constant during the entire duration of the first program section.
• Sudden changes of temperature
The entered setpoint of the section is reac hed as fast as possible and then held cons tant for the re-
maining section duration.

9.7.3 Special controller functions via operat ion lines
You can define the switching state of up to 16 operation lines (control contacts ). They are used to activate
/ deactivate special controller functions.
• Operation line “Idle mode” activates / deactivates the operating mode “Idle mode”.
• Operation lines „Switching output 1“ up to „4“ can be us ed to turn on and off any equipment connected
to the zero-voltage switching outputs (DIN sockets (7) and (8) (option, chap. 19).
• Operation line “Compr. air dryer” serves to activate the compressed air dryer (option, chap. 20.6).
• Operation line “Com pressed air valve” serves to open the solenoid valve of the compress ed air con-
nection (for options compressed air connection, chap. 20.5, or compressed air dryer, chap. 20.6)
• Operation line “Anti-condensation protec tion” serves to switch the anti-condensation protection (chap.

9.7.5 Tolerance range
You can specify a temper atur e progr am tolerance range for eac h pr ogram section with different values for
the tolerance minimum and maximum. When the actual value exceeds the given threshold, the program is
interrupted. This is indicated on the display (see below). When the actual temperature is situated again
within the entered tolerance limits, the program automatically continues. Therefore, the duration of the
program may be extended due to the programming of tolerances.
Programming of tolerances may extend program duration.
An entry of “-99999” for the tolerance minim um means “minus inf inite” and an entry of “999999” for the
tolerance maximum means “plus infinite”. Entry of these values will never lead to program interruption.
The entry of “0” for the tolerance minimum and/or maximum deactivates the respective tolerance function.
When requesting rapid value transitions, we recommend not programming tolerance values in order to
enable the maximum heating-up or cooling-down speed.

band.
• Select the field “Tolerance band min” and enter the desired lower tolerance band value. Setting range: -
99999 to 99999. Confirm entry with Confirm icon. The controller returns to the section view.
• Select the field “Tolerance band max” and enter the desired upper tolerance band value. Setting range:
-99999 to 99999. Confirm entry with Confirm icon. The controller returns to the section view.
If the actual temperature value is outside the program tolerance range the whole program course is interrupted. During this program interruption time the controller equilibrates to the set-points of the current
section.
The screen header indicates “Progr am pause (tolerance band)”. The program runtim e indication flashes
and does not proceed any further.
When the actual temperature value is back within the entered program tolerance r ange, the program c ontinues automatically.

12. Temperature safety devices
12.1 Over temperature protective device (class 1)
The chamber is equipped with an internal temperature safety device, class 1 acc. to DIN 12880:2007. It
serves to protect the chamber and prevents dangerous conditions caused by major defects.
If the actual temperature exceeds the nominal temperature by approx. 20 °C, the over temperature protective device permanently turns off the cham ber. T he user c annot restar t the chamber again. T he protective
cut-off device is located internally. Only a service specialist can replace it. Therefore, please c ontact an
authorized service provider or BINDER Service.
12.2 Overtemperature safety controller class 2
The chambers ar e regularly equipped with an electronic overtemperature safety controller (temperature
safety device class 2 acc ording to DIN 12880:2007). The safety controller is functionally and electrically
independent of the temperat ure control system and serves to protec t the chamber, its environment and
the contents from exceeding the maximum permissible temperature.
With option temperature safety device class 3.3 (chap. 12.3), the safety controller is not used.
In this case it must be set to the maximum temperature.
Please observe the DGUV guidelines 213-850 on safe work ing in laboratories (for m erly BGI/GUV-I 850-0,
BGR/GUV-R 120 or ZH 1/119, issued by the employers’ liability insurance association) (for Germany).
When the entered s afety controller set-point is reached, t he overtemperature safety controller turns of f the
heating, fan, and refrigeration system. T his condition (state of alarm ) is indicated visually and additionally
with an audible alert if the buzzer is enabled (chap. 11.4). The alarm persists until the chamber cools
down below the configured safety controller setpoint and the alarm is manually reset.
Check the setting regularly and adjust it following changes of the set-point or charge.
The safety controller only activates after the set-point has been reached once.
12.2.1 Safety controller modes
You can select between “Limit (absolute)” and “Offset (relative)” safety controller mode
• Limit: Absolute maximum permitted temperature value
This setting off ers high safety as a defined temperature limit will not be exceeded. It is im portant to
adapt the safety controller set-point after each modification of the temperature set-point. Otherwise, the
limit could be too high to ensure ef ficient protec tion, or, in the opposite case, it could prevent the con-
troller from reaching an entered set-point outside the limit range.
• Offset: Maximum overtem perature above any active temperature set point. The maximum tempera-
ture changes internally and automatically with every set-point change.
This setting is recom mended for program operation. It is important to chec k the safety controller set-
point and safety controller m ode occasionally, as it does not offer a fix, independent lim it temperature
value, which would never be exceeded.

13. User management
13.1 Authorization levels and pass word protection
The available functions depend on the current authorization level “Master”, “Service”, “Admin” or “User”.
The authorization levels are hierarchical: Every authorization includes all functions of the next lower level.
“Master” authorization level
• Highest authorization level, only for developers
• Extensive authorization for controller operation and configuration, outputs/inputs, alarm settings, pa-
rameter sets and operating ring display
• All passwords can be changed in the “log out” submenu (chap. 13.3).
“Service” authorization level
• Authorization level only for BINDER service
• Extensive authorization for controller operation and configuration, access to service data
• The passwords f or “Service”, “Admin” and “User” author ization levels can be changed in the “log out”
submenu (chap. 13.3).
“Admin” authorization level
• Expert authorization level, for the administrator
• Authorization for controller configur ation and network settings and for operating those controller func-
tions required for operating the chamber. Restricted access to service data.
• Password (factory setting): “2”.
• The passwords f or “Admin” and “User” authorization levels can be changed in the “log out” subm enu
(chap. 13.3).
“User” authorization level
• Standard authorization level for the chamber operator
• Authorization for operating the controller functions required for operating the chamber.
• No authorization for controller configuration and network settings. The “Settings” and “Service” sub-
menus of the main menu are not available.
• Password (factory setting): “1”
• The password for the “User” authorization level can be changed in the “log out” submenu (chap. 13.3).
As soon as a password has been assigned for an authorization level, the access to this level and the related controller functions are only available after log-in with the appropriate password.
If for an authorization level no password is assigned, the related controller functions of this level are available for every user without login.
If passwords have been assigned for all authorization levels, access to the controller functions is locked
without login.
MK / MKT (E5) 03/2019 page 74/158
Operation after user login
At user login, the authorization level is selected
and confirmed by entering the respective password.
Following user login, controller operation is available, recognizable by the open-lock icon in the
header. The available controller functions correspond to the user’s authorization level.
Password protection acti vated for all levels: operation without user login is locke d
If passwords have been assigned for all authorization levels, the controller is locked without registration of a user.
As long as no user is registered, controller operation is locked, recognizable at the closed-lock icon
in the header. This requires that the user management has been activated by the assignment of
passwords for the individual authorization levels.
Password protection for at least one level deactivated: operation without user login is possible
If passwords have not been assigned for all authorization levels, after turning on the chamber
there are those controller functions available,
which correspond to the highest authorization
level without password protection.
No lock icon is shown in the display header.
User login is neither required nor possible.
To activate the password protection and user
login, perform new password assignment (chap.
13.5.3).

To check the authorization level of the user currently logged-in, select in Normal display the arrow far right
in the display header.
The information window shows date and time, the cont roller’s free memory space and under “Authorization” the authorization level of the current user.
If passwords have been assigned for all authorization levels, a user without login (password entry) has no
authorization. There are only viewing functions available.
Display when all authorization levels are password protected and no user has logged in:
No authorization level is displayed.
If passwords have been ass igned only for s ome of the authorization levels, a user without login (password
entry) has access to the functions of the highest authorization level without password protection.
Display when only some of the authorization levels are
password protected (example: no protection for the “User” and “Admin” levels) and no user has logged in:
The user’s effective authorization (due to lack of password protection) is shown.
Example: user with “Admin” authorization.
If passwords have been assigned for som e or all of the authorization levels, user login (password entry)
provides the authorization for the corresponding password-protected level.
Display when at least some of the authorization levels
are password protected and a user has logged in.
The user’s authorization (by password entry) is shown.
Example: user with “Admin” authorization.

The self-test func tion enables an autom ated chec k of the proper cham ber f unctioning as well as a target-
ed and reliable fault analysis. It is available with the “Master”, “Service”, and “Admin” authorization levels.
In this case, the chamber suc cessively undergoes various defined operating states, which serves to determine reproducible character istic values. These characterist ic values provide information on the performance and precision of the individual func tional systems of the chamber (e.g., heating, ref rigeration) of
the chamber.
The results of the self -test are stored in the service recorder of the controller. You can export them using
the controller’s USB interface and send them to BINDER Service (use function “Export service data” to
USB stick, chap. 14.6). BINDER Service will evaluate the data using an analyzing tool.
Activating the self-test mode
In order to allow an optimum comparison of the determined characteristic values with the
reference characteristic values, the ambient temperature should be in the range of +22 °C
+/- 3 °C / 71.6 °F +/- 5.4 °F.
