4.2 Switching off

Press the key . The display turns off, only the green control light in the lower right corneris on (stand by). Disconnection from the mains is performed by switching off the mainsswitch, in case of longer setting out of operation or during the repair by pulling the plug of themains cable from the socket. The total unplugging from mains (in case of a long-term puttingout of operation or a maintenance) is achieved by pulling the service cord from a socket –see also chapter Pre-installation.

4.3 Setting-up required values of temperature, time-delayed switching-off,number of cycles, time-delayed switching-on.

1. Set preselection of program 1 or 2 or 3 by means of or . After depressing

or the control lamp of further program starts to flicker. This program will be activated

within ca. 5 sec, if no other button is depressed during this time. Setting by means of

or will cause the stop of the running cycle and starting a new cycle with the pre-selected parameters.

Setting-up cycle begins with setting required temperature,

2. Depress , indicator lamps 15, 16 (Fig.3) begin to flicker, by means of setrequired temperature in °C on the display

The lowest adjustable and displayable temperature interval is 1 °C. Indicator lamps of the segments flicker permanently.

3. By depressing change to the segment of setting the time-delayed switching-

off, by means of set required value in hours and minutes from 0 (symbol---)to 99 hrs 59 min on the display, indicator lamps 16, 17 (Fig.4) flicker.

4. By depressing change to the segment of setting the number of cycles and by

means of set the number of cycles from 1 up to 255 (more information onthe cycles see 4.4) - all indicator lamps flicker during setting up.

This function can be used with time-delayed switching-off ≠ 0 only. Set the possibility to select the cycles by means of the user'supporting function.

5. By depressing change to the segment of setting the time-delayed switching-

on and by means of set the required value in minutes from 0 up to 99 hrs 59min, indicator lamp 14 (Fig.3) flickers.

6. Start the program by double depressing (start of the program is announced by an acoustic signal), data on real temperature with time count-down flickers on the display during the phase of time-delayed switching on. The heating is switched on after

reaching the time of zero and the display shows the real temperature in the chamber. After reaching the required temperature



a) in case of setting the time-delayed switching-off, the chamber temperature with the settime count-down begins to flicker on the display

b) or in case of unlimited switching-off, the chamber temperature with the rising time flickeron the display.Permanently lighting indicator lamps give information on just active program segment.

7.Individual set values can be checked during the run of the program - by depressing

the required value is shown on the display, indicator lamps flicker, by another

depressing within 5 seconds you change to the next segment, in this way allsettings can be checked successively.

Original program continues if you use no control element within 5 seconds.

8. Similarly, during the course of the program, you can change the already set values,when

a) after setting the last value - time-delayed switching-on - you wait approximately 5seconds, the program continues with changed values from the point of interruption

b)after setting the value you start the program by double depressing , the programstarts with new values from the beginning.

4.5 List of the error messages

Err 1 - not calibrated (the service engineer performs compensation of measuring conduitsof the sensor).

Err 2 - freeErr 3 - freeErr 4 - Err 10 - HW error (report this event to the producer)

4.6 Protocol printingPrinting the protocol with the help of CITIZEN printer, type iDP 3110-24 RF-A.By setting the interval of the printer you determine the time intervals in which the actual valueof the temperature in the chamber will be printed. Magnitude of this interval is stated in theheading of the excerpt. Interval of the printer can be set on the display within: tmin = 1minute, tmax = 255 minutes ( 4 hours 15 minutes) by 1 minute.1. We start from the condition, when the display displays real value of the temperature.

Connect the printer to the hot air box by means of the cable with serial connector (RS-232C) into the socket for the printer (see Fig.4), the other end of the cable connect to theconnector in the rear part of the printer. Connect the printer to the mains by connectingthe connector of the adapter AC 230 V, 50 Hz, 0.1 A/DC 7 V,1.6 A into the socket in therear part of the printer and by pushing the adapter into the mains socket. Switch on theswitch on the right side of the printer. Indicator POWER and SEL start shining. Theprinter is in the ON-LINE mode and it prints in this mode only! If you want to feedthe paper, depress the key LF. This may be performed only in the OFF-LINEmode, i.e. after depressing the key SEL, when the indicator SEL stops shining.Re-depress the SEL key to restore the ON-LINE mode, indicator

2. According to par. Setting-up required values of temperature set the required intervalupwards or downwards



3. The printer prints the head containing the type of the unit, set temperature and selectedtime interval. Values of the following data are printed in one line under this heading:

time from starting the program and actual temperature in the chamber.4. Switching the print off is performed by setting the print interval to 0 (symbol ---).5. In case of change of set operation conditions of the oven or in case of change of print

interval a new heading will be printed (this is not valid when set interval is 0 (symbol---)).6. If the power supplying the apparatus fails , after the power recovery the printer prints the

sign Power recovery! and the actual temperature value. Time intervals start counting

immediately after power recovery. After switching-off and switching-on by means of again a new head is printed.

7. If the power supplying the printer fails or the printer is turned off, no message is printedafter turning the printer on again or after power recovery .

8. Setting of the DIP / switches of the printer: all four pins are in lower position OFF.

4.7 Safety thermostat function and setting

Safety thermostat serves to protect the thermal box, its surrounding and treated materialagainst inadmissible exceeding the set temperature (e.g. it prevents damage or destroying ofmaterial samples in case of a damage to the temperature regulator or unintentional setting ofhigher temperature in the chamber of the unit than respective sample is able to bear).

In case of correct setting, the safety thermostatswitches off at approximately by 5 °C up to10 °C, higher temperature than the temperature set on the regulator of the unit. Setting thethermostat:1. Press the external rotary ring of the thermostat towards the control panel and with

simultaneous slight pressure turn it to the right (clockwise) up to the limit position(maximum). The center with the knob turn together with the external ring.

2. Thermal box is heated up to required operation temperature and left to stabilize forapproximately 10 minutes at this temperature.

3. Then turn the ring slightly to the right and depress the key of the thermostat. A slight clickis heard and indicator safety thermostat stops shining. If the click is not to be heard andthe indicator does not stop shining turn the ring slightly more to the right and depress thekey again. Repeat this procedure as long as the indictor stops shining. Only in such caseis the thermostat set onto required temperature. If the unit is set to maximum temperatureturn the ring to the right to maximum according to item

4. Operation of the unit continues..

NOTICE:Used safety thermostatis of class 2 (according to EN 61010-2-010) - mark TWB. Whensurpassing set temperature in the chamber, the thermostat switches the heating bodies offand the indicatorsafety thermostat starts shining (the unit does not heat even if the indicatorheating shines). Even after the drop of the temperature below set limit of the protectionthermostat, heating remains switched off. It is necessary to depress the knob of the safetythermostatto restore the operation. Indicatorsafety thermostat stops shining.



4.8 Creation of vacuum in the chamber

Push the hose from the vacuum pump onto the end of the vacuum piping of the unit (Fig.2,position 11) which is accessible through the side cut-out in the superstructure. Connect themains cord of the vacuum pump into the socket in the shaft of the superstructure and switchthe pump on. Set the ball valve on the front panel of the superstructure into the position VACON. Value of vacuum begins to rise on the vacuometer in the front panel after several tens ofseconds (the needle valve and the door must be properly closed).

4.9 Sealing exchange and door settingTake the whole sealing off, begin in the middle bottom part.Fix the new sealing on the edge of the chamber, begin in the middle bottom part. Slam thesealing between the chamber and the outer cover.To check up the tighteness place a sheet of paper between the door and the chamber whenclosing the door. Pull it out slowly, you should feel a stronger resistance.The door is adjustable at four points (see Fig.12):Pins of the lock – on the left front part of the jacket – at the top and at the bottom: these pinscan be loosened by means of the lock nut and they can be adjusted forwards/backwards bymeans of the thread.Door hinge, lower: by loosening the screw M8 at the front on the right side of the foot it ispossible to adjust the door forwards/backwards in the horizontal direction.Door hinge, upper 2: after removing the cover of the extension part the screws M8 in thefront right corner become accessible. After loosening these screws the position of the doorcan be adjusted.Adjust the door so that when closed the rubber sealing of the chamber would fit to the sheetof the floating door along the whole perimeter. To check it up place a sheet of paper betweenthe sealing and the metal sheet of the floating door before it is closed, it is possible to takethe paper out against a small resistance.

11.2 Box „Vacustation“Serves for placing the vacuum pump MZ2C, resp. MD4C (event. another vacuum pump withappropriate dimensions) in the space of the box, the vacuum box Vacucell is placed on top ofit. Both elements are screwed together.

11.3 Chemically resistant vacuum pumpFor instance membrane vacuum pumps MZ2C (suction power cca 1.7 m3/h, achievablevacuum cca 9 mbar) and MD4C (suction power cca 3 m3/h, achievable vacuum cca 2 mbar)are recommended.

11.4 Separator and emission condenserThe separator of the gas/steam exhausted from the chamber is placed between the chamberand the pump (the separating has a favourable influence on the power of the vacuum pump),emission condenser with water cooler is placed on the pump outlet and reduces the amountof emissions of the exhausted gas/steam in the outer space. Both parts are made of glassand are fixed on the pump.

11.5 System of vacuum controlConsists of the part CVC II and an electromagnetic suction valve. It enables to keep theconstant value of vacuum in the chamber and to show the measured values on the displayCVC II. CVC II is placed separately outside the box Vacucell and the suction valve isinstalled in the extension part of Vacucell.
