4.7 SAFETY SYSTEM FUNCTION AND

SETTING

The safety system watches the exposure process

controlled by the control circuit. It also performs

the function of a safety thermostat and serves to

protect the temperature box, its surroundings and

the processed material against an inadmissible

excess of the set temperature (it will e.g. prevent

The temperature never reaches the required

value during the exposure cycle. Check whether

4.6 PROTOCOL PRINTING

DPT 6333 printer is recommended for the record

printing on the printer. Other printers may also be

used, e.g. CITIZEN, model iDP

3110-24 RF-A. Printing to a PC application

(Printer Archiv) is allowed as well.

4.6.1 INSTALLATION AND SETTING OF THE

PRINTER

DPT-6333-V24 does not require any microswitch

setting by the user.

Setting the DIP microswitches of the printer

CITIZEN iDP 3110:

all four pins are in the lower position OFF.

Setting the DIP microswitches of the printer

CITIZEN CBM 910:

OFF / ON / OFF / ON / OFF / ON / ON / OFF

(from the left to the right).

CBM 910II: OFF / ON / OFF / OFF / OFF / OFF

/ ON / OFF.

After the setting is changed, the printer must be

switched off and on either by the switch or by

disconnection from the power supply.

(A different type of the printer must be adjusted

with the help of the printer´s manual and the data

on the interface RS232 shown on the case.)

Connect the printer to the device by means of a

cable with serial connector (RS-232C). Connect

one end of the cable to the printer socket (see

Fig. 4) and the other one to the connector in the

rear part of the printer. Connect the printer to the

electric power mains by means of an adapter.

Some types require the switch on the right side

of the printer to be switched on. The indicators

POWER and SEL light up. The printer is in the

on-line mode. Paper is fed by pressing the LF

button (in the on-line mode only, i.e. after the SEL

button pressing – the SEL indicator turns off. To

renew the on-line mode, the SEL button must

be pressed – the SEL indicator lights up). The

printer can print in the on-line mode only!

Follow the chapter User Support Functions to set

the type of data from the COM output connector

(user mode U3) and the required print interval

(user mode U1).

By the printer interval setting you can determine

the time intervals of actual chamber temperature

in case of the temperature regulator damage, or

unintended setting of a higher temperature than

that tolerated by the sample in the unit chamber).

Supervision is performed both under the normal

operation and in a Stand By.

The safety system measures the temperature

independently at the same place like the

regulatory sensor and counts the time

independently. If the set maximum temperature

and period of time are exceeded, the safety

relay switches off the heating, indicates the error

VWDWHE\LWVLQGLFDWRUÀDVKLQJUHGDQGSDVVHV

the information about the error to the controlling

unit which then passes to the error regimen and

indicates the error.

To cancel the error by the user, hold X/W. The

controlling unit cancels the error state in the

safety system circuit. The device passes to a

break state in which parameters can be reset, or

you can let the chamber cool. The device is put

into operation by pressing ON/OFF.

4.7.1 CHANGE OF THE MAXIMUM VALUES

It is carried out in the user settings U6 and U8

– see the diagram of the safety system function

and the user settings description. Minimum

11.5 INDEPENDENT PT100 SENSOR

This is another additional sensor, freely

movable in the chamber. Temperature inside

the chamber or in the material can be measured

by means of it. The sensor leads are brought to

a vacuum-tight connector placed in a bush of

PPGLDPHWHU7KHÀH[LEOHVHQVRULVPRVWO\

used for the material temperature measurement

directly in the chamber.

This sensor is measured and calibrated in the

same way as the regulating sensor and its

value is also set off. It is shown on the display

(according to the setting in the user mode) in

regular intervals alternating with the regulating

sensor temperature display. It differs from

the regulating sensor by an apostrophe on the

highest digit. The exposure start (according to

the setting in the user mode) is also enabled

after reaching the preset temperature on this

sensor with a tolerance of – 0.25 °C. However,

the original condition must be met, i.e. the preset

temperature on the regulating sensor must be

reached with a tolerance of – 0.05 °C.

Good heat-conducting contact between the

sensor and the measured material must also be

ensured, especially under the vacuum conditions.

11.6 INDEPENDENT PRESSURE SENSOR

It is another additional sensor by means of which

pressure inside the chamber can be measured.

This sensor is measured and calibrated. It is

shown on the display (according to the setting

in the user mode) in regular intervals alternating

with the temperature display. It differs from

the temperature by an apostrophe on the highest

digit.
