• Interface protocol (Protocol)
“Modbus”: The chamber interface can be used as a communication interface to connect it to a
computer. This serves to control the chamber by the APT-COM™ 4 Multi Management Software. It is
possible to read and write the values of all parameters.
“Printer”: A protocol printer for data printouts can be connected to the chamber interface. The printer
regularly protocols the actual temperature value with fixed formatting and with adjustable print intervals.
In both cases an interface converter RS 422 / RS 232 is used.
• Print interval (Prt.-Inv.)
Setting of the print interval in minutes. Function is available only if setting “Printer” has been selected in
the previous menu point.
• Display illumination (Disp.LED)
Selection between continuous display illumination and limited illumination that will automatically go off
300 sec after the last entry.
• Program type selection (PrgSelec)
Select between entry of two programs with up to 10 sections each or of one program with up to 20
sections.
When changing from 2 programs to 1 program or vice-versa, existing programs are
deleted in the program editor.
• Maximum section duration (Prg.Time)
The maximum length of an individual program section can be set to either 99 hs 59 min or to 999 hs 59
min. This setting is then valid for all program sections.
When changing the maximum duration setting, pre-existing programs will be deleted in the
program editor.
• Set-point programming type (Setp.sim)
Selection between “Ramp” and “Step”. With setting “Step” selected, you don’t need to program the
transition section in the Program Editor.
If you select setting “step”, the controller will equilibrate only to constant temperatures;
programming ramps becomes impossible.
A change between settings “ramp” and “step” will influence all programs. Note that
significant change in time courses may arise in existing programs.
• Tolerance limit range (Tol.band)
Entry of a tolerance limit value in °C. Program operation: If the actual value of temperature exceeds the
set-point of a program section by more than the entered tolerance limit value, the program is halted
(LED (3d) flashing) until the actual temperature value is again within the tolerance range.
Entry of “0” means tolerance limits are off.
• Activating or inactivating the week program timer (Prog.Clk)
„Inactive“: The week program timer is switched off (factory setting). The corresponding setting menu
(chap. 7) is not visible, nor is set-point 2 in the Fixed value entry mode (chap. 6).
„Active“: The week program timer is activated.
