UNIT SPECIFICATION
Basic functions
The control unit is equipped with the "temperature control" and "time switch" basic functions. The unit can set an operating temperature of up to 250 °C and switching times of between 0:01 and 99:00 hours.
Refer to STARTING UP WITH BASIC FUNCTIONS for information about the commands for the basic functions.
Added-feature programming functions, fixed programs
The control unit is capable of running heating process programs with fixed, preselected parameters from a database. The program segment and the parameters are stored in the
database.
The fixed program contains a maximum of four program segments and a status command.
Only one fixed program can be stored. In the programmed controller function one arbitrary difined program can be stored independend of the fixed program.

Each program segment, P I - P 4, is assigned to a typical temperature / time response. 10
selectable sets of parameters are permanently stored in the database for each program
segment. These sets of parameters can be assigned within the program.
A status command is provided as the fifth program segment. This determines the subsequent action with the program selected from the fixed program memory:
Program on standby, do not execute yet = Select " P. o F "
Program on standby, wait for program start = Select " P. o n "
Delete program from memory completely = Select " P. r E "
The program memory is erased on delivery. If the operator interrogates the program segments,
"Parameter set off" appears in the display panel = e.g. " P. I - ".
When compiling a program, selecting "parameter set off" within the selected program segment causes the control unit to bypass this segment for the fixed program function.
The selected program always runs from program segment P I. n to program segment P 4. n.
If program segment P 3. n is combined with program segment P 4. n, the heating and blower are only switched off following termination of segment P 4. n.
If a program is interrupted and started again, the sequence commences at segment P I. n.
The previously selected operating temperature cannot be changed once the program has started.
The heating is switched off in the event of a power failure (> 20 ms) with subsequent restoration of the power supply, the temperature inside the unit is displayed as a flashing value and the program must be started again.

Programmed controller function
The programmed controller function enables the arbitrary definition of temperature / time processes.
You may select up to 9 program segments. Operating temperature and period can be selected for each segment.
Termination commands
A termination command can be selected as the last program segment beginning at the second segment. The termination command determines the function to be performed by the unit after running through the program.
There are three optional termination commands:
" hold " = Once the program has terminated, the operating temperature set for the last program segment is maintaned until a new operating temperature has been selected.
" StOP " = Once the program has terminated, the heating is switched off until the "stop" command is cancelled.
" CYCL " = Once the program has terminated, it returns to the beginning and is repeated continuously until the "CYCL" command is cancelled.
A termination command must always be entered at the end of every program.

Programmed controller function
No, the oven cannot be used to dry or heat substances that may release combustible gases or vapors into the atmosphere. It is also unsuitable for the heat treatment of combustible dusts or fibrous materials.
You must use a draft breaker to connect the oven to an extraction system. All flue ducts must be made of fireproof materials and thermally insulated.
The oven is equipped with an electronic upper-limit cut-out device (TWB) of protection class 2 as defined by DIN 12 880 Part 1. It is electrically and functionally independent of the temperature control system. If the unit heating system malfunctions, the TWB will shut down the unit heating across all poles as soon as the temperature exceeds the preset value.
The fixed program contains a maximum of four program segments and a status command. Each program segment is assigned to a typical temperature / time response. 10 selectable sets of parameters are permanently stored in the database for each program segment.
The programmed controller function enables the arbitrary definition of temperature / time processes. You may select up to 9 program segments. Operating temperature and period can be selected for each segment.
Where can I find the electrical schematic for the T6P oven?
The electrical schematic for the T6P oven is available as an approved spare part or accessory. You can locate the order numbers for the circuit diagrams in the 'Approved spare parts / accessories' section of the manual. For 1/PE AC, 230 V/208V, the order number is 50 041 987. For 1/PE AC, 120 V, the order number is 50 040 640.
What is the recommended relative humidity for operating the device?
The recommended relative humidity for operation is between 60 and 70%, avoiding condensation. The maximum relative humidity is 80% for temperatures up to 31°C, decreasing linearly to 50% relative humidity at 40°C.
