point temperature on the RET basic, the ETS-D immediately

and permanently turns off the separate circuit of the RET

basic.

The stirring function then continues to run at the speed that was

set before the malfunktion.

A 6-pin jack is located on the rear side of the instrument for connec-

ting the ETS-D, the contact thermometer or the contact plug. The

electronics of the instruments returns a test current that must flow

via connector pins 3 and 5 for the heating plate to heat up.

Safety contact thermometers

acc. to DIN 12 878 class 2 or acc. Gerstel are connected with a

three-wire cable, the test current flows through the contact ther-

mometer.

Safety function:

If the test current is interrupted because of e.g. breakage of contact

thermometer or falling out of the cable plug, the heating cuts off.

The required plug allocation is indicated on a reference plate

above the diode bushing.

Contact thermometer without safety circuit

acc. to DIN 12 878 class 0. The instrument only heats if the test

current circuit is closed by an electrical connection of the plug

pins 3 and 5.

2-wire connecting cables:

Connect plug pins 3 and 5 of the instrument plug.

3-wire connecting cables:

Here the test current circuit can also be produced in the terminal

head of the contact thermometer (connect plug pins 2 and 3).

A 3-wire cable with the required bridge is available (accessories).

Settigs

For the detailed instructions for settings and limit values, please

refer to the operating instructions for the instrument you are

connecting.

The desired average temperature can be adjustedon the ETS-

D or contact thermometer. In addition, a "MAXTEMP" can be

set for the ETS-D, in other words, a maximum average tem-

perature can be set for malfunctions in combination with the

RET basic. The required surface temperature of the heating

plate can be selected with the "Temp" dial.

Adjusting the "Temp" dial to the maximum adjustable temperatu-

re will result in the fastest possible heating time, but the average

temperature may fluctuate to values above the set-point tempera-

ture on the contact thermometer, for example. By adjusting the

"Temp" dial to approximately twice the set-point value (thus with

a set-point ot 60°C the Temp dial would be set to 120°C), you will

reach a good compromise between a fast heating time and overs-

hooting the set point.

If you adjust the Temp dial to exactly the set-point temperature,

the medium will not reach the set-point temperature, since some

loss of the heat will always occur between the heating plate and

the medium.

The maximum heating plate temperature can be adjusted will

the "Safe Temp" screw.
