When operating the sample holder flange beware of
the shape of the thermocouple cable.
Do NOT tear at the cable and prevent a complete
straightening of the cable.
For safe operation with sample spinner preserve a
minimum of four windings (3).
Before demounting the sample holder flange and
changing the sample holder disconnect the cable
from the sample holder at the bottom of the sample
holder flange (4).
4.4.3 Connection of Sample Spinner Motor
The motor of the sample spinner has to be connect-
ed to the connector "Sample Spinner" on the con-
nector box (Fig. 8 (4)).
4.4.4 Connection for Safety Circuit
At the rear of the HTK 1200N is a small safety
switch box for flange control and overheating pro-
tection. Connect the extension cable from the safety
switch box on the back of the HTK 1200N to the
connector "Flange Control" on the connector box
(
Fig. 8 (2)
).
4.5 Connecting CCU 1000 with a Com-
puter
The RS 232 serial port at the rear panel of
CCU 1000 allows you to connect the CCU 1000 to a
computer for remote control (see Fig. 10 (3)).
A null modem RS 232 cable is required to connect
the CCU 1000 to a PC.

NOTICE
According to EN60950 standards, the RS 232
serial interface represents a SELV circuit which
must therefore only be connected to SELV cir-
cuits.
