11.1

Operation of the Internal Cooling Unit

®
• If the CERTOMAT Tplus is equipped with the optional
cooling unit, you need not care for condensate
produced during cooling operation. Existing
condensate will be evaporated internally in the
cabinet.
•
To avoid damages of the refrigerator an integrated
overheat protection permanently switches off the unit
if the temperature in the incubation room exceeds
+38.5 C.
11.2

Connection of External Equipment

At the rear side of the device the CERTOMAT® Tplus
has a 15-pin Sub-D socket for analog signal outputs
and a collective alarm contact.

11.2.1 Analog Exits (ANALOG OUT)

•
For the external registration of speeds and
temperatures, e. g. with a recorder, the
CERTOMAT® Tplus has analog signal exits (0 ... 10 V).
The conditions are as follows:
0 V corresponds to 0 rpm.
Speed:
10 V corresponds to 400 rpm.
0 V corresponds to 0 °C
Temperature:
10 V corresponds to 100 °C
The moving load at the voltage entries must not be
lower than 10 kΩ.

11.2.2 Collective Alarm

Via the 15-pin sub-D "ANALOG OUT" socket two
potential-free contacts are available on PIN 7/8/15
which can be used to externally register alarm
situations.
