Design und function

6.1 General information
Operation of the freezer is via the electronic control ST200 //logg with touchscreen. The interior temperature is
measured by a temperature sensor PT100.
6.2 Alarm
An independent alarm component monitors functioning of the freezer. A rechargeable battery is integrated into
the alarm. This enables functioning of the alarm independent of mains power for 72 hours. The battery is charged
automatically in normal operation.


We expressly point out that customers must devise an emergency plan in the case of freezer outage to
ensure continual cooling of the chilled/frozen material. FRYKA-Kältetechnik GmbH is not liable for damages
caused by defrosting of chilled/frozen material due to a unit defect.
6.3 Interfaces
6.4 Refrigeration unit
The refrigeration unit is composed of a completely hermetic compressor, which cools copper tubes that are
wound around the interior.
The refrigeration unit is switched on and off to control the temperature.
The refrigeration unit is air-cooled. Process heat is dissipated via a fin coil heat exchanger, which is force-
ventilated by ventilators.
The interfaces are at the mains power connection and marked correspondingly.
(1) The RJ45 jack serves for connecting the unit to an Ethernet.
(2) An external alarm system can be connected to a potential-free alarm contact via
the three individual jacks (black – red – black). The required plugs are included in
the scope of delivery.
(3) The interior temperature is output as voltage signal (100 mV/K) at the 3-pin jack.
An external temperature recording system can be connected.
Output signal: 0V = 0°C / -10V = -100°C
