V. INSTALLATION OF SENSORS, TYPES OF COVER SHELLS
1. For each type of the manufactured equipment a place for securing the sensors and the SCCB settings
should be determined experimentally. Absolutely do not change the fastening location nor the way
the sensors are secured nor modify SCCB settings without prior carrying out new tests relating to
temperature stabilization and equipment defrosting cycle !!!
2. Fastening of the chamber sensor must be done in such a way so that it does not get in contact with
food products and is not exposed to damage when cleaning the equipment. The sensor can be fixed
using a special plastic bracket. This solution causes fast (on/off time delays see VI p. and 5 and 7)
response of the sensor and the entire thermostat to the change in the air temperature in the unit. When
desired or necessary to slow down and "smooth" the time of sensor response to the temperature
changes we recommend to fix it to the metal part of the unit.
3. Fasten the evaporator sensor in the way to ensure maximum and good contact with the evaporator
lamella and in place where ice remains for the longest time during defrosting. Its fastening should
prevent it from being pushed out by the growing ice. The sensors, wherever possible, should be fixed
vertically so that the cable exits from the bottom of the sensor.
4. Sensor cables can be shortened or extended in any way, however with respect to the following
rules:
- do not cut the sensor cable at a section smaller than 0.5 m. From the case
- it is not recommended to extend the sensor cable to more than 20 m.
- THE SENSOR CABLES CAN BE CONNECTED TO THE TERMINALS OF THE
ACTUATOR SENSORS IN ANY WAY!!!
(in the same way as you connect the plug to the ~230V outlet)
- for cable extension we recommend using OMY 2x0.5 mm type conductor
- connect the extended cables with great care, by soldering each pair of cores and put thermally
shrinkable jackets on them. Then apply water-proof silicone on the joint and clamp one more
thermally shrinkable jacket on it.
- whiten the ends of the conductors connected to SCCB with tin
VI. GENERAL OPERATION PRINCIPLES
A - General Information
1. After connecting power supply the device performs a 3-second initialising procedure during which the
display shows two dots for a second, controller software release for another second, and two dots
again. During that time none of the connected appliances are switched.
2. After completion of the above initialising procedure, the middle segments of the display show two
dashes indicating “powered” condition – if the device was not powered before!!! The device is started
