Each instrument is provided with an output for remote display XR REP, which shows the temperature of
cabinets or goods.
•
The XB570L controller is provided with internal real time clock and can be connected to the XB07PR
printer. This means that a report, which includes all the main features of cycle, can be printed: start and
end of the cycle, length of the cycle, logging of the temperature of the cabinet and goods.
4. MOUNTING & INSTALLATION
Model XB570L is a controller for panel mounting: the cut out dimensions are 150x31 mm and it has to be
fixed with screws. The ambient operating temperature range is from 0.0 to 60°C. Avoid locations subject to
heavy vibration, corrosive gases or excessive dirt. The same warnings have to be applied to the probes.
Ensure enought ventilation around the instrument.
5. ELECTRICAL CONNECTIONS
The instruments are provided with a screw terminal block to connect cables with a cross section up to
2.5mm
2
for probes and digital input.
Spade on 6.3 mm heat-resistant wiring for supply and loads. Before connecting cables make sure the power
supply complies with the instrument’s requirements. Separate the input connection cables from the power
supply cables, from the outputs and the power connections.
Do not exceed the maximum current allowed
on each relay , in case of heavier loads, a suitable external relay has to be used.
The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. It is
recommended to place the thermostat probe away from air streams to correctly measure the average room
temperature. Place the defrost termination probe among the evaporator fins in the coldest place, where most
ice is formed, far from heaters and from the warmest place during defrost, to prevent premature defrost
termination.
