MasterCase is the system for the complete management of showcases.
MasterCase controls and manages the entire refrigeration unit, both electrically
and electronically. The use of power relays means that MasterCase does not require
an extra electrical panel, and can directly control the lights, defrost heaters,
fans and cooling actuators. MasterCase can be connected to a local network to
co-ordinate operations on a group of utilities.
The MasterCase series controllers can also directly manage
electronic expansion valves, which significantly improve the performance of
the refrigeration unit. In addition, the controllers can be connected to the
PlantVisor supervisory and remote management system, for saving and displaying
all the operating data from the case.
STRONG POINTS
Advantages of the range • Possibility of master/slave configuration for the control
of multiplexed cabinets (1 master + 5 slaves). This allows:
- synchronisation of defrosts;
- sharing of probes and control functions;
- downloading of the parameters from the master to the slaves.
• HACCP management function;
• fast programming using the hardware key;
• advanced functions for energy savings;
• reduction in assembly times (less components to be installed inside
the panel, less wiring required, etc.);
• possibility to manage an electronic expansion valve;
• up to 8 relay outputs and five programmable digital inputs;
• standard user terminals that can be installed at a distance of
up to ten metres.
User interface
The user interface is made up of the PST series and PGD0* terminals (the
latter for MasterCase2 only). The terminals can be connected “live”,
that is, with the instrument is on.
Energy savings
The use of the night-time set point, a series of smart defrost functions
and the electronic valve are just some of the functions that guarantee
significant energy savings.
Electronic valve MasterCase with the built-in driver can also
control the operation of a proportional electronic expansion valve with
stepper motor (version MGE0000020 and MC200N0B10). MasterCase2, moreover,
can directly manage a PWM on/off electronic expansion valve. In this way,
lower and more stable superheating values can be achieved, with higher
evaporating temperatures, allowing greater humidity levels and ensuring
a more constant temperature in the case and consequently better conservation
and higher quality of the products.
Product certification MasterCase series fitted with the standard Carel NTC probe is
compliant, as required by EC regulation 37/2005 of 12 January 2005, with
standard EN 13485 on thermometers for measuring the air temperature in
applications on units for the conservation and sale of refrigerated, frozen
and deep-frozen food and ice cream.
