ITEMS
•
Condenser fan speed variator
To maintain condensing within set limits, the condenser fan speeds must be adjusted
according to condensing pressure. This device must be connected to the high-pressure
circuit. The instructions for use are attached to the documentation supplied with the machine.
•
Minimum pressure switch
This operates by stopping the machine when the pressure in the suction circuit drops to below
its set value. This occurs as the result of a fault.
•
Crankcase heater
This is used to heat up the compressor crankcase before start up and to keep it warm during
stoppage. The heat produced by the heater causes any refrigerant in a liquid state inside the
compressor to evaporate.
•
Voltage monitor
This cuts off power to the Blocksystem in the event that mains voltage is out of the set range.
Resetting is automatic.
•
Remote control system
Link-up module to monitor, remote control and record data using a remote supervisory
system.
•
Thermomagnetic circuit breaker
This device protects the Blocksystem against overloads or short circuits.
•
Panel for plug-in version (thickness 100mm)
By adding a plug, it is possible to change the assembly method from the standard saddle
version to the plug-in version (mounting instructions will be sent together with the insulating
plug-in panel).
