5.1 MACHINE SAFETY DEVICES
CAUTION!
It is forbidden to run the machine after inhibiting, changing or tampering with safety
devices the machine is fitted with.
Coldelite is NOT responsbile for any damage to persons and/or things if protections for
the operator and other machine safety devices have been inhibited, changed or tampered
with.
Following are safety systems the machine is fitted with:
THERMAL RELAYS
They sense anomalous inputs of beater motor and motocompressor; reaching the maximum
setting values causes the machine stop and activation of alarm system.
Before resetting, it is necessary to find out reason of relay tripping.
Thermal relay reset automatically.
PRESSURE SWITCH
Cooling system protection. It stops the cooling compressor if there is no water into the circuit.
Reset is automatic.
CAUTION
Too a long operation of the compressor or repeated stops and restartings means an
insufficient condensation; check its causes.
FUSES
They protect the electric circuit of controls against overloads.
When they trip and before replacing them, find out trouble causes and put remedy.
NOTE:
To identify values and characteristics of fuses, please see the machine wiring diagram.
NOTE:
Whenever a safety device trips, the machine gives a message on the display showing which
automatic device has tripped.
Such messages are to be found on page 5.
