5.1.2 Thermo contact temperature air-oil mix (TM)
Stops the machine if it reaches over 110ºC in the compressor drive, indicating the fault via the pilot light L1
of the electrical panel.
When the unit is working on full load, the correct operating temperature is 60 to 65ºC plus the ambient
temperature.
Maximum ambient temperature is considered to be between 40 and 45ºC, depending on the work
load.
It is not possible to restart the unit until the L3 pilot light goes out.
5.1.3
Hour counter (H)
Indicates the number of hours the unit has worked and serves for checking when maintenance and regular
servicing is due.
5.1.4 Hot wire
Protects the installation from short circuits in the electrical system. It is restarted manually. Regulation is set
at 20A.
5.1.5
Motor oil Pressure switch (P)
Measures the pressure of the oil in the motor and if this does not exceed a specific value, it stops cutting
power to the solenoid (SOL) and this is indicated in the L3 light on the electrical panel.
5.1.6
Temperature motor oil (T). Thermo contact
Stops the unit when the motor oil temperature is excessive. This is indicated by the L1 light on the electrical
panel.
5.1.7
Battery charge light.
Indicates that the battery charging system is working correctly. It should be off when the motor is working.
The L5 light on the panel should light up when the contact is activated and the motor is off. When the motor
starts up the L5 light should go off.
5.1.8
Excess air pressure
All the equipment has a safety valve (SV) located in the air-oil tank, tarred at a 10% more than the maximum
work pressure of the equipment, and able to evacuate all the flow produced by the compressor.
