Tandem compressors with timed control unit. (fig. 17). 

5.8.1

 

.1 Fit the plug in the power socket (fig. 13) and turn the pressure switch to position 

“I” (ON). Turn the master power switch “A” on the control unit to position I – power On is 

signalled by white indicator-light “E” going on. 

5.8.2

 

.2 Turn switch “B” to start the compressor. 

5.8.2.1

 

.1 Pos. 1 pumping element n. 1 only is operating 

5.8.2.2

 

.2 Pos. 2 pumping element n. 2 only is operating 

5.8.2.3

 

.3 Pos. 3 both pumping elements are operating simultaneously, 

at staggered starting times. 

5.8.3

 

.3 The compressor is fully automatic, and is controlled by the pressure switch 

which stops it when tank pressure reaches maximum value and restarts it when it falls 

to  minimum value. 

 

 

The head/cylinder/delivery tube unit can reach high temperatures. Take care when working near 

these parts, and do not touch them to avoid possible burns (fig. 18 - 19). 

 

IMPORTANT 

The electro-compressors must be connected to a power socket protected by a suitable differential 

switch (thermal-breaker). The motor of GM-TR compressors is equipped with an automatic 

thermal breaker located inside the winding – this stops the compressor when motor temperature 

reaches excessively high values. 

If the breaker is tripped, the compressors restarts automatically after 10 to 15 minutes. The 

motors of compressor models VX are supplied with a manually resetting automatic amperometric 

thermal-breaker, located outside the terminal board cover. 

When the breaker is tripped, wait for a few minutes and then reset the breaker manually (fig. 20). 

The motors of the AB series compressors are supplied with a manually resetting amperometric 

thermal-breaker, located on the terminal board cover. When the breaker is tripped, wait for a few 

minutes and then reset the breaker manually (fig. 20). 

The safety device is automatic in three-phase and silent compressors. When the thermal-breaker is 

tripped, the pressure switch is released to “0” (OFF) position. 

Wait for a few minutes and return the pressure switch to “I” (ON) position (with the exception of 

models: AB 100/245-335 Three-phase - AB 150/ 245-335 Three-phase - AB 200/245-335 Three- 

phase). For compressors supplied with a control unit, the thermal-breaker is installed inside the 

control unit. When the thermal-breaker is tripped, observe the following procedure (fig. 22): 

 

Turn the switches on the control unit cover to position “0”, open the cover and press push- 

button 1 of the thermal-breaker. Close the cover of the control unit and restart the compressor, 

observing the operations described in the paragraph “Starting compressors with control unit”. 

The same instructions apply to compressors powered at 60 Hz.

 

 

5.9

 

Adjusting the operating pressure (fig. 23). 

5.9.1

 

.1 You do not have to use the maximum operating pressure at all times. On the 

contrary, the pneumatic tool being used often requires less pressure. On compressors 

supplied with a pressure reducer, operating pressure must be correctly adjusted. 

5.9.2

 

.2 Release the pressure reducer knob by pulling it up, adjust pressure to the 

required value by turning the knob clockwise to increase pressure and anti-clockwise to 

reduce it. 

5.9.3

 

.3 When you have obtained optimum pressure, lock the knob by pressing it 

downward (fig. 23). For pressure reducers equipped without a pressure gauge, the set 

pressure can be seen on the graduated scale located on the reducer body.
