Section II - Description

Electrical System

A diagram of the electrical system is 

shown in the parts manual sent with the 

compressor.  A wiring diagram is also 

included in the control panel on all Quincy 

QGV compressors.

 notiCe!

Due to continuing product improvements 

and updates, it is suggested that the 

wiring diagram included in the control 

panel  be  used  when  servicing  the 

electrical control.

Standard drive motors are open drip 

proof 800 RPM with a maximum ambient 

temperature rating of 04°F.  They are not 

suitable for salt laden, corrosive, dirty, wet 

or explosive environments.
The QGV series compressors utilize 460V 

incoming power through a magnetic 

starter.  A transformer in the control panel 

reduces this voltage to 20 VAC for various 

electronic controls on the unit.  These 

controls include the pressure transducer, 

high air temperature safety switch and 

probe, solenoid valve and various indicator 

lights.  
Other incoming line voltages are available 

as options.  The compressor is provided 

with a NEMA  enclosure.  Optional panels 

include NEMA 4.
Air-cooled models utilize a second 

magnetic starter for protection of the fluid 

cooler fan motor.  This starter is connected 

to the compressor starter through an 

interlock which insures the fan motor is 

operating with the compressor motor.  If 

the fan motor starter trips out for any 

reason, the compressor unit will shut down.

Danger!

High  voltage  could  cause  death  or 

serious  injury.    Disconnect  all  power 

supplies before opening the electrical 

enclosure or servicing.

Safety Sensors

Two high air temperature (HAT) sensors 

are standard on QGV units.  These sensors 

protect the unit by sensing unusually high 

temperatures and shutting the unit down.  

One is located in the discharge line from 

the compressor to the air/ fluid reservoir.  

The second is located in the top of the 

air/fluid reservoir.  These sensors are set to 

trip at approximately 225°F.  The sensors 

are nonadjustable.

Warning!

Never  remove,  bypass  or  tamper 

with  the  safety  HAT  switch.    Failure 

to  provide  this  safety  feature  could 

cause  death  or  serious  injury  and 

property damage.  If the compressor 

is shutting down due to high discharge 

temperature, contact a qualified service 

technician immediately.
