BLOWBACK CONTROLLER
115 VOLTS AC
24 VDC

2.0 SPECIFICATIONS

Novatec Blowback Controllers are designed to control the blowback solenoid of a vacuum
receiver. Compressed air from the blowback solenoid pulses the pellet screen to remove
plastic particles.
The blowback controller is used along with the main MCS panel when blowback is
necessary. The MCS supplies power to the blowback controller as well as a station-loading
signal that is wired in parallel to the station "T" valve. When the MCS de-energizes the
station "T" valve the blowback controller pulses the blowback solenoid for a preset number of
times. While the solenoid is pulsing, a contact on the blowback controller wired in series with
the station demand level switch opens preventing the station from loading until the blowback
cycle is complete. Once blowback is finished the contact closes allowing the receiver to
begin filling once the demand level switch closes as well.

3.0 UNPACKING AND INSPECTION

Novatec Blowback Controllers are shipped complete with all controls for automatic operation.
Completely inspect the unit for damage. The units are packaged securely, but vibration and
mishandling during transit can cause damage.
