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.

4.0 INSTALLATION FOR 115 VAC
WARNING: IMPORTANT INFORMATION
Danger! Disconnect all voltage before inspecting or servicing the BLOWBACK
CONTROLLER. Only properly trained, qualified technicians should operate or service
the BLOWBACK CONTROLLER.
Dangerous Voltage! Do not put your finger or any object in the program SD
card slot. If the power supply is not connected properly, the slot for the SD card
may carry voltage. The SD card cover must be in place at all times. NOTE: the
SD card is optional and is not needed for normal operation.
All national and local electrical, building, and safety codes need to be followed. Proper
grounding of all equipment is important. Check the electrical wiring schematic for wiring
numbers and details.
Wiring for 115 VAC
1. Mount the LOGO control box in a secure location.
1. Remove screws (item number 3 in drawing BC-1-11 allowing the cover plate to be
removed.
3. Remove the cover plate (item number 2 in drawing).
4. Connect wire nut (wire number 1 in drawing) to the 115 VAC hot power supply
located inside the main MCS control panel.
Note: There are two wires numbered 2. One is for connecting to the 115 VAC
neutral in the main MCS control panel and the other one is for connecting to the
blowback solenoid valve.
5. Connect wire nut (wire number 2 in drawing) to the neutral conductor located inside the
main MCS control panel.
6. Connect wire nut (wire number 2 in drawing) to the blowback solenoid located at the
vacuum receiver
7. Connect wire nut (wire number 4 in drawing) to the blowback solenoid located at the
vacuum receiver.
8. Connect wire nut (wire number 8 in drawing) to the 115 VAC hot station valve output
requiring blowback.
9. Connect wire nuts (wire numbers 3, MCSMAT Demand in drawing) in series with the
demand level switch of the station requiring blowback.

6.0 OPERATION
5.1 Control Description
The BC-1 blowback control is connected to an MCS main control to add a blowback feature,
when required. The BC-1 employs a mini-PLC Control. The control is housed in a rugged
enclosure and is factory programmed for functions related to vacuum loading.
NOTE: The user may adjust certain parameters of the control to fine tune their loader’s
operation, but changing settings other than those listed can damage control operation.
5.2 Preset Controller Values
The BC-1 controller is preset at the factory with the following values.

5.3 Changing Controller Values
Press the OFF/ON switch for the BLOWBACK CONTROLLER to the “ON” position.
Allow a few seconds for the LOGO! controller to start up.
Using the instruction on the controller under TO CHANGE SETTINGS:
Adjust the number of blowback pulses by changing the BB/Cnt parameter values in the
“Settings” menu of the controller to achieve the desired blowback pulsing for that station.
When the station loading signal is de-energized to the LOGO unit and the OFF/ON switch
is in the ON position, the blowback solenoid will be energized for the number of pulses
set in the BB/Cnt parameter value. Once the blowback cycle is complete, the contact on
the blowback controller wired in series with the station demand level switch would close
allowing the station to begin loading again if the demand level switch were also closed.
The BB/Gap timer controls the OFF time between pulses and the BB/Pls timer controls
the ON time of the pulse, these timers are set at 1.0 and 0.5 seconds respectively and
should not require further adjustment.
