1.0 DESCRIPTION OF THE CABINET
These cabinets are designed for the controlling of
4-8- or 12 valve gates.
1.1 PROGRAMMING
Programming a sequence is accomplished with
the integrated multi-lingual user interface. This
applies to both types of VGC cabinets (keyboard
an blue backlit LCD display), offering the following
features:
• Programming the actuation of the valve gates.
• Loading / Saving 8 sequence les.
• Manual actuation of the valve gates.
• Display cycle time.
• Display value of screw position.
Optional Limit Switches: It is possible to use
position sensors and display the valve gate pin
positions.
1.2 CONTROL
Actuation of 1 or 2 valve gates opening and closing
per cycle:
Each movement can be triggered using one of the
following signals :
• Timer function from injection start or hold start.
• Screw position in %, cm3or in mm.
1.3 SIGNALS COMING FROM THE
INJECTION MOLDING MACHINE
Injection Start Signal is required.
The others signals recomended listed below are
optional
• Injection Hold signal.
• Screw position signal.
Important Notice : It is required to connect at least
the injection start signal to program a sequence
based on time.
For connecting these signals, please refer to the
wiring diagram on Page 3.

INTRODUCTION
1. 5 SECURITY
a) Alarm output on open contact, activated in case of:
• Fault on hydraulic power pack (not used if no
external power pack).
• Fault on injection safety : at least one valve gate
must be programmed to the open position at
injection start.and during the hole injection
cycle.
• Fault on control card.
• Fault on valve gate pin position during the
injection cycle time (optional).
b) Input “from hydraulic power pack in “via
isolated dry set of contact:
• Indicates to controller that hydraulic pressure is
available for the valve gates.
• If the hydraulic power pack is not functioning the
controller will not allow the cycle to run.
c) Alarm input on isolated dry set of contact:
• Indicates to the controller that the injection molding
machine is currently under alarm.
• If this alarm is active the controller will not allow
the cycle to run.

as for security on hydraulic power pack (10 pins
10A female).
C: Connector for commands to valve gates,
voltage 24V DC, 1.5 Amps per valve gate
(32 pins 10A female).
D: Option : Connector for limit switches on valve
gates (32 pins 10A male).
E: Power supply cable inlet 3G2,5mm2 (Supply
voltage 230V AC 50/60Hz).
F: Fuse holder with fuse 16A on cabinet.
G: Circuit breaker 16A (switching cabinet on / off).
IMPORTANT NOTICE:
When connecting the signals from the press to
connector A on cabinet, it is recommended to split
0-10V signals and 0-24V signals. Use a cable with
shielded pairs, connect screw position with the
first pair and hold signal, injection signal and 0-24V
supply with the other pairs.
1.7 DIMENSIONS IN. (MM)
• Cabinet VGC Seq Valve Gate Control for 12
valve gates :
17” (431mm) L x H 8.5” (216mm) H x 18.5”
(470mm) D
1.8 FUSES AND CIRCUIT BREAKERS
• Fuse 16A type gI for cabinet (size 10x38 mm).
• Circuit breaker 16A.
• Fuses 6.3A on each control card (size 5x20 mm).
1.9 APPLICABLE STANDARDS
Cabinet VGC Sequential Valve Gate Control is
approved for the Specification CE 73/23 “Low
voltage” and fullfill the EN 61010-1 standards.
They also comply with the following standards:
Electrical noise industriel environnent : EN 50081-2
Electrical Noise Immunity in industrial
environment: EN50082-2
INTRODUCTION
There MUST be a plug on connector B. Use either a dummy plug,
or a plug that is using the features intended for Connector B.

2.0 STARTING UP
Plant power 230V AC 50/60 Hz Single Phases cable
supplied.
Make sure that all connections to the backside
of the cabinet are correct (command signal,
alarms….). Switch the cabinet on with the 16A
circuit breaker.
The following pages appear after 5 seconds :
Important Notice: When the cabinet VGC Seq Valve
Gate Control is not in service, the A connector on
the backside of the cabinet must be disconnected
in order not to interfere with the signals from the
injection machine.
2.1 CALIBRATION
For proper use of the controller with the injection
molding machine, it is required to calibrate the
screw travel first.
To access the calibration page, simply select the
SYST function on white background, validate and
then select the SCRCAL function.
Select SCRCAL to calibrate the screw travel.
The following page is displayed.
Validate the function CALIBR to enter the calibration
process from this page and enter the calibration
values one after the other by moving the screw on
the injection machine.From this point, the process
must be brought to the end.
Guiding messages for the operator
Notice: The machine number is important information
to enter and to confirm which machine the calibration
process has been done on the controller.
Please note that if this controller is moved to another
machine, it must be recalibrated if you wish to use
the screw position signal for programming.
All words preceded by “MES.“ are values read
from the injection machine.
All words preceded by “VAL. “ are inputs made by
the operator.

2.2 CONFIGURATION OF THE SYSTEM
The system configuration pages are to set up control
parameters (date, time, language, etc.) as well as
to set up injection related parameters such as closing
duration after injection signal, prolonging of the
injection signal, etc.
To access the configuration page, select the SYST
function shown on white background.
Press the Validate key.
The following is displayed: these are the machine
parameters.
Default Factory Settings
Command for closing is held to all valve gates
after the injection signal has dropped
This is the time between the command and the
moment position control of the pin is made
(valid if option is purchased)
Prolonging the duration of the injection signal
2.2.1 DURATION OF THE CLOSING
SIGNAL AT THE END OF THE INJECTION
CYCLE
This is the time the closing command is sent to all
valve gates when the control cabinet is switched
on or when the injection signal drops. The default
value is set at 1 second. Set 0 to disable this function.
2.2.2 DELAY BEFORE POSITION CONTROL
(OPTIONAL)
This is to set a response time between the
electrical command sent to the solenoid valve and
the confirmation of the pin position by the limit
switch.
2.2.3 PROLONGING OF INJECTION SIGNAL
This function extends the injection signal by a
certain time (t1) in order to command the valve
gates for a longer period of time. When set at
0, and as soon as the injection signal drops, a
command for closing is sent to all valve gates.
Using this function can delay the command
for closing by a certain time when the injection
signal drops. The delay is adjustable in 1/100 sec
(see graph 3.1). Valve gate commands can be
programmed during this time.
