1 Introduction
1.1 About This Manual
The ALPS Flex Pitch DUO Multi-Moving head leak tester provides high speed leak testing of a
wide range of container types including shingling, reverse-taper, and small containers which are
traditionally dicult to test. The Flex Pitch DUO has a smaller footprint to perform leak testing on
an existing conveyor line, requiring no conveyor line modications. The Flex Pitch DUO has built
in exibility with 2 test heads for a variety of container sizes up to 4” diameter and 10” Height. This
makes the Flex Pitch DUO ideal to leak test dicult containers. The Flex Pitch DUO Multi-Moving
head leak tester provides tool-less adjustments and no formatted parts to change, making quick
container changeovers. The Flex Pitch DUO uses servo motors and linear slide combination coupled
with an encoder (mounted to the top of the conveyor) to track the conveyor movement and speed.
As molded containers enter the machine, the Multi-Moving test heads locate and leak test each
container. After the test is completed, good containers pass through the machine, and defective
containers are ejected from the conveyor line with a reason displayed on the HMI.
A single electrical cabinet is installed on the backside of the machine containing the AC power
circuits, servo motor drives, DC power supplies, power contactors, and main disconnect. The control
system features a multi-channel PLC and color touch screen interface with an intuitive, icon-based
menu structure. Standard features include an integrated Self-Test feature for each station.
1.2 Software
Installation of any new or modication of existing software into the FlexPitch DUO machine not
approved by Air Logic Power Systems LLC may adversely aect the operation or performance of the
machine and possibly void the warranty and or service agreements. Please consult Air Logic Power
Systems Service Department prior to installing or modifying existing software on this machine.
1.3 System Modications
Mechanical or electrical modications not approved by Air Logic Power Systems LLC to the FlexPitch
DUO system may also void the warranty and/or service agreements. Please contact the Air Logic
Power Systems Sales or Service Department 1-800-325-8717 for approval or assistance with any
machine modications.

2.3 Safety: Warning Labels and Descriptions
Safety is always critical. The ALPS FlexPitch machine is equipped with a full complement of warning
decals and labels. A standard series of warning and caution labels are in place to inform the
operator of certain hazards relative to the function of this machine. Please observe these warnings.
2.4 Danger! Arc, Shock, and Flash Hazard:
The potential for serious or fatal injury exists. Located on the outer door surface of the High-
Voltage Control enclosure. Do not open to explore or attempt to aect repairs in this area. In case
of breakdown, initiate Lock-Out Tag-Out procedures to secure the machine. Notify authorized
personnel.
2.5 Risk of Hot Surfaces Hazard
This symbol can be found in areas where a potential burn hazard exists. FlexPitch servo motors have
hot surfaces. Do not touch motor surfaces while in operation or after being recently shut down.
2.6 Lock Out Tag Out
This decal appears prominently next to the main power switch on the side of the High Voltage
Control cabinet at the rear of the machine. Lock-out and tag-out procedures are covered in the
service and maintenance manual.

2.7 Warning! Watch Your Hands and Fingers
This warning is seen on the front of the discharge chute. Do not thrust your hand up this chute while
the machine is operating. Contact with moving container material poses a slight to moderate threat
of injury.
2.8 Danger! Do not operate Without Guards in Place
This warning is located on the lower front portion and rear plexiglass guard of the machine. It
cautions the operator not to attempt to operate this machine without a plexiglass guard panel in
place. The potential for severe injury exists while the machine is operating. Please keep hands, long
hair, low hanging jewelry, and loose clothing away from the moving parts.
2.9 Danger! Starts Automatically
This warning is displayed on all plexiglass doors as a warning that the machine starts and stops
automatically as a function of its normal operating scheme.

target pressure is reached, the pressure loss must not exceed the maximum percentage amount
allowed during the allotted time or the container will be rejected

7 Theory of Operations
7.1 Leak Test Operations
Figure 1: Peak Pressure Chart
7.2 Pressure Test
Untested containers are transferred from line conveyor to the FlexPitch. When the FlexPitch begins to
detect containers the test-probes will extend to seal and pressurize the containers. The Pressure Test
ensures the container reaches the specied Peak Pressure. If any one of the containers fails to reach
Peak Pressure, that container will be rejected for a Fill Failure.
7.3 Test 1 (T1) (Stabilize Test)
T1 is considered a pressure stabilization period. T1 is the time allowed for pressure curve to atten
out. (See the graph above) Test 1 will reject the container if Maximum % percent value is exceeded. If
Maximum % value is not exceeded, Test 2 is performed.
7.4 Test 2 (T2) (Leak Test)
Test 2 is performed for as much time as the conveyor speed and container travel will allow. This is done
so the smallest possible leak can be detected. In Test 2 the container will be rejected if the T2 Maximum
% percent value is exceeded. If the T2 Maximum % is not exceeded the container is considered good.
At the end of this period, the probe is retracted and the test cycle is completed.

7.5 Pressure Decay Values
Unless otherwise specied the pressure units of measurement entered or displayed in the HMI are
shown in Inches of Water Column (IWC).
Photo Eye Function and Position
7.5.1 Photo Eyes Introduction and Positions
Containers transition from the production line conveyor into the FlexPitch conveyor for leak testing.
During this transition containers will be monitored and controlled by various photo eyes. The machine
will reject failed or untested containers at the reject station.
Figure 2: Reject Cylinder
Table 5: Photo eye Function Table
Ref # Photo Eye Function
1 Container Present Photo-Eye Monitors the line of incoming containers to determine that a container is present to initi-
ate the test cycle.
2 Downstream Jam Photo-Eye Temporarily pauses the machine when the sensor eld is broken. It automatically restarts
the machine when the sensor eld is clear
3 Reject Photo Eye
Detects a failed container and res the reject cylinder at the appropriate time. It is also
used to detect untested containers that may have been missed by the Container Present
Photo-eye (issues an Unexpected Container Warning)
4Reject Verication/Chute Moni-
tor Photo-Eye
Veries that rejected containers have left production line. If the sensor fails to detect the
container, or if the sensor eld has not been broken after a reject occurs, the machine
and conveyor will shut down and an alarm condition called a Reject Verication Fault is
generated.
