LINEAR
METER
SYSTEM
LINEAR METER
ELECTRICAL
ENCLOSURE
The Fluid Kinetics linear metering system is designed to dispense high viscosity materials at a programmable rate. When using multiple component materials, the linear metering system’s unique design insures a consistent dispense ratio between the different materials. The linear meter system is composed of a linear meter, a dispense gun, an electrical control enclosure, and pneumatic solenoids.
The linear meter is a stepper motor driven, two rod, reciprocating design with stationary seals. During the dispense cycle, the air actuated dispense gun is opened and the stepper motor is energized. The stepper motor turns a ball screw mechanism that moves the two dispense rods into their respective metering chambers. The dispense rods displace the material in the metering chambers forcing them out the dispense gun. As the materials leave the dispense gun, they pass through a disposable static mixer blending them together. When the dispense is complete the dispense gun is closed.
During the refill cycle, the air actuated inlet valves are opened and the stepper motor’s direction is reversed. As the dispense rods are withdrawn the material supply system refills the metering chambers. When the dispense rods reach the home position, the stepper motor is turned off and the inlet valves are closed. The linear metering system is ready for the next dispense cycle.
The linear meter is equipped with two pressure transducers that continuously monitor the pressure of each material. Also mounted on the meter are pressure relief valves designed to open if the material pressure exceeds 1500 psi.
The electrical enclosure contains the controls necessary to operate the linear meter. Mounted on the door, are the Power On pushbutton and indicator light and the Power Off pushbutton. Also mounted on the door is the Allen Bradley
PanelView operator interface. The operator interface is displays the current status of the meter and the pressures of both materials. It is also used to access and adjust the meter parameters and clear any faults detected during the operation of the system
Located inside the electrical enclosure is the Master Control Relay that applies electrical power to the system. Also inside the enclosure is an Allen
Bradley Compact Logix programmable logic control, a stepper motor drive system, a +24 VDC power supply, a +5 VDC power supply, and an Ethernet switch.
The PLC interfaces to the PanelView and controls the operation of the linear meter. The CompactLogix system is capable of Ethernet communication to external devices through the Ethernet switch installed in the enclosure.

ELECTRICAL ENCLOSURE -

MY039 - Linear Metering System Instruction Manual
The stepper motor drive system is composed of a Superior Electric S2000-
OF oscillator follower and a Superior Electric S2000-D6 stepper motor drive.
The oscillator follower accepts a 0 to 10 volt DC analog signal from the PLC and converts this to a step signal to control the speed of the stepper motor.
The oscillator follower also accepts a direction signal from the PLC. Both these signals are supplied to the stepper motor drive for control of the stepper motor. An encoder mounted on the stepper motor sends pulses to the high speed counter card in the PLC. These pulses are used by the PLC to calculate the meter dispense rate and dispense quantity.
The pressure transducers are used to continuously monitor the pressure of each of the two materials. The Omega pressure transducer returns a 0-10V signal to the PLC’s Analog Input Module that corresponds to the actual material pressure.
If the pressure fault monitoring is enabled then the material pressures are monitored during the dispense and refill cycles. During the dispense cycle, if the pressure of either material exceeds the maximum set point pressure, the dispense is halted and a system fault is generated. This is to prevent damage to the meter seals by excessive pressure. During the refill cycle, if the pressure of either material falls below the minimum set point pressure, the refill is halted and a system fault is generated. This is to prevent air from being drawn into the meter system from a malfunctioning material supply system.

OPERATION
MANUAL
OPERATION
Section 3 - Operation
In the automatic mode of operation, the linear meter is controlled by an external device. The meter dispenses when it receives a dispense signal from the line controller. It continues to dispense for as long as the dispense signal is present or until it reaches the end of its stroke. The meter does not refill until it receives the refill signal from the line controller.
The quantity of material dispensed on each part is controlled by the meter dispense speed and the duration of the dispense signal. The dispense speed may be changed in the Dispense Menu.
The meter is rated for a maximum dispense pressure of
1500 psi. After increasing the dispense speed, check the material pressure during a dispense cycle to insure it does not exceed this pressure.
The refill speed may also be adjusted in the Dispense Menu screen.
If the refill speed is adjusted too high, the meter can develop material voids causing dispense problems.
There should be a minimum material pressure of 20-30 psi in the meter during the refill process.
If the refill speed is set too low, the meter may generate a Refill Time out system fault. An adjustable timer in the
PLC monitors the time it takes the meter to refill. If the refill takes longer than the set time, a system fault is generated.
A manual dispense may also be initiated from the Dispense Setup screen by pressing the green Manual Dispense button. The meter continues to dispense as long as this key is pressed or until the meter runs out of stroke.
When the Manual Dispense key is released, the meter automatically enters the refill mode.

SCREEN
This screen is accessed from the Data Menu. It is used to calibrate the dispense quantity of the linear meter for the material in use. It is necessary because different materials at different pressures will vary in the amount dispensed per step of the Motor. To calibrate the meter, place a container under the gun nozzle and press the DISPENSE START key. The meter will dispense for 10 revolutions. When the meter stops dispensing, measure the quantity, then enter the quantity dispensed in cubic inches.

ROUTINE
MAINTENANCE
The only routine maintenance required on the linear meter is to periodically refill the fluid isolation chambers on the meter body. The fluid lubricates the meter rods and seals helping to prevent material from sticking to either and prolonging seal life.
ADJUSTING THE
PRESSURE RELIEF
VALVES
Each metering chamber is equipped with a spring style pressure relief valve to help prevent damage to the meter seals if the meter is over pressured. To set the valves to the proper relief pressure, follow the procedure listed below:
1.
Disconnect the air supply to the dispense gun or install a “cured” static mixer to block the flow of material out of the dispense gun.
2.
Loosen the locknut on the pressure relief valves for both materials and slowly back the adjusting screws out until it they are almost all the way out.
3.
In the Dispense Menu, press the Manual Dispense key. While watching the pressure gauge for Material ‘A’ slowly turn the adjusting screw until the Material ‘A’ pressure gauge reads approximately 1500 psi. Tighten the locknut.
4.
Repeat the above process for Material ‘B’.
5.
Reconnect air to the dispense gun or replace the ‘cured’ static mixer. Check operation under normal conditions.
