System Components

Fiber Recoaters with Linear Proof Testers Chapter 4: Device Selection
Rev A, September 14, 2020 Page 5
Device Selection
When purchasing a PTR406 or PTR406B, it is necessary to select a mold assembly and fiber holding block inserts
that best match the desired coating diameters of your fiber.
4.1. Automatic and Remote Manual Injection System
The PTR406 and PTR406B are both manual fiber Recoaters with an integrated linear Proof Tester. The major
difference between the two products is the type of injection system utilized by the device. The PTR406 comes with
the automatic recoat injection pump fitted inside the unit. This pump system can be activated either by the “Inject”
button on top of the unit or with the Handset Controller. An automatic injection system will inject a predetermined
volume of recoat material into the mold assembly. It is compatible with high-index recoat material only.
The PTR406B comes with a manual injection system. This pump system provides a method of manually dispensing
recoat material directly from the recoat bottle into the injection port. This system consists of a syringe with a knurled
dispensing screw, which is fitted to a distribution valve with a two-position selection lever. It is compatible with both
high- and low-index recoat material.
4.2. Mold Assemblies
The Mold Assemblies are composed of split quartz mold plates which, when closed, form the cylindrical mold cavity
around the exposed section of the fiber being recoated. When purchasing the Recoater for the first time, it is
necessary to choose a mold assembly that is appropriate for the desired fiber coating diameter. They are available
for Ø280 µm, Ø430 µm, or Ø600 µm fiber coatings. Custom mold sizes up to Ø900 µm are available; please contact
Thorlabs for more information. Additional mold assemblies may also be purchased and swapped out by the user.
The assembly simply screws to the top of the device, making the removal and installation simple and easy.

4.3. Insert Selection
When purchasing a PTR406/PTR406B, the proper set of inserts need to be selected. A total of four inserts (two top
and two bottom) are required for a full unit. The inserts are seated in and secured to the fiber holding blocks. They
can easily be swapped out for different sizes, allowing our Recoaters to adapt quickly should different fiber coating
sizes be desired. The VHJ Series inserts (designed for Recoaters with linear Proof Testers) are compatible with
fiber coating sizes ranging from Ø80 µm to Ø1000 µm.

Setup
5.1. Removing the Shipping Fixture
Loosen the eight set screws in the bases of the fiber holding blocks. Open the lids. Remove the shipping fixture.
Place it in a safe location. You may need it again, should you ever need to ship the unit back for service.
5.2. Attaching the Manual Recoat Injector
If your unit is a PTR406B, you will need to attach the manual recoat injector to the side of the unit. Place the injector
on the side of the unit and attach it to the unit using the two cap screws from the attached bag. Use the 3/32” hex
key to tighten the screws.
Attaching the Manual Recoat Injector
5.3. Installing the Inserts
Put the top inserts in place and capture them using the set screws in the lid. Use the 0.035" hex key to tighten the
set screws. Put the bottom inserts in place and capture them using the set screws in the base of the fiber holding
block, using the same Hex key. As you install the inserts, make sure they are fully seated as you tighten the set
screws.

Installing the Inserts
5.4. Attaching the Recoat Mold Assembly
Make sure that the base plate and bottom of the mold assembly are cleaned of any dirt particles. Insert the pin
assembly by inserting the long end into the recoat mold assembly. Verify that the pin assembly moves up and
down freely.
Placing the Recoat Mold
Plug the ribbon cable connector that emerges from the center slot into the bottom of the LED board on the
underside of the mold. Lower the assembly straight down, making sure the pin assembly enters through the
correct hole, and attach the recoat mold assembly using five of the screws from the attached bag. Lightly tighten
two diagonal screws; leave the rest loose. The screws need to be somewhat loose to allow for adjustment of the
recoat assembly. Open the recoat station top and the tops of the fiber holding blocks. Clamp a length of coated
fiber between the holding blocks so that the fiber is under slight tension. (A fiber nominally smaller than that of the
diameter of the recoat mold should be used.) Using a 10X magnifying loupe, view the fiber straight down at the
right-hand edge of recoat station, as shown below. Adjust the recoat assembly such that the fiber is centered in
the bottom recoat groove. Repeat this procedure while viewing the fiber at the left edge of the recoat station.
Tighten the recoat flange screws and re-check the fiber alignment.

Page 8 TTN176280-D02
Aligning the Recoat Mold
Connect the green recoat material tube to the inject port on the top of the lid.
5.5. Connecting the Cables
1. Plug in the AC power cord. The power supply
accepts an AC input of 100 - 240 VAC; 47 -
63 Hz.
2. Connect the AC power cord to the external
power supply.
3. Connect the DC power cable to the unit.

Fiber Recoaters with Linear Proof Testers Chapter 5: Setup
Rev A, September 14, 2020 Page 9
4. Locate the USB Y-cable that is included with the
unit. Locate the USB type A plug that is by itself
on a long pigtail.
5.
Plug this USB plug into the top USB socket of the
handset. Note that the USB socket on the side of
the handset is dedicated to connecting a USB
flash drive for importing/exporting fiber files and
updating software. Leave it unpopulated for now.
6. Plug the USB Type B plug of the Y-cable into its
socket on the back of the unit. This will provide
data to the handset controller.
7. Plug the remaining USB Type A plug of the Y-
cable into its socket on the back of the unit. This
will provide power to the handset controller.
5.6. Priming the Mold
Before dispensing recoat material, it is necessary to fill the recoat material bottle with recoat material and prime the
recoat mold. Priming the recoat mold will make it easier to dispense the exact right amount of acrylate material
when recoating a fiber, and it will eliminate air bubbles that may be trapped in the recoat material. Refer to Chapter
7 for instructions on performing these steps.

Page 10 TTN176280-D02
Controlling the PTR406/PTR406
This device can be operated using either the three (3)
buttons on the unit or with the Handset Controller.
6.1. Unit Control Buttons
The PTR406/PTR406B has three Unit Control Buttons that enable the user to inject and cure recoat material as
well as test the strength of a fusion splice. The inject button is only enabled on the PTR406, which comes with the
automatic injection system. All parameters are preset and cannot be changed without the Handset Controller in
conjunction with the Unit Control Buttons (see below for control options). The controller is also necessary for readout
of the proof test values, test history logging, and recoat material usage monitoring.
Unit Control Buttons
Inject Button: Inject a preset amount of recoat material into the mold (for the PTR406 only). The Inject Button
can be configured to inject recoat material while it is pressed (Momentary Injection).
Cure Button: If the recoat mold is closed, pressing the Cure Button turns on full power to the UV lamps for
the preset cure time. If the recoat mold is open, holding down the Cure Button will illuminate
the UV lamps at low power (no UV output). This allows for a visual inspection of the lamps.
Test Button: Activates a proof test with the current parameter settings stored within the main unit. The right-
hand fiber holding block will move linearly to the right to apply the set tension to the fiber. The
load will be held for a set “hold time,” after which the fiber holding block will move back left to
the home position.
Handset Controller

Rev A, September 14, 2020 Page 11
6.2. Power Up
With the Handset Controller properly connected to the unit, turn on the PTR406/PTR406B using the switch located
at the back of the unit.
The system will go through an initialization process that takes from 15 to 90 seconds, during which time it will home
and fill the internal recoat pump (if so equipped) and home the linear Proof Tester. During initialization, the handset
Controller will auto-detect the PTR406/PTR406B and display the main screen. From here the User can start
injecting, curing, testing, viewing, or editing Parameters and select items on the toolbar
The Handset Controller provides a simple, easy to use interface for configuring, controlling, and monitoring PTR
and LDC series machines. The following sections contain a quick start guide followed by a more detailed view of
the features and capabilities of the Handset Controller.
6.3. A Quick Start Guide to Using the Handset Controller

6.4. PTR406/PTR406B Parameters
The following sections describe the parameters that control PTR406/PTR406B.

Fiber Recoaters with Linear Proof Testers Chapter 6: Controlling the PTR406/PTR406B
Page 14 TTN176280-D02
6.4.1. Inject Parameters (PTR406 Only)
The Inject parameters are defined as follows:
Inject Quantity: The volume of recoat material in microliters (µl) injected into the mold.
Inject Rate: The speed at which recoat material is injected into the mold in microliters per second
(µl/sec). The maximum inject rate is 1.8 µl/sec. The recommended inject rate for
recoating is 0.2 µl/sec.
Add Quantity: The percentage of Inject Quantity that can be manually injected to the mold after the
Inject sequence is complete. The Handset Controller displays the Add Button in the Inject
Screen once the Inject sequence is complete. The Add feature is especially useful in
situations where there is variability in the position of strip shoulders/length of recoat
required.
Fill Rate: The rate at which recoat material is filled into the auto-inject pump’s reservoir. The
maximum fill rate is 1.8 µl/sec.
Shrink Factor: The Shrink Factor is the amount of material injected into the recoat mold during the early
stages of curing. This is entered as a percentage of the initial Inject volume and is
intended to compensate for material shrinkage during cure. Typical values for Shrink
Factor are 3 to 6%.
Shrink Time: Shrink Time specifies the time period over which any additional material is injected into
the mold during cure. It is expressed as a percentage (%) of Cure Time.
Momentary Injection: This can be enabled or disabled. When enabled, pressing the Inject button on the
PTR406 causes the machine to inject recoat material for as long as the Inject button is
down. When disabled, pressing the Inject button causes the predefined Inject Quantity
to be injected. Note that pressing the Inject button on the Handset Controller will always
deliver the predetermined Inject Quantity.
Purge Cycles: This sets the number of purge cycles the unit will perform when the Purge command is
sent. Purge cycles are necessary to remove air from the injection system. It is
recommended to perform at least 5 purge cycles every time recoat material is replaced.
Purge Rate: The rate at which the pump will purge and fill material during a purge cycle. Maximum
purge rate is 1.8 µl/sec.
6.4.2. Cure Parameters
The Cure parameters are defined as follows:
Cure Time: The duration of the recoat material cure (1 to 480 seconds).
LED Set X Start: Specifies switch-on time of each pair of LEDs. The parameter is a percentage (%) of the
total cure time. The LEDs are numbered in pairs from 1 to 7 starting from the outside.
LED Set X Stop: Specifies the switch-off time of each pair of LEDs. The parameter is a percentage (%) of
the total cure time. The LEDs are numbered in pairs from 1 to 7 starting from the outside.
LED Set X Power: Sets the LED power as a percentage. The LEDs are numbered in pairs from 1 to 7
starting from the outside.

Fiber Recoaters with Linear Proof Testers Chapter 6: Controlling the PTR406/PTR406B
Rev A, September 14, 2020 Page 15
Warning
Do not look directly at the recoat assembly while the recoat LEDs are on. The recoat LEDs emit ultra-
violet radiation which can cause damage to the eyes. The mold must be closed during recoat LED
operation.
6.4.3. Proof Test Parameters
The proof test parameters are defined as follows:
Prooftest Level: The load or tension to which the fiber is to be proof tested in either grams, GPa, kpsi,
lb, or N.
Prooftest Units: The unit of measurement, this can be either grams (g), gigapascals (GPa),
Kilo-pounds per square inch (kpsi), pounds (lb) or Newtons (N).
Prooftest Hold Time: Also referred to as ‘Dwell Time,’ the amount of time in seconds that the Peak Tension
is held for.
Prooftest Ramp: The approximate time in seconds required to reach the Peak Tension.
Fiber Diameter: The diameter of the fiber in microns (µm). This diameter is required to calculate units
of tension (kpsi & GPa). Note: Make sure to enter the diameter of the fiber, not the
diameter of the coating.

Fiber Recoaters with Linear Proof Testers Chapter 7: Handset Controller Reference
Page 16 TTN176280-D02
Handset Controller Reference
The handset controller must be connected to a Vytran LDC/PTR module via the supplied Y-cable to function. Upon
switching on the power to the Vytran LDC/PTR unit, the handset controller will turn on and will require approximately
1 minute of boot up time. At this time, the screen will display the Thorlabs logo, which may flash a few times.
The Handset controller will automatically search for a connected Vytran LDC/PTR module and automatically
configure itself for that module, in this case the PTR406/PTR406B.
It is recommended that the Handset Controller remains connected to a single machine in order to benefit from
machine status monitoring built into the controller. The PTR406/PTR406B can, however, operate without the
Handset Controller attached, and through use of the blue buttons will carry out Inject and Cure using the last set of
parameters that were uploaded to it.
At startup, the Handset Controller will always read parameters from the PTR406/PTR406B, meaning that the
parameters that appear on the screen will always be the parameters that have been uploaded to the unit connected.
The Handset Controller provides a second USB port, labeled Program Port, to which fiber files can be imported and
exported via a flash drive. This port also allows the handset application to be updated via a flash drive.
7.1. PTR406/406B Main Screen
The PTR406/PTR406B Main Screen, much like the Main Screen for any other Vytran PTR or LDC module, shares
a common theme. It has a menu bar, one or more control (action) buttons, and a list of relevant current parameters.
During operation, runtime messages are displayed.
At the top of the screen, the handset shows the type of module detected (in this case PTR406 Manual Recoater –
Linear Proof Tester). The file currently opened (blank if none) is displayed just below the toolbar. The toolbar
provides access to the File menu, Edit menu to change parameters, and the Tools menu.
