Introduction
Vytran LLC: PTR-200-PRL Polyimide Recoater Operator’s Manual Version 1.2 1
1 Introduction
The PRL-200 is designed for recoating and proof testing polyimide coated fibers. It operates on a coat,
cure and test recoat method, whereby a layer of polyimide is applied to the fiber through a die, followed
by a filament heater to cure the polyimide and upon completing the recoat a linear proof test. When
configured and operated properly, the PTR-200-PRL is capable of producing a high quality and a uniform
polyimide recoat.

1.2 Powering Up
The PTR-200-PRL Power Supply Unit (PSU) accepts an AC input of 90-260 VAC; 47-63 Hz. Connect
both the AC power cord and the DC power cable to the external Power Supply. Connect the Handset
Controller and the DC power cable to the PTR-200-PRL.
Turn on the power supply and then turn on the PTR-200-PRL using the ON/OFF rocker switch located on
the back of the recoater. The PTR-200-PRL will run an initialization process that includes homing the
recoat die and tensioning motors and operating the recoat die (close/open). During the initialization
process, the Handset Controller will display the status of the system. Once the homing process is
completed, the Handset Controller displays the Main Menu screen and the PTR-200-PRL is ready for
recoating.
1.3 Shutting Down
To shut down the PTR-200-PRL:
1. Turn off the PTR-200-PRL using the on/off rocker switch located on the back of the recoater.
2. Turn off the power supply.

2 Controlling the PTR-200-PRL
The PTR-200-PRL is configured and controlled from Vytran’s PRL-200-CX-PRL Handset Controller,
which also provides feedback and status of the unit. If the operator does not need to change parameter
settings or receive status prompts, the Handset Controller can be removed and the unit operated simply
by pressing the blue RECOAT and TEST buttons.
The Handset Controller allows the user to interface with the unit and modify the settings. The Handset
Controller is based on a three (3) menus:
•Main Menu
•Configuration Menu
•Options Menu
Each menu and its contents are described below.
2.1 Main Menu
The Main Menu displays the unit status. From this menu, press the “CFG” button to enter the
Configuration Menu or press the “OPT” button to enter the Options Menu.
2.2 Configuration Menus
There are three (3) levels to the Configuration Menu. At level one the user can select from five (5)
topics - Inject, Undercoat, Overcoat, Recoat Length, or Proof Test. Within each of these topics are the
parameters which can be viewed and/or copied. Below is a description of the five (5) topics and each
topics parameters.
2.2.1 Inject
Inject Rate (µl/sec): This parameter is the polyimide injection rate, in microliters per
second, into the die. The optimum Inject Rate will be dependant on
the polyimide material being used.
Undercoat Qty. (µl): This parameter is the quantity of polyimide material, in microliters,
injected into the die for the first loop of the head (the undercoat).
The optimum Undercoat Qty will be primarily dependant on the bare
fiber diameter, die size, and the length of the recoat.
Overcoat Qty. (µl): This parameter is the quantity of polyimide material injected into the
die, in microliters, after the first loop of the head. The optimum
Overcoat Qty will be primarily dependant on the die size, and the
length of the recoat.
2.2.2 Undercoat
Head Sweep Vel. (steps/sec): This parameter is the velocity of the head, in steps/sec, for the first
loop of depositing polyimide. The optimum Head Sweep Velocity
will be dependant on the bare fiber diameter, die size, and material
being deposited.
Left Precure Temp
(degrees centigrade): This parameter is the approximate temperature, in degrees
centigrade, applied to the left heater during a polyimide deposition.
The optimum Left Precure Temp will be dependant on the Head
Sweep Velocity, and material being deposited. The temperature is
calibrated at the center of the heater while stationary. The Left
Precure Temp is designed to evaporate the volatiles of the polyimide
being deposited.

temperature is calibrated at the center of the heater while stationary.
The Left Cure Temp is designed to imidize the polyimide after the
volatiles have been evaporated.
Right Precure Temp
(degrees centigrade): This parameter is the approximate temperature, in degrees
centigrade, applied to the right heater during a polyimide deposition.
The optimum Right Precure Temp will be dependant on the Head
Sweep Velocity, and material being deposited. The temperature is
calibrated at the center of the heater while stationary. The Right
Precure Temp is designed to evaporate the volatiles of the polyimide
being deposited.
Right Cure Temp
(degrees centigrade): This parameter is the approximate temperature, in degrees
centigrade, applied to the right heater during imidization (the pass
after deposition). The optimum Right Cure Temp will be dependant
on the Head Sweep Velocity and the polyimide material. The
temperature is calibrated at the center of the heater while stationary.
The Right Cure Temp is designed to imidize the polyimide after the
volatiles have been evaporated.
2.2.3 Overcoat
Number of Overcoats: This parameter is the number of loops the head will make. The
optimum Number of Overcoats will be dependant on the polyimide
thickness layer desired (which will be dependant on the undercoat
layer thickness and the parameter settings for the overcoat(s)).
Head Sweep Vel (steps/sec): This parameter is the velocity of the head, in steps/sec, for the first
loop of depositing polyimide. The optimum Head Sweep Velocity
will be dependant on the die size, and material being deposited.
Left Precure Temp
(degrees centigrade): This parameter is the approximate temperature, in degrees
centigrade, applied to the left heater during a polyimide deposition.
The optimum Left Precure Temp will be dependant on the Head
Sweep Velocity, and material being deposited. The temperature is
calibrated at the center of the heater while stationary. The Left
Precure Temp is designed to evaporate the volatiles of the polyimide
being deposited.
Left Cure Temp
(degrees centigrade): This parameter is the approximate temperature, in degrees
centigrade, applied to the left heater during imidization (the pass
after deposition). The optimum Left Cure Temp will be dependant
on the Head Sweep Velocity and the polyimide material. The
temperature is calibrated at the center of the heater while stationary.
The Left Cure Temp is designed to imidize the polyimide after the
volatiles have been evaporated.
Right Precure Temp
(degrees centigrade): This parameter is the approximate temperature, in degrees
centigrade, applied to the right heater during a polyimide deposition.

Vytran LLC: PTR-200-PRL Polyimide Recoater Operator’s Manual Version 1.2 5
Right Cure Temp
(degrees centigrade): This parameter is the approximate temperature, in degrees
centigrade, applied to the right heater during imidization (the pass
after deposition). The optimum Right Cure Temp will be dependant
on the Head Sweep Velocity and the polyimide material. The
temperature is calibrated at the center of the heater while stationary.
The Right Cure Temp is designed to imidize the polyimide after the
volatiles have been evaporated.
Overlap Delta (mm): This parameter is the additional distance, in millimeters, the head
will travel on each pass. This will effectively taper the transition from
original polyimide to recoated polyimide.
2.2.4 Recoat Length
Recoat Length (mm): This parameter is the desired bare fiber length, in millimeters, to be
recoated. The actual recoat length will be approximately 8
millimeters longer on each end in order to compensate for the width
of the head and the fiber load position.
2.2.5 Proof Test
Proof Test Units: This menu allows the user to select the desired units for displaying
the Proof Test Level. Unit selections are: Newtons, kpsi, and grams.
Proof Test Level (units): This parameter is the Proof Test Level, in units user selected, to be
applied after the recoat has been completed.
Proof Test Rate (mm/sec) This parameter is the rate, in millimeters per second, at which the
Proof Test Level will be applied. The optimum rate is that which
achieves the desired proof test level within 3 - 5 seconds of load
applying time.

2.3 Options Menu
From the Options Menu, various system level configuration parameters and functions can be edited or
executed.
Recoat Tension (Newtons): This parameter is the tension, in Newtons, applied to the fiber prior
to initiating a recoat. The PTR-200-PRL also monitors the tension
during the recoat and will automatically abort if the tension varies
significantly from the Recoat Tension. The auto abort is intended to
protect both the die and fiber.
Heater Settle Time (msec): This parameter is the amount of time, in milliseconds, allowed for the
heater to stabilize when changing temperatures.
Die Close Time (msec): This parameter is the amount of time, in milliseconds, allowed for the
die to close prior to execution of the subsequent process.
Fiber Unload Time (msec): This parameter is the amount of time, in milliseconds, allowed for the
operator to unload the fiber prior to the PTR-200-PRL performing a
system reset.
Inject to Die Qty (µL) This option is the quantity of polyimide material, in microliters, which
will be injected into the die upon entering the quantity. This option is
intended for use when changing materials or purging the system
prior to storage.
Head to Home: This option performs a homing of the head and is useful as a
diagnostic tool.
Tension Home: This option performs a homing of the proof test load cell and is
useful as a diagnostic tool.
Move Head to Start: This option performs a movement of the head to the start position.
The start position is calculated based upon the recoat length,
overlap delta, and the number of overcoats. Use of the Head to
Start and Head to Stop options enables the user to verify the correct
recoat length has been entered.
Move Head to Stop: This option performs a movement of the head to the stop position.
The stop position is calculated based upon the recoat length,
overlap delta, and the number of overcoats. Use of the Head to
Start and Head to Stop options enables the user to verify the correct
recoat length has been entered.
Recoat Request State: This option enables or disables the request to input a recoat length
each time the process is run. This option is primarily used when the
length to be recoated varies significantly from recoat to recoat.
Set/Run Purge Cycles: This option is the number of recoat pump purge cycles that will be
run upon entering the quantity.
Recoat Tension This option is the amount of tension that will be applied to the fiber
prior to the recoating.

Recoat Injection System
Vytran LLC: PTR-200-PRL Polyimide Recoater Operator’s Manual Version 1.2 15
3 Recoat Injection System
The PTR-200-PRL has an automatic recoat injection pump fitted inside the unit. The pump is based on
an automated syringe and distribution valve that can select one of three ports (Fill, Purge, or Inject)
through which it can either draw or inject recoat material (see Figure 3). A bottle containing recoat
material is installed directly on the pump, with the pump “Fill” tube inserted into the bottom of the bottle. A
“Purge” tube runs from the pump to the top of the recoat bottle, and is used for cycling material back into
the bottle. An “Inject” tube runs from the pump to the inject port of the die, which is located in the center
of the lower right die. Once all air is purged from the injection system, the pump provides very accurate
control of the volume and velocity of recoat material injection.
The recommended recoat material for use in the PTR-200-PRL is Pyralin PI2525, which is manufactured
by HD MicroSystems. This is a fast imidizing at lower temperature coating. Do not attempt to use
alternate recoat materials without first consulting Vytran on compatibility with the PRL.
Note: Pyralin PI2525 recoat material does have a limited shelf life of approximately 24 months from date
of manufacture when stored at 0 to 18 degrees Centigrade. PI2525 is stable at room temperature (21
degrees Centigrade) for approximately 4 weeks with no significant change in properties. Using material
that has passed its expiration date may cause both pump performance and recoat quality issues.
3.1 Priming the Injection System
It is very important to remove all air from the recoat injection system prior to performing a recoat. When
operating the system for the first time, the pump must be filled with recoat material and cleared of all air in
the pump and tubing. In order to clear the inject tube, recoat material must be injected out through the
mold inject port and collected and disposed of. Make sure to have cotton swabs and NMP (1-Methyl-2-
pyrrolidinone) available for this purpose prior to starting this procedure. NMP is the recommended
solvent for cleaning uncured polyimide recoat material.
WARNING: Polyimide recoat materials can be hazardous to your health if not handled properly. Read
the Material Safety Data Sheet provided in Appendix X, and make sure to follow all precautionary
guidelines when working with this material.
To prime the recoat injection system:
1. Turn off power to the PTR-200-PRL.
2. Remove the front plate of the PTR-200-PRL by using the 3/32 Allen wrench provided in the tool
kit to remove the four (4) black socket-head cap screws located at the corners of the plate.
3. The recoat pump is located on the left side of the PTR-200-PRL as shown in Figure 2. Unscrew
the brown recoat bottle located at the front of the pump and remove by angling out through the
front opening. The red Fill tube will flex to allow removal.
4. For new systems, replace the empty recoat bottle shipped with the unit with a new bottle of recoat
material. For systems that have previously been run with recoat material, the recoat injection
system should be flushed clean prior to adding new material (see 5.5).
5. Screw the new recoat bottle into place and replace the front panel and the four (4) socket head
cap screws.
