If you are designing your own motor mount, refer to Figure 1,
"Motor Dimensions and Mounting Hole Pattern" to understand
the mechanical requirements for attaching the motor to your
mounting system. Primary considerations you should keep in
mind when designing your system include:
•
Programmable Turntable Controller
•
•
•
Do not have the motor actually hanging or otherwise
supported by your turntable shaft. The motor can be
supported by the turntable pit, if sufficiently strong. The
motor is heavy and should not be allowed to stress the
turntable bridge or shaft mechanism.
Be sure the mount is rigid. Since the controller can achieve
very small step increments, the motor should not be allowed
to move rotationally or laterally.
Be sure the mount keeps the motor perpendicular to the
turntable shaft. Your mount should make sure that the motor
and turntable shafts stay in alignment, and do not connect to
each other "off angle".
Design the mount so that it shares a common mounting
surface with the turntable, such as the layout surface or
supporting benchwork immediately connected to the
turntable. Do not use benchwork that otherwise supports the
layout. The objective is to minimize mis-alignment effects
related to possible expansion and contraction of the layout or
supporting benchwork.
INTRODUCTION
Before you begin installation and programming of your new
turntable controller, be sure to read through these instructions
completely. Also, review the PTC Model III Product Overview as
well as the Basic Motor Mount Installation Instructions, if you
are using the optional Motor Mount Kit.
The PTC is not difficult to install, but as with any precision
mechanism, some time and care will be needed to achieve a neat,
reliable installation.
The main steps involved in installing your PTC Model III are:
•
•
•
•
•
Motor Installation,
Controller Installation,
Track Selector Installation,
System Check-Out, and
Programming.
MOTOR INSTALLATION
If these guidelines are followed, your installation should provide
years of reliable service.
CONTROLLER INSTALLATION
Controller installation is simple, and only requires a suitable
location under the benchwork to rest the controller. Typically, a
small shelf is attached to the benchwork if no other location is
available. When selecting a mounting location, be sure that:
•
•
•
There are two main options for motor installation:
•
•
Use the optional Motor Mount Kit, or
Design your own motor mount system.
In general, use of the motor mount kit is recommended unless
you have a special situation where the kit is not suitable, or if you
are designing a new or scratchbuilt turntable where you can
integrate the motor support system into the turntable design. If
using the Motor Mount Kit, refer to the detailed instructions
included with the kit and install it before proceeding here.
The mounting location is within 24” of the turntable, which
is the length of the motor cable. The short cable length is
recommended to minimize the potential for the motor to pick
up unwanted electrical noise. However, optional 3', 6', and
10' extension cables are available, if needed.
Be sure the mounting location is within 3' of where you plan
to mount the Track Selector panel controls, which is the
length of that cable. Again, shorter cables are better, but 6
and 10 foot cables are available if needed.
Lastly, be sure the front panel of the controller is visible for
programming later. You will need to see the front panel on
occasion (not during normal operation, usually), so be sure
you can see it without too much trouble.
Once you have selected your mounting location:
1. Mount the controller.
2.
Connect the Motor to the Controller. Note that the motor
cable connector has two small tabs on one side; these tabs
should be facing up when you insert it into the Controller.

Figure 3: Track Selector Mounting Hole Pattern
If you have ordered the optional Track Power Reversing
capability, connect the bridge track power leads to terminals "A"
and "B" on the rear of the Controller. Polarity is not important.
Connect the bridge track power feeders to terminals "C" and "D"
on the controller:
TRACK SELECTOR INSTALLATION
Orientation of the Selector Module is not important. For example,
you can mount the module upside down, "left" or "right" facing.
Refer to Figure 3, "Track Selector Mounting Hole Pattern", to
familiarize yourself with the layout of the hole patterns and the
drills required. After you have determined the hole locations:
1.
Drill the required hole pattern.
2.
If you have not already done so, install the track selector
pushbuttons you are using in your control panel. If you are
using your own switches, be sure the leads are sufficiently
long (about 16" minimum is recommended, for ease in
working later). Also, it is recommended that you use two
different wire colors, one color for each terminal, as well as
"tin" (apply solder to) the wire ends of the switch leads.
Tinning the leads will improve long term reliability of the
connections to the Track Selector.
3.
Refer to Figure 5, “Track Selector Mounting Assembly with
Stacked Expansion Module, Exploded View”:
Figure 2: Controller (Rear View) and Bridge Connections
Note: Do not connect track power through the Controller if you
do not have the Track Reversing Feature installed. Power will not
be fed through.
After you have double checked the connections so far, continue
to installation of the Track Selector Modules.

5.
Carefully remove the Fiberglass Cover Plate installed on the
Primary Pushbutton Track Selector. To remove, carefully
squeeze the retainer tabs on the standoff and push them
through.
10. Once wired, carefully install the free end of Expansion
Module's input cable ("Daisy Chain Cable") onto the
Primary Pushbutton Selector. Refer to Figure 6, "Pushbutton
Track Selector Daisy Chain Wiring".
Using the two screws and washers from the hardware kit
supplied, install the Hex Standoff and Nylon Washer
combination onto the the Primary Pushbutton Track Selector
Module.
11. After connecting the Daisy Chain Cable, snap the Expansion
Module to the Primary Track Selector Module.
6.
If using a Track Selection Expansion Module, leave the
Fiberglass Cover Plate off for now. If not, reinstall the Cover
Plate.
7.
Connect the flat ribbon Track Selector Cable to the Selector
Module. The cable should be connected to the J1 connector,
noted as "Primary" on the Track Selector Module PCB. The
marked edge of the cable must be oriented to line up with the
Pin 1 location of J1. Pin 1 is near the Head/Tail switch
(noted as "SW2" on the PCB).
8.
Referring to Figure 7, “Switch Connections to Track
Selector”, connect the track selection switches to the track
selector module:
8.1. Tie one terminal of each switch together, creating a
common connection to each switch. As shown in Figure
7, connect the common wire to any one of the terminals
of the Ground Connection Block. For example, if using
switches provided with your PTC, connect all of the
green wires together.
◆ Tip: Four ground terminals are provided. If convenient,
you can connect the green wires togther in groups of three.
8.2. Starting with any switch you prefer, install the other
wire of each track selection switch into any one of the
Track Select Input Blocks, number 1 thru 12. If using
switches provided with your PTC, this would be the
white wire.
◆ Note: If you have purchased your PTC with the standard
12 Track Selection capability, you will only 12 terminals
available. If you have ordered your system upgraded to 24
Track Selection capability, you will have 12 additional
terminals available.
Important! Proceed carefully as the modules are wired and
stacked, and take your time. It is likely that the wires may
resemble a bird's nest by the time you are done, and you don't
want to pull out any wires while you are working!
12. Mount the Track Selector Module (or, Track Selector Stack)
through the control panel:
12.1. Remove the red pushbutton cap, LED bezel, and all
switch hardware (nuts and washers) except one nut on
the toggle switch.
12.2. Install the LED bezel through the front of the control
panel.
12.3. Install the Track Selector through the control panel.
The pushbutton switch should rest flush against the
back of the control panel. The LED should protrude
slightly through the LED bezel. Adjust the nut on the
toggle switch so the Track Selector is level with respect
to the rear of the control panel.
12.4. Install the two remaining screws and washers throught
the front panel into the hex standoffs
12.5. Install the lock washer and nut on the toggle switch.
Install the knurled nut on the pushbutton switch;
discard extra nut and lock washer if not needed. Note:
Tighten all screws and switch nuts carefully, do not
overtighten.
12.6. Install the pushbutton cap.
13. Connect the Track Selector Cable to the Controller:
Important! Be sure the marked edge of the cable is on the
8.3. Tighten the set screws to secure the wires into the
terminal block. Note: the terminal blocks are shipped
with the terminals in the "open" position, it is not
necessary to unscrew the set screws further.
8.4. Proceed with the rest of the switches you have installed.
9.
If you are not using a Track Selection Expansion Module,
skip this step and proceed to the next step.
9.1. Refering to Figure 5, note the nylon standoffs used to
support the Expansion Module.
9.2. Relocate the standoffs if necessary, but do not stack the
boards at this time.
RIGHT as you view the rear of the controller. Installing the
Selector Cable in backwards may damage the Selector
Module. Be sure it is correctly installed before turning the
system power on.
9.3. As done in Step 8, wire the additional pushbutton
switches to the Track Selection Expansion Module.
PTC Model III, Pushbutton Selector Installation Instructions and User Manual, Rev 7/10 - Page 8
After you have installed the Track Selector Module(s), double
check your connections. Be sure the main power switch is on the
down (off) position:
PROGRAMMING
15. Plug the Power Supply into the wall outlet. You are now
ready to test and program the Controller.
Programming the PTC involves the following simple steps to
teach the PTC where your lead and service track locations are.
Programming should take about 5 minutes; take your time. Feel
comfortable while programming; you can't hurt anything. If you
are in doubt about making a mistake at any point, don't worry
about it... you can simply restart the programming process.
SYSTEM CHECK-OUT
1.
Testing the installation involves turning on the Controller in
"Index Mode". While in Index Mode, the Controller will
continually turn the motor (and the bridge) clockwise until you
tell it to stop.
1a. Confirm that no pushbuttons are currently pressed (nothing is
resting on the control panel). Identify the lead track, or your
main lead track, that will be the reference track that the
controller will remember as the starting location.
1b. Locate the switch block on the bottom of the Controller. Set
switch #8, the Run/Learn switch, to the "OFF" ("LEARN")
position. Momentum DIP switches must be “OFF”!
1c. Turn on the Controller power (front panel switch to "ON").
1d. The Status Indicator on the control panel will be red very
briefly, then will change to a solid yellow. This indicates that
the controller has powered-up in the "LEARN" mode. Note:
If you had previously programmed the PTC during another
session, all previously programmed settings will be erased at
this point.
14. Plug the Power Supply cable into the Controller, then
1.
Locate the switch block on the bottom of the controller.
Confirm that Switch #8, the Run/Learn switch, is set to Run
("ON").
2.
With the Controller Power Switch in the down (OFF)
position, press and hold the Run/Stop switch on the Control
Panel. You may need a helper for this, if it is not possible
for you to reach the Controller and Control panel at the same
time.
3.
While holding down the Run/Stop button, turn the Power
switch to ON (the UP position).
4.
Let go of the Run/Stop switch.
The power-on LED on the Controller should be lit, the bridge
should begin turning clockwise, and the Status Indicator (LED)
on the control panel should be alternately flashing red and
yellow. If this does not happen, turn off the power and re-check
your connections.
While the bridge is turning, carefully observe the bridge's
movement throughout its full circular rotation. No binding or
"stuttering" should be evident. If there is, turn off the power and
examine the motor installation for any misalignment. Correct any
problems and re-start the Controller in Index Mode to verify the
fix.
◆ Tip: While the bridge is turning in Index Mode, you can make
the bridge stop turning and go into "Single Step Mode" by
pushing the Run/Stop button again. Each new push of the
Run/Stop button will result in the bridge advancing one step. The
Status Indicator will also alternate between solid red and solid
yellow to confirm each individual step. Use this feature to singlestep the turntable through any problem areas of rotation you want
to examine closely. To resume continuous rotation, repeat Steps
1 through 3.
◆ Tip: You can change the speed that the bridge turns during
Indexing, Programming, or normal operation by changing the
PTC speed settings (Switches #1 and #2 on the switch block).
After you have completed the system check out, proceed to
programming!
2.
Initialize the controller. With the power off:
Program the location of the lead track.
Determine which end of the turntable bridge you would like
to be the "head end", or reference point, for programming.
Set the Head/Tail switch to the position you would like it to
be to indicate "Head" (usually up or to the left, depending on
how you installed it in your layout control panel). The
controller will learn your preference. Following the
procedure below, rotate the head end of the bridge to the
location of the lead track:
2a. Press and release the Start/Stop button on the control panel.
The bridge will now begin turning slowly, in a clockwise
direction. The status LED will flash yellow. At this point, it
does not matter where the bridge is pointing or what track it
is lined up with. The bridge will keep turning until you press
the Start/Stop button again.
2b. When the bridge gets within a few degrees of the lead track,
press the Start/Stop button again. The bridge will stop
rotating. The status indicator will be red or green, depending
on where you happened to stop.
2c. Tap the Start/Stop again; the bridge will take a single step
and stop. Keep tapping the Start/Stop button until the bridge
lines up with the lead track. The status indicator will
alternate between red and green to confirm each step.
2d. If you pressed the Start/Stop too many times (you overshoot
the location you want), press and hold the Start/Stop for at
least 3 seconds, then release. The bridge will reverse and
back up about 2°. Tap the Start/Stop to single step the
bridge, lining it up with the lead.
2e. When you have lined up the bridge to the lead track, press
and hold the track selection pushbutton corresponding to the
lead track. The status indicator will flash green to indicate it
PTC Model III, Pushbutton Selector Installation Instructions and User Manual, Rev 7/10 - Page 9
has acknowledged the track selection. Note: If you initially
select the wrong track, release the incorrect button and press
and hold the correct one during the period the LED is
flashing green.
2f. After about 5 seconds, the Status Indicator will flash red.
Release the track selection pushbutton. The controller has
confirmed the selection and is in the process of programming
it into memory.
3.
Program the location of the next track. After the Status
Indicator stops flashing red, it will go back to a solid yellow.
This is to tell you that it is ready to learn the location of the
next track, rotating clockwise. To do this, repeat the same
basic steps:
3a. Press and release the Start/Stop button on the control panel,
to start the bridge turning slowly again.
3b. When the bridge gets within a few degrees of the next track,
press the Start/Stop button to stop the bridge.
3c. Tap Start/Stop button until the bridge lines up with the next
track.
3d. Press and hold the Start/Stop button for 3 seconds to back up
the bridge, if you overshoot the spot you want.
3e. When you have lined up the bridge to the next track, press
and hold the corresponding pushbutton switch.
3f. The Status Indicator will again flash green, then red. Once
red, release the track select pushbutton. The flashing red
signal is your indication that the controller has confirmed
the next track's location and is programming it into memory.
4.
5.
Program the rest of the track locations.
Repeat Step 3 to program the rest of the tracks you have
installed.
Program the tail end positions.
Although most bridges are identical at both ends, many are
not-- the tracks do not line up exactly through the center of
the turntable, and are sometimes offset. In addition, most
turntables have concentricity errors that must be
compensated for.
This is achieved by repeating
programming steps 2 through 4 while teaching the PTC
where the correct locations are for postioning the tail end of
the bridge. In this way, the PTC treats the head and tail end
of the bridge locations "separately" and their respective
concentricity and offset errors are accounted for
automatically. Begin by teaching the controller the correct
position for the aligning the tail end of the bridge with the
lead track programmed in Step 1:
5a. Flip the Head/Tail switch to the "tail" position. The Status
Indicator will not change.
5a. Press and release the Start/Stop button on the control panel,
to start the bridge turning slowly again.
5b. When the tail end of the bridge gets within a few degrees of
the reference (lead) track, press the Start/Stop button to stop
the bridge.
5c. Tap Start/Stop button until the bridge lines up with the lead
track.
5d. Press and hold the Start/Stop button for 3 seconds to back up
the bridge, if you overshoot the lead track.
5e. When you have lined up the bridge to the next track, press
and hold the corresponding pushbutton switch.
5f. The Status Indicator will again flash green, then red. Once
red, release the track select pushbutton. The flashing red
signal is your indication that the controller has confirmed
the next track's location and is programming it into memory.
Repeat these steps to program the rest of the tail end bridge
locations.
6.
Prepare the controller for normal operation.
After the bridge tail locations have been programmed,
configure the controller for normal use:
6a. Turn off the power.
6b. Set Configuration Switch #8, the Run/Learn switch, to
"RUN".
6c. Re-index the bridge to bring the head end of the bridge back
to the lead track location: As in Step 1, hold down the
Run/Stop switch while turning on the power. Release the
Run/Stop switch, and the bridge should begin turning. When
the head end of the bridge approches the lead track, single
step it into proper position.
Important! Be sure the Run/Learn switch is set to "Run"
prior to turning on the power! When the controller is
powered-up in the "Learn" mode, the controller erases any
previously programmed locations in preparation for new
locations.
6d. When the bridge is re-indexed, turn off the power.
Your controller is now fully programmed and ready to go! Refer
to "Operating the PTC" for instructions on using your newly
programmed turntable controller.
Programming hints. Follow these simple guidelines to assure
proper programming of the PTC controller:
•
•
•
•
•
Program all locations you are using in one programming
session.
If you think you have made a mistake during programming
or want to start over, just turn the power off and then on
again to reset the controller. This will erase any settings you
have made while in "LEARN" mode. Important: When
turning off the power, wait at least 5 full seconds before
turning it back on.
Since most bridges are identical at both ends, be sure you
can identify which end of the bridge is the head end so you
can re-index the table later on, if necessary. Use the Index
Mode described in the "System Check Out Section" to reorient the head end of the bridge to the lead track. ◆Tip:
Mark your bridge's head end with a water barrel or other
object to make the head end easy to identify from a distance.
If you add more tracks to your turntable later on, reprogram
the PTC from Step 1.
Avoid removing the motor and/or bracket after you program
the unit, unless you really need to. Although not a problem, it
is an inconvenience because you will not likely be able re-
PTC Model III, Pushbutton Selector Installation Instructions and User Manual, Rev 7/10 - Page 10
align the motor exactly where you had it before. You will
have to reindex the unit after renstallation of the motor.
•
OPERATING THE PTC
After programming, the PTC is ready for use. Operation is
simple:
•
Power-up the controller in "RUN" mode. To do this, be sure
the power switch is OFF. Confirm that Configuration Switch
#8 (the Run/Learn switch) is set to "RUN". Turn on the
power. The controller will also go through its power-on self
test sequence:
• The Status Indicator on the control panel should glow
red briefly, then convert to a steady green to indicate
that the controller has powered-up in the normal "RUN"
mode.
• The controller will do a "power-on self test" function to
confirm proper operation. This wags the bridge
clockwise about 10°, then counterclockwise, then back
again.
•
❑
❑
❑
❑
❑
Set the Head/Tail switch to indicate which end of the bridge
you want lined up at the desired track.
Press the track selection pushbutton corresponding to the
desired track. The Status Indicator will flash yellow to
indicate that it has acknowledged the selection. Note: if you
accidentally press the wrong button, or unintentionally press
a track select button, do nothing. After a short while, the
Status Indicator will revert to solid green. This means the
controlled has ignored the button push and has reset to
standby mode.
While the Status Indicator is flashing yellow, press the
Start/Stop switch. The Status Indicator will flash green. If
momentum is turned on (see later section), the bridge will
start to ramp up speed. Depending on the track selected and
the present position of the bridge's head end, the controller
will automatically rotate the bridge clockwise or counterclockwise the shortest distance needed to line up the desired
end of the bridge up with the selected track location. As the
bridge approaches the desired track, it will start to slow
down (if momentum is enabled), then stop.
To stop the bridge in an emergency. If it is necessary to
"panic stop" the bridge during rotation, simply hit the
Start/Stop button again. The bridge will stop immediately,
with no momentum. The controller will place itself in a
"PAUSE" mode and the Status Indicator will glow red. The
PTC will stay in pause until the Start/Stop button is pressed
again, at which time the PTC will continue its progress.
Operating hints:
•
The PTC will not operate prior to programming. If turned
on, it will not perform any functions and the control panel
Status Indicator will flash yellow to indicate programming is
required.
•
•
When the new track destination you have selected is counterclockwise from the bridge's current location, the controller
will overshoot the target track approximately 2°, then slowly
backtrack clockwise to the desired track. This is normal:
although the PTC gearhead utilizes very high quality gears,
this move is necessary to compensate for the very small
amount of backlash that exists in the gear train.
Important: After turning off the power, let the Controller sit
for a full 5 seconds before turning it back ON. This will
assure that the Controller starts up in the proper reset mode.
Do not turn off the controller power when it is in "Pause"
mode between track locations. Although it is not a problem,
it is an inconvenience since you will have to re-index
(reference) the controller to a known starting point. If reindexing is necessary, the Status Indicator will flash a
"double red" after power-up in "RUN" mode (instead of
green) to indicate that the controller does not "remember"
where the bridge is and needs to be re-indexed.
The stepper motor will get quite warm to the touch. This is
normal, since the motor draws nearly 1 amp of current, even
while stationary.
If momentum is enabled, the maximum momentum
achievable is limited by the maximum speed selected. In
other words, at maximum speed, maximum momentum is
possible.
The controller automatically reduces the
momentum to suit the maximum speed, if the momentum
selected is higher than allowable.
Changing the Momentum and Maximum Speed Settings.
The controller comes preset with speed set at "medium" (switch
#1 on, #2 off) and no momentum (switches #3 and #4 set to off).
The range of speed for the PTC is about 0.2 RPM on "X-Slow"
to about 0.5 RPM on "Fast".
To change these settings, locate configuration switches #1
through #4 on the bottom of the controller. Modify the position
of the individual switches to get the desired momentum and
maximum speed:

Notes on setting speed and momentum:
•
•
•
Momentum is not available if you set the Speed to the XSLOW setting. In this case, the Momentum settings will
have no effect.
The Speed settings effect both the indexing speed and the
controller's normal operating speed. ◆Tip: You may it
helpful to use a slower speed for programming, and a
different speed for normal operation.
The changes you make in these settings will take effect the
next time the controller starts a bridge move. It is not
necessary to turn the power off for your new settings to take
effect.
The PTC Model III Controller has been enhanced to provide the
user with more feedback, so corrective action can be taken if the
controller detects that something is wrong.
All feedback is provided by the Status Indicator by use of
different combinations of colors and flash patterns. Note that the
meaning of the different indications depend on if you currently
have the controller in RUN or LEARN modes. Refer to the table
below for a brief description of the different indications and their
meanings:

Using the Automatic Track Power Reversing Feature.
The Automatic Track Power Reversing ("ATR") feature is an
optional capability whose purpose is to eliminate the need to use
a split ring rail, split commutator, or DPDT switch to reverse the
track power during bridge rotation and operation.
The PTC with Pushbutton Selector supports standard track power
reversing, sometimes called “split ring” emulation, by
remembering where your reference track is (Track #1), and then
automatically reversing the bridge track power whenever the head
end of the bridge moves more than 90 degrees either direction
from that point. This simulates what would happen if you used a
split ring rail to carry power to the bridge, with the split made 90
degrees each direction from the lead track. Refer to the figure
below:

New track selection detected: For Rotary
Track Selectors, this means you have turned
the selector to the new location you wish to
program. For Pushbutton Track Selectors,
this means you have pushed the button
indicating the new location you wish to
program. Note: For Pushbutton Selectors,
continue pressing the pushbutton until the
Controller indicator flashes red (see below).
R-R- ,...
The controller has confirmed the new track
selected and is programming it into memory.
Note: When you first program the controller, the power reversing
relay is initialized to feed power “straight through”, meaning, not
reversed. From that point, the controller remembers each move
and toggles the power as needed.
◆Tip: If you have the automatic Track Power Reversing Feature
and want to turn it off for any reason, turn configuration switch
#5, "TP Enable" to the OFF (disable) position. In this setting, the
Controller will still provide power to the bridge rails, but it will
not reverse it.
◆Tip: If you change the ATR mode, it will not take affect (the
relay will not change state, if needed) until the next bridge move.

Index mode: normal bridge index movement
in progress. Note: When "single stepping" at
the end of the indexing movement, the

acknowleged that one of the track select
pushbuttons has been pressed. Push the
Run/Stop button to confirm selection;
controller will proceed with bridge move.
Wait until ( Y ) goes back to ( G ) to cancel
track selection.
Power-on self test: The controller is set to
"RUN", but it is not programmed. Turn off
controller, set Run/Learn switch to learn.
Turn on power and program track locations.
Controller in PAUSE mode during bridge
move. Push Run/Stop button to resume

Power-on self test: Controller needs to be
reindexed. Hold down Run/Stop button while
turning on power to go to INDEX mode
(Refer to Step 6c under “Preparing the PTC
for Operation”, above).
Power-on self test: The rotary Track Selector
switch is in the wrong position (changed while
power was off). Note current bridge position
and turn rotary switch to proper location.
Controller will recognize correction at end of
flash cycle.
Power-on self test: The Head/Tail switch is
in the wrong position (changed while power
was off). Flip switch to other position.
Controller will recognize correction at end of
flash cycle.
Power-on self test: The Controller has
detected that a button is being pushed during
power on (if using the pushbutton track
selector). Verify that nothing is resting on the
control panel to push the buttons. If nothing
is resting on the buttons, then the Controller is
indicating that a short circuit exists in the
pushbutton wiring. Check the pushbutton
wiring for any shorts.
