Configuration Steps
Menu Item Default Parameters and Functions
English/Metric English Choose English or Metric units.
Encoder Scale 1:1 Choose 1:1 or 1:2 encoder scale. Determines unit of movement per encoder
pulse. If set to 1:2, encoder signal is split so that one unit of movement is
equal to two encoder pulses, allowing finer resolution and more precise
triggering.
Clocking
Method Encoder Choose Encoder or Timer. Timer is an internal clock. If you choose Timer, the conveyor interlock is automatically enabled and cannot be disabled. The
conveyor interlock circuit must be connected when the timer is used.
User Conveyor
Speed 0.0 ft/min or m/min Enter speed of conveyor, in feet or meters per minute. Used for Timer operation only, do not set if encoder is used.
Encoder Alarm Time 5.0 The Encoder Alarm can function in either of two ways, depending on how the
External Interlock menu item is set:
External Interlock Enabled: The encoder alarm is a delay (in seconds)
between the time the encoder stops pulsing and when an alarm message
appears on the display. Do not set this value to zero; doing so will cause the
trigger controller to malfunction. To disable the alarm set this value to a large
number.
External Interlock Disabled: The encoder alarm function is an encoder
pulsing stopped monitor. Refer to Encoder Pulsing Stopped Monitor for
setup instructions.
Sensor Alarm Time 90.0 Enter number of seconds after last sensor signal is received before alarm
message appears. Indicates sensor fault or photoeye-to-reflector
misalignment. Continued...

Menu Item Default Parameters and Functions
Sensor 1-4
Filters 0.0 dly/ext Enter positive number to extend sensor signal, negative number to delay signal. Extend signal to eliminate signal chatter when coating wire goods,
delay signal to skip hangers.
Outputs 4 Choose 4, 6, or 8 trigger outputs. Use 4 or 8 for Sure Coat Modular Gun
Control System, 6 for Sure Coat Mini Stack System, and 4, 6, or 8 for
Versa-Spray systems.
Trigger 1-8
<->
Sensor 1-4
-See Figure 1. Connect trigger outputs to sensors. Any combination can be
set. In the example shown, each output triggers two spray guns. Outputs 1
and 2 spray one side of part, and outputs 3 and 4 spray other side. Part 1
triggers all four outputs, but part 2 only triggers outputs 1 and 3.
NOTE: On the run menu, outputs 1-4 are shown as A-D in normal type, and
outputs 5-8 are shown as A-D in reverse type.
Conveyor Run
Delay 0.0 Enter number of seconds it takes for parts ahead of sensors to start moving after conveyor is started.
Conveyor Stop
Delay 0.0 Enter number of seconds it takes for parts in booth to stop moving after conveyor is stopped.
External
Interlock Disable Choose Disable or Enable. Can be disabled if encoder is used. If clocking method is set to Timer, then external interlock is automatically enabled and
cannot be disabled.
Pickoff
Setpoints Show Choose Show or Hide. When hidden, only Lead and Lag Setpoints are displayed in Setpoint Adjustment menus.

Encoder Pulsing Stopped Monitor
If your system does not have an external conveyor
interlock, the triggering controller must monitor
encoder pulses to indicate when the conveyor has
stopped.
NOTE: This function only works if during the
Configuration procedure you set the external interlock
to Disabled.
To configure the monitor, set the encoder alarm value
to a value that is slightly greater than the elapsed
time between encoder pulses:
NOTE: If the conveyor speed changes as part of the
daily operation, perform this procedure at the
conveyor’s slowest operating speed.
1. Set the Conveyor Run and Conveyor Stop delays
to 0.0.
2. Start the conveyor. The encoder should be
pulsing.
3. Press the Manual key to turn on the spray guns.
4. Decrease the Encoder Alarm delay value until the
spray guns start to turn on and off repeatedly.
NOTE: If the Encoder Alarm delay value is less
than the time elapsed between encoder pulses,
the spray guns will turn on and off repeatedly.
5. Increase the Encoder Alarm delay value (0.1
second at a time) until the spray guns spray
continuously.
6. Add 0.2-0.4 to the Encoder Alarm delay value to
make sure that the spray guns will not turn off if
the conveyor speed varies slightly.
NOTE: The spray guns will turn off if the time
between encoder pulses exceeds the Encoder Alarm
delay value. The next time that an encoder pulse is
received, the spray guns will turn on again.

Calibrating the Triggering Controller
1. Choose a test part. It can be a production part or
a piece of cardboard. It will not be coated.
2. Measure the part length as it is hung on the
conveyor. The measurement must be in real
world units, so if you are scaling to inches
measure in inches.
3. Enter Configure controller mode.
4. Make sure Encoder scale is set correctly.
5. Go to the RESET Enc Counts menu.
6. Press the OK key to enter edit mode.
7. Press the Select+ or Select- key to reset the
counts to zero.
8. Press the OK key to exit edit mode.
9. Hang the test part on the conveyor, ahead of the
photoeyes.
10. Start the conveyor.
As the part moves through the photoeyes the
controller measures it in counts. When the part
passes by the photoeyes the scaling adjustment is
set in the controller. This scale is displayed on the
RESET Enc Counts menu.
11. Go to the Encoder CAL menu.
12. Press the OK key to enter edit mode.
13. Use the Select+ and Select- keys to enter the
length of the part you measured in step 2. The
more accurate the measurement is, the more
accurate the triggering will be.
14. Press the OK key to exit edit mode. The
triggering controller is now scaled to real world
units of inches or centimeters.
Setting Trigger Points
Triggering setup consists of determining and setting
three values for each output: pickoff, lead, and lag.
All values are entered in real-world units of inches or
centimeters.
Finding Starting Pickoff Points
See Figure 2. The pickoff point is the distance from
the sensors to the spray guns, measured in
real-world units (inches or centimeters). Use this
procedure to obtain a starting value for each bank of
guns (outputs), then adjust it as necessary to obtain
the desired accuracy.
NOTE: Once you have the pickoff points adjusted
properly, you do not need to change them unless you
move the sensors or spray guns. Pickoff points can
be hidden once they are set, as described in
Configuration.
1. Enter Configure controller mode.
2. Go to the RESET Enc Measure menu.
3. Press the OK key to enter edit mode.
4. Press the Select+ key to reset the values.
5. Hang a test part on the conveyor, ahead of the
photoeyes. Have another person stand behind
the first bank of spray guns to tell you when the
part reaches them, while you watch the Measure
value.
6. Start the conveyor and note the Measure value
when the leading edge of the part reaches the
spray guns.
7. To determine the pickoff point for any other
vertical banks of spray guns, either repeat this
procedure, or measure from the first bank to the
second and add the distance measured to the
pickoff point for the first bank.

Calculating Lead and Lag Values
Value Description Positive or Negative Values
Lead Lead is the distance from the
spray guns to the leading
edge of the part. The lead
value can be positive or
negative.
Positive Lead: Setting the lead to a positive value turns on the
spray guns before the leading edge of the part reaches them.
Negative Lead: Setting the lead to a negative value turns on
the spray guns after the leading edge of the part reaches them.
Lag Lag is the distance from the
spray guns to the trailing
edge of the part. Lag values
can be positive or negative.
Positive Lag: Setting the lag to a positive value turns off the
spray guns after the trailing edge of the part passes them.
Negative Lag: Setting the lag to a negative value turns off the
spray guns before the trailing edge of the part passes them.
Spray Patterns
Spray Pattern Description
Restricted Both the lead and lag values are negative. The spray guns turn on after the leading
edge of the part passes them and turn off before the trailing edge passes them. This
pattern prevents or limits powder wrap around the edge of the part.
Extended Both the lead and lag values are positive. The spray guns turn on before the leading
edge of the part passes them and turn off after the trailing edge passes them. This
pattern allows powder to wrap around the edges of the part.

Setting Trigger Points (contd)
Error Factor Effect on Spray Patterns
The triggering controller has an error factor of one
real-world unit. For example, if the controller scale is
inches, the error factor is one inch. This factor can
affect coverage if lead and lag values are not
calculated properly.
The lead and lag values you set apply to all parts
entering the booth. When setting lead and lag values
make sure to take into account the error factor.
For example, if both lead and lag are set to -2 inches
and parts five inches long or less are placed on the
conveyor, they will not be coated. The lead and lag
values subtract four inches from the length of part
and the error factor subtracts the remaining inch,
leaving a zero length to coat.
