3. To copy a channel to another channel:
a. Press the CHANNEL SELECT button on the front panel of the
pattern controller to select a channel number (Copy CH1 - 4) whose
settings you would like to copy to another channel number.
b. Press the or button for the cursor to appear beside CH1.
c. Press the or button to go from CH2 - CH4.
d. Press the or button for the cursor to appear beside No.
e. Press the or button to change N to Y and this will copy the

Warnings
The pattern controller monitors warning conditions like:
Trigger 1 - 4 too short (clipping), T1- 4 max distance exceeded (jamming),
Ch1 - 4 short circuit, etc.
NOTE: Warnings appear in the display. They remain visible until they are
acknowledged by pressing any button.
The pins A, B and C at the remote output (refer to Page 22) are wired as an
alarm output. The alarm output can be used for a machine stop signal or to
trigger a remote device.
When a fault occurs, there are two cases in which the alarm output is
activated. In all other cases, only a warning appears in the display.
1. Short circuit of the gun output
2. The jam detector signals a fault

Fault Condition
A fault condition occurs typically when there is a hardware or software
defect. When a fault condition occurs, the user will need to take immediate
action.
Warning Condition
A warning condition alerts the user that there may be an error with the
setup of the pattern controller. When a warning condition occurs, immediate
action may not be required.

Encoder Scaling
This menu is used to display the encoder type and configure the encoder
scaling. The pattern controller automatically detects the type of encoder
installed. If no encoder is detected, the Not connected message appears in
the display.
The encoder scaling ratio is determined by entering the number of pulses
per millimeter that the encoder outputs when installed. If a quadrature
encoder is used, the direction of rotation travel maybe reversed.
Encoder Scaling
Encoder Single
Custom 1,000 ppmm
Direction Forward
O683
1. To set the encoder scaling
a. Press the or button for the cursor to appear beside Custom.
b. Press the or button to set the encoder gearing ratio from
0.1 - 20,000 ppmm (pulses per millimeter).
2. To set the encoder direction
Press the or button to set Direction to Forward or Backward.
NOTE: The direction parameter is used only if a quadrature encoder is
detected.
