Option 3 – Keypad Input Mode
7.4
This mode is for verifying the function of the keypad. The display will look like the example below in
Figure 23. On the top line of the display, the letters represent the "row" position of the button, and the
numbers represent the "column" position. When one of the buttons on the keypad is pressed, the
corresponding "0" below the row and column values will a change to "1".
For example, pressing button "5" will change the display to the example shown in Figure 24, where "B"
is the second row down on the keypad, and "3" is the third column from the left.
Pressing the "Stop" button will briefly show a "1" in row "D" column "7", then you will exit this
diagnostics mode.
Option 4 – Feed Mode

This mode allows running of the folder, moving of the fold tables and firing of the feed clutch. While in
this mode, the Feed Table Load Position switch is disabled.
In this mode, all safety interlock switches (fold table present switches and top cover closed
switch) are disabled. The main motor can be run and the fold table drives can be run. Do not
place any loose items such as hair or hanging jewelry into or near the rubber rollers. Also keep
hands and fingers clear of the rollers at all times. Entanglement and injury will occur.
The buttons listed below are enabled and perform the following functions;

RUN – Toggles main motor on and off. If Feed Clutch solenoid is on, pressing the "RUN" button will
turn off the Feed Clutch solenoid prior to the Main Motor starting.

SPEED – Allows changing of speed in normal manner

STOP – If the Main Motor is running, this button will stop the Main Motor. If the Main Motor is not
running, pressing the "STOP" button will exit this diagnostics mode.

If Main Motor is running, the Feed Clutch fires in one-shot manner each time the "TEST" button is
depressed.

ENTER – Starts the Main Motor and then fires the Feed Clutch once every .5 seconds. The folder
will continue to run and fire the Feed Clutch until the "STOP" button is pressed. It's important to
adjust the Retarder down (away from the Feed Wheel) prior to pressing "ENTER". This will prevent
any possible damage to the Feed Wheel or Retarder.
