PROGRAMMED DIAGNOSTICS FOR SE-2PTD

Some simple diagnostic tests are available in the program, by using the Hand Held Terminal.

These require using the “Shift” key on the keypad: refer to the keypad character map for shifted

characters, to use these commands.

If the machine is a DUAL FUNCTION SE2/4-PD or SE2/4-PTD, change function to the PIPE

PROGRAM to perform the following tests.

Press “

T” for Test

The display should show “D-E-F?”

Next press

D to check Drives

E for Encoders

F to Finish; get back to main menu

After selecting either D or E, for Drive or Encoder, the display will show “Axis No.”

Press

1 for Axis 1: rotation, or 2 for Axis 2: longitudinal motion.

If

Drive was selected, the corresponding axis selected should run

1 second forward ( display will show ‘F’)

1 second back

( display will show ‘B’)

The drive should move at the speed set by the speed pot, regardless of whether encoder pulses

are being counted.

If

Encoder was selected, the encoder count of the corresponding encoder (1 or 2) should scroll

up continuously in the display. Press any key to stop.

Rotating the encoder in either direction will increase or decrease the displayed count, if

the computer is successfully counting the pulses from it. The encoder can be rotated

manually if disengaged, or by using the joystick to move in the desired direction.

Note: the count is in hexadecimal notation (number base 16),

(10 H=16 decimal, 400 H = 1024 decimal).

1 rotation of the encoder corresponds to 400 (HEX) counts

Program Version:

Press “

V” to determine the Version. No.; e.g. SE041, which will show on the display.
