ADVANCED SETUP: PROCEDURE FOR SM-4/6, FG, SP-4D

RECALIBRATING YOUR UNIT

WARNING: ONLY AN EXPERIENCED PERSON SHOULD DO THE ADVANCED SET-UP. IMPROPER SETUP MAY CAUSE DAMAGE.

1. To view the advanced setup use one of the following methods:
a) Press the F2 key while turning the power on.
b) If the power is on, press the "C" key (reset key) and hold it, press the F2 key and hold it, then release the "C" key first and the F2 key second.
c) If a memory error has happened, the setup menu will appear automatically.

During the advanced setup, the operator can press"C" to return to the main menu immediately without going through the rest of the setup. The previous part of the setup will remain in the memory.

This PAGE contains the factory default settings

2. Enter the password:

The default password is zero (0) when machine is shipped. It is recommended the setup person change the password from default to protect from tampering. The password can be up to 6 digits .

3. Change the operation mode:

The operation mode (COUNTER, EYE, ONE SHOT WITH EYE) is decided by the machine inputs. The operator can only view or modify an operation mode for which the machine is equipped.

4. Accumulation counter:

The accumulator register stores the number of cut pieces. It will keep adding until it is reset. The maximum number displayed is two (2) billion. Follow the instructions when scrolling to reset (clear to zero) the accumulator.

5. To Calibrate the cut length:

By cutting the longest length that you can precisely measure and comparing it to the set length, you can improve the cutting calibration. Example: Cut a piece 24.000 long, it measures 24.375, recalibrating is done by typing in 24.00 at "SET LENGTH' prompt and 24.375 at "ACTUAL LENGTH". Repeating the procedure insures the closest accuracy.

6. Set high speed:

The high speed is the maximum speed of the step motor can go and is rated in steps per second (s/s). The step motor always accelerates from low speed to high speed and decelerates from high speed to low speed before stopping. The higher the running speed, the less torque the motor has and vice versa. So the maximum speed setting depends on the pulling force required to move the material, the range available is 1000 to 5800 steps per second. For your convenience the actual speed will be displayed in inches/sec.

7. Set knife-down dwell time:

The dwell value determines how long the knife solenoid should stay on. If the knife completes the cut, the shorter the on-time, the more product that can be run. The time interval is set in milli-seconds (ms).

Note: If the timer is set to zero (0), the knife solenoid will be disabled (0=dis. on the display), the knife will not operate at all.

8. Set knife-up dwell time:

On a standard machine, the web advance is controlled with the knife home sensor. If additional waiting time is necessary the knife-up dwell timer can be set in (ms). The timer starts counting after the knife solenoid is deenergized. Normal setting is (0) zero.

9. Set acceleration slope:

The slope value controls how fast the motor accelerates from low speed to high speed and decelerates from high speed to low speed. The select range is between 2 - 20. The smaller the value of the slope, the faster the motor will accelerate and decelerate. Most equipment is set at 2.

10. Set deceleration value:

The deceleration value is the amount of movement from high speed to low speed the motor makes before stopping. It is important to have some movement at low speed before the motor stops because it tightens backlash and improves accuracy. Generally a value will be at slow speed. Therefore 1000 steps is a good setting. By carefully listening to the motor you can hear this.

11. Set low speed:

The low speed is the minimum speed of the step motor. Normally, it doesn't need to be changed. The normal speed range should be between 500 - 1200 steps per second (s/s)

12. Motor Dir.:

Changes the direction of the stepper motor to clockwise or ounterclockwise as needed.

13. Set jog speed:

The jog speed is the speed when 'F' key is presses. The normal range of the speed should be 500 to 1200 steps per second (s/s).

14. Set the knife home sensor timer:

After the knife cuts, it normally will take 100 to 500 milli - seconds (ms) for the knife to move back to home position (knife home) . If the knife home sensor doesn't reset within the timer delay, a system error occurs and the operator must reset an alarm so the cycle can continue. Therefore the time delay should be set longer than the time that the knife takes to return to the home position. A setting around 1000 mili-second (ms) is recommended.

Note: If the timer is set to zero (0) the knife home sensor will be disabled

(0 = off, on the display), the operator may need to set a proper knife up dwell timer to make sure the knife goes home.

15. Set the product eye time delay:

When the product eye doesn't detect the material, the machine will pause to wait for material in a preset (via the keypad) time delay. If the eye detects the material within the time delay, the machine will continue the cycle automatically. If the eye doesn't detect the material after the time delay, the alarm will be on and the operator must reset the alarm before the machines can continue the cycle. The set number is approximately in milli-seconds (ms).

Note If the timer is set to zero (0) ,the product eye will be disabled

(0 = off, on the display), machine will keep going without checking material.

16. Set the jam eye time delay:

When the jam eye doesn't detect the material at the end of feed, the machine will pause to wait for material in a preset (via the keypad) time delay. If the eye detects the material within the time delay, the machine will continue the cycle automatically. If the eye doesn't detect the material after the time delay, the alarm will be on and the operator must reset the alarm before the machine can continue the cycle. The set number is approximately in milli-seconds (ins).

Note: If the timer is set to zero (0), the jam eye will be disabled

(0 = off. on the display), machine will keep going without checking material.

17. Set the end of cycle signal duration timer:

When the knife finishes cutting, the second output (out #2) will send a signal to indicate the current feed and cut cycle is finished. It is especially useful when the operation is in the ONE SHOT mode. The duration of the signal is set in milli-seconds (ms).

Note: If the timer is set to zero (0) ,the signal will be disabled (0 = off, on the display), no output will occur.

18. Set the unit of measurements:

Select a display in inch, foot, millimeter or meter.

19. Set current counter direction

Select the current counter either count down or count up. The default is count down.

20. Change the password:

Be sure to remember the new password.

21. Wiring instructions four-wire "one shot"

Set software to one-shot mode, by proceeding into the advanced setup by depressing C + F2 on the display panel.

With unit OFF and UNPLUGGED connect output dry contact signal lines white (input) and black (output) to your equipment. You can use D.C. (1.28VDC) voltage or A.C. (1-24OVAC) voltage. The white wire can then be connected to the (+) terminal from the power source and will go through the dry-contact relay.

One-shot input signal wires are colored green and red; when connected it will give the index signal to start the unit. A dry contact is required to give this index signal.

In advanced setup, you must specify a time for END SIGNAL TIMER; this time specifies how long the end signal output to be "ON". Setting the timer to zero, causes no end output to be produced, and will in essence be "OFF". The time is set to zero from the factory.

Given that the end signal timer has been set, for example to 1500 mill second (1.5 seconds), the unit will give an end signal output for 1500 milliseconds (1.5 seconds) after the total number cuts or feeds have been made.

Also, in advanced setup, after the selection is made to use "one shot" a prompt will appear which will ask for sequencing:

feed--> cut

1-CHANGE E-CONT

To have the unit feed material then cut on signal, press "E" to continue, If the desired sequence is to cut then feed and wait for the next signal, press "1" to change. Once the sequence is selected a new prompt will appear:

Batch Option OFF

1-CHANGE E-CONT

Enabling the batch option will allow the operator to run multiple cycles from a single input single. Normal operation is batch option - off which cycles once per signal. To continue through advanced setup press "E" Or to return to the main screen and menu press "C".
