1 MACHINE DESCRIPTION
This manual describes the COLOMBI ORBIT with length test feedback, heater
and load testing.
The PLC controller is an Allen Bradley SLC500 with a 1000 color panel display as an
operator interface.
1.1
System Operator
The ORBIT test system is easy to use and requires no special user training to make minor
adjustments, such as modifying ejection times or changing probes. For making basic
adjustments, some commands are available directly from the control panel display, such as for
adjustment of length control and calibration of load cells.

♦ Connect air pressure: min. 5.5 bar–max. 7 bar
♦ Connect electrical power feed to system.
3.1
Interface for Spring Coiling Machine
ORBIT is started with an external signal from the line. ORBIT signals the coiling machine to
produce one spring and deliver it to the ORBIT.
The coiling machine is then set to the ready mode and awaits new signals from ORBIT (the
line).

4 SAFETY
To fulfill the safety requirements of the European directive 89/392/EEC and OSHA, these
machines are equipped with protective safety hoods and emergency stop buttons.
4.1
Emergency Stops and Safety Protection
4.1.1
Emergency Stop
If the emergency stop button is pressed or if the covering safety hoods are opened, the air
pressure is expelled and the servomotors stop.
4.1.2
Resetting After an Emergency Stop
The emergency stop button is reset by pulling it straight out. To reset the machine, press the
RESET button. Correct the problem in accordance with any error messages and then
acknowledge the error messages. Close the protective hoods and restart the machine.
It is possible to run the machine without the protective hoods if the key is turned to the
SERVICE position.
The machine will then be able to be run in the manual mode only (external signals are
blocked).
A machine that is delivered without safety equipment
many not be put into service until it has been built in to
system that fulfils the applicable regulations.

6.2.1
ORBIT TEST
The ORBIT TEST menu is used to adjust the load and length control, and for setting the
compression to OFF or ON. This mode permits manual operation of up and down movements
by the ORBIT head and indexing of the revolver.
Accessing this menu puts machine in cycle off mode.
Key must be in SERV position to enable use of some functions.
NOTE: After having returned to the menu MAIN MENU from ORBIT TEST and pressing
the button F1 CYCLE ON, ORBIT resets itself by emptying all of the revolver test sockets of
springs through the outlet for faulty springs. The revolver is then filled until two approved
springs are in the delivery position.

7 LOAD CALIBRATION
Choose the menu LOAD CALIBRATION.
When calibrating the load cell, the revolver shall be removed from ORBIT.
Removing the ORBIT revolver: Unscrew the revolver's center screw, lift up the lock washer
that is under the center screw and pull the revolver out from the side.
7.1
Check of Load Cell Installation
Check that the load cell is correctly installed and that it does not touch the hole in which it is
mounted. Check, using shims of about 0.1 mm, that there is space between the detector and
the hole in the plate. Check that no debris or other foreign matter has fallen into the space
between the load cell and the hole. If necessary, remove the detector and clean the hole.

7.2
LOAD CALIBRATION
LOAD CALIBRATION
To calibrate the load cell, two known weights are required. The heaviest should be 30% more
than the spring load to be tested. The lighter weight should weigh half as much as the heavier
weight.
During calibration, the load tester is adjusted for no- load and two known loads. If you choose
a heavier load of about 250 grams, the lighter load should be half as much, meaning 100-150
grams.
7.2.1
Calibration of Load Cell.
Calibration begins with the load cell unloaded. Check that the signal from the load cell has the
correct amplification at zero- load. The signal shall be about 10% and can be read on the scale
in the menu window. Any necessary adjustments to 10% are made with the potentiometer P2.
Sensitivity is adjusted with the potentiometer P1 on the amplifier panel (see Figure 1).
Press F4 and enter the value "0" grams.
Store the zero- load by pressing F5.

35107201
Place the heavier load (~250 grams) on the load cell.
Press F6 and enter the known value of the heavier load.
Store the heavier load by pressing F7.
When calibrating with the maximum load, you should try to attain as large a load signal as
possible, although not over 80%, at maximum load plus the tolerance. To make a rough
adjustment of the signal, use the switches (see Figure 1) on the amplifier panel. The lower the
number of the switch, the higher load signal attained for a given load. NOTE: If a switch
position is changed, zero- load calibration must be repeated. (See Section 7.2)
Check the function by removing the load; the scale should show 0 or very close to 0. Place the
weight on the load cell again. The indicated value should be close to the actual load value.
Remove the heavier load, place the lighter load (100-150 grams) on the load cell and check
that the display shows the correct value. (If an incorrect value is shown, check that the load
cell is not touching the plate on which the load cell is mounted.)
Calibration of load cell is now complete.
The load cell values are shown in the info box diagram both as percentages of the maximum
value and in grams.
F1 resets load cell.
