4 START-UP CHECKS
Before performing the start-up checks, be sure that you have successfully
completed the installation steps outlined in section 3 of this manual.
1. Disconnect the Connector from the X1 receptacle.
2. Check the resistance between the Automatic/Manual and Up/Down switches
using an ohmmeter.
Place one of the
leads of the
ohmmeter in pin
number:
Place the other
lead of the
ohmmeter in pin
number:
Then,
The ohmmeter display
should show:

3. Reconnect the Connector to X1 and set the lifter to Manual mode.
4. Apply the main power supply to the controller. The lifter must not move.
5. Verify the LED located on the front panel of the Controller.
6. Briefly push the Up/Down switch to the DOWN position. The torch lifter must
travel downwards for as long as the switch is pressed. Briefly push the Up/Down
switch to the UP position. The torch lifter must travel upwards for as long as the switch
is pressed. If the lifter direction of travel does not correspond to the Up/Down switch
positions, the field or armature connections of the lifter motor must be changed. Refer
to section 6 in this document for trouble shooting information.
7. Verify that the lifter travel limit switch assignments correspond with torch lifter
direction of movement by performing the following checks:
Move the Up/Down switch to the DOWN position and then trigger the
corresponding down travel limit switch by hand. The lifter should stop when the limit
switch is triggered.
Move the Up/Down switch to the UP position and then trigger the corresponding
up travel limit switch by hand. The lifter should stop when the limit switch is triggered.
Operate the lifter manually using the Up/Down limit switches. The lifter should
stop when it hits the travel limit switch. Then, you should be able to back-off of the
triggered limit switch by reversing the direction of the lifter.
8. Adjust the measuring system by performing the steps outlined in section 4.1 on
page 16 of this manual.
4.1 ADJUSTING THE MEASURING SYSTEM
To provide the proper amount of clearance, a high-frequency current is used to
determine the capacitance between the sensor ring and work piece. Due to varying
high-frequency cable lengths and sensor rings, you must fine-tune the measuring
system before performing a cutting sequence.
After replacing a high-frequency cable or sensor ring, re-adjust the measuring
system using the steps outlined below.
To adjust the measuring system, perform the following steps:
1.
Check to be sure that the measuring system is completely installed and
correctly wired. Double-check to be sure that the:
HF100 is connected to the sensor ring components by way of the appropriate HF
