This document is intended to assist with the setup of a vacuum-confirm switch used by HEGLA loading systems.
1) Clean all suction cups and check for damage. Push the lips of the cups back and look for cracks or rips.
2) Make sure that the angle of the Suction Frame (controlled either pneumatically or electrically, depending on age of Gantry) appears to be parallel with the angle of the glass on the rack.
3) There is a “Vacuum Confirm” switch located on the top of the Suction Frame. The green indicator on the back of the Suction Frame indicates that vacuum has been reached (solid green light) or that vacuum has started (flashing green light).
4) The Vacuum Confirm switch may require adjustment if there are problems with reaching vacuum on smaller size glass sheets (84x72, etc.). There is a small screw located on the Vacuum Confirm switch that can be adjusted to a range of -0.2 Bar to -0.8 Bar.
5) Testing of the Vacuum Confirm switch can be done with the use of a quantity of thin metal plates large enough to cover the suction cups. For example, if there is a problem reaching vacuum on smaller size glass sheets-
a) Enable the remote control,
b) Drive the Gantry to a position where the Vacuum Confirm switch can be accessed and where falling metal plates would not damage something,
c) Use the remote control to activate the Vacuum function,
d) Place the metal plates on the problematic suction cups (an 84x72 sheet, for example, may only use 4 out of 12 suction cups)
e) Adjust the Vacuum Confirm switch screw so that vacuum is reached when the problematic suction cups are covered, but NOT reached when no suction cups are occupied.
f) Testing of all applicable glass sizes should be performed anytime the Vacuum Confirm switch is adjusted.
