Verifying Feature Operation
The iQ ES generator can be congured with several features that provide
interfaces from the control board to encoders and transducers outside the
system. These features include the following:
• Distance Encoder
• Power
• EPR (electronic pressure regulator) with Pressure Transducer
• Force Transducer (Load Cell)
Each of these features has a corresponding output on the iQ Explorer's
Cycle Data page. The Cycle Data page allows you to see the last cycle of
a control/monitor parameter. In order for values to appear in the computer
display, the system may have to be cycled or manipulated in some way.
Distance
To verify the distance feature, go to the Utilities page of iQ Explorer. Put
a check in the box (p) for Monitor Encoder Position in order to view the
encoder position.
To check encoder function, either remove air pressure from the press or
depress the Emergency Stop switch that is grouped with the activation
switches.
As the thruster head moves up or down, the displayed value changes. The
value should increase as the head travels down and decrease as the head
travels up. On power-up, the reference mark (distance value) internal to the
iQ generator is set between - 0.03 inches to - 0.10 inches.
This means that only after the head passes the reference mark, will the
distance data from the iQ generator be useful as it relates to the phases of
the weld cycle.
