STA SERIES AC CONTROLS
990-351 H-1
APPENDIX H
FORCE CONTROL OPTION
Description
The Force Control (Force Output) Option can
control up to 8 electronic pressure regulators.
Output Force is programmed in lbs using front
panel controls. Once the Operator programs the
Output Force, the Control converts this to the
correct voltage to be sent to the electronic
pressure regulator in order to get the desired
force.
Calibration is a simple 2-step procedure using
front panel controls.
Force Board
Operation
Descriptions of how to program and use the Force Control functions are located in Chapter 3, Using
STA Series Control Functions. For accurate back pressure readings, the electronic pressure regulator
attached to this board must be set to have an association of 0-10V = 0-100 psi.
Calibration
CAUTION: If the electronic pressure regulator
is set to have an association of
0-10V = 0-100
psi, Lo psi during calibration will be about 30 psi
and Hi psi will be about 80 psi. Make sure the
force gauge used can withstand the force of the
weldhead at 80 psi.
