Powering with an Edwards Porta-Power
Your Edwards Porta-Power 5hp / 3000psi / Portable Power Unit will
power all your Edwards Hydraulic Accessories.
Follow electrical connection installation instructions as set forth within
these sections of the Installation Manual:
With the Edwards Porta-Power off, install accessory hoses, power and
control.
Assure your M12 connections are seated properly. Align
M12 male and female fi ttings so that keyed surfaces align. Mis-
alignment of surfaces will prohibit correct operation.
• Install the male and female Horizontal Press hydraulic hoses to
the Porta-Power male and female quick connect hydraulic fi ttings
adjacent to the starterbox. Both fi ttings have a detent ball setting
that must be aligned to couple and uncouple hoses.
• Remove the safety cap at the push button port. Attach the Horizontal
Press hand control, male mil. spec. control cable to the female
mil. spec. accessory push button port on the Porta-Power case.
Attach the yellow limit switch cable to the limit switch port of the
Porta-Power. Attach the yellow Auxiliary cable to the 24V port on
the Porta-Power.
With all Ironworker and Horizontal Press stations clear of hands,
tools, tooling, material or debris, power up the Porta-Power by
depressing the green button on the starter box.
With the power on, your Horizontal Press is in a neutral position.
Test the Horizontal Press operation by pressing the OUT control button.
Once pressed, the cylinder will extend. Releasing pressure on the OUT
control button will stop the cylinder. Test the Horizontal Press operation
by pressing the IN control button. Once pressed, the cylinder will be
retracted back into the cylinder enclosure. Releasing pressure on the IN
control button will stop the cylinder.
Test the digital encoder and limit switches by rotating the scale crank.
Press the red e-stop button on the hand control to kill power at the Porta
Power. To reset power, twist the e-stop button and push start button at
Porta Power.
When disconnecting your Horizontal press, simply reverse procedure.
Replace the safety cap at the push button port to restore power to
