This is the hydraulic pump assembly, located inside the right A-frame and cabinetry. The fluid
is DTE-26 or equivalent @ 1.2 gal stored in the reservoir that has a vent installed. There are no
filters in this system so keep the vent in place and fluid as clean as possible when handling or
changing same.
The motor is powered by 115 VAC or 220vac depending on site configuration.
The lowering solenoid, located on the pump housing, can either be 115 or 220 VAC again
depending on location power supply. The pump assembly is located between the drive motor
and fluid reservoir.
Raise is accomplished by motor powered up, pressure is regulated at 1100
PSI. A check valve allows flow out, through the flow control, through each sides raise control
regulators.
Lowering speed is controlled by backflow regulator that is factory adjusted but can
be adjusted in field.
The flow dividers function is to control even fluid flow to both raise cylinders. This is
accomplished by having one entry/return port that drives a mechanical spoon internally that in
turn only allows equal flow to each respective cylinder. Neither side can go faster since the
spool turns only by input flow.
Regulators on the flow divider are factory set and should not be tampered with. There are not
maintenance functions internally. Do not adjust anything since this will destroy the factory
default setting. Flow control valves can be adjusted in the field if required.
1-5B Lowering
When the operator clicks on “LOWER” icon, it sends a signal to motion computer initiating
lower action. Computer sends a relay signal to lower relay in power box that activates the lower
solenoid located on the pump housing. This, allows hydraulics to flow back into the reservoir.
Hydraulic pressure raises the unit however gravity, brings the machine back down.
.
1-5C Stop
STOP is a command given by:
a. Operator sent to motion computer that stops designated motion function.
b. The e-stop switch, located under operator monitor, removes all three phase power,
thereby stopping any/all motion. Power off brakes engage.
1-5D Pitch and Roll
Roll/Pitch
CPU program commands motion via motherboard to PCI Pro Motion card, to the motion
interface board, via pre formed cable, then to respective frequency drive unit. Serial
communication’s, is via a Blantronics PCI mounted card is used to monitor condition of inverters.
Rs-485 communication side, can be used to force drive of pitch/roll inverters under certain
conditions.
