Electric Displacement Control Adjustment
1. Install a pressure gauge in port MB to measure outlet pressure. Install a flow meter in outlet line to
measure pump flow.
W
Warning
Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin causing
serious injury and/or infection. Relieve pressure in the system before removing hoses, fittings,
gauges, or components.
Unintended movement of the machine or mechanism may cause injury to the technician or
bystanders. To protect against unintended movement, secure the machine or disable / disconnect
the mechanism while servicing.
C
Caution
Contamination can damage internal components and void the manufacturer’s warranty. Take
precautions to ensure system cleanliness when removing and reinstalling system lines.
2. Start the prime mover and input 700 mA to electric displacement control solenoid valve, then allow
fluid to reach normal operating temperature. The pump must be at full displacement at this point.
Danfoss recommends a prime mover speed of 1500rpm (unless specified otherwise).
The testing setup must be plumbed in a way so the EDC function works properly. Please refer to
Electric Displacement Control (E) Operating Instruction.
3. Totally lock the LS control (if used) to avoid interference with EDC adjustment.
a) Loosen the LS control lock nut and turn the LS control adjusting screw clockwise all the way to the
end, while holding the LS control adjusting screw.
b) Torque the control lock nut to 21.6~24.6 N•m [191-218 lbf•in].
