Set-up / Start-up Procedure
Verify all electrical connections are made per Section 3 of this procedure. Ensure the
[Hand/Off/Auto] selector switch is set at Off. Turn main power on to the ECAT unit. The
Power On light on the MCC should be illuminated.
Check rotation of the motors by jogging the [Hand/Off/Auto] selector switch to [Hand].
The motor must rotate clockwise when viewed from the back of the motor.
Turn the [Hand/Off/Auto] selector switch, on the MCC, to the [Auto] position. The motor
will start-up and run.
Allow the Electric driven Hydraulic Pump (67) to run several minutes circulating fluid from
the reservoir through the System Bypass Valve (71) and back to the Reservoir (60) to
eliminate most of the air in the hydraulic lines.
With the motor running, slowly close the System Bypass Valve (71). Check Hydraulic
Pressure Gauge (79) to observe pressure build up in the hydraulic lines and fluid will start to
fill the Accumulator.
Observe the Level Viewer (62) to ensure enough fluid is present to fill the Accumulator (76). In
the event the fluid level drops to the trip point of the Level Switch (63), the Electric Motor (69)
will stop. Add fluid to the Reservoir (60) if needed.
Allow the Pump to run filling the Accumulator until the Thermal-Volume Controller moves
and trips the Motor Start / Stop Switch (78) stopping the Electric Motor.
Slowly open the System Bypass Valve (71) and relieve the pressure in the hydraulic lines until
the electric Motor starts to run. Close the System Bypass Valve. Allow the motor to run until
the pump fills the Accumulator and the Thermal-Volume Controller shuts the motors off.
Perform step 4.6.14. 3 to 4 times so that air can be worked out of the system. Allow the
Electric Driven Pump (67) to run until it is stopped by the Motor Start / Stop Switch (78).
Maintain this pressure for 5 minutes while visually inspecting the hydraulic system for leaks.
Corrective action must be taken for any leaks found.
Turn the [Hand/Off/Auto] selector switch to [Off].
Open the System Bypass Hand Valve (71) and relieve the pressure in the hydraulic lines.
Close the System Bypass Hand Valve (71).
