SECTION 4, ELECTRICAL SYSTEM
This machine has been built to the customers requirements, however, if any voltage changes are required,
refer to the information on the following pages and then consult Hyd-Mech service department before implement-
ing any changes. The control panel layout is shown on the next page.
INITIAL START-UP
At initial hook-up it is important to check that the phase order is correct. This is indicated by the blade drive
wheel revolving in a counterclockwise direction and the hydraulic pressure gauge registering a pressure rise.
NOTES:
1)The PLC is equipped with a lithium battery to keep the program stored while the power is shut
down. The battery will need to be replaced every 3 to 5 years, depending on usage. A visual
warning will be displayed on the interface when the battery drains to a certain level. Battaries can
be purchased through your Hyd-Mech Distibutor.
2) If the machine is equipped with an inverter, do not turn disconnect on for 3 three minutes after
disconnect has been shut off. Cycling power sooner than 3 minutes will result in damage to the
Variable Frequency Drive.
3) All of the machines equipped with a Mitsubushi PLC have a snap on Ferrite core on the interface
cable. This is placed near the interface in order to reduce "noise".
4) Hyd-Mech also recomends that an earth ground be installed on this machine.
