Procedure
|
1 |
Locate the Motor Protecting Switch (S301). Press the operating handle down to position OFF. |
|
2 |
Make sure that the LED indicator L2 on the front of the 24 VDC power supply is lit. |
|
3 |
Locate Hoist/Lower Switch (S302). Set the switch to position HOIST. |
|
4 |
Make sure that Hoisting Contactor (K301) is not activated.
If Hoisting Contactor (K301) is activated:
|
a |
Locate Upper Limit Switch (S304) on the hull unit (inside the gantry, at the top). |
|
b |
Press Upper Limit Switch (S304) up to activate it. |
|
c |
Make sure that the Hoisting Contactor (K301) is deactivated. |
|
|
5 |

|
6 |
Verify that Lowering Contactor (K302) is activated. |
|
7 |
Locate Lower Limit Switch (S305) on the hull unit (inside the gantry, at the bottom). Press Lower Limit Switch (S305) down to activate it. |
|
8 |
Verify that Lowering Contactor (K302) is activated when you activate Lower Limit Switch (S305). |
|
9 |
