The only control available for the wet table is the hand control, which is used to raise and lower the work surface.
The location to connect the hand control to the table is on the top left side of the column.
The hand control has continuous current flow that travels to the control box through separate wires.
When a direction is selected, the signal voltage is interrupted. This sends a signal to the control box activating the actuator, lifting the work surface up or down.
When testing components with power on use care to prevent electrical shock.
Hand Control Test
