500 volts, it may be necessary to move the wires from the 220 to 200-volt tap. You should also place the
primary side wires on the 480 taps.
In the case of 415 volts, it is better to place the wires on the 400-volt taps as the output voltage will be
closer to 230 volts.

Air Connection
Connect the air supply to the quick disconnect coupling to the left of the pressure regulator and beneath
the in-
line air switch. The air supply line should have a minimum of ½” inside diameter. It is
recommended that a water separator or air dryer be installed upstream of the TMC air supply. Connect

Air Regulators and Solenoids
The TMC consists of 2 air regulators, 3 air flow valves and 3 solenoids that need no adjustment. They are
all set at the factory but should be checked upon installation.
The main air regulator for the machine should be set at 90 psi and the secondary one that supplies air to
the spindle cartridge should be set at 7 psi. These regulators are adjusted by pulling the cap upward and
rotating the cap clockwise to increase the air pressure and CCW to decrease the air pressure.
The 3 air flow valves should be set at the factory but can be checked as follows. For the valve that
controls the flow of air through the spindle during a tool change, close this valve and open it 6 or 7 turns
and then lock it in place as shown in figure 2.9.1a. For the other 2 valves that control the speed by which
the ATC moves in and out, they should be opened all the way and locked in place as shown in figure
2.9.1b.
