1.
Turn off fluid flow using pendant button and turn off power to the TMC.
2.
Loosen the slide cap and unscrew the captive screw at the top of the sensor. Now you can slide
the cap out of the way. See figure 7.6
3.
Disconnect two small electric ferrules on the sensor and remove the wires then loosen the sensor
with a wrench. Replace the old sensor with the new one
4.
Reverse above steps to reconnect the sensor.
5.
If the spindle has a tool in it, remove it for calibration and power up the TMC turn on CTS at the
pendant.
6.
Note the adjustment screwdriver in the top center of the sensor for calibration. Use a flat blade
to tighten this screw slowly, approximately 1/8
th
of a turn a second. When machine faults out,
loosen the screw ¼ turn and clear the fault on the pendant.
7.
Test CTS pump to make sure it comes on and operates for at least 10 seconds without faulting.

CTS Remove and Replace Pump
Steps needed for the replacement of the CTS Pump see figure 7.0 for location:
Warning!
Heavy object to be installed, proper safety precautions are needed.
1.
Turn off CTS fluid flow at the pendant and turn off power to the TMC.
2.
Drain enough coolant to clear the filter canister. Disconnect the wires going to Coolant Pressure
Sensor connector (refer to section 7.6) and Filter Clog Sensor connector (refer to section 7.4).
Disconnect power supply cover and cable from the motor. Protect the wires from fluid possibly
coming from outlet hose. Disconnect filter hose.
3.
The filter assembly (with sensors attached) can then be removed from pump outlet.
4.
Remove four SHCS screws that bolt the motor to the sheet metal base. There are four nuts close
by which connect to the internal impeller assembly, do not remove them. You want to remove
the impeller with the motor.
5.
This pump and impeller assembly weight about 100 lbs., use a proper lifting device for this step.
Connect hoist to motor and lift off TMC. Slowly lift assembly from housing to let the impeller
drain thoroughly. Set down in a safe manner.
6.
Use the hoist, carefully guide the new motor assembly into position and reconnect the four SHCS.
7.
Reconnect the electric supply cable with cover, filter assembly, filter outlet hose, and two
sensors. The sensors do not need recalibration.
8.
Power up the mill, turn on CTS at the pendant and test motor operation. Verify motor is turning
in the correct direction with the arrows on top of the pump that indicate correct fan direction.
