M227/207-CW & M207-CW COOLING UNIT SPECIFICATIONS/INSTALLATION
4. Installation
3. Before mounting the M277/207-CW or M207-CW on to the M-227 remove
the fill cap and add the water. Replace the fill cap. Remove the pins
attached to each corner post (see figure 9). Locate the CW Power Cord
exiting a hole in the top of the CW unit. Pull enough of the cord out so it
dangles over the side of the unit.
4. Move the M-227 onto the CW unit and insert the corners onto the posts
of the CW Unit. Locate the M-227 Coolant Unit Connector located on the
panel on the AC Input side of the M-227. Insert the CW cable connector
into the M-227 connector. Secure the CW unit with the pins that were
removed (figure 9).
5. Install the adapter cable coolant hoses per section III. Re-connect the M-227
power cable.
5. Operation
1. When all connections have been made per Section III and a coolant flow
path is created, turn the M-227 ON and set the CW ON/OFF
switch to ON. The pump should start circulating coolant.
WARNING
DO NOT OPERATE the water cooling unit WITHOUT coolant in the tank
OR WITHOUT a water flow path (water OUT to IN through a weld head).
2. Both CW units contain a flow sensor. If the Set Up Screen Coolant Fault
Mode is ON the M-227 will look to see if the Cooling Unit is connected. If
it is, the M-227 will require that coolant be flowing or else it will create a fault.
If for some reason the Cooling Unit is connected but not being used the
operator can change the Coolant Fault Set Up to OFF and no coolant fault
will be detected.
CAUTION
Severe damage to the weld head and cables can occur if you have the Coolant Fault turned
OFF and are operating a weld head that needs coolant and then you forget to turn the cooler
on or to make the connections.
3. The above is the basic operation. The only decision to be made is whether
COOLANT is required. Some weld heads need it, some do not, depending
on the type of weld and duty cycle. Consult with an AMI representative as
to cooling requirements.
