8.1 M227/207-CW & M207-CW COOLING UNIT SPECIFICATIONS/INSTALLATION
5. Operation -
2. Both M227/207-CW & M207-CW contain flow sensors. Any time the CW
unit is turned ON a signal will be sent to the M-207A that indicates if the
flow is adequate If it is the M-207 STATUS screen (at power up) displays
COOL-OK. If it is not OK the screen will display COOL-FLT. Any time
there is a COOL-FLT the problem must be corrected in order to weld.
3. If coolant is not needed, turning the CW unit OFF will disconnect the fault
function. THE COOLANT FAULT ONLY WORKS IF THE CW IS
TURNED ON.
4. 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.
