Manual pump operation
1. Go to the CNC screen that turns on the pump manually (refer to the operation instructions for the CNC being used).
If the selection console shows coolant flow error 093, the pump must be turned on manually within 8 seconds of
turning on the power supply, or the power will have to be turned off and then on again.
2. Turn ON the power. Turn ON the pump manually, and allow the coolant to flow for 60 seconds.
3. Write down the coolant flow rate on the CNC screen. The recorded flow rate will be used for comparison during
some of the tests. Coolant flow must be greater than 2.3 lpm (0.6 gpm) for the system to operate.
Note: A flow diagram can be found on schematic 013374, sheet 19 of 24
