These two settings control the optional chip conveyor. Setting 114 (Conveyor Cycle Time) is the interval that the conveyor will turn on automatically. Setting 115 (Conveyor On-Time) is the amount of time the conveyor will run. For example, if setting 114 is set to 30 and setting 115 is set to 2, the chip conveyor will turn on every half an hour, run for 2 minutes, then turn off.
On-time should be set no greater than 80% of cycle time. Note the following:
The CHIP FWD button (or M31) will start the conveyor in the forward direction and activate the cycle.
The CHIP REV button (or M32) will start the conveyor in the reverse direction and activate the cycle.
The CHIP STOP button (or M33) will stop the conveyor and cancel the cycle.
