Manual Safety Override Mode

For machines with CE safety circuit switches enabled, the Manual Safety Override mode allows the enclosure doors to be opened when the system is in Manual mode so the operator or supervisor can perform limited manual machine operations.

While the doors are open, manual jog feed is restricted. The jog feed is limited to 2 meters per minute, or approximately 80 inches per minute, with manual safety override enabled. No jogging is permitted with manual safety override disabled.

Manual operations that cannot be started with the doors open, regardless of manual safety override mode, are:

•Spindle On

•Park Machine

•Warm Up Machine

•Calibrate Machine

•Spindle Orient

•Chip Removal

•Tool Changer Functions

When the Manual Safety Override mode is enabled, it remains enabled until control power is turned off, the Emergency Stop button is pressed, or machine power is turned off. A fault will disable the Manual Safety Override mode also.

If you try to jog the axes with the doors open without enabling the manual safety override mode, a prompt appears to cycle the keyswitch or enter the access code to enable jog.

Using a non-numeric key cancels the operation.

When the code is successfully entered, the Limited Manual Operations feature is enabled, as indicated in the status field.

For initial setup of the Access Code, the user is prompted to enter a new code and then to enter the same code a second time before it is accepted.

  1. Select the Change Access Code softkey. A message appears asking you to enter the current code.

  3. Enter the new code. A message appears asking you to re-enter the new code for confirmation.

    1. If the new code is not re-entered, the code is not changed.

    2. When the new code is verified, the code will change and a message appears to confirm the action.
