Operating the Control
2-20
Turn off power to the control when it is not used for an extended period of
time.
To turn off power to the control:
ATTENTION: To prevent damage to the machine, never turn
off power while a part program is being executed. Before
turning off power, make sure that the control is in CYCLE
STOP.
1. Press the <EMERGENCY STOP> button.
2. Make sure that power is turned off to all peripheral devices (tape
reader, tape punch, etc.) that are connected to the control.
3. Press the power <OFF> button.
The control assumes a number of initial operating conditions at power-up
or at a control reset operation (see page 2-18). These are:
Initial Password Access is to the level that was active when power was
turned off (provided that level is a power-up level selected in access
control). If the active level when power is turned off is not a power-up
level, the control defaults to the next lower level that is a power-up level
(see page 2-23 on access control).
The control is placed in E-Stop. The control is not allowed to come out
of E-Stop if the default AMP is loaded at power-up, or if there is no
PAL program loaded in your system. If either of these is the case, an
appropriate error message occurs.
