2.4 Putting into operation
2.4.1 Switching on the LOGO!/Power On
LOGO! does not have a power switch. The reaction of
LOGO! during startup depends on
Whether a circuit program is stored in LOGO!
Whether a program module (Card) is inserted
Whether this is a LOGO! version without display unit
(LOGO!...o)
The status of LOGO! at the time of power failure.
All possible reaction of LOGO! are described on the
following page.
To ensure that the expansion module on the LOGO!
changes to RUN mode, check the following:
Has the sliding contact between the LOGO! and the
expansion module snapped into place properly?
Is the power supply connected to the expansion
module?
In addition, always ensure that you switch on the power
supply to the expansion module first before activating
the power supply to the LOGO! basic module (or
activate both power supplies at the same time); if you do
not do this, the system does not detect the expansion
module when you start up the LOGO! basic module.
