A 24 V
DC
voltage supply is available at X4 which is derived from the line
voltage by the power unit.
Power supply by the internal 24 V
DC
voltage generator and thus the
operativeness of the devices supplied by it is ensured only if line
power is supplied to to the line input of the power unit!

" When using the internal 24 V
DC
voltage generator, the following
notes should be observed:
• For technical data, refer to page 311.
• For power supply to control logic:
When the line voltage is switched off at the line input of the power
unit, the timer is also turned off. In this state
• programming, diagnosis or visualization via the timer, and
• communication are no longer possible between the timer and
the PLC/robot.
• For power supply to the I/O module:
When the line voltage is switched off at the line input of the power
unit, the I/O module is also turned off. In this state
• communication is no longer possible between the timer and
the PLC/robot via the discrete signals.
"
If these conditions are not suitable for your application, the 24 V
DC
supply to the timer and/or the I/O module must be provided by
external power supply units!
