TI545/TI555 System Manual
Check AC input power for proper voltages. Ensure that the jumper
in the back of the power supply is set for the correct voltage.
Ensure that all I/O interface cables are properly connected to I/O
interface connectors.
Ensure that all configured bases are properly connected, there are
no crimps or breaks in the cable, and base addresses are correct.
3. If you intend to use an EEPROM (EPROM), install the EEPROM
(EPROM) according to the instructions given in Chapter 5.
4. Initialize the CPU by completing the following procedures:
If you have not already done so, disable the CPU battery by
turning off switch 9 on the dipswitch. Ensure that a programmed
EEPROM (EPROM) is not installed.
Turn on power to the controller.
With the battery disabled and no programmed EEPROM (EPROM)
installed, the CPU clears memory and enters PROGRAM mode.
Enable the battery backup circuit by turning on switch 9. The
Battery Good LED should light. The CPU is now initialized.
NOTE: If the battery LED does not come on, the battery may be discharged.
The LED should light when fully charged with the switch enabled and
power applied. A blinking light means marginal charge. The battery will be
fully charged after 24 hours of operation.
5. Connect your programming device to one of the CPU communication
ports. Place the CPU in PROGRAM mode. If you have installed a
pre-programmed EEPROM (EPROM), go to step 8.
6. Using your programming device, enter the memory (refer to Table 6-1
and Table 6-2) and I/O configuration.
7. Enter the user program. See the SIMATIC TI505 Programming
Reference Manual (PPX:505–8104) for programming information.
8. Use your programming device to JOG motors, solenoids, or other
positioning devices one at a time to establish correct rotation or
positioning.
After all the steps are performed and verified, place the controller in RUN
mode.
