Installation and Maintenance
This chapter describes how to install the SLP into a Series 90-30 PLC rack.  There is also a
section describing maintenance considerations.
Selecting the Right Slot
The SLP can be installed in any unused slot in the CPU rack of the Series 90-30 PLC if the
following rules are followed:
1.
Configuration created by Logicmaster must match the physical location of the
modules. Configuration faults are logged in the PLC fault table.
2.
For the 90-30 SLP all the slots between the SLP and CPU must be occupied.  If any
slots between are empty the SLP cannot communicate with the CPU.  The SLP must
be in the main rack with the CPU.
Inserting the SLP
Follow these steps to insert the SLP into the Series 90-30 rack:
1.
Power down the Series 90-30 PLC system
2.
Locate the desired rack and slot.
3.
Slide the 90-30 SLP completely into the slot.
4.
Press down firmly to lock the module in place, but do not use excessive force.
5.
Power up the PLC rack.  The Status LED flashes during power-up diagnostics.  The
LED comes on steady when the SLP is ready for operations.
