•
A hardware module is replaced by the same type of hardware module, in the same position.
•
Two of the same type of hardware modules swap position.
•
An extension rack is replaced with an extension rack with identical hardware.
Factory settings
The hardware configuration for each controller is created in the factory. If the hardware is changed, the controller activates a
Fieldbus conflict
alarm. The controller hardware configuration must be confirmed in PICUS.
When a new extension rack is connected, the controller always activates a
Fieldbus conflict
alarm. The extension rack hardware
configuration must be confirmed in PICUS.

13.4 Power supply module PSM3.2
13.4.1 Power supply module PSM3.2
The power supply module provides power to all the hardware modules in the extension unit and communicates with the main
controller through the internal communication ports. The rack status and alarms activate the PSM's three relay outputs. There are
two ports for internal communication with the main controller.
PSM3.2 manages the hardware module self-checks for the rack and includes a power LED. The power supply terminals include
circuit protection against load dump transients and JEM177 surge transients (rugged design). These terminals also include battery
voltage measurement.
