ARM – Auto Recovery Module (Optional)
The Auto Recovery Module (ARM) is an optional memory module that is installed between the node and
the valve adapter module and is used to preserve the manifold configuration settings even during
catastrophic failure. During the power-up process it reads the configuration of the manifold, including any
user settable parameters of I/O modules, and stores the information in its non volatile memory. Once the
information is stored, it automatically disconnects itself from the power circuits while still mechanically
attached to the manifold. Upon power-up it reconnects itself and compares the stored configuration
settings to the actual manifold configuration. If these settings are different it gives the user the option of:
1. Updating the manifold setting with the stored values
2. Updating the ARM module with the current settings
3. Continue operation with present configuration without updating ARM
