The display will show LOC when the keypad is locked and UNL when it is unlocked.
•
When the lock is enabled, it is not possible to make the following operations:
•
o Operation between automatic and manual mode
o Access to set-up menus
o Change of cosϕ set-point
By attempting to conduct the above operations, the display will view LOC to indicate the locked keypad state.
•
8. Expandability
Thanks to expansion bus, the RPC 5LGA can be expanded with one expansion series module.
•
The supported expansion modules can be grouped in the following categories:
•
o additional steps
o communication modules
o digital I/O modules
To insert an expansion module:
•
o remove the power supply to RPC 5LGA regulator.
o remove the protecting cover of the expansion slot.
o insert the upper hook of the expansion module into the fixing hole on the top of the expansion slot.
o rotate down the module body, inserting the connector on the bus.
push until the bottom clip snaps into its housing.
o
When the RPC 5LGA regulator is powered on, it automatically recognises the expansion module that have been mounted.
•
The expansion modules provide additional resources that can be used through the dedicated setup menus.
•
The setup menus related to the expansions are always accessible, even if the expansion modules are not physically fitted.
•
The following table indicates which models of expansion modules are supported:
•
9. IR programming port
• The parameters of the RPC 5LGA regulator can be configured through the front optical port, using the IR-USB code
A25060046580008 programming dongle, or with the IR-WiFi code A25060046580009 dongle.
• This programming port has the following advantages:
o You can configure and service the RPC 5LGA regulator without access to the rear of the device or having to open the
electrical panel.
o It is galvanically isolated from the internal circuits of the RPC 5LGA regulator, guaranteeing the greatest safety for the
operator.
o High speed data transfer.
o IP54 front panel protection.
o Limits the possibility of unauthorized access with device configuration since it is necessary to have the IR-USB or IR-WI-
FI dongles.
