KEYPAD LOCK
– A function to exclude all modification to operating parameters can be enabled; measurement viewing is still provided in any case
– To lock and unlock the keypad, press and keep MODE key pressed. Then press the L key three times and the M key twice and after that release MODE
– 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:
• Operation between automatic and manual mode
• Access to set-up menus
• Change of cosphi set-point
– By attempting to conduct the above operations, the display will view LOC to indicate the locked keypad state.
EXPANDABILITY
– Thanks to expansion bus, the DCRL8 can be expanded with two EXP... series modules
– The supported EXP modules can be grouped in the following categories:
• Additional steps
• Communication modules
• Digital I/O modules
– To insert an expansion module:
• Remove the power supply to DCRL8
• Remove the protecting cover of the expansion slot
• Insert the upper hook of the module into the fixing hole on the top of the expansion slot
• Rotate down the module body, inserting the connector on the bus
• Push until the bottom clip snaps into its housing.
Expansion mounting
– When the DCRL8 is powered on, it automatically recognises the EXP 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:

IR PROGRAMMING PORT
– The parameters of the DCRL8 can be configured through the front optical port, using the IR-USB code CX01 programming dongle, or with the IR-WiFi code CX02 dongle
– This programming port has the following advantages:
• You can configure and service the DCRL8 without access to the rear of the device or having to open the electrical panel
• It is galvanically isolated from the internal circuits of the DCRL8, guaranteeing the greatest safety for the operator
• High speed data transfer
• IP54 front panel protection
• Limits the possibility of unauthorized access with device config, since it is necessary to have the CX01 or CX02 dongles
– Simply hold the CX.. dongle up to the front panel, connecting the plugs to the relevant connectors, and the device will be acknowledged as shown by the LINK LED on the programming dongle flashing green.
