C-KEY INSTALLATION
The C-KEY is a storage device, used to save and restore the product
configuration. It must be removed or inserted only when the product power
supplies are OFF.
To remove the C-KEY, unscrew the two lateral screws, and then pull the
device upward, vertically. If needed, use the screwdriver as a lever, with the
help of the notches intended for this purpose at the base of the screw guides.
When installing a new C-KEY, be sure that the flattening is directed to the
rear of the product, then carefully insert the device in the opening, vertically,
and screw it.
ALARM CONTACTOR
The product provides an alarm contactor in order to signal a predefined event
to the user.
Power connector pins 5 and 6 are used to achieve this goal. This contactor is
open at quiescent state and closes when the alarm condition occurs. It is
closed as well when the product is powered off or not in an operational state.
This is a first stage alarm contactor which must not be used to drive power
directly. To realize this function, please consider the use of a power relay (as
shown by the picture below).
Moreover, neither surge nor ESD protections are provided in order to keep
correct insulation. Please use your own protection devices if needed.
The WLg-IDA/S contactor can switch a maximum voltage of 60V and a
maximum current of 150mA.
