Bticino actuator relay bistable with zero crossing F523

The device is an actuator with 1 bistable relay with zero crossing functionality intended for the functions of Load Control and/or Automation Management. The actuator is able, in isolated mode, to evaluate the frequency (50 Hz) and the voltage of (230 Vac).

In load control mode: the actuator will be given a priority that indicates the order of disconnection that the F521 load control unit will follow (e.g. Priority 1 will be the first load that will be disabled if the threshold is exceeded). This priority coincides with the address that will be used in all the configuration SWs. Using the forcing button it is possible to re-enable the load for 4 hours after a DISABLEMENT of the control unit, or to remove the load forcing previously set.

In automation mode the actuator is able to perform the following functions- all the operating modes that can be configured on the control devices, with the exception of those involving the use of two interlocked relays; - possibility of carrying out group configuration (G) - additional modes using the configuration seat M.

In mixed mode load control and automation the following rules are followed: The local key has the function of Load control management (forcing/end of forcing) -

• if the load is ENABLED or FORCED, the relay status follows the Automation system commands.
• if the load is DISABLED from the central load control unit, the relay status does not follow the Automation system commands but can be re-enabled only by a command, ENABLED or FORCED, from the load control management. While the disabling is in progress, the actuator keeps in memory the statuses requested by the Automation commands and at the RE-ENABLE the relay is put in the status foreseen by the last automation command. This function is designed for applications in which the Load Control Management function is implemented with the need to use automation commands to schedule the loads on an hourly basis. If the relay is switched off during the DISABLISHING phase due to a scheduling, it will still be off when it is reactivated.

The bistable relay allows the load status to be maintained even in the event of a power failure on the SCS bus (and subsequent device reset). The device has a footprint of 1 DIN module and has a housing for 6 configurators: A, PL, G, M, P1, P2
