Hc4672N - LEGRAND 3440 Technical Sheet

2-module flush-mounted actuator 16A
Description
The device is an actuator with 1 bistable relay sensor with local pushbutton for load
forcing/local control for the Automation and/or Load control management functions.
In load control mode:
The actuator will be given a priority indicating the tripping order that will be followed
by the F521 load control central unit (e.g. Priority 1 will be the first load disabled if the
threshold is exceeded). This priority coincides with the address that will be used in all
the configuration software programs. Using the forcing pushbutton it will be possible to
re-enable the load for 4 hours after DISABLING by the central unit, or remove the load
forcing previously set.
In automation mode, the actuator can perform the following functions:
- All operating modes that can be configured on the control devices, with the exception
of those requiring the use of two interlocked relays;
- Possibility of group configuration (G)
- Additional modes using the M configuration socket.
In mixed load control and automation mode, the following rules are followed:
The local button performs the load control management function (forcing/end of forcing)
- If the load is ENABLED or FORCED, the status of the relay follows the commands of the
Automation system.
- If the load is DISABLED by the load control central unit, the status of the relay does
not follow the commands of the Automation system, but can only be re-enabled by a
command, ENABLING or FORCING, from load control management.
During disabling, the actuator keeps the statuses requested by the Automation
commands in memory. After RE-ENABLING the relay is placed in the status required by
the last automation command.
This function has been conceived for applications where the load control management
function is implemented, with the need, via automation commands, of performing
hourly load scheduling. If during the DISABLING stage the relay is switched OFF due to
the scheduling settings, when re-enabling takes place it will stay switched OFF.
The bistable relay enables preserving the status of the load even if there is no voltage on
the SCS BUS (and subsequent device reset).
The device consists of 2 modules, so that it can be installed in supports of the Living,
Light, Light Tech and Axolute series, and is provided with a bay for 6 configurators: A,
PL, G, M, P1, P2.
