7. F 400: MANAGE THE RELAYS
When the transmitter is still in alarm state, the relay goes off and activates its negative or positive security according to its
configuration.
Three relays activation modes are available:
•
Rising edge (1 threshold):
the relay goes off when the measurement
exceeds
the threshold and stops when it
is
below
the threshold.
•
Falling edge (1 threshold):
the relay goes off when the measurement is
below
the threshold and stops when it
exceeds
the threshold.
•
Monitoring (2 thresholds):
the relay goes off when the measurement is outside the defined low and high
thresholds.
It is possible to set 2 different relays activation:
•
“F 400”
folder corresponds to the
relay 1
setting
•
“F 410”
folder corresponds to the
relay 2
setting
The relay setting procedure explained below corresponds to the relay 1 setting. For the relay 2 setting, go to the
corresponding folder and perform the same procedure as for the relay 1.
The transmitter is powered on.
