8. SETTING THE RESPONSE TIME
A trimmer is available on the receiver for setting the photocell response time.
Set the response time, as described in the figures below, according to the type of installation and the level of
protection required.
9. FREQUENCY SELECTION
To prevent interference if installing more than one photocell, it
is possible to set a different work frequency for each photocell,
by choosing between 4 available values.
Set the frequency using the two dip switches on the receiver
and on the transmitter (see “Frequency selection” in section 1).
Select the same frequency on both the receiver and the
transmitter.
