3. Setting
Setting of EX-13 for desired function is performed us-
ing straps and potentiometers (under the lid of the
encapsulation) as follows:
1. The input function is selected by means of a
strap. When EX-13 is to be used for lighting control in
one room one selects “single area”, or in two sepa-
rate rooms one selects “two areas” and two pres-
ence detectors.
In the “single area” position one main detector must
be connected to detector input 1. In the event of de-
tection using this detector, the lighting is switched on.
If a detector (IR or acoustic detector) is also con-
nected to detector input 2, it does not switch on the
lighting in the event of detection, but lighting which is
already on is kept switched on for as long as detec-
tion takes place.
In the “single area” position the “function” input is
also affected by the position of the strap. A burglary
alarm or fire alarm (closing output)can be connected
to the function input. In the event of an alarm, all
lighting is then switched on and the ventilation is
switched off (output 5). See also “3. Setting”, item 3.
In the “two areas” position, two separate rooms can
be controlled individually by two detectors.
If an EX-13 is used in a sports hall with a folding par-
tition, a breaking magnetic contact can be connected
to the “function” input and can detect whether the
partition is open or closed. If the partition is open
(magnetic contact closed) the lighting is switched on
in both rooms even if only one detector detects pres-
ence.
Without a strap, EX-13 can be used for control of
the lighting and the ventilation in divided rooms
where a magnetic contact detects a folding partition’s
position. If the strap is absent the lighting can be
switched off and on individually (in accordance with
the outputs’ programming) in the halves of the room
even when the partition is open. If the partition is
closed the control functions separately for each half
of the room.
2. Relay outputs 1-4 are controlled individually using
four straps. Each output can be programmed in three
ways as follows:
A = Automatic start; the lighting is switched on
automatically in the event of detection.
SB = Blocking (Start Block); the lighting is blocked
by the blocking input, e.g. a photocell with clo-
sing contact function. If the input is not blocked
the lighting is switched on automatically upon
entry into the room.
M = Manual, the lighting is never switched on auto-
matically. Switch-on occurs with connected in-
stantaneously closing contact.
Without a strap there is a fourth function, “buy time”,
with the following function: The lighting is switched
on manually and stays on until presence is detected.
When detection ceases the lighting is switched off af-
ter the delay which is set in the detector.
With outputs 1-4, the lighting can be switched on and
off manually using instantaneously closing contacts
connected to each input.
3. Relay output 5 (Delay out)
Output 5 is for ventilation or lighting control and has
two time functions which are set using two potentiom-
eters.
Setting is performed by the relevant potentiometer
being set to the requisite delay. “On” is turn-on delay
and “Off” is turn-off delay.
The ventilation can also be started manually with an
instantaneously closing contact connected to the “De-
tect delay” input (fan).
NB: The ventilation cannot be switched off
manually.
Switch-off delay for the ventilation:
To avoid start-up of the ventilation taking place in the
event of brief presence in the room there is a delay
time which can be set to between 0 and 60 minutes.
The output is not activated until the presence detec-
tor has detected constant presence for the entire de-
lay period.
Turn-on delay for lighting:
When an alarm is connected or when the “Delay Out”
output is used for control of the lighting (e.g. in appli-
cations with LS-2), the “ON” potentiometer must be
set to zero.
Turn-off delay:
To guarantee outward ventilation of the room after a
prolonged presence, a turn-off delay of between 0
and 2 hours can be set.
4. Photocell
If a photocell (order no. 13100) is connected to the
“Block” input to block switch-on in the event of day-
light, the sensitivity can be set using the “Photocell
Sens” potentiometer. For increased sensitivity the po-
tentiometer should be turned clockwise. Increased
sensitivity means that less powerful light is needed
for blocking to occur.
