3 Installation of the IG315/2
For the use of the device in a surrounding with higher
protection requirements, SWARCO TRAFFIC SYSTEMS
offers special enclosures (type GHIG300 / GHIG301).
Before switching on the power supply, the device must
be plugged onto the socket.
3.1 Special notes on the loop
The safe functioning of the device depends essentially on
the technically proper installation and laying of the loops,
since the loops are the sensors of the device. The loop
feed cable must be drilled approx. 20 – 50 times per meter
and must be laid in distance from life wires. For further in-
formation see notes on laying of loops (available at
www.swarco.com/sts).
4 Device adjustments
After every device adjustment
a new alignment must be effected
by pushing the reset-button (E).

4.3 Function selection switch (D)
Switch 1 on
Switch-off delay
on
The switching signal is switched-off with a delay
of 2 seconds after the loop is vacant (not in im-
pulse mode).
Switch 2 on
B-relay as
fault report
B-relay switches when detector fault. The func-
tion B-relay as impulse relay is invalid. The “im-
pulse output” or “impulse when leaving the
loop” can be emitted on the main relay (channel
switch (C) switch 4 on / function selection
switch (D) switch 3 on).
Switch 3 on
Impulse when
leaving the loop
active
The detector switches the B-relay only after the
loop is vacant. The channel adjusted to impulse
mode and the additional switch-off delay has no
influence on the “impulse when leaving the
loop”. In static mode the impulse is only emitted
after the A-relay is released.
Switch 4 on
Switch-on delay
on
The switching signal is emitted when the loop is
attenuated for more than one second.
Switch 5 on
Automatic
alignment
active when
fault
When there is a loop fault, the detector aligns
anew automatically after approx. 12 seconds. If
the fault lasts for a longer period of time, the de-
tector keeps trying to align until the fault is
eliminated. The relays and LEDs stay in “fault”
position until the alignment is effected.
Switch 6 on
Detection by
fault active
A loop fault is indicated on the LEDs and ad-
dionally the according channel relay is switched
on. For a combination with switch 6
on
, switch 5
must by all means rest on off
, since otherwise
the detector aligns anew after 12 seconds and a
vehicle which might stand on the loop will not be
detected anymore.

5 Alignment and fault diagnosis
5.1 Alignment
When switching on the power supply, when there are volt-
age interruptions or when the reset switch (E) is pushed,
the loop detector automatically aligns itself to the con-
nected loops and switches the relays to switching position
“loop not attenuated”. During the alignment period the
yellow power-LED (F) is blinking for a few seconds. With
a low sensitivity the detector is ready for operation at
once. After the alignment the power-LED (F) keeps glow-
ing.
Display of switching and failure status
The switching mode “loop occupied“ is indicated by a
glowing green channel-LED (A).
Loop failure caused by a short-circuit, an interruption or a
loop inductivity outside of the permitted range is indicated
by a glowing red channel-LED (B).
During the alignment phase there may be no
vehicle on the loop since it will not be detected.
