Introduction
Thank you for choosing an Intelligas product. Please follow these instructions to ensure a safe, functional and
long-lasting installation.
This information is important and should be read and understood before attempting installation.
If you are unsure of the terminations and their design voltages or function then refer to this guide or our technical
support line, you can call 02381 290444 or you can text 07952269791 and we’ll get back to you as soon as we’re
available.
Siting the panel
Choose a suitable mounting position for the control unit. Mount the unit away from sources of extreme heat. Ensure the panel is
placed in a position where mechanical damage is unlikely and where it can be easily accessed for use and maintenance.
Fix the panel using the marked enclosure holes only. Take care not to damage the internal wiring or PCB of the unit when drilling.
Under no circumstances should wiring be routed behind the PCB of the control panel.
Control panel supply
All our control panels (except the KVM-SF) should be supplied via a fused spur connection unit. The fuse should be changed to one
that’s rated at 5amps.
KVM-SF ONLY if the panel is supplying the fans directly from the PCB then it should be supplied via a 16amp single phase isolator.
If the panel is controlling Inverters and only the output signals are being used then, as above, the panel should be supplied by a 5amp
fused spur.

Field wiring
All wiring from the supply and to the gas valve carries mains voltage (230v ac nominal). The current edition of the IEE Wiring
Regulations should be strictly adhered to, wiring and connections should be made by a suitably qualified electrician or competent
person.
The field wiring voltage to the interlock inputs is reduced to 24 volts, do not connect mains to the air pressure switch terminals,
e-stop, analogue input/output 0-10v control, gas detector or fire alarm terminals.
Please follow the first fix wiring schedule set out below:
1) Main supply 2 core + E 1.5mm (as per regulatory requirements)
2) Gas valve 2 core + E 1.5mm (as per regulatory requirements)
3) Pressure switches 2 core + E 1.5mm (YY type cable)
4) Fire alarm interlock (if req) 2 core + E 1.5mm (FP type cable)
5) Emergency stops 2 core + E 1.5mm (YY type cable)
6) Gas detection equipment, If fitted, 3 core screened (CY type cable)
7) Gas pressure switch, if fitted, 2 core + E 1.0mm (YY type cable)
8) 0-10v signal wiring, if fitted, 2 core 1.0mm (CY type cable)
Where multiple supplies enter a control panel, perhaps in a current sensing interlock. It is preferable that each supply is on the
same phase. If this can’t be achieved, then additional warning labels should fixed in a suitable location on the control panel.
The advice given on these instruction pages, specifically to cable types and ratings may change depending on cable lengths and
installation conditions. If you are not sure about any of the cable types or ratings then contact our technical support team.

100 Series Gas Ventilation Interlock System

Interrupt the phase
conductor from the spur
to the fan speed
controller and divert the
supply through the
on-board current sensor.
Do not divert supplies
out of any speed
controller, it won’t
work!
Supply to the gas valve.
Ensure there is a local point
of isolation for the gas valve.
Mains supply in to the unit
(230v).
This supply should be
derived from a fused spur
fitted with a 3amp fuse.
Connect the CO2 detector into these terminal as set out below:
24V - AC/DC + | 0v - AC/DC - | in - Vco2
Commission the CO2 detector using the pot marked CO2. If the
pot is turned fully anti clockwise, the CO2 function of the panel
will be disabled, however, when a co2 detector is connected the
alarm level should be set on this pot setting the pot at 12 o’clock
will be an alarm point of 2500ppm. 9 o’clock is 400oppm and so
on. Pre alarm is set to 60% of the alarm setting.
Set the fan current
levels using the pots
on the PCB for each
fan. Run the fan at
minimum speed to
set the low limit and
at full speed to set
the high limit. Once
the setting is in range
then the green LED
will illuminate
NB: If only one fan is
being used then the
other current sensor
must be disabled by
turning the unused
current sensor to
“on” or “disable”
using the dip switch
on the PCB.
These terminals can be used to connect extra
current sensors or pressure switches to indicate fan
faults on the front of the panel. Estops and Fire
signals can also be connected here. Link if not in
use.
Option switches - switch 1 turns on / off gas proving function of the
panel, link the terminal marked “gas proving switch or switch a”
regardless of whether gas proving is in use. Switch 2 extends the gas
proving time from 30 seconds to 60 seconds. Gas pressure switch is
required for the gas proving function.

To comply with gas regulations manual
isolation points, purge points and test
nipples may be required. This drawing is
for information only and the necessity of
the above items should be checked to
ensure compliance with the current
regulations.
