Important
HELIO gas detectors are fully tested and pre-configured before leaving our
manufacturing facility. If you intend altering the configuration we recommend
contacting your local supplier to discuss any changes in advance. Only qualified
and competent personnel approved by Helio Gas Detection may install,
commission and maintain Helio Gas Detection products.
If this product is used in countries outside of the European Union, the
standards and regulations valid in these countries must be observed.
Warranty
All Helio Gas Detection products carry a 12 month warranty. Damage caused to
products by improper transportation, handling and / or installation are not
subject to warranty.
HELIO Gas Detection cannot be held responsible for damage caused by non-
compliance.
Intended Use
HELIO Gas Detection Systems are intended to be used for fixed continuous
monitoring for mixtures of flammable, explosive or toxic gases and vapours
with air under atmospheric conditions.
HELIO gas detectors are standalone devices but can be connected to a suitable
control panel.

Internal wiring
Use ferrules if using stranded cables. PCB terminal blocks up to 1.0/1.5mm2.
Use twisted pair cable with overall screen when connecting RS485 network.
Start up
When initially powered on, the gas detector should be allowed to warm up
allowing the sensor to stabilise before calibration.

HGD G4CH VER. 1.1 7
Maintenance
Helio Gas Detection systems must be inspected and serviced regularly by
trained service personnel. We recommend that a service contract be obtained
with a HELIO Gas Detection approved vendor and that all repairs also be
carried out by them. Only authentic HELIO components may be used for
maintenance purposes. During regular service inspections a full zero and span
calibration must be carried out. Verify the activation and de-activation of all
alarm output signals.
Ensure that gas can freely penetrate the sensor. If required replace the sensor.
Use sensors which are approved only by HELIO Gas Detection.
Sensor Replacement
Observe national regulations for the installation of electrical apparatus in
potentially explosive atmospheres devices (EN 60 079-14). Isolate signal
outputs and de-energise the gas detector.
Unscrew stainless steel sensor housing and remove existing sensor. Align the
replacement sensor pins with the PCB mounting inserts and plug in the new
sensor. Ensure new sensor is the same gas type and model as the original
sensor. Energise the transmitter and observe sensor warm-up time allowing
sufficient time to stabilise.
When sensor stabilisation is obtained, verify the zero and span calibration.
____________________________________________________
Attention:
After installing a new sensor the gas detector must be calibrated.
