All Murco units are fully tested prior to shipment and so any difficulty, which arises, may be due to transport, installation problems or site difficulties i.e. high temperature, high humidity, and / or other gases present.

It is very rare for a unit to fail and so most problems can be solved on site and this saves the operator removing the unit and returning it to us.  We are happy to provide support to customers. Please contact us and let us help you.

We need to establish the nature of the problem so that we can help.  It is possible to misinterpret what is happening. Referring to the manual for the particular product and answering the questions of the type below can often solve the problem.

What is happening?

Is it a fault?

Is it a false alarm?

Is there power to the system?

1- Fault

This can be due to a number of occurrences.

• Wires connected incorrectly.
• Physical damage to the sensor.
• Faulty wiring, or cable too long or wrong specification.

2- False alarms
(but again: are you really sure you do not have a leak?).

This can be due to

• Background interfering gases
• Incorrect locations or using the wrong sensor version or enclosure
• Adverse temperature conditions
• Adverse humidity conditions
• Calibration potentiometers may have been inadvertently adjusted or annual calibration may be due

If the calibration set pots have been moved or adjusted they can be reset, contact us for instructions.

3- No power to the system?

Then check supply, fuses on the supply and the power fuses in the controller, etc.

Installation manuals have short trouble shooting sections.

Contact Murco for detailed instructions and support.   We will be pleased to hear from you.
