ERROR INDICATION ON THE ANALOGUE OUTPUT
The EE8915 features an error indication on the analogue output according to NAMUR recommendations (factory setting: disabled).
The feature can be enabled with the EE-PCS Product Configuration Software, see full user guide at www.epluse.com/EE8915.

flashing = Failure. Also indicated on the analogue output (NAMUR indication
enabled). The failure might be temporary, caused for instance by
overheating. If the flashing persists, contact E+E after sales service.
Important note:
» The manufacturer cannot be held responsible for personal injuries or damage to property as a result of incorrect
handling, installation, wiring, power supply and maintenance of the device.
» For failure-free operation and performance according to the specs, the GND supply and the GND analogue output
must be wired separately. Internally, the GNDs are connected to each other on the electronics board.

INSTALLATION
WALL MOUNT
Choose a location which minimizes the dust deposits on the filter.
DUCT MOUNT
The arrows on the enclosure indicate the flow direction. When correctly installed, a small
amount of air flows through the divided probe into the EE8915 enclosure, where the CO2
sensing cell is located, and back into the duct.
Very important
For accurate measurement and response time according to specification:
»Minimum air speed in the duct shall be 1 m/s (196 ft/m).
»The air flow shall be perpendicular to the opening holes on the head of probe.
