PEL 1000 / PEL 1000-M

- The transmitter should be installed above the measuring point to avoid condensation problems.

- The duct overpressure is detected by connecting the measuring point to + connector and by leaving the

- connection open (surrounding space pressure). Accordingly, the duct under-pressure is detected by
connecting the measuring point to - connector and by leaving the + connection open.

- Install the measuring hoses carefully so that the hoses don't bend too tightly. Too tight curves may prevent the
air flow to the sensor.

Wiring

- The hose length doesn't effect on the measuring accuracy. However, long hoses generate delay on the
measurement.

- Mount the device cable entry downwards, so that moisture and water gets out of the housing freely.

Device wiring and commissioning can only be carried out by qualified professionals. Always make the
wirings while the power is switched off.

ZERO POINT CALIBRATION

The zero point drift can be eliminated by performing the zero point calibration. It is recommended to calibrate the zero
point every 6 months. At the commissioning the zero point calibration should be done after one hour of powering the
transmitter.

1. Unplug the plastic tubes from the inlets.

2. Press the zeroing button until the indicator light lights up (without flashing).
