Faultfinding guide

In this section a simple fault-finding guide is given. This is intended to be used to remedy the
consequences of incorrect installation. If more serious faults or problems arise the installer
should contact a qualified technician.

Problem

Actions

Transmitter display does not light up: –

Check that the mains supply to the transmitter
is connected and that the transmitter is
switched on.

Transmitter indicates “no radiators”: –

Ensure that connections to all radiators have
been made correctly and that each radiator’s
mains supply is connected and switched on.

Transmitter indicates “radiator fault”: –

Ensure that connections to all radiators have
been made correctly and that each radiator’s
mains supply is connected and switched on.

–

Examine the radiator LEDs.

Transmitter indicates “no network”:

–

Check that the optical network is connected
correctly.

–

Check that the control unit of the DCN Next
Generation conference system is switched on or
disable the network mode (menu 4B).

Transmitter indicates “network
error”:

–

Enable the network mode (menu 4B) or
disconnect the transmitter from the optical
network.

Transmitter does not synchronize
automatically to the maximum
number of channels in DCN:

–

Ensure that the number of channels is set to
automatic (using menu item 4B).

Emergency contact on the
transmitter does not work:

–

Check that the emergency contact is connected
correctly.

–

Check that the audio is connected according to
the selected auxiliary input mode (menu 4I).

–

Check, when the network mode of the
transmitter is enabled, that the transmitter can
connect to the optical network.

Red LED flashes and amber LED is on
of one or both IRED panels of a
radiator:

–

IRED panel is in temperature protection mode.
Check that the natural airflow around that
radiator is not obstructed. If not so, replace the
radiator.

Both red LED and amber LED are on
of one or both IRED panels of a
radiator:

–

IRED panel malfunctions and the radiator
should be replaced.
