Fault messages

When the system detects a failure for the first time, a flashing fault message pops-up on any menu screen:

The fault status of the radiators can be seen in the second screen of the transmitter main menu:

Menu Item Value (read only) Description

1 Fault Status Fault:

- No Faults

- Radiator Fault

The connected radiators function without problems.

One of the connected radiators is not functioning properly.

No radiators are connected to the transmitter - No Radiators

- No Network

When the Network Mode (see section Set

network mode (4B), page 52) is Enabled, this

fault is shown when there is a fault in the optical network.

- Network Error

When the Network Mode (see section Set

network mode (4B), page 52) is Standalone,

this fault is shown when there is a fault in the optical network. This message usually occurs

when the Network Mode (see section Set

network mode (4B), page 52) is Standalone,

and a DCN Next Generation CCU is connected to the transmitter.

Push the menu button to remove the fault message from the screen and to go back to the menu screen that was visible before the fault message popped-up. The flashing message will also disappear when the fault has been resolved. See next section how to resolve this problem.

Faultfinding guide

Troubleshooting | en

73

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”:

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

Emergency contact on the transmitter does not work:

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

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

– 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.

Problem

Infrared receiver fails to function properly:

The charging indicator LED on the receiver is blinking:

Receiver discharges very quickly:

Bad coverage:

Actions

– If disposable batteries are used, check whether the batteries have sufficient capacity and whether they are inserted with the correct polarity.

– If a battery pack is used, ensure that the battery pack is fully charged.

– Ensure that the headphone is connected properly.

– Switch the receiver on and check whether the display indicates a channel.

– Ensure that the receiver picks up sufficient IR signal and check whether the antenna symbol becomes visible.

– Enable the mini radiator (menu 4M) and check the receiver by holding it in front of the mini radiator of the transmitter.

– Ensure that the volume control is turned up.

– Set the transmitter in test mode and check whether the test tone is audible on the receiver.

– If the test tone is not audible, do the same test with other receivers. If all receivers do not work properly at that spot, check the coverage of the

system (see Test the coverage area, page 67).

– Check that the charging unit is used under the specified working conditions (see technical data).

– Check that the receiver contains a battery pack which is connected correctly.

– Ensure that the receiver is at room temperature and re-insert the receiver in the charging unit.

– If the charging indicator starts blinking again, replace the battery pack and check whether the problem is resolved.

– Replace the battery pack and check whether the problem is resolved.

–

Do the tests as described in Test the coverage

area, page 67.
