MALFUNCTION SIGNALLING
In addition to the most important data and messages (as shown in Figure 3), the information screens also include icons signalling system malfunctions:
·
External device malfunction (K14),
·
Internal controller malfunction (K15).
Each malfunction has its own flag in the malfunction code, enabling quick diagnosis of a potential problem - see tables 2 and 3.
Table 2.
Malfunction flags of external devices.
Malfunction flag
Description
Cause
0001.0000.0000

1. Incorrect type of external analogue sensor connected.
2. Malfunction of the external analogue sensor.
3. Internal controller malfunction.
0100.0000.0000
Break in the C+/C- input circuit.
1. No external analogue sensor connected.
2. Incorrect type of external analogue sensor connected.
3. Malfunction of the external analogue sensor.
4. Internal controller malfunction.

Malfunction flag
Description
Cause
0000.0000.0001
Internal power supply voltage outside the correct
range.
1. Internal controller malfunction.
0000.0000.0010
0000.0000.0100
24 V DC power supply voltage outside the correct
range.
1. Power supply voltage of the controller too low.
2. Power supply voltage of the controller too high.
3. Internal controller malfunction.
0000.0000.1000
No type of the controlled device was selected.
1. No type of the controlled device was selected in menu
Settings>Device type
2. Internal controller malfunction.
0000.0001.0000
No communication with the room temperature
sensor (fig.1 item.5).
1. Internal controller malfunction.
0000.0010.0000
Brak komunikacji z zegarem RTC.
1. Internal controller malfunction.
0000.0100.0000
No communication with the RTC clock.
1. The time of the RTC clock was not updated in menu
Settings>Time
2. Internal controller malfunction.
Table 4.
Causes of incorrect operation of the controlled device.
Symptom of malfunction
Cause
The controller remains switched off despite attempts to switch it on.
1. Incorrect controller connection.
2. Damaged S+ or S- cable.
3. Burnt fuse in the controlled device.
4. Controlled device malfunction.
5. Internal controller malfunction.
The controller signals a malfunction (0001.0000.0000), and the motor of
the controlled device does not rotate.
1. Mechanical lock of the controlled device.
2. Damaged R cable.
3. Controlled device malfunction.
4. Internal controller malfunction.
The controller signals a malfunction (0001.0000.0000), and the motor of
the controlled device is switched on for 30 seconds and off for another
60 seconds.
1. Damaged I cable.
2. Controlled device malfunction.
3. Internal controller malfunction.
Caution! Starting from the malfunction, the regulator measures a 30 seconds delay and afterwards switched the controlled device off for 60 se-
conds. After that time, another attempt at starting the controlled device is made. This cycle is repeated until the cause of the malfunction is solved.
MAINTENANCE
No maintenance required.
