Test the periphery using room unit QAX34.3
This function requires a QAX34.3 with index D or higher!
The HandyTool allows you to test the connected field devices (sensors, actuators).
This works only for the controller with the connected HandyTool; it does not work in
master/slave mode.
An application must be
selected
and
fully parameterized
in the controller
(address and zones can contain default values).
Start parameterization mode:
•
Press buttons < , > and – simultaneously for about 2 s until the display turns dark.
•
Release the buttons.
•
Press button – twice briefly.
•
Press b and – simultaneously for approx. 2s
Æ
The display goes dark.
•
Press twice briefly.
The display now shows 0 (mode 0).
Use + and / or – to choose between the following modes:
•
0 =
Normal mode (normal room unit functions).
•
1 =
Test mode
•
2 =
Display mode (see 2.5.2).
•
3 =
Parameterization mode (see 2.5.2
•
4 =
Upload (see 2.6).
•
5 =
Download (see 2.6).
•
6 =
Service mode.
The following positions can be selected depending on the type of parameterization.
They are displayed with prefix "T".
The list shows all theoretically possible positions. However, only positions that are
available for selection based on the type of parameterization are displayed.
Theoretically possible positions for periphery testing:
T 01
Sensor input B1
9)
Value of B1 in °C.
T 11
Digital input D1
9)
True state of the contact at D1 (0 = open; 1 = closed).
T 12
Digital input D2
9)
True state of the contact at D2 (0 = open; 1 = closed).
T 21
Heating valve
1)
2)
7)
8)
By considering the configuration (proportional; 100 = 100% pos. signal).
(Also applies to damper in FNC20).
T 22
Cooling valve
1)
2)
7)
8)
By considering the configuration (proportional; 100 = 100% pos. signal).
(Also applies to damper in FNC20).
T 23
El. Heating register
3)
7)
Pulse to the electric register (value > 0
Æ
10 s pulse).
T 25
Heating surface
1)
4) 7)
By considering the configuration (proportional; 100 = 100% pos. signal).
T 27
Damper
1)
4)
7)
By considering the configuration (proportional; 100 = 100% pos. signal).
T 31
Fan relay
6)
Speed control (%-value converted to speeds).
T 41
Relay Q14
6)
(0 = Relay deenergized; 1 = energized).
T 42
Relay Q24
6)
(0 = Relay deenergized; 1 = energized).
T 43
Relay Q34
6)
(0 = Relay deenergized; 1 = energized).
