Functional Description:
TRANSTEC's Switching Module serves the noisefree regulation of brightness of low-voltage halogenlightings, which are powered through transformers. For immaculate functioning the module needs to be operated through a TRANSTEC WV-Transformer with winding extension (T1) in the primary-circuit.
The switching effects the lighting system, depending on the modul and transformer, two or three defined light levels:
100% light intensity
50% light intensity
25% light intensity
The switching has to occur within one or two seconds.

Memory-Function:
Remains the module switched off for longer than two seconds, the first level (100% light intensity) will be automatically switched on. Because of this a derivated action is being realized.

Short-Circuit Cutoff:
In case of a short-circuit in the secondary circuit a secure shut-off at every level of the module is initiated. A red light-diode signals the shut-off. Now the module has to be switched off through the light switch and can be used again after fixing the actual reason for the short-circuit (reset through light switch).

Safeguarding:
To protect the lighting system from any flaws in the primary circuit of the transformer, we recommend the use of a glass tube fuse aligned for the application with the power required by the lighting system (F1). For this kindly refer to the following nominal values, which should not be exceeded:
for 200VA >> T 2,0A (max. TT 2,0A)
for 250VA >> T 2,5A (max. TT 2,5A)
for 300VA >> T 2,5A (max. TT 2,5A)

Switching:
Switching occurs through defined on-off switching within a time frame of 1-2 seconds. If this time falls short of a second no actual switch-over will be achieved, which means the already active switching mode remains in effect. If 2 seconds are exceeded, a switch over into the Memory Level is being caused. This refers to the connection denoted „yellow" and means that, as mentioned above, the module switches back into the first level (100% light intensity).
Softstart:
Each time the system is switched on, it will basically happen through a softstart caused by the switching module, which requires the correct connection of TRANSTEC`s WV-Transformer with the module. Because of this, it is imperative to connect the module exactly as it is showing on the label above the clamps.

Parallel Alternatively Synchronous Working:
In case two or more systems are powered by the same power supply system and are in use at the same time, synchronous working is guaranteed. Flickering of the light can occur at the moment the switching is carried out ; however, it does not represent a flaw of the systems! If there are two or more systems powered by the same power supply system and are individually connected, a temporary flickering of the light in the other systems can also not be ruled out during the process of switching over. But also in this case it does not mean that there are any flaws in the system.

Installation of On/Off Switch with Control Lamps:
Problems may occur, if the control lamps are lying parallel to the On/Off Switch, so that no derivated action through turning the switch can come about. In such cases the switch needs to be supplied through a separate N-conductor or one needs to abstain from using the Control Lamp.


While operating two or more systems through the same power supply mutual interferences may occur. These interferences can take effect while switching on or over is being conducted at one running system. This manifests itself through temporary flickering or stand-alone switching over into the next level of the other system. In such a case the impacted system has to be switched back manually into to its former level.
If other inductive consumer loads are connected to the same power supply during operation of one or more systems, a short flickering of light can occur at the moment of hook up. This does not represent a misdemeanor of the system.
