mxion ZKW 2 Channel Switch Decoder

ZKW 2 Channel Switch Decoder

Introduction

Dear customer, we strongly recommend that you read these manuals and the warning notes thouroughly before installing and operating your device. The device is not a toy (15+).
NOTE: Make sure that the outputs are set to appropriate value before hooking up any other device. We can’t be responsible For any damage if this is disregarded.
NOTE: The switch address is from CV120/121! For addresses < 256 you need only write to CV121 etc.

General information

We recommend studying this manual thoroughly before installing and operating your new device. Place the decoder in a protected location. The unit must not be exposed to moisture.
NOTE: Some funktions are only available with the latest firmware. Please make sure that your device is programmed with the latest firmware..

Hook-Up

Install your device in compliance with the connecting diagrams in this manual. The device is protected against shorts and excessive loads. However, in case of a connection error e.g. a short this safety feature can’t work and the device will be destroyed subsequently. Make sure that there is no short circuit caused by the mounting screws or metal.
NOTE: Please note the CV basic settings in the delivery state.

Connectors

Switch lamps between A1/A2 and common + pole. Use with 3-wire switches the common DEC+ pole as the center line. Not use 3 pole LGB drives!

Product description

The mXion ZKW is a 2 channel switch decoder with 2 function outputs for switch laterns or signal lighting. The two points are also independently of one another and freely adressable. For this purpose, dimming and time units. Here are the special features as with the mXion MFB that one integrated 3-way switch is implemented. This controls 3-way switches so that always has a defined direction of the soft takes place and derailments can be eliminated. Fit the switch to ,,straight” if using this mode or use CV 49 Bit 3/4 = 1. CV 49 Bit 3/4 = 1. The rear tongue atomatically switches on ,,straight” when the front is operated. man die Switches one the front tongue back again, so also takes the rear tongue again the old direction. If the front tongue is on ,,branch” man and the rear tongue is now switched and the anterior tongue in the appropriate direction, so that on the one hand there are no derailments of vehicles and on the die other hand the operation of the 3-way switch is simplified. So you can use the address for the switch the front tab ,,branch right” and with the address for the rear tongue ,,straight” or ,,branch left”. The other tongue extra will automatically so that does not must happen.
Another highlight of the ZWK is the setting for decoupling tracks. Here you can create a corresponding function output (A1 to SW1 and A2 to SW2 bound in this mode) CV 49 Bit 0/1 and automatically with of the switch. The advantage ist hat the luminous “E” of the LGB® decoupling track as the decoupler is active. Now, wheather the decoupler is still disengaged or coupling.
Ideally, the two modes, complement each other with the mode for defined position of SW1/2. The outputs of the switches switch automatically to ,,stop” or ,,branch”. This hast he advantage that signals on red, decoupling tracks to normal and turn switches to ,,branch” after the system has been switched on.
So you always have a defined starting position.

Programming lock

To prevent accidental programming to prevent CV 15/16 one programming lock. Only if CV 15 = CV 16 is a programming possible. Changing CV 16 changes automatically also CV 15. With CV 7 = 16 can the programming lock reset.
STANDARD VALUE CV 15/16 = 250

Programming options

In POM (programming on maintrack) the programming lock is also supported. The decoder can also be on the main track programmed without the other decoder to be influenced. Thus, when programming the decoder can not be removed.
HINWEIS: Um POM zu nutzen ohne andere Decoder zu beeinflussen muss Ihre Digitalzentrale POM an spezifische Decoderadresse unterstützten.
NOTE: To use POM without others decoder must affect your digital center POM to specific decoder adresses.

Programming binary values

Some CV’s (e.g. 29) consist of so-called binary values. The means that several settings in a value. Each function has a bit position and a value. For programming such a CV must have all the significances can be added. A disabled function has always the value 0.
EXAMPLE: You want 28 drive steps and long loco address. To do this, you must set the value in CV 29 2 + 32 = 34 programmed.

Programming switch adress

Switch addresses consist of 2 values. For addresses < 256 the value can be directly in address low. The high address is 0. If the address is > 255 this is as follows (for example address 2000):
2000 / 256 = 7,81, address high is 7 2000 (7 x 256) = 208, address low is then 208.
Programm these values into the CVs of SW1, SW2, A1 and A2.

Reset functions

The decoder can be reset via CV 7. Various areas can be used for this purpose. Write with the following values:
11 (basic functions)
16 (programming lock CV 15/16)
33 (function and switch outputs)
