Adapting the LGB 55070 Feedback Module for connection to a Massoth Feedback Module 817000 for automatic Drive and Switch Routines.
The 55070 Feedback Module receives signals (‘feedback’) from external contacts, like the LGB track contacts 17100, Massoth Digital Track Contacts 8420502, or Massoth Digital Track Contacts 8420602.
Home Brew, DIY external track contacts can be constructed from minimal components, refer to another Blog Posting, for use with the Feedback Modules for Automatic Drive and Switch routines.
When using the LGB 17100 Track Contacts , connect both terminals marked with triangles to each other.
Adapted LGB track contacts 17100.
The 55070 Feedback Module sends signals via the Bus cable to a Massoth Feedback Module 817000, and from there to either a PIKO 35010 Central Station or a Massoth 1210Z Central Station.
Programming and configuring the Feedback Module’s for operational use.
The device ID is pre-set at the factory to ID 2, (ID only valid for LGB Systems) this can be left at it's default value, the Massoth Feedback Module has no requirement for this information.
On the feedback interface, there is a twelve-pole connector with four groups (A – D) of three terminals each (a, ground, b).
Connect the black terminal in the center of the group with one pole of the contact.
Connect the white terminal, a or b, with the second pole of the contact.
You can connect two separate contacts to the terminals a and b.
All black ‘ground’ terminals of the feedback interfaces are connected.You can connect several contacts to each terminal on the LGB 55070. They must be wired in parallel.
On the other side of the feedback interface, there are three phone-style sockets,‘LGB-BUS’ and two sockets on the right marked ‘Slave’.
To avoid unintentional connections to the DiMax Bus, place a cover over the LGB BUS socket.
Use either of the two sockets marked Slave, connect a cable to either of the Slave sockets on the Massoth Feedback Module 817000.
This is a two stage process, first set up and configure the Massoth Feedback Module 817000 to act as the Master Module then set up LGB 55070 Feedback Module as a Slave Module.
For details, instructions and configuring are contained in the following manual,
From default settings as supplied, only CV 3 requires changing to a value of 5.
To program the LGB 55070 Feedback Module.
Using the DIP switches to assign address blocks to LGB 55070 Feedback Module.
Remove any cables from the Slave sockets.
Remove the screws on the bottom of the Feedback Module. Open the housing.
Set the DIP switches according to the table below.
As this is now designated a Slave Module, the Massoth Feedback Module 817000 is the Master Module at assigned address 1 – 4, the first available address range will be 5 – 8.
Set DIP switches 8 + 6 + 1 to ON.
Re connect the cable to the Slave socket and connect to a Slave socket on the Massoth DiMAX Feedback Module 817000, which should be connected to a track power source.
Red LED on the circuit board flashes rapidly (programming successful).
Remove the cable from the socket once again.
Set all DIP switches to OFF.
Reassemble the LGB 55070 Feedback Module.
Reconnect the cable from the Slave socket to the Massoth Feedback Module 817000.
Ready to operate.
Test setup to verify correct operation, of the two Reed Switches, both Feedback Modules and the Automatic Drive routine.
Total of 16 Contact Address can be used at any one time, within a Automatic Drive or Switch Routine, consisting of 32 elements made up of 16a contacts and 16b contacts.
Address blocks are in 4's, for simplicity use as 1 -4, 5 - 8, 9 - 12, and 13 - 16.
One minor detail from using the PIKO DCC 35010 Central Station, that it is not able to report the Feedback information on the lower part of the PIKO Navigator screen, as the Feedback details are Massoth DiMAX specific.
