|2.3 Component side.|
|L2||FLiM learning mode (PB1)||1Hz||Yellow|
|L3||CPU is running||Continuous||Green|
|JP1||120 Ohm line termination¹|
¹) A CAN bus must be terminated on both ends to get 60 Ohm.
|J1, J2||'GCA' CBUS and 12V power||only needed if used in CAN-GC system|
|J3||'MERG' CBUS and 12V power||only needed if used in MERG Cbus system|
|F1..F4||External switch position feedback (2 inputs for each switch)|
|ICSP1||In-circuit serial programming|
|GCA137||Piggyback board connection for polarization|
Most servo's come with a connector which will fit on Servo 1..4 connector on the CAN-GC6.
The signal line (useally orange ) should be at the edge of the board.
| A nice mounting support is available from www.phgiling.net. |
Sideways or in line movement is possible
| The set contains all that is needed, incl. servomotor
see GCA servo support ServoSet
If you are not planning to use this option, F1..F4, U4 and U5 can be omitted.
F1..F4 are made for connection of limit switches, to feed-back that turnout is really on its desired position.
Switch should be on when position is OK
Connection should be made according this table :
|F1||1||straight||C + S|
|F1||1||round||C + R|
|F2||2||straight||C + S|
|F2||2||round||C + R|
|F3||3||straight||C + S|
|F3||3||round||C + R|
|F4||4||straight||C + S|
|F4||4||round||C + R|
IMPORTANT NOTE !!!!!!
Some users seem to know better, and solder wires directly to the pins or the pc-board.!
That is totally unacceptable !!
Wires will easily break off, and cause a lot of damage in many cases.
So use connectors !!!!!
In order to ease making these cables, it is also possible to buy the necessary tool, to create the PSK cables.
The best wire to be used with PSK connectors is 0,25 mm².
This special plier will be sold for net price of € 18,25 if ordered together with complete kits.
Just ask peter.
The switch interface option Single Gate must be set.
