Problem with teachin for TCM320C in Mode 3

Question

Hello,

I am trying to set the Mode 3 (4 relay channel mode) of the TCM320C by setting the ADIO0 pin at 0.82V (25% 3.3V approx).

I followed the sequence:

1. Press CLR button(> 0.5s) on EOP350 board to clear the Previous configuration

2. Press the Rocker on the PTM200C

3. Press LRN button(>0.5s) to finish the learning for CH0

4. Press LRN button(>0.5s) to start the learning for CH1

However this is not blinking.

I have made the shorts on the board connected SJ8, SJ9 and SJ10.

Kindly out line the clear procedure to have this mode working.

Warm Regards,

Abhijit

Hi,

I finally got the Learning right for Mode 3.

First let me explain Mode 3 of TCM 320C.

In this mode the TCM 320C is capable of learning up 30 rockers per channel. We have 4 Channels in this mode.

Now in order to enter this mode we need a voltage divider of 25% of VDD. Actually as per the EnOcean User Manual for TCM 320C if one supplies voltage to the mode pin in range of 20% to 27.99% of VDD.

So I chose 25% of VDD to do this.

Now to get 25% of VDD(3.3V) we need a voltage divider.

In my case I used a 10k and 3.3k resistance divider network between VDD and Ground. Vref = 3.3k x 3.3 / (3.3k + 10k) = 0.818V which is around 24.8% of the VDD.

This helps to enter the Mode 3. Remember that here on the TCM 320C module the ADIO0 pin serves as the Mode Pin.

Next how to initiate the Learn Process. I used the EOP350 to do this.

1. Press Reset (>0.5s)

2. Press Clear (>0.5s) to clear the previous settings and then enter the Learn Mode

3. Channel 0 LED blinks. Press the Rocker 1 switch - LED should stop blinking

4. Press the Learn Switch (>0.5s) to change to Channel 1

5. Channel 1 LED blinks. Press the Rocker 2 switch - LED stops blinking

6. Press the Learn Switch (>0.5s) to change to Channel 2

7. Channel 2 LED blinks. Press the Rocker 3 switch - LED stops blinking

8. Press the Learn Switch (>0.5s) to change to Channel 3

9. Channel 3 LED blinks. Press the Rocker 4 switch - LED stops blinking

10. Press the Learn Switch (>0.5s) to Finish the Learning Process - All LED switch off

Important thing to note is while pressing the Learn Button, make sure that the LED is stopped blinking else that channel would remain un-programed.

This solved my actuator learning issue. Now at least the rockers can control some thing.

However the other question still remains that how we can do this via the TCM 310 as we do not know the ID for the TCM 320C module.

Hi Abhijit,

if you want to control your actuator (TCM 320C) via self-powered switch (PTM 200C) and
a smart home server (Raspberry + EnOcean PI TCM 310) you have to options:

1. Learn switch ID to the ID table of the actuator (you have done this already) and
learn TCM 310 ID (e.g. base ID) to the actuator. So you can control the actuator
from the switch and from the server. If the server is done the switch still works.

2. Learn switch ID to smart home server and learn smart home server to actuator.
Now you have full control via smart home server, but if it is down nothing can
control the actuator.

You will find more details about the learning concept and base ID within
the EnOcean knowledge base e.g. EnOcean - What is difference between Base ID and Chip ID?
