Relay wiring

[slychiu]

It is very difficult to check what you have done without a cclx file
The Output 3 may be On  but you may have some other event which causes it to turn on
we also cannot verify that you have programmed correctly
There is also the problem whether your connection of the relay to the light is correct

the Relay deactivated, but the Relay remained power on. When I reconnected the IN3 cable to OP3, the Relay activated again, light on and failed to switch off.

\"relay deactivated but relay remain power on \" does not make sense
we cannot advise properly, I suggest you get an electrician to help.

David, break it down into two parts: the comfort config, and relay wiring.

To check you have got the comfort output switching properly you can stick a meter between the output and 0v, or better still an led between 12v and the output with a resistor to current limit it.
e.g. https://www.laser.com/product_info.php/i...cts_id/930
That will prove you have the output switching on when you want it to.
If you are using Comfigurator you can actually watch the output status change, so you can see if it is on or off easily.


Wiring wise, The relay board you are using has configurable switch inputs using the jumpers. Have you got them set for triggering high or low ?
Will it accept an open collector \'input\', and does it have an integral pull-up resistor to pull the input high itself, or does it need an external one.

I would test it as follows:
This assumes using 3rd relay/channel being used.

Mains side: live feed to \'comm3\', output to light to \'NO3\' (normally open).

DC Side: DC+ to positive supply, DC- to negative supply.

With nothing connected to the input, turn the DC power on. Does the relay close or not ?
Ideally it shouldn\'t do.

Set the jumper to trigger low.
Connect a wire to \'IN3\' and connect it to DC-. This should turn the output on. If it has internal pull-ups when you disconnect the wire from DC- it should turn off. If you find this doesn\'t happen reliably it probably means the input is floating (no pull-up) and needs say a 10k ohm resistor between IN3 and DC+ to pull it high.

----
To connect to the comfort panel:
DC+ to positive supply (12v on comfort pcb), DC- to negative supply (comm next to it).
Comfort OP3 to the relay board IP3.

I hope that is of some help.

Hi John,

Thank you for your response.
My wiring circuit is exactly what you suggested. I also did the test you suggested i.e connect and disconnect IN3 with DC-, the Relay was activated and deactivated accordingly. It concluded that Relay is working perfectly.
Objective: Comfort turn on light ( connected to OP3) if the time is between 7 pm to 6am. The light will be turned off after 5 minutes if no further movement is detected. Similar to the example 1.4 of application manual. Refer the link above.

I had actually at the next stage of the problem. I have wired my PIR to zone 17 with zone type 24 with Response 45 On.

Response 45 action codes are as follow:-
73, 3, 69, 19, 70, 6, 193, 74, 5, 194, 1, 1, 44, 6, 255.
To test it, I changed my Comfort system time to 8pm. When I walked past the PIR, the PIR activated the relay and the light switched on. The problem is, the Relay and of course the light would not deactivated or switches off after 5 minutes.

I changed Response 45 5 minutes interval time to 5 seconds with Action Code 73, 3, 69, 19, 70, 6, 193, 74, 5, 194, 1, 0, 5, 6, 255. Similar result as above. It can only be turned off when I reset the Comfort system reset button. It appaeared that Response 6 to turn off Output 3 is not activated. When I measured the volatage across DC+ and IN3, the voltage remain 12V.

I am using Comfort 2 system whereas the example in 1.4 of Application.manual is for Comfort 1. Not sure they are compatible. I read in Action Codes manual page 60, couldn’t find any issue so far.

Would appreciate your help.

your Response 6 is supposed to turn off the output
You need to check what is response 6 action
Do you have Comfort 2 Optimum or Ultra?

[david8811]

Response 6 Action codes is default setting, which are 128, 3, 0, 255.

I just reconfirmed the action codes for Response 6 a while ago. My Comfort System Control Number obtained from Engineer Menu 743 is 743361. Not sure it is Ultra or Optimum

If you have programmed everything correctly then it should work
We are not able to check for you as you are not able to save the cclx file so you wil have to check all the responses yourself, with a good understanding of actions and responses
Check the action codes manual as a start
https://www.cytech.biz/action_codes_reference.html
make a control menu to turn on and off the output

For Comfort Ultra
194, 01, 00, 05, 107, 03 Start Timer 1, count = 5 seconds, and Do Response 875 (3 x 256 + 107)

Above statement is from Comfort Action Codes Manual, page 60. It says For Comfort Ultra, .....What is the last action code 03 means? There are 6 action codes here compared to mine is only 5 action codes. Could it be I missed something here as my Comfort is ultra I Guess.

[slychiu]

Action Code: 194
Parameter 1: Timer 1 to max
Parameter 2: timer count high byte - Seconds/256 (0 to 254)
66
Parameter 3: timer count low byte - remainder Seconds (0 to 254)
Parameter 4: Response 00 to 255
Parameter 5: Response High Byte for Comfort Ultra only.
The Timer value in seconds is entered in action codes 3 and 4 (16-bit value)
194, 01, 00, 05, 107, 03
Start Timer 1, count = 5 secondResponse = 3 x 256 + 107 = ???

Hi Chiu,

Q1 Can you explain to me the difference between timer 1, 2 or 3? Are these timers need to be preprogrammed?

Q2 From Action Codes Manual, Page 60. “Avoid 255 in the Response high byte and low byte as this will terminate the Response entry.”
What is that means?
