Hello,
I have bought 10 battleswitch with an SSC32U card connected using the TTL port on a RAPU unit from Brookshire.
All 10 battleswitch relays controls 220V motors for a robotic animation, each motor is 7.2w of power (very low consumption).
I can start the program without connecting the 220V of all motors and all is working good without any problem, but, if I start the program connecting the 220V for all motors, I have randomly some relays switching very rapidely and the RAPU card randomly crashes …
Have you any idea for my problem ? What can I do to let my system work ?
Thank you in advance for your answer
Hi,
The wiring of your setup is not very clear in the picture you posted.
]Do you have a common GND between you SSC-32U, your RAPU and your PSU ?/:m]
]How are you powering the SSC-32U (voltage and current) ? From the picture, it appears that you are powering the SSC-32U through the VL screw terminal, is this correct ?/:m]
]If so, try to power the Logic and Servo power inputs separably, by removing the VL=VS jumper, connecting a 5V power supply to VS1 and another 5V power supply to VL./:m]
]Could you provide a diagram/clear picture showing how you are connecting the 220V supply to the relays ?/:m]
Hello,
On this photo it was just a test after making the program on VSA Software.
Some of our motor have some broken capacitor and did not start or have multiple rapid cut on/off when relays are on. We plan to change them this week and make some new tests.
I will add a new power to SSC32 card and separate VL and VS1 powers (VS2 not used) and make some new tests. I will make new photos to show you the final mounting.
Thank you for your help.
Best regards
Hello,
Here are the full project in our laboratory : 17 self animated robots using 220V electric motors.
I thought that using SSC32U card with relays for each group of robots and a RAPU unit will be the solution.
I made the sequence on VSA and uploaded it to the RAPU unit.
If I don’t put 220V to motors all is working good, but when 220V is on, SS32U card make randomly a reset, all relays get off and on, making the RAPU unit crashing !!!
Then RAPU screen showing random chars, sometimes the program still continue, sometimes the sound cut off, sometime the sequence stops, I must reboot the RAPU unit.
Does these relays and setup can accept working with 220V ?
Thank you for your answer, this project must be installed in a public museum.
Best regards
P.S. : I decided to add new relays (using only 12V voltage) to command 220V motors after the relays connected on the SSC32U card. All is working now with this modification. All photos was taken before adding second relays. But I would like to have an answer for the “battleswitch” relays.
Each BattleSwitch Radio Controlled Relay - DE-01 should be able to switch up to 10Amps @ 28V DC amd 10 Amps @ 240V AC. Therefore, the battleswitches are most probably not the issue.
How are you powering VL and VS on the SSC-32U ?
Hello,
Thank you for your answer.
Yes I had made a lot of tests :
- VS and VL on same power supply
- VS and VL on separate power supply
- power supply on an inverter
- grounding common masses
Perhaps high electrical disturbances from 220V motors broke the communication between battleswitch relays and the SSC32U card, making both RAPU and SSC32U card to crash.
I use another couple of SSC32 card and RAPU for another animation (robot playing piano, all motors are using 12V power) and we do not have any problem with it (I will post some photo if you want).
Finaly the system works with another relays using 12V power controled by the battleswitch relays.
Unfortunately, we have dismantle all the animation to install it in our customer museum, no way for me to make new tests.
Best regard.
The Battleswitch is electrically isolated from the SSC-32 electronics. Therefore, theoretically, even if the 220V power line is noisy due to the motors BEMF, it shouldn’t affect the PWM signal or the 5V line of the SSC-32.
However, the SSC-32 could be affected if the 220V main line cables are too close to the low level signal wires.
