Universal Node or 32-8 node
Switches & led’s
- First a yellow led : SERVICE-led. Lights up when you push the service-switch. When this led flashes or is lit continuously, a severe software problem occured in the node. ( call us )
- Second a red led : RECEIVE-led
- Third a red led : TRANSMIT-led
- Bottom a green led : lights up when power supply is ok.
At the connector-side you’ll find :
- A push-button switch : SERVICE-switch. This transmits the ID-number of the node.
- A resettable thermal fuse : when this pops out, a little white flag is visible. After removing the problem, such as short circuit, push it back in to reset.
Connection :
There are two identical 6-way connectors at the right of the node. The left one may be used for connecting nodes who need 12V power supply, max 800mA such as reader or weight controllers . MAXIMUM 3 NODES TO SUPPLY. The right one is to connect the major network.
| pin 1 | +12V (output) | ||
| pin 2 | GND | ||
| pin 3 | NC | ||
| pin 4 | Network A | ||
| pin 5 | Earth ( shielding ) | ||
| pin 6 | Network B |
The 12-way connector used for the outputs. The output voltage is 24 Vac.
| pin 1 | output 1 | ||
| pin 2 | output 2 | ||
| pin 3 | output 3 | ||
| pin 4 | output 4 | ||
| pin 5 | output 5 | ||
| pin 6 | output 6 | ||
| pin 7 | output 7 | ||
| pin 8 | output 8 | ||
| pin 9 | Common | ||
| pin 10 | Common | ||
| pin 11 | NC | ||
| pin 12 | NC |
The 36-way connector ( nearest to the mounting flange ) used for the inputs.
| pin 1, 10, 19, 28 | input 1 : dose 1, dose 2, dose 3, dose 4 | ||
| pin 2, 11, 20, 29 | input 2 : dose 1, dose 2, dose 3, dose 4 | ||
| pin 3, 12, 21, 30 | input 3 : dose 1, dose 2, dose 3, dose 4 | ||
| pin 4, 13, 22, 31 | input 4 : dose 1, dose 2, dose 3, dose 4 | ||
| pin 5, 14, 23, 32 | input 5 : dose 1, dose 2, dose 3, dose 4 | ||
| pin 6, 15, 24, 33 | input 6 : dose 1, dose 2, dose 3, dose 4 | ||
| pin 7, 16, 25, 34 | input 7 : dose 1, dose 2, dose 3, dose 4 | ||
| pin 8, 17, 26, 35 | input 8 : dose 1, dose 2, dose 3, dose 4 | ||
| pin 9 | 12Vdc common for input switches, must be connected with pin 18 | ||
| pin 18 | detection auto/manual, must be connected with pin 9 |
The 36-way connector ( nearest to the front ) used for bypassing the system.
If this connection is used, the software will create a log for every time the the system is bypassed.
When you plug in the cable with the input connector ( described above ) here, the system is bypassed.
pin 1 to 8 is internally routed directly to output 1 to 8
pin 9 and 18 is internally connected to 24Vac.
Only the switches connected to dose 1 will work in bypass mode.
Software
Within the neuron program you can influence the behaviour of the node by setting different flags
Flags:
- MaxCount : maximum number of tap actions without resetting the input
- Pause : time between two tap actions
- Flags :
- Between 1 and 8: maximum number of valves opened at the same time
- 9: Handdouche (used for controlling Berg douche systems)
- WARNING: Never put the 36-way connector in manual mode when using the 32-8 as a Handdouche device!
- 10: Speedrail: 2 different amounts on 1 button
- Wait : time between double tap
The calibration value when an input is configured as STOP:
- Cal = 0: The input is a normal stop.
- Cal = 1: The input is a Hold-Resume. When the input is active, the output is paused until the input gets deactivated. Now the tap action will continue.
- Cal > 1: The input is a Stop-Start: on pressing, the tap action will stop. After pressing again, the tap action resumes with the set cal value for this STOP.
Warning
In the latest models of the 32-8 nodes is an triac print supplied that will be used when the 32-8 node is in manual mode. These triac modules can swith a current of maximum 1.5A. When using electric valves it's nececerry to remove this triac print.
