4. Electrical interface
1.Input port
Connector:PC 5/ 3-STF1-7,62 – 1777846
2.Output port
Connector:PC 5/ 3-STF1-7,62 – 1777846
3.Control port A
Connector:Phoenix MC 0,5/8-G-2,5
Connected with PLC IO,Read “5-control way”
4.Control port B
Connector:Phoenix MC 0,5/7-G-2,5
CAN BUS, RS422/RS485 Communication interface. Read “5-control way”
5.Control way
This Model ballast has three control ways of PLC I0 Hard wire, CAN Bus communication, RS485/RS422 BUS Communication, chosen by code switch.
As code switch shows above, it stands for number 17.
Number meaning on Code switch
Code switch value | Control way |
0 | hard wire control |
Non O | CAN bus/RS422 bus communication control Code switch value is the communication address
|
1.Hard wire control
Control port A connected with IO of the PLC,using the PLC to control the ballast.
1.1 pin definition
Pin | Function | Direction | Type | Description |
1 | PLC COM (0V) | Input | 0V | the cathode of external power |
2 | Must Dangling |
|
|
|
3 | Fault code 1 | Output | Open connector |
Low level means fault(driver fault) |
4 | Fault code 2 | Output | Open connector | Low level means fault(system fault) |
5 | Fault code 3 |
Output | Open connector | Low level means fault(indicator light fault) |
6 | START/STOP | Input | 24V | The anode of external power |
7 | Lamp light on signal | Output | Open connector | Low level means lamp works |
8 | Dimming control | Input | PWM | Duty ratio controls power |
1.2 Controller PLC connecting wire grid
1.3 lighting
1.3.1 Control port A Pin 6 connect with 24V, ballast starts output.
1.3.2 lights on all, control port A Pin 7, output low level
1.4 Dimming control
Exterior PWM signal enters into Ballast, ballast starts dimming control. PWM signal frequency scale: (1KHZ-3KHZ)
PWM Duty ratio | Lamp Power |
<10% | 450W |
10% | 450W |
97% | 3000W |
100% | 3000W |
2.CAN bus control way
Read “LPCU-1PH-A-3 CAN OPEN”protocol
3.RS422/RS485 bus control way
Read “LPCU-1PH-A-3 MODBUS”protocol
6. LED lamp indication
The ballast has five led indicator lights.
Name | Description |
RUN | Supply power, “RUN” Lights on, ballast operates. |
LAMP | Indicator light flashes, lamp is on the process of lighting on. Indicator light on stably, lamp finishes starting. Indicator light off, lamp off. |
FAULT | Indicator light on, fault happens. (Ballast default or lamp default) |
TX | Indicator light flashes, communication data is sending. (CAN BUS OR RS485 BUS) Indicator light doesn’t flash, no data is sending. |
RX | Indicator light flashes, communication data is accepting. (CAN BUS OR RS485 BUS) Indicator light doesn’t flash, no data is accepting. |
