Bluelight Electrical Brake Release Device Update
Bluelight JT-EPB electric brake has been upgraded to SJT-EPD due to changes in domestic standards, type testing rules, and inspection and testing rules in China. The corresponding models are as follows：
Original Model | Upgraded Model |
SJT-EPB110PN | SJT-EPD110PN |
SJT-EPB110NN | SJT-EPD110NN |
SJT-EPB220PN | SJT-EPD220PN |
SJT-EPB220NN | SJT-EPD220NN |
SJT-EPB110PT | SJT-EPD110PT |
SJT-EPB110PS | SJT-EPD110PS |
SJT-EPB220PS | SJT-EPD220PS |
SJT-EPB110PF | SJT-EPD110PF |
SJT-EPB220PF | SJT-EPD220PF |
The SJT-EPB series are single brake output, while the SJT-EPD series are double brake output. The numbers and letters that follow have same meaning.
The changes of terminal definition are as follows,
1. The definition of the original J1 high-voltage terminal J1-1~4 has no change, adding J1-5 and J1-6 as the second brake power output, where J1-5 is "+" and J1-6 is "-". If double brake function is not required, the original J1 terminal can be kept unchanged and connected to J1-1~4 terminals；
2. For the original J3 low-voltage terminal, terminal definition and wire sequence has no change. But the spacing has been adjusted from 5.08 to 3.81. When replacing it on site, the terminal plug needs to be replaced.
The new model of electric brake release SJT-EPD is fully compatible with the original SJT-EPB electric brake release, except for the changes in the J1 terminal definition and J3 terminal specifications mentioned above. Therefore, after upgrading the original SJT-EPB electric brake release to the new SJT-EPD electric brake release, it has no impact on the installation and application of your company's products, and the debugging method is completely the same as the previous product.
