Pay attention to all cautions and warnings before using this product. Incorrect usage could lead to an electrical shock, damage to the unit or a fire hazard.
  • Page 2 TDK-Lambda EZA2500 series Quick Manual / Practical (II) • If the built-in fuse is blown, do not use the product even after replacing the fuse as there is risk of abnormality inside. Be sure to request repair to our company.
  • Page 3 TDK-Lambda EZA2500 series Quick Manual / Practical (II) Over view of Quick manual Practical Volume II In Quick Manual Practical Volume II, we will explain the procedure for actually operating the EZA2500 operation mode explained in Practical Volume I using the Windows GUI software CNVCommCC distributed by TDK Lambda.
  • Page 4 TDK-Lambda EZA2500 series Quick Manual / Practical (II) 1) Construction of communication environment with RS-485 The connection diagram for controlling EZA2500 with RS-485 is shown below. Since it is also described in Quick Manual basic version, if you have already referred to it, proceed to the next chapter.
  • Page 5 TDK-Lambda EZA2500 series Quick Manual / Practical (II) The setting procedure is shown below. ① Setting communication conditions for DIP switch and RS-485. Set the EZA to operation via RS-485 and the address on RS-485 to "0", the communication speed to 19.2 kbps.
  • Page 6 TDK-Lambda EZA2500 series Quick Manual / Practical (II) 2) Operation of Manual CV mode In this mode, charge / discharge switching is performed via RS485. The operation method is as follows. ①Start CNVCommCC. Start CNVCommCC and confirm that it can communicate with EZA.
  • Page 7 TDK-Lambda EZA2500 series Quick Manual / Practical (II) ④ Click the “Other settings” tab. ⑤Click “READ ALL” to display the current value of EZA. ⑥ Overwrite the parameters enclosed by the red line in the figure below if necessary and click “WRITE”.
  • Page 8 TDK-Lambda EZA2500 series Quick Manual / Practical (II) ③Start EZA. ① Click the "Main" tab. ② Turn on the radio buttons for “Heteronomy” and “With grid CC”. ③ Click “Grid CV” and the fan will rotate and start discharging. ④ Click “Battery CV” to switch to charging.
  • Page 9 TDK-Lambda EZA2500 series Quick Manual / Practical (II) 3) Manual Grid CV with battery CC mode operation ① Turn on the radio buttons for “Heteronomy” and “With batt CC” in ② of the previous operation. ②Perform the operations after ③ above.
  • Page 10 TDK-Lambda EZA2500 series Quick Manual / Practical (II) 4) Operation of Automatic grid CV mode In this mode, EZA automatically charges and discharges so that the grid voltage is the target voltage DVG.. ①Start CNVCommCC. Start CNVCommCC and confirm that it can communicate with EZA.
