How to operate CB Close/Open

① Go to SYSTEM CONFIG menu on the initial screen.

② Then go to RELAY CONFIG menu in the SYSTEM CONFIG.

③ Generate a cursor, and put the value to where you want to input.

※ The confirmation for the setting values can be done by following ①~④ process.

(After confirm, press to go back to the initial screen.)

* When it is not operated for 15minutes while the password hasbeen released, the lamp on the LCDscreen will be off and it will be lockedagain (But checking correctionvalue/measurement value is stillavailable regardless of the password)

* When approving the DC power againafter turn it off, it requires thepassword input.

Operation

1) It works by pressing the Close / Openbutton of the relay twice.

2) ⑤ operation should be conducted whilethe ④ is indicated on the indication screen.

3) When the password is released, ② , ③

processes will be skipped and Close /Open operation will be conducted through① , ④ and ⑤ processes.

4) The password is required only wheninputting correction values, conductingcontrols, and rebooting.

※ Checking status and measurement value monitoringwill be still available without password.

How to set relay elements

●Setting Items

① INSTANTANEOUS: Indicates instantaneous elements

② Indicates the instantaneous action time, and setting range can beselected up to 30~250ms

③ Indicates the instantaneous current TAP value, and set by samemethod of the ③-1.

③-1 Indicates time delay current TAP value, and means the multiplesof the CT ratio.ex) When the CT ratio 100/5, and the correction value is 0.8In as

in the picture In indicates CT ratio, and 0.8 is the multiple.Therefore, the correction value is...�Based on CT 1st: 0.8 X100 (CT 1st rating) =80A�Based on CT 2nd: 0.8 X5 (CT 2nd rating) =4A

④Time Delay: Indicates the time delay element.

⑤ It is an item to select characteristic curve. In GIPAM, it supportsDefinite-time (DT) and 7 curves of inverse time (SI, VI, EI, LI, KSI,KVI).

⑥This is an item to select the Time Lever. The setting ranges are up to0.05~1.2 and can select in 0.01 units. (Can only be corrected whenselecting inverse time curve at ⑤)

⑦When the definite time curve (DT) is selected at ⑤, Time Levercorrection as shown in the picture above is not possible.

⑧ Indicates the definite time operation time, and the setting range canbe selected up to 0.05~300.00sec.

⑨ This item indicates the Constant Time Delay, and can be selected upto 0.0~10.00sec. (Can only be corrected when selecting the inversetime curve at ⑤)�When selecting the Time Lever, if protection is not possible because

the relay’s operation characteristic curve is on the load characteristiccurve, even though the Lever is selected to its maximum, increasethe relay’s operation characteristic curve to delay the operation timeas much as the changed time in this item.

※For some of delay elements such as OCR and OCGR, can be set bysynthesizing Low and High curves considering the characteristics ofthe loads.
