ICS TRIPLEX 9832工控模塊系統(tǒng)備件
如果R2輔助設(shè)備用于上游跳閘，則其也不能用于控制降壓?jiǎn)?dòng)。類似地，如果R3專用于繼電器，以將所有報(bào)警條件反饋給PLC，則它也不能嚴(yán)格用于發(fā)出特定報(bào)警，如欠電流。為了確保中繼分配中不發(fā)生沖突，已采取了若干預(yù)防措施。除短路備用跳閘外，所有跳閘默認(rèn)為R1跳閘輸出繼電器。所有報(bào)警默認(rèn)為R4報(bào)警繼電器。R2和R3輔助繼電器僅默認(rèn)具有特殊控制功能。建議在所有設(shè)定點(diǎn)編程完成后，對(duì)這些分配進(jìn)行審查。重置4-6 469電機(jī)管理繼電器GE Multilin 4.2 S1 469設(shè)置4設(shè)定點(diǎn)4 4.2S1 469設(shè)定4.2.1密碼路徑：設(shè)定點(diǎn)S1 469設(shè)定點(diǎn)密碼除設(shè)置點(diǎn)訪問跳線外，還提供密碼訪問安全功能。出廠時(shí)，密碼默認(rèn)為0。當(dāng)密碼為0時(shí)，將忽略密碼保護(hù)。在這種情況下，只需要設(shè)置點(diǎn)訪問跳線即可從前面板更改設(shè)置點(diǎn)。通過RS485端口編程設(shè)定點(diǎn)時(shí)，密碼也會(huì)被忽略。但是，使用前RS232端口和469PC軟件編程設(shè)定點(diǎn)，需要密碼（如果啟用）。要在新繼電器上啟用密碼保護(hù)，請(qǐng)遵循以下步驟：1。然后按下直到更改密碼？顯示消息。2.選擇“Yes”（是）并按照說明輸入長(zhǎng)度為1至8位的新密碼。3.一旦密碼（“0”除外）被編程，則每次限制設(shè)置點(diǎn)訪問時(shí)都必須輸入密碼。如果編程了非零密碼并且限制了設(shè)置點(diǎn)訪問，則在進(jìn)入S1 469 SETUP（設(shè)置）密碼子組時(shí)，將顯示ENTER passcode FOR access（輸入密碼用于訪問）消息。4.輸入正確的密碼。如果代碼不正確，將顯示一條閃爍消息，并允許重試。如果密碼正確且安裝了設(shè)定點(diǎn)訪問跳線，則會(huì)顯示setpoint access：Permitted（設(shè)定點(diǎn)訪問：允許）消息。5.現(xiàn)在可以輸入設(shè)定值。按下退出S1 469 SETUP（設(shè)置）PASSCODE（密碼）組并編程相應(yīng)的設(shè)定點(diǎn)。如果5分鐘內(nèi)沒有按鍵，將不再允許編程訪問，并且必須重新輸入密碼。移除設(shè)置點(diǎn)訪問跳線或?qū)⒃O(shè)置點(diǎn)訪問設(shè)置點(diǎn)設(shè)置為“受限”也將立即禁用設(shè)置點(diǎn)訪問。如果需要一個(gè)新的密碼，通過如上所述輸入有效的密碼來獲得設(shè)置點(diǎn)訪問權(quán)限，然后按下以顯示CHANGE passcode（更改密碼）消息并遵循指示。如果輸入了無效的密碼，則可以通過按鍵查看加密的密碼。
if R2 Auxiliary is to be used for upstream trips, it cannot also be used for the control of a Reduced Voltage Start. Similarly, if R3 is to be dedicated as a relay to echo all alarm conditions to a PLC, it cannot also be used strictly to enunciate a specific alarm such as Undercurrent. In order to ensure that conflicts in relay assignment do not occur, several precautions have been taken. All trips with the exception of the Short Circuit Backup Trip default to R1 Trip output relay. All alarms default to the R4 Alarm relay. Only special control functions are defaulted to the R2 and R3 Auxiliary relays. It is recommended that these assignments be reviewed once all the setpoints have been programmed.

PASSCODE A passcode access security feature is provided in addition to the setpoint access jumper. When shipped from the factory, the passcode is defaulted to 0. Passcode protection is ignored when the passcode is 0. In this case, only the setpoint access jumper is required for changing setpoints from the front panel. Passcodes are also ignored when programming setpoints via the RS485 port. However when programming setpoints using the front RS232 port and the 469PC software, a passcode is required (if enabled). To enable passcode protection on a new relay, follow the procedure below: 1. Press then until the CHANGE PASSCODE? message is displayed. 2. Select “Yes” and follow the directions to enter a new passcode 1 to 8 digits in length. 3. Once a passcode (other than “0”) is programmed, it must be entered each time setpoint access is restricted. If a nonzero passcode has been programmed and setpoint access is restricted, then the ENTER PASSCODE FOR ACCESS message appears when entering the S1 469 SETUP ? PASSCODE subgroup. 4. Enter the correct passcode. A flash message will advise if the code is incorrect and allows a retry. If the passcode is correct and the setpoint access jumper is installed, the SETPOINT ACCESS: Permitted message appears. 5. Setpoints can now be entered. Press to exit the S1 469 SETUP ? PASSCODE group and program the appropriate setpoints. If no keys are pressed for 5 minutes, programming access will no longer be allowed and the passcode must be re-entered. Removing the setpoint access jumper or setting the SETPOINT ACCESS setpoint to “Restricted” will also immediately disable setpoint access. If a new passcode is required, gain setpoint access by entering the valid passcode as described above, then press to display the CHANGE PASSCODE message and follow directions. If an invalid passcode is entered, an encrypted passcode may be viewed by pressing the key.
