TOSHIBA 6F9EOlll Method of connection: Connection to the S2E21 is accomplished within the module. Connection with external circuits is made through the directional ground module terminal block 19 (clamp type). (1) The terminals for inputting the zero-phase current (lo) and the zero-phase voltage No) are classed as follows. Terminal number lo VO EA grounded ;+I D47, D48 system I D53. D54 I Capacitorvoltage-division D51.
TOSHIBA 6F9EOlll 4.2.6 Precautions for Connection (1) The control supply and sensor input (CT and ZCT secondary) should use twisted pair wires (twisted at less than 25 mm pitch). CT has a polarity, so be sure to check the polarity before making connection. The sensor input wires (ZCT, ZPD) entering the capacitor-voltage-division type directional ground module should be shielded wires. (2) Figure 10 shows an example external connection for the SZE21. Use this diagram as a reference in making connections.
TOSHIBA 5. 6F9EOlll HANDLING This chapter describes the procedure for starting and setting the S2E21 and for checking the condition of the motor. 5.1 Installing Battery The S2E21 incorporates a battery for backup of the internal calendar. Before use, be certain to remove an insulation sheet from the battery. The battery backs UP the internal calendar when the control supply for the S2E21 is interrupted. While the control-power is supplied, the-calendar works normally without the battery.
TOSHIBA 6F9EOlll 5.3 Basic Operation of Screen 5.3.1 Selection of Display The SZE21 employs a page selection type information access method whereby each display page is assigned with a particular kind of information and one can access any desired information by specifying the corresponding display page. The procedure for specifying a display page is given below. There are four (1)Specifying nethods for page specification. a page: Press [PAGEI [( )I I( )I [EXE1 keys. - Enter a desired page in ( ).
TOSHIBA 6F9EOlll (4)Redisplaying the current page: Press [PAGE] [EXE] keys. - The currently displayed page is shown again. 5.3.2 Entering Alphabets Keyboard is normally used to enter numerals. To enter alphabet inputs, follow the steps shown below. WEntering alphabets A to M: Press [ALPHA] key to move into the alphabet input mode. - LED on the upper left corner of [ALPHA] key lights up in red. In this state, the alphabets A-M appearing on the upper left corner of each key can be entered.
TOSHIBA 6F9EOlll 5.3.3 Changing Setting The setting values are important data to determine the characteristic of the protective units and the operation of the SZE21. to prevent inadvertent changes in this data. PASS ID system is incorporated Changing the setting values is allowed only after the registered PASS ID is entered. (1)Registering PASS ID: Registration of PASS ID is done on-PO SYSTEM DATA page. (a) Move the cursor to the PASS ID. PASS. ID. ------(h) Key in the currently registered PASS ID.
TOSHIBA 6F9EOlll (2)Changing setting values: Registered PASS ID must be entered before any change can be made to the setting values. (a) Call the PD SYSTEM DATA page. (b) Move the cursor to PASS ID. (c) Key in the registered PASS ID. (d) When the entered PASS ID matches the registered one, you are allowed to proceed to change the settings. (e) Call the setting page. (f) Press [EXE] Cursor appears. key. (When PASS ID does not agree or setting; change is not permitted. the cursor does not a.ppear.
