Figure 2 | Description | Purpose and Use |
1 | SOURCE PREFERENCE AND RETURN MODE | Selects either Source I (PREF I) or Source II (PREF II) as the |
| Switch (S4) (See Note A) | preferred source, or no preference (NO PREF). Also selected |
|
| parallel (P) or |
2 | SOURCE I ENERGIZED lamp | Indicates all three phases of Source I are energized. |
3 | OPERATION SELECTOR Switch (S3) | Programs control for either AUTOmatic or MANUAL operation. |
4 | PREFERRED TO ALTERNATE TIMER | Determines time delay before transfer to alternate source when |
|
| preferred source voltage is lost. |
5 | SWITCH I OPEN and CLOSED lamps | Indicates status of Source I high voltage switch. |
6 | LAMP TEST switch (S6) | Tests all indicating lamps on front panel. |
7 | LATCH RELAY STATUS TEST terminals | Provides electrical access to both sides of latch relay to |
| (T1— T2— T3) | determine if control is in Source I or Source II mode. |
8 | SWITCH II OPEN and CLOSED lamps | Indicates status of Source II high voltage switch. |
9 | ALTERNATE TO PREFERRED TIMER | Determines the time delay before transfer to preferred source |
|
| when preferred source voltage is restored. |
10 | MANUAL OPER. SOURCE I and MANUAL OPER. | Provides means to OPEN and CLOSE Source I and Source II |
| SOURCE II switches (S1 and S2) | transfer switch upon manual command, when S3 is in MANUAL |
|
| position. |
11 | SOURCE II ENERGIZED lamp | Indicates all three phases of Source II are energized. |
12 | CONTROL MODE switch (S5) | Blocks automatic return transfer to preferred sources (HOLD ON |
|
| ALTERNATE); also enables control to be operated without |
|
| operating the high voltage transfer switches (TEST). |
13 | Indicates | |
14 | RESET switch (S7) | Resets the control after a fault block operation (part of |
|
| accessory). S3 must be in MANUAL position. |
15 | Fuses | Voltage input of all three phases of both Source I and Source II |
|
| are fused for |
|
| fuse blows. |
|
|
|
Note A — Tab provided to lock switch knob in set position; stop screw prevents inadvertent selection of parallel return transfer mode.
