Figure 10 Series 600T UPS and SCC Operator Control Panels

Item	Description (Location)	Function
1	Display Screen	This screen displays all vital UPS information in one convenient location. All of the UPS
	(SCC and modules)	monitoring functions and conditions are indicated here.
2	Up	This touch-sensitive pad (button) is used to move the cursor up through various
	(SCC and modules)	selections present on the display screen. Note that all pads on this control panel have
		touch-sensitive switches behind them.
3	Down	Similar to the Up pad, this pad is used to move the cursor down through the various
	(SCC and modules)	selections present on the display screen.
4	Select	After choosing the desired item (with highlighted cursor) from the display screen with
	(SCC and modules)	the Up and Down pads, pushing this pad tells the microprocessor to go to the
		highlighted selection.
5	Alarm Reset	This pad is used to clear all of the alarm conditions that are no longer present.
	(SCC and modules)	However, all active alarms remain in memory and on the applicable screens until they
		are corrected. This pad also resets the History Status Report memory buffer when held
		until the screen clears.
6	Voltage Adjust	This push-to-turn knob permits adjustment of the UPS output voltage to meet load
	(SCC only)	requirements or to match the bypass voltage before transferring the load to or from
		bypass.
7	UPS	This pad activates the circuits that connect the UPS to the critical load (a retransfer).
	(SCC only)	When this pad is pushed (along with Control Enable), the UPS output circuit breaker
		closes and the bypass circuit breaker opens.
8	Bypass	This pad activates the circuits that connect the bypass line to the critical load (a
	(SCC only)	transfer). When this button is pushed (along with Control Enable), the bypass circuit
		breaker closes and the UPS output circuit breaker opens.
9	Control Enable	This pad must be pressed simultaneously with the UPS, Bypass, Battery Trip, or Output
	(SCC and modules)	Trip pads to activate them.
10	Horn Off	This pad is used to silence the alarm horn after it is activated. When this switch is
	(SCC only)	pressed, the alarm horn is silenced but the active and latched alarm messages remain
		on the screen. The alarm messages still displayed stop flashing to indicate they have
		been acknowledged.
11	Alarm Horn and	This electronic horn sounds to alert nearby personnel whenever a new alarm occurs. A
	Red LED (SCC only)	red LED (light emitting diode) is located in the middle of the alarm horn.
12	Emergency Module	During an emergency, pressing this guarded switch will transfer the load to bypass and
	Off (SCC only)	then shut down the UPS modules. The load will remain on bypass power. (Refer to
		3.3.3 - Shutdown Procedures.)
13	Battery Trip	This pad can be used (along with Control Enable) to trip the module battery disconnect
	(modules only)	(MBD) circuit breaker open (disconnecting the battery from the UPS module).
14	Output Trip	This pad can be used (along with Control Enable) to trip the module output circuit
	(modules only)	breaker open (disconnecting the module from the UPS system).
