Item Description Function
1 Display Screen
This screen displays all vital UPS information in one convenient location. All of the UPS
monitoring functions and conditions are indicated here.
2 Up
This touch-sensitive pad (button) is used to move the cursor up through various
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
selections present on the display screen.
4 Select
After using the Up and Down pads to move the highlighted cursor to the desired menu
item on the display screen, push this pad to tell 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. However,
all active alarms remain in memory and on the applicable screens until they are
corrected.
6 Voltage Adjust
This push-to-turn knob permits adjustment of the UPS output voltage to meet load
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 inverter to the critical load (a
retransfer). 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
transfer). When this button is pushed (along with Control Enable), the bypass circuit
breaker closes and the UPS output circuit breaker opens.
9 Battery Trip
This pad can be used (along with Control Enable) to trip the module battery disconnect
(MBD) circuit breaker open (disconnecting the battery from the UPS module).
10 Control Enable
This pad must be pressed simultaneously with the UPS, Bypass or Battery Trip pads to
activate them.
11 Horn Off
This pad is used to silence the alarm horn after it is activated. When this switch is
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.
12 Alarm Horn and Red LED
This electronic horn sounds to alert nearby personnel whenever a new alarm occurs. A
red LED (light emitting diode) is located in the middle of the alarm horn.
13 Emergency Module Off
During an emergency, pressing this guarded switch will transfer the load to bypass and
then shut down and disconnect the UPS inverter, rectifier and battery. The load will
remain on bypass power. (Refer also to 3.4.4 - Shutdown Procedures for additional
performance options.)
