This screen displays all vital UPS information in one convenient location. All of the
UPS monitoring functions and conditions are indicated here.
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.
Similar to the Up pad, this pad is used to move the cursor down through the
various selections present on the display screen.
After choosing the desired item (with highlighted cursor) from the display screen
with the Up and Down pads, pushing this pad tells the microprocessor to go to the
highlighted selection.
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.
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.
This pad activates the circuits that connect the UPS 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.
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.
This pad must be pressed simultaneously with the UPS, Bypass, Battery Trip or
Output Trip pads to activate them.
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.
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.
During an emergency, pressing this guarded switch will transfer the load to bypass
and then shut down the UPS modules. The load will remain on bypass power.
(Refer to 3.4.5 - Shutdown Procedures.)
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).
This pad can be used (along with Control Enable) to trip the module output circuit
breaker open (disconnecting the module from the UPS system).
