Table 3 Liebert Series 610 UPS and SCC operator control panels
Item Description (Location) Function
1
Display Screen
(SCC and modules)
This screen displays all vital UPS information in one convenient location. All of the
UPS monitoring functions and conditions are indicated here.
2
Up
(SCC and modules)
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
(SCC and modules)
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
(SCC and modules)
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.
5
Alarm Reset
(SCC and modules)
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
(SCC only)
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
(SCC only)
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.
8
Bypass
(SCC only)
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
Control Enable
(SCC and modules)
This pad must be pressed simultaneously with the UPS, Bypass, Battery Trip or
Output Trip pads to activate them.
10
Horn Off
(SCC only)
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.
11
Alarm Horn and
Red LED (SCC only)
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.
12
Emergency Module
Off (SCC only)
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.)
13
Battery Trip
(modules only)
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).
14
Output Trip
(modules only)
This pad can be used (along with Control Enable) to trip the module output circuit
breaker open (disconnecting the module from the UPS system).
