Module Control Panel (standard LCD)

The standard KOHLER PW 6000 (400-500kVA) module is controlled and monitored through an LCD-based module
control panel located on the front of the cabinet. An alternative TFT touch screen, described in paragraph 2.6, is available.
By means the module control panel the operator can:
• Stop and start the UPS module
• Transfer the UPS output (load) between the inverter and bypass
• Monitor the UPS input/output voltage, current and frequency
• Monitor the battery charge/discharge voltage and current
• Monitor the battery status and autonomy time
• Interact with alarm and warning messages
• Configure the UPS operating parameters (service mode)*
• Interrogate the UPS events and alarm history (service mode)*
• Carry out diagnostic actions (service mode)*
• * Service mode features are for trained engineer use and password protected
The module control panel is composed of four parts, shown below:
Mimic LED indicators
2.5.1

Module mimic LED indicators

The module mimic LEDs change colour between GREEN, RED and OFF to
indicate the operational status of key UPS stages and thereby serve to show
the active power path through the UPS.
• LINE 1 (rectifier) and LINE 2 (bypass) LEDs indicate the availability of
the input mains and bypass mains supplies respectively.
• INVERTER and BYPASS LEDs illuminate green to indicate which of the
two sources is supplying the UPS output.
• BATTERY illuminates green when the battery is being charged and
flashes when the battery is discharging – e.g. when supplying the load
following a mains failure. The indications change to red when the
battery is faulty or fully discharged.
• The ALARM LED, located at the bottom centre of the control panel,
provides a visual indication that an internal or external alarm condition
has been detected. When an alarm condition is activated the LED is
accompanied by an audible alarm.
