LED Indication summary
2.6.2 Operator buttons
The operator buttons allow the user to:
• Set operating parameters and make adjustments via the menu-driven LCD display.
• Start and stop the UPS, and transfer the load between inverter and bypass.
• Monitor the UPS input/output voltage, current, frequency and other parameters – shown on the LCD display.
Button function summary
The UPS can be switched
ON
or
OFF
by simultaneously pressing both
ON/OFF
buttons. The requirement to press both
buttons is to help avoid accidental operation.
During normal operation, simultaneously pressing the two
ON/OFF
buttons will shut down the UPS module.
• In a single UPS module installation this will disconnect the UPS output unless the load is first transferred to the
maintenance bypass – see the operating instructions.
• In a parallel module system the UPS module will shut down and its output will be disconnected from the parallel
load bus. However, the load may or may-not transfer to bypass depending on the number of remaining live
modules – i.e. if the number of remaining modules is sufficient to support the connect load then the load will not be
transferred.
To shut down all the modules in a parallel system you must press both
ON/OFF
buttons on every module.
