10.8.1 POWER MANAGEMENT DISPLAY (PMD)
The user-friendly PMD consists of three parts the MIMIC DIAGRAM, CONTROL KEYS and LCD that provides the
necessary monitoring information about the UPS.
10.8.2 MIMIC DIAGRAM
The mimic diagram serves to give the general status of the UPS. The LED-indicators show the power flow status
and in the event of mains failure or load transfer from inverter to bypass and vice-versa the corresponding LED-
indicators will change colour from green (normal) to red (warning). The LED’s LINE 1 (rectifier) and LINE 2
(bypass) indicate the availability of the mains power supply. The LED’s INVERTER and BYPASS if green indicate
which of the two are supplying power to the critical load. When the LED-indicator BATTERY is lit it means that the
battery due to mains failure is supplying the load. The LED-indicator ALARM is a visual indication of any internal or
external alarm condition. At the same time the audible alarm will be activated
.
10.8.3 DISPLAY
The 2 x 20 character LCD simplifies the communication with the UPS. The menu driven LCD enables the access to
the EVENT REGISTER, or to monitor the input and output U, I, f, P, Autonomy Time and other Measurement’s, to
perform commands like start-up and shut-down of INVERTER or load transfer from INVERTER to BYPASS and
vice-versa and finally it serves for the DIAGNOSIS (SERVICE MODE) for adjustments and testing (for more details
see the USER MANUAL of POWERSCALE).
