PowerWAVE 9000 DPA UPS - Specifications
(Issue 2.1 Oct. 2009)
10.6 Power Management Display (PMD)
The user-friendly PMD consists of three parts, the MIMIC DIAGRAM,
CONTROL KEYS, an LCD which provides monitoring information about
the UPS.
10.6.1 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.
10.6.2 Pushbuttons
The push buttons serve to manage the UPS by performing commands. The
2xON/OFF push buttons serve to start-up or shutdown the UPS if pressed
simultaneously. The UP and DOWN push buttons allow selection through
the Power Management Display-menu. The RESET push button serves to
cancel the audible alarm in the event of a disturbance. If the alarm
condition was only transient the LED-indicator ALARM will extinguish
otherwise it will remain illuminated (red).
10.6.3 Display
The 2 x 20 character LCD simplifies the communication with the UPS. The
menu driven LCD enables access to the EVENT REGISTER, or to monitor
the input and output voltage, current, frequency, power, 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.
It also enables access to the DIAGNOSIS (SERVICE MODE) for
adjustments and testing.
