Product Description 

LP 31 Series

 

The ‘

default screen’

 shows UPS model and actual load (values are examples): 

 

 

LP 15-31 

 

LOAD  37% 

 
The 

'information screens'

 show the UPSs system data: 

-  Mains voltage, mains frequency and the power delivered by the mains. 
-  Output voltage and output frequency, and the power delivered by the UPS. 
-  Power factor, crest factor and peak currents of the connected equipment. 
-  Temperature near the batteries, battery voltage and battery (dis)charging current. 
-  Remaining autonomy time (during mains failure). 
-  The total operating time of the UPS 
The 

'setup screens'

 show a programmable UPS function and its actual setting: 

-  System operating frequency. 
-  System operating voltage. 
- Battery 

capacity. 

- No-load 

shutdown 

(<2%). 

- Bypass 

enable/disable. 

-  Frequency tracking range. 
The 

'service screens'

 show service information targeted on trained service personnel: 

-  Serial number of the UPS, release number of the installed software. 
-  Service information on internal components, fan speed, internal DC voltage, internal temperature 

levels, peak input voltage, mean (bypass) input voltage, mean output voltage. 

-  Start of a quick battery test. 
-  Forced (manual) transfer to bypass. 
The 

'test screens'

 show the proceeding of the following tests: 

-  General system test. 
- Quick 

battery 

test. 

-  Battery calibration test. 
- Bypass 

test. 

 
 
 
 
 

3.3 Alarm Conditions 

 
The LCD screen on the front panel displays status messages and alarm messages. 
Three kinds of messages can be recognized. 
-  Status indications 

indicate the UPS operating mode. 

- Low 

priority 

alarms 

indicate 

abnormal operating situations; the screen message is accompanied by 

a 1x per sec. blinking red LED and a 1x per 8 seconds. sounding buzzer, resettable. 

-  High priority alarms 

indicate situations in which the connected load is at risk as a 

proper 

output voltage of the UPS is no longer guaranteed

; immediate action 

should be taken. 

 

The screen message is accompanied by a 1x per sec. blinking red 
LED 

'alarm'

 and a 1x per second sounding buzzer, resettable. 

 

Note: By using ComConnect, additional conditions can be monitored and signals include written screen 
messages (see section 5, Interfacing).
