STATUS MESSAGES LEVEL
This group of messages provides the user with general information on the status of the device. The following
messages may be displayed:
ON PREFERRED: this message indicates that the source selected as preferred is switched onto the STS
output (the load is being supplied by the preferred source)
ON ALTERNATIVE: this message indicates that the non preferred (alternative) source is switched onto the
STS output.
Possible causes of this message include: preferred source outside the limits and therefore not suitable, or a
manual transfer has been carried out onto the alternative power source
MANUAL XFER: this message indicates that the load has been manually switched
MANUAL BP S1: this message indicates that the load is connected directly to source 1 via the bypass switch
MANUAL BP S2: this message indicates that the load is connected directly to source 2 via the bypass switch
OUTPUT INHIBIT:
this message indicates that no voltage is present on the STS output.
Possible causes of this message include: both input sources source 1 and source 2 are outside the specified
limits, or transfer with asynchronous mains is disabled
EMERGENCY STOP: this message indicates that the EPO (Emergency Power Off) command has been given
and the STS output has been switched off. To reset the STS, both automatic input switches SW1 and SW2
have to be opened and then closed
OVERLOAD INHIBIT:
this message indicates that an extended overload has occurred in output and activated
the overload protection, therefore the STS output is currently off until the alarm is reset.
This is only possible if the overload sensor is enabled, otherwise the output would not be opened.

MEASURES MENU
This menu is used to monitor and control all the STS parameters and measurements.
The STS can provide the following data:
S1: 230 225 235
S2: 230 225 235
LD%: 045 050 060%
OPI: 090 100 120°
TEMP: 030 C°
S1-FREQ: 50,0 Hz
S2-FREQ: 50,1 Hz
SYNC.ANG: 001 Deg
PS 1=OK 2=OK
- Phase-neutral voltage of the input source S1
- Phase-neutral voltage of the input source S2
- Percentage of the load on the output for each phase U,V,W
- Value of the STS output current for each phase
- STS heat sink temperature
- Frequency of source S1
- Frequency of source S2
- Phase difference between the two input sources; this value is
expressed in angular degrees
- Value of the direct voltages being output by the two redundant power
supplies inside the STS.
If the value is OK , the power supplies are working correctly.
If the value is N.OK , it is necessary to replace the faulty power supply.
