4.7.1.3. VOLTAGE ALLARM
TPS controls, in addition to the harmonic distortion, the RMS value of the output voltage both in
2WIRE and in 4WIRE configuration.
If the output voltage is not equal to the set value, a special alarm is generated (MAX DV OUTX).
VOLTAGE ALARM does not cause any stop.
4.7.1.4. INVERTER COMMUNICATION
The alarm appears when there is problem on the communication between the inverter and the
display.
4.7.1.5. BUS OVERVOLTAGE & UNDERVOLTAGE
TPS can work with network voltage variations of

10%, if these limits are exceeded TPS stops and
show the alarm.
If the network voltage is too low TPS stops and the
UNDERVOLTAGE alarm is on.
If the network voltage is too high TPS stops and the OVERVOLTAGE alarm is on.
If the supply phases have been inverted, both the UNDERVOLTAGE and OVERVOLTAGE alarms
are generated. Check
POWER CABLING and invert the phases on the input connector.
4.7.1.6. OVERTEMPERATURE
The alarm appears in case of high temperature inside of TPS. TPS stops and the
OVERTEMPERTURE alarm is active
4.7.1.7. INVERTER ALARM
In case of bad operations of the overload sections (inverter) TPS stops and the
INVERTER alarm is
active
