Automatic change-over device type IVPS

Operation
The Automatic change over device switches automatically
between the three AC sources.
The input is taken from output of Generator, Shore Power and
Inverter. In case of failure of generator the shore power will take-
over. If shore power and generator fail, inverter will take over.
The Vetus IVPS has a built-in micro controller to control the
relays and indicators. The micro controller is used to choose
the best source of power based on two choices: the prior-
ity of the power source, and the voltage of the power source.
For example, if the shore power and generator are both avail-
able, the generator power will have priority. But if the voltage of
the generator power is too low or too high, then the priority of
the generator is not considered, and the shore power is used.
The acceptable voltage of the shore power and generator is
230 V AC –20% and +10%. This means the voltage must be
between 184 V and 253 V.
In case the output is switched to shore power or inverter and the
generator is switched-on (manual) a delay can be a set to give
the generator time to start-up. Generator time delay is adjustable
from 1 to 30 seconds.

Possible cause
Solution
LED ‘Generator IN’ off
No output from the generator.
Switch ON the generator and check the output.
Connection fault.
Check the connections of the generator to IVPS.
LED printed circuit board connection
broken.
Contact service department.
LED ‘Shore power IN’ off
No output from the shore power.
Switch ON the shore power and check the output.
Connection fault.
Check the connections of the shore power to IVPS.
LED ‘Inverter IN’ off
No output from the inverter.
Switch ON the inverter and check the output.
Connection fault.
Check the connections of the inverter to IVPS.
LED ‘Generator IN’ on,
But output powered from Shore
Power
Generator output voltage is not within
the limits (too low or high)
Check voltage of the generator.
Module fault.
Contact service department.
LED ‘Shore power’ on But
output powered from the
inverter.
Shore power output voltage is not
within the limits (too low or high)
Check the voltage of the shore power.
Module fault.
