Enerdrive ePRO COMBI Owners Manual Page 14
Four flashes in a row : Device error (an error has occurred inside the ePRO Combi. Please return for
service)
Five flashes in a row : Charge program error (only for ‘charger on’ indicator LED). Charge program
selection set to Custom, while custom made charge program contains an error
or time-out.
The ePRO Combi will mostly recover from an error mode automatically when the cause of the error has been
resolved. However, when an error has occurred due to a high battery ripple voltage or an AC transfer switch
overcurrent, a manual reset of the ePRO Combi will be necessary. The ePRO Combi also needs to be reset
manually, when too many battery or overload errors have occurred within a short period of time.
4.3 ALARM RELAY
The ePRO Combi is equipped with a potential free alarm relay. Standard, this relay will be activated when the
unit shuts down and jumps to an error mode. The alarm relay de-activates again when the error has been
resolved and the ePRO Combi is running in normal operating mode again.
Using Dashboard, it is also possible to configure the alarm relay to perform a different task, like starting a
generator when the battery voltage has reached a certain low voltage level.
On pins 1, 2 and 3 of the 7 pins screw terminal located in the connection compartment, both normally closed
and normally open contacts are available. Please make sure not to exceed the maximum relay contact rating of
30V/1A or 60V/0.5A, in order to avoid damaging the relay.
4.4 TRIGGER INPUT
The trigger input offers a way of externally controlling the behaviour of the ePRO Combi. The trigger input can
be connected to an external switch or a potential free relay contact. Closing this external switch or contact,
a user programmable ‘action’ will be performed. Such an action could be to release the AC transfer switch,
temporarily disable the AC input Power Boost feature or force the ePRO Combi to switch to inverter mode. All
this can be configured in Dashboard.
4.5 LOAD REQUIREMENTS IN INVERTER MODE
Before you connect your appliance(s) to the ePRO Combi AC output, always check it’s maximum power
consumption. Do not connect appliances to the AC output requiring more than the nominal power rating
of the inverter continuously. Unless these appliances are switched on only when the AC transfer switch is
activated, and power is drawn from an external source with a larger capacity than the inverter.
Some appliances like motors or pumps, draw large inrush currents at startup. It is possible that the startup
current exceeds the overcurrent trip level of the inverter. In this case the output voltage will shortly decrease
to limit the output current of the inverter. If the overcurrent trip level is continuously exceeded, the inverter will
shut down and automatically restart within 20 seconds. In this case it is advisable to disconnect this appliance
from the inverter, since it requires to much power to be driven by this unit. The ePRO Combi needs to be
restarted manually when it has shut down due to overloads for four times in a row. Note that at higher ambient
temperature levels, the overload capacity of the ePRO Combi will be reduced.
