5.3.1 Inverter Mode Status Messages
There are several Inverter mode messages. View the top line of the LCD
display and the corresponding message in this section to determine and
understand the particular Inverter mode.
• Inverting
– The inverter is providing AC voltage on its output by
inverting power from the batteries.
• Inverter
Standby
–
The inverter is on but not actively providing power.
However, the inverter remains active and an external AC power (utility or
generator) is passing through the inverter to power the AC loads.
• No Inverter Comm
– The remote is not receiving any communication
data via the Magnum Network.
Remedy:
Disconnect the remote communications cable from the
inverter for
fi
ve seconds, and then reconnect to reset the remote
(see Figure 2-2). If the fault continues, examine the remote cable
for damage, and replace if needed (4-wire telephone cable).
What if the cable is not the issue?
• Try another remote display
• Move the remote cable from the Remote port to the
Network port
• The inverter may need servicing
• Off
– This message tells you that there is no AC available on the
inverter’s AC output. The inverter function is OFF, and there is no utility or
generator AC power sensed on its input.
• Searching
– The inverter is in Search mode. This means the AC loads
on the inverter output are less than the
SETUP: 01 Search Watts
setting. The
Search mode function is used to reduce the inverter draw from the battery
when the inverter loads are off. Turn the Search mode off if you want full
inverter output voltage available at all times (see the Search Watts section).
• Unknown
Mode
##
– This status displays when the inverter/charger
has sent an operational status code that the RC remote does not identify.
Remedy:
Call Technical Support at Sensata Technologies for
assistance in identifying and understanding the actual status.
5.3.2 Charger Mode Status Messages
When AC power (utility or generator) is connected to the inverter/charger, it
begins to monitor the AC input for acceptable voltage. Once the AC input is
accepted, the AC transfer relay (inside the inverter) closes and charge mode
begins. There are ten Charger mode status messages. View the top line of
the LCD display and the corresponding message in this section to identify
and understand the particular Charger mode.
Info:
The AC input becomes acceptable after a minimum 12-second
input qualifying delay and the voltage is greater than the
SETUP:
06 VAC Dropout
setting.
• Absorb
Charging
– The Absorb charge state is the constant voltage
stage and begins when the absorb voltage is reached (determined by the
SETUP: 04 Battery Type
setting) while Bulk charging. During this stage, the
DC charging current decreases in order to maintain the absorb voltage setting.
This charge stage continues until the absorb charging time (determined by
the SETUP menu’s
03 Absorb Time
setting) is
fi
nished.
