Status Description
Absorb Charging
[Absorb]
This charging stage begins after the absorb voltage has been reached.
Absorb charging provides the batteries with a constant voltage and reduces
the DC charging current to maintain the absorb voltage setting.
Bulk Charging
[Bulk]
This is the initial stage of charging. While bulk charging, the charger supplies
the battery with controlled constant current. The charger will remain in
bulk charge until the absorption charge voltage is achieved.
Charger Off
[Chg Off]
Charging in the PT controller has been disabled manually by selecting Charger
Off from the 04A PT CHG Ctrl menu, or may be caused by a controller fault.
EQ
[ EQ]
Battery equalization is in process and the PT controller is trying to maintain
the battery at the equalize target voltage.
Float Charging
[Float]
The third charging stage occurs at the end of the Absorb charge stage.
The charge voltage is reduced to the
fl oat charge voltage and kept fully
charged—unless the battery type is CC/CV.
When the battery type is CC/CV the controller stops charging, but is actively
monitoring the battery voltage. If the battery voltage drops to the Set
Recharge Volts setting, another Constant Current (Bulk)/Constant Voltage
(Absorb) charge cycle begins.
Sleeping
[Sleeping]
The PV controller is not charging the battery because either the PV has
been turned off, or it has determined that there is no sun (i.e., nighttime).
Note: “ No sun” is based on low PV voltage and no effective power (i.e.,
nighttime).
Unknown Status
##
[UnkS ##]
This status message displays when the inverter/charger has sent a status
code that cannot be determined by the ME-ARTR router.
12.2.4 PT Charge Controller Router Status Messages
A PT status may be an operational, relay, fault, or power status message. The METER: 07A PT
Status menu displays the PT’s current operating status. This menu is important when determining
if the PT is working correctly, or for troubleshooting a PT installation.
12.2.4.1 PT Router Operational Statuses
Refer to Table 12-2 below for a brief description of the possible PT charge controller operational
statuses that may display (depending on your router).
Table 12-2, PT Controller Router Operational Statuses
12.2.4.2 PT Router Relay Statuses
The following “Relay” statuses indicate whether the Aux Relay is “engaged” or “disengaged”.
Table 12-3, PT Router Relay Statuses
Status Description
Disengaged This status indicates that the PT controller is no longer energizing the Aux Relay.
When the Aux Relay status shows “ Disengage ”, the COM to N.O. contact is
open, and the COM to N.C. contact is closed.
Engaged This status indicates that the PT controller has energized the Aux Relay. When
the Aux Relay status shows “ Engage ”, the COM to N.O. contact is closed, and
the COM to N.C. contact is open.
Info: The Aux Relay can be activated manually; or activated automatically based on
battery voltage or if a PT controller fault occurs. Refer to the CTRL: 04B PT Aux Relay
Control menu to see the selection that is used to activate the Aux Relay.
