3.0 Setup
Info:
It is highly suggested that you install a battery monitor if
the
DoneAmps
setting is used. If no battery monitor is installed,
the
DoneAmps
setting relies on the METER menu’s
01 INV/CHG
Meter DC:
value to determine when to transfer out of the Constant
Voltage charge mode. When a ME-BMK/ME-BMK-NS is installed,
the
DoneAmps
setting relies on the METER menu’s
03 BM: Meters
DC Amps:
value to determine when to transfer out of the Constant
Voltage charge mode. This is the most accurate DC amperage
measurement (reading from the battery monitor is accurate to
+/- .1 ADC).
Info:
When using the
DoneAmps
setting, the charger will stay in
the Constant Voltage charge mode for a minimum of two minutes—
independent of the actual
DoneAmps
setting.
Info:
If DC loads are connected directly to the batteries, it is not
recommended that you use the
DoneAmps
setting. DC loads cause
the charger to increase the amperage delivered to the battery
bank in order to charge the batteries and to run the DC loads. This
scenario could result in overcharging the batteries since the return
amps reading will be skewed by the DC loads.
□
MaxTime
–
This setting is a safety feature that ensures abnormal
conditions do not cause the charger to hold batteries at a high voltage
for a prolonged period of time. This menu sets a maximum time the
charger is allowed to operate in either the Constant Current or Constant
Voltage charge modes. If the charger reaches the
MaxTime
setting, it
will transition to the Silent charge stage.
Default:
12.0 Hrs
Range:
OFF, 0.1-25.5 Hrs
□
Recharge
– This setting determines the DC voltage set-point to
which the batteries are allowed to fall—while the charger is in the Silent
charge cycle—before the charger restarts and recharges to the
Chg
Volts
setting. This setting should be at the lowest DC volts level that
you want the batteries to fall before starting a new charge.
Default:
12.0 VDC (12v), 24.0 VDC (24v), 48.0 VDC (48v)
Range:
12.0-16.0 VDC (12v), 24.0-32.0 VDC (24v), 48.0-64.0 VDC
(48v).
* Hold
VDC
– This setting holds the battery voltage at the
Chg Volts
setting. This is for a system that requires a constant charge voltage to
be present at all times (see Figure 3-14)
