C-Series LCD Meter Displays
Two optional LCD digital meter displays are available for the C-Series
controllers; the DVM/C40 replaces the standard faceplate on the C-Series
controller and the CMR/50 or CMR/100 mounts remotely. The remote version is
available with either 50 foot or 100 foot cables. Longer runs may be possible
(up to 1000 ft/305m) because the communication is a serial-data type link.
These displays include a two-line, 32-character LCD and a status LED
indicator.
The LCD displays provide the following information:
· PV Array or DC load pass-through current: 0 to 85 amps DC
· Battery voltage: 4 to 100 volts DC
· Watts: 0 to 3600 watts (volts times amps)
· Amp-hours: 0 to 65536 Ah; can be reset to 0
· Totalizing amp-hours: 0 to 65536 Ah; resets to zero when power is
disconnected
· Status LED: green, red, or orange
If the C-Series controller is disconnected from the battery or the meter
cable, the meter will be reset when it is powered up. Press and hold the push-
button on the front of the meter to manually reset the amp-hour meter. Press and
release this button to turn the backlight on or off. An adjustable potentiometer
on the back of the meter enables you to adjust the contrast of the LCD display.
When installing the meter, be sure to set the jumper on the printed circuit board
over the pin set to match the controller board for the system voltage, either 12,
24, or 48 volts.
