Figure 11 Jumpers The C-Series controllers are equipped with several of these jumpers. The factory default settings are shown below.

When AUTO is enabled in Load Control mode, the unit will reconnect automatically when voltage at the BATTERY POSITIVE terminal exceeds the LVR setting. Factory setting is manual equalization and manual reconnect. 12 Volt Position 24 Volt Position 48 Volt Position C40 C35 and C60 12 Volt Position 24 Volt Position Figure 13 Voltage Selection Jumper Operating Mode This jumper determines the operating mode: PV Charge Control and Diversion Control mode, or Load Control mode. Factory setting is Charge Control mode. Figure 14 Operating Mode Jumper Reset Switch Press and hold to manually initiate or suspend battery equalization in Charge Control mode. Press and release to reconnect following a low-voltage disconnect event. If voltage remains below the LVD setting, the unit will disconnect after a 6-minute grace period. Figure 15 Reset Switch Jumper ©2000 Xantrex Technology Inc. 25 3. 0 INSTALLATION Voltage This jumper determines the voltage of the system that the controller will be used with. Connect the two pins adjacent to the legend for the voltage of your system: 12, 24, 48. The maximum DC voltage allowed is 125 VDC for a C40, and 55 VDC for the C35 and C60. If the optional LCD meter (DVM/C40 or CM/R) is attached to the C-Series controller, be sure to set the jumper on the back of it for the appropriate system voltage. The jumper for limiting power consumption and dimming the CM display is also located on the back of the LCD Displays. 12 Volt Position 24 Volt Position 48 Volt Position C40 C35 and C60 12 Volt Position 24 Volt Position Figure 16 Voltage Selection Jumper 26 ©2000 Xantrex Technology Inc. 3. 0 INSTALLATION Adjusting the C-Series The charging rate and voltage reconnect/disconnect setting of the controller are adjustable via two rotary potentiometer controls. The knobs are removable to reduce the likelihood of tampering with the settings. Calibrated scales are provided to allow setting of the control without requiring the use of a digital voltmeter. Visual adjustment allows an accuracy of ± 0. 1 volts. Setting Voltage Parameters In Charge Control mode, you can adjust the bulk and float charging voltage by adjusting the potentiometers (pots) located in the bottom center of the controllers circuit board (for more information regarding bulk and float charging rates, see the Three-Stage Battery Charging Process section of this manual). The potentiometer scale for bulk charge voltage is calibrated from 13. 0 to 15. 0 volts (when the voltage jumper is set for a 12 volt system) in increments of 0. 2 volts, from 26. 0 to 30. 0 volts (24 volt system) in increments of 0. 4 volts, or from 52. 0 to 60. 0 volts (48 volt system) in increments of 0. 8 volts. For float charge voltage, the potentiometer scale is calibrated from 12. 5 to 14. 5 volts (12 volt system), 25. 0 to 29. 0 volts (24 volt system), and from 50. 0 to 58. 0 volts (48 volt system) with the same increments as above. Charge/Diversion Control Mode Figure 17 BULK and FLOAT Voltage Adjustment Potentiometers ©2000 Xantrex Technology Inc. 27 3. 0 INSTALLATION Testpoints for Voltage Settings At midrange on these scales, a testpoint is provided for use with a DC digital voltmeter for assuring more accurate adjustment. The pots are equipped with removable knobs to prevent accidental adjustments by the curious or uninformed. If the knobs are missing, a 5/64" hex-head driver can be used to adjust the settings. A digital voltmeter can be connected from the COMMON NEGATIVE terminal on the circuit board and the small testpoint located to the left of each adjustment pot at the nine oclock position. The testpoint provides a reading from 0 to 2 volts; this value must be added to the lower value of the adjustment range (Bulk=13. 0, Float=12. 5, LVR=12. 0, LVD=10. 5). [. . . ] It is not recommended that light bulbs be used as diversion loads for a couple of reasons: 1. An incandescent light bulb has a substantially lower cold filament resistance than when it is on. This means it draws more power (up to five times) to start the light when it is cold than once the filament has warmed up. Even a 40-watt light bulb may have an in-rush amperage at turn-on of 200 amps. [. . . ]
