TM-2030 Installation & User Guide

Advanced Programmable Parameters
Programming Instructions for the TM-2030: http://www.bogartengineering.com/wp-content/uploads/docs/EnterP1Data.pdf
Refer to SC-2030 instructions for programmable parameters when using the SC-2030 Solar Charger (P8-P14-P15-P16-P20-P21-P22)
P8-P22 are accessible only when Program P7 is set to L3 or L4. Default values shown below are automatically installed when switching from L4 or L3 into
L2 or L1.
P9: Lo-battery audible alarm: based on % full and battery voltage. Set “low % full” alarm point with P9 (OFF, 1-100%). Default “OFF”.
P10: Efficiency factor (60-100%): This parameter affects how the “% full” is evaluated. Discharging amp-hours always evaluated at 100%. Charg-
ing amp-hours evaluate at an amps rate determined by this setting. This compensates for battery charging inefficiency. The default and recom-
mended value is 94%
P11: Shunt type: Set to “H” for 500A/50mV. Set to “L” for 100A/100mV. Default H. Also use “H” when using a 1000 A-100 mV shunt (rarely used)
P12: Auto Reset ON-OFF: When OFF percent full and amp hours are not automatically reset. Default ON
P13: Low battery voltage alarm setting: “low threshold volts” (10.0-65.0 V) Default: 10.0 Audible alarm also controlled by P9 . 
P17: Shows how many hours after “now” that daily history data H7, H8 ,H9 will be recorded: (0-24). Default 12
P18: Battery calibration voltage adj. Not recommended unless advised by Bogart Engineering.
See TM-2030 User’s Instructions, Section 6.4.
P19: Resets TriMetric to factory default settings.
