accept Aux AC input, the batteries will be Bulk charged and the system will switch to inverter again.
2.4 Gen
Start
The Gen Start feature is designed for use in installations having a generator to provide Aux AC input power for
battery charging. The Gen Start feature provides a contact closure to signal the generator to start when battery
voltage falls below the ‘Gen Start Volts’ setpoint. The Gen Start contacts open when bulk charging amps fall
below the ‘Gen Stop Amps’ setpoint. Bulk charging amps are sampled every 4 minutes, therefore the minumum
generator ON time is 4 minutes. The contacts are NEC Class 2, rated 2 amps at 12 or 24 VDC.
Gen Stop Amps should be set higher than the Absorption Charge Amps setpoint.
Caution: The battery charging process will be affected if 24VDC loads are being powered during battery
charging. The increased charger output, required to power those loads, may keep the charger from reaching
the ‘Gen Stop Amps’ setpoint.
3 TSR-2 Remote Control Panel (optional)
3.1 General
Description
The TSR-2 TruSine Remote Control Panel is an optional
display/keypad module that allows the installer to adjust the
system operation factory setpoints and allows the user to
monitor and control in detail the TruSine Inverter/Charger
operation. The TSR-2 connects to the inverter at the V-NET
Port. One or more control panels may be installed to provide
the necessary level of system control and flexibility. The
TruSine Inverter/Charger System setpoints will not change
after removal of the TSR-2 Remote.
TSR-2 Control Panel
The TSR-2 TruSine Remote Control Panel contains a 32 character (two 16 character lines) liquid crystal display
(LCD), a red Alarm LED indicator, and a functional keypad. A menu scheme is used to allow the operator to
select and control system functions, and to display information. In the event of a system fault the Alarm LED will
illuminate and a fault message will be displayed. The TSR-2 Remote connects to the inverter’s V-Net Port via a
6 conductor modular data communication cable. The unit is supplied with a 25’ long cable with a 6-pin RJ-11
connector at each end.
Early production TSR-1 Remotes, used with earlier model Vanner inverter/chargers, are identical to the TSR-2
but will need the software upgraded to A88769-A to access the GenStart and other new features in the TruSine
4500 Inverter/Charger. TSR-2 software is identified in the General Information Menu step 52. TSR-1 software is
identified in System Information step 53 for theTSC24-4000D.
