USING THE RPS-1in the OM-420

An integral State-of-Charge (SOC) indicator is provided which will display an approximate Battery State-of- Charge based on battery voltage under a fixed load. Test is actuated by depressing a momentary SOC Test Switch.

HARDWARE / USER CONTROLS:

Figure 1 illustrates the functional blocks contained within the RPS-1. An explanation of each block follows:

MAIN POWER SWITCH

Provides ON/OFF control of the RPS-1. In the OFF position, the batteries are disconnected from the RPS- 1 circuits (power supplies, State-of-Charge indicator, charging circuits, etc.). This switch in either 12 VDC or 24 VDC ON position selects how the two 12 volt gel-cell batteries are connected (parallel for 12 VDC nominal output or series for 24 VDC nominal output). Note: For charging, the Main Power switch must be in either the 12VDC or 24VDC position.

CHARGER INPUT

Two terminal connections are provided for connection of an external current source for charging the RPS-1 batteries.

POWER SUPPLY OUTPUTS

Two independent User programmable voltage power supply outputs (A and B) feed the twelve position terminal strip on the right side of the unit. The top four terminals are all connected to the A supply output and the middle four to the B supply output. The bottom four terminals are all connected together and to the COMMON (circuit ground) of the two supplies.

OUTPUT VOLTAGE / MODE SWITCHES

Each of the two power supplies has an eight position DIP switch associated with it. The top seven switches determine the output voltage for that supply and the last switch (#8) defines the mode of operation (AUTO or ON) for the power supply.
