ON/OFF switch, and a respective power LED. It also has two built-in alarm circuits with separate red LED’s for low DC voltage alarm and for system alarm monitoring. In addition, Model AC300WR also has an RS485/RS422 interface at the bank panel for low DC power alarm and for system alarm remote monitoring. -

Page 10: Power Requirements
The Model AC300WR Redundant Power Supply/System Monitor operates with either a 115VAC or 230VAC power sources. The unit automatically recognizes the input voltage. There is no switch for 115VAC or 230VAC, hence making Model AC300WR a completely universal input AC-voltage power supply. -

DB-25 female RS485/RS422 interface on the back panel of the unit. The location of the connector is shown in Figure 4. The Model AC300WR alarm circuitry monitors all alarms set by each circuit card and will therefore change state and oscillate whenever there is a loss of sync (such as due to a possible failure of fiber) on a FOM II card. - Page 12 Voltage Voltage Note Output DC voltage reduction level is reciprocal to the output frequency at the RS484/RS422 interface. As the voltage decreases from about 10V to Threshold Voltage (due to overload), the frequency respectively increases from 0Hz to 4.9Hz. www.versitron.com...

Page 13: Redundant Power Configurations
This is accomplished by supplying separate power sources to the two independent AC INLETS of the Model AC300WR unit and turning ON both AC POWER switches located on the front panel. By doing this the unit will supply a combined total power of 600 Watts to the system. -
Page 14: Section 4: Theory Of Operation
INTRODUCTION The second generation VERSITRON fiber optic modem and interface extender products, the FOM II Series, are designed to operate with 12 VDC input power. The Model AC300WR Redundant Power Supply/System Monitor has been developed to provide adequate power for up to 20 FOM II modems in a Model HF-20A chassis. -

LEDs are ON but the other status indicators are not correct, first check that the 12-pin power connector from the AC300WR is fully connected to the HF-20A, i.e. the DC power cord is fully inserted into the round plug and secure.
