3.1.4 Switched Auxiliary Output (AUXSW+ and AUXSW–)

The AUXSW+ and AUXSW– terminals on the 12 volt dc Power Input module (PM-12) provide switched power for external devices, such as radios. AUXSW+ is current-limited for protection of the power input and the external device via a 0.5 Amp nominal Positive Temperature Coefficient (PTC). The AUXSW+ and AUXSW– terminals provide voltages from 0 to 14.25 Volts dc. AUXSW+ is turned off when the ROC827 detects a software configurable voltage (LoLo Alarm) at the BAT+ and BAT– terminals. All module terminal blocks accept 12 AWG or smaller wiring. Refer to Figure 3-3.

If the source voltage falls to a level below which reliable operation cannot be ensured, the hardware circuitry on the Power Input module automatically disables the AUXSW+ outputs. This activity occurs at approximately 8.85 Volts dc, and is based on the LoLo Alarm limit set for the System Battery Analog Input Point Number 1. The low input voltage detect circuit includes approximately 0.75 Volts dc of hysteresis between turn-off and turn-on levels.

The presence of high input voltage can damage the linear regulator. If the dc input voltage at BAT+ exceeds 16 volts, the over-voltage detect circuit automatically disables the linear regulator, shutting off the unit. For further information on the STATUS LED functions, refer to Table 2-2in Chapter 2, Installation and Use.
