Operation

Fast Blinking Orange

When the over-current or over-temperature protection system has caused the controller to shutdown, the status LED will be orange and will blink fast (about once a second).

Low-voltage Disconnect Condition

If voltage remains below the LVD setting, the unit will disconnect after a 6-minute “delay” (or “grace”) period. To reset and reconnect for another “grace” period (approximately 6 minutes), press and release the reset switch.

The user can press the reset switch for a maximum 10-minute “grace” period, or can wait until the voltage rises above the Low Voltage Reconnect (LVR) setting to allow an automatic reset to occur if the EQ/LVR (Auto) jumper is set to “AUTO”.

Slow Blinking Orange

When the disconnect/reconnect system has been activated, the LED will slowly blink orange. The controller is in the DC Load Control mode and has disconnected the loads due to reaching the LVD setting.

Reconnecting to Loads

To reconnect the loads, press the reset button on the right side of the unit. If the voltage is below the LVR level, the DC load can be reconnected for approximately 6 minutes.

A delay up to five seconds may occur before the controller attempts to restart after pressing the reset switch.

Multiple reconnects are allowed, but the “on” time duration will vary with battery voltage. The EQUALIZE jumper allows the controller to be set for AUTO reconnect of the DC load when the voltage exceeds the LVR setting.
