831 Series
The 831 voltage sensor is a single-phase ac voltage device that is capable of monitoring and reacting to over and under voltage conditions. This product is designed to be wired across terminals A1 and A2 with the voltage that is being monitored. The two LED lamps indicate both when the input voltage is present (green LED) and also when the output is energized (red LED). The Umax dial is used to set the upper trip-point for the voltage sensor. The Umin dial is a percentage of the Umax dial and is used to delay the transfer of the contacts, from 0 to 10 seconds, when a set point has been violated.
