Surge Counter Option

In units so equipped, the surge counter option provides a means to total the number of transient voltage surges encountered since the counter was last reset. The surge counter circuitry includes a "supercap". This will provide power up to four days to retain memory should a power outage occur. NOTE: There is a 10 - 15 minute charging cycle once power is connected, before the surge counter operates. The Surge Counter registers the sum of L-N and L- G transient surges. There are Count and Reset touchpads. Pressing the Count touchpad increments the counter by one. Pressing the Reset touchpad resets the counter to zero count.
