Over load in discharge protection: Refer table 2.8.1.

Trip - Action : Increments AOLDL counter.

Latch Alert - Action - Decrements AOLDL counter.

please clarify when AOLDL increments and when Decrements . Both increment and Decrement statement is confusing

Hi Venkatramani,

Could you post what device you are referring to?

Hi Venkatramani,

You have a counter decrement time, a recovery time and a latch counter in the gauge. When an AOLD trips it increments the latch count by 1, if the condition persists the gauge will wait the recovery time and then the AOLD will trip again incrementing the latch count by 1. The counter dec time when it expires decrements the latch count by 1 until it's 0 or the AOLD latch count is reached.

If Latch AOLD = 4, recovery time 25s and Counter dec time = 100s the gauge will Latch AOLD after 75s (count = 4)

If Latch AOLD = 4, recovery time 25s and Counter dec time = 60s the gauge will Latch AOLD after 100s (count = 4)

If Latch AOLD = 4, recovery time 25s and Counter dec time = 45s the gauge will Latch AOLD after 125s (count = 4)

[increments] = 125s / 25s + 1 = 6, [decrements] = 125s / 45s = 2; note time counters starts after first AOLD trip (latch count = 1)
