The Incremental Mode time increase follows the formula of:
𝐼𝑛𝑐𝑟𝑒𝑚𝑒𝑛𝑡𝑎𝑙 𝑆𝑙𝑒𝑒𝑝 𝑇𝑖𝑚𝑒 = 𝐼𝑛𝑖𝑡𝑖𝑎𝑙 𝐷𝑒𝑙𝑎𝑦 × 1.5
𝑥
Where
𝑥
is the number of times the PF1 has consecutively entered a sleep state. The
𝑥
count is
capped at 4 which represents a time period of roughly 5 times the initial delay. After the PF1 has
entered sleep mode four consecutive times, the sleep time will no longer increase and will remain
constant at that duration.
The PF1 is considered to have entered sleep mode consecutively if, after waking up from a sleep state,
the pump operates for the defined period and does not exceed the specified undercurrent level. After
an adjustable initial time period has passed, the PF1 will then initiate another sleep cycle and the
consecutive sleep count will increase.
This sleep count will reset under any of the following conditions:
a) The under-current level is exceeded
b) The pump is stopped / tripped
c) The pump is started with the start button
d) The PF1 loses auxiliary power
