In the Absorb Time Limits screen, the user can set the
minimum and maximum times the MX60 stays in the
Absorb recharge cycle.
MAXimum is adjustable from 0 to 4 hours.
MINimum is adjustable from 0 minutes (the
default) up to the maximum absorb time limit
minus 10 minutes. (EX: Maximum Absorb time =
2 hours or 120 minutes Minimum Absorb time
adjusted up to 110 minutes)
To adjust the limits, press either the <MIN+> or
<MAX+> soft key. When nished, press the <NEXT>
soft key to view the next screen.

Bulk cycle begins Absorb charge is reached At zero, MX60 goes into FLOAT
Timer starts Timer begins counting to zero
NOTE: In BULK, the MX60 will charge as long as necessary to complete the cycle, regardless of the
timer’s set points.
• A Bulk cycle starts each morning. The charge timer (ChgT) is preset to the minimum Absorb time
limit (zero minutes) while the Bulk/Absorb Charge Timer counts up in minutes.
•
The timer stops when it reaches the Maximum Absorb Time or the Absorb voltage set point is met.
• The ChgT counts down to zero after the Absorb voltage is reached.
• At zero, the MX60 goes into Float stage and may brie y display “Bat Full” (Battery Full) then “Float.”
• When the battery voltage drops below the oat voltage set point, the MX60 recharges to main-
tain this set point, employing the F(Float)-MPPT function.
• If the system cannot maintain the Absorb voltage set point during the Absorb cycle, the timer
will stop counting down and begin counting up towards the Max Absorb time as the MX60
transitions to Bulk (BMPPT). This up and down counting will continue until the charge timer counts
down to zero. The Absorb cycle can be disabled by setting the maximum to 0hr.
