57. BATTERY START AMPS
(Opportunity/Fast charging without a BID)
Programs the charger start
rate at the programmed
charger AH setting to the
selected amps/100AH. For
example, to charge an 800AH
battery at 320 amps, the
“battery start amps” would be
programmed to 40A/100AH.
Please note that if the pro-
grammed rate exceeds the
maximum rated charger amps,
the charger output will be
limited to the maximum current
rating.
58. BID START AMPS
(Opportunity/Fast charging with a BID)
Programs the charger start
rate at the programmed BID
AH setting to the selected
amps/100AH. For example,
to charge an 800AH battery
at 320 amps, the “bid start
amps” would be programmed
to 40A/100AH.
Please note
that if the programmed rate
exceeds the maximum rated
charger amps, the charger
output will be limited to the
maximum current rating.
59. MAX CHARGE The maximum battery
TEMP temperature for charging to
proceed.
(080 to 150 degrees F)
Factory setting = 150
Using extended AH for Opportunity/Fast
charging on the Power Star Plus.
The Extended AH feature of the Power Star Plus allows
the user to Opportunity/Fast Charge batteries at charge
rates from 20-50A/100AH, as long as the actual charge
current is within the name-plate rating of the charger.
Batteries that are rated below the maximum AH rating
of the charger can be Opportunity/Fast charged at
Rates higher than the normal 25A/100AH.
Using a BID
When a BID is installed on the battery, it must have the
“Battery Start Amps” set to a value between 20 and 50.
The charger will then supply a start current equal to the
battery that is programmed into the bid divided by 100.
See the example below:
Battery 24 cell, 600AH (24-100-13)
Charger 1045Z3-24PF
BID settings:
BID cells 24 (Function 52)
BID AH 0600 (Function 54)
BID Battery Type 08 (Function 55)
BID Start Amps 40 (Function 58)
Resulting Charge Rate:
Start Amps — 6 x 40 = 240 Amps
Finish Amps — 4.5 x 6 = 27 Amps
Charger rated start amp = 261
Not using a BID
The example below describes how to accomplish ex-
tended amp-hour charging without the use of BID
Module on the battery.
Battery 24 cell, 600AH (24-100-13)
Charger 1045Z3-24PF
Charger settings:
Charger Fixed AH 0600 (Function 37)
Charger Curve Type 08 (Function 39)
Battery Start Amps 40 (Function 57)
Resulting Charge Rate:
Start Amps — 6 x 40 = 240 Amps
Finish Amps — 4.5 x 6 = 27 Amps
Charger rated start amp = 261
*Note: In order to use any of the opportunity/fast
charge modes of this control, it must be in
“plus” mode. “” should appear
on the display. To put the control into
“plus” mode, hold the 2 and 5 keys down
while applying AC power. The control is
put into standard mode by holding the
1 and 6 keys while applying AC power.
