Battery Charger Terminology
This explanation of terms will assist in understanding battery charger operation.

Definition
3-Stage Charging/
Single Stage Charging
By setting the Bulk Mode and Float Mode to different values, the IMC Series
™
will ef-
fectively do 3-stage charging. If Single Stage Charging is desired, set the Bulk and
Float Mode settings to the same voltage level.
Bulk Duration
The time the system is in Bulk Mode. With NiCAD batteries this is called Equalize
Duration.
Bulk Mode
The higher output voltage setting for rapidly charging discharged batteries. This is also
called the Equalize Mode when using NiCAD batteries.
Equalize Cycle
(Lead Acid & NiCAD
batteries only)
When set, this is the number of days between Equalization. Lead Acid and NiCAD
have two different operations. When using Lead Acid batteries, the voltage is raised to
15.5 VDC [12 Volt mode] or 31.0 [24 Volt mode] for 1 hour to equalize the batteries.
When using NiCAD batteries, the IMC Series
™
will set the output voltage to the setting
of the Equalize Mode [Bulk Mode] for the duration specified by the Equalize Duration
[Bulk Duration].
Float Mode
The lower output voltage setting for maintaining batteries once the battery is charged.
Soft Touch Button Setting
Simply lightly touch the button with your finger. The charger will sense your finger. Pressing hard on the button is
not desirable. Remove finger from button completely before pressing next button. Avoid laying your finger from
the button to the metal housing as this may cause the button not to sense your finger properly.
Turning the IMC Series
E
ON/OFF
Press and hold the ON or OFF button for approximately 3 seconds to turn on/off the IMC Series
™
.
Note:
If the charger was left in the “ON” state, the charger will restart to the “ON” state when AC Input Power is
applied. The same holds true for the “OFF” state. If the charger was left in the “OFF” state, it will restart
in the “OFF” state when AC Input Power is applied.
Setup Mode
Setup mode allows the user to select and customize as necessary the parameters of the IMC Series
™
. All setup
mode operations are available using the following buttons:
