TB3
The input terminals are located on TB3 of the 3528C2 or 3528C3 board. They
can use an internal supply with a dry contact or an external 24VDC.
4.3.1.1.
24V+ S
UPPLY
- TB3-1, TB3-3
The internal supply is capable of supplying 50mA at 24VDC. It is intended
to be used for the inputs of the M3528 locally, and should not be used as
any other source. There is not sufficient power to serve as signaling for the
output terminals.
If more power is required, the inputs can be driven from a separate 24VDC
power source. When a separate power source is used, the negative or
common of that power supply should be connected to TB3-5.
4.3.1.2.
E
NABLE
I
NPUT
- TB3-2
The enable input allows the M3528 charger module to charge the storage
bank. 24VDC may be placed between TB3-2 and TB3-5 or a contact closed
between TB3-1 and TB3-2 to enable the charger module.
4.3.1.3.
E
QUALIZE
I
NPUT
- TB3-4
The equalize input allows the M3528 charger module to enter equalize
mode and charge to the equalize voltage setting. 24VDC may be placed
between TB3-4 and TB3-5 or a contact closed between TB3-3 and TB3-4
to put the charger into equalize mode.
Both the Enable Input and the Equalize Input must be activated for the
charger to operate in Equalize mode.
4.3.1.4.

NPUT
C
OMMON
- TB3-5
This terminal is the common for the inputs only. If the internal power supply
from TB3-1 is used, there is no connection to this terminal.
This common is not connected to ground, and should not be connected
locally to avoid noise in the control circuits or ground loops.
It is also separate from the output common to allow the use of separate
power supplies if desired.

TB4
The status of the M3528 can be monitored from TB4 on the 3528C2 or 3528C3
board. The status outputs can be configured with jumpers to be normally open
(NO) or normally closed (NC). In the descriptions below, the operation is
described for the jumpers to be set in the normally open position, which is the
default setting.
4.3.2.1.
O
UTPUT
C
OMMON
- TB4-1
This pin is common to both the Charging and Ready outputs.
This common is not connected to ground, and should not be connected
locally to avoid noise in the control circuits or ground loops.
4.3.2.2.
C
HARGING
O
UTPUT
- TB4-2
This output closes to the output common at TB4-1 when the M3528 is
currently supplying current to the attached storage bank.
The output configuration can be set to normally open or normally closed
with Jumper J2 on the 3528C2 board or J6 on the 3528C3 board.
