TABLE 2-2. TB1 INPUT/OUTPUT TERMINAL ASSIGNMENTS
TERMINAL NO.
NAME
DESCRIPTION OR FUNCTION
1
Control
With a jumper between these terminals and the battery connected, the TBC Con-
trol Board will remain ON even if the AC Circuit Breaker is OFF. With the jumper
removed the Control Board will go OFF if the AC Circuit Breaker is OFF.
2
ON/OFF
3
Meter (+)
This terminal provides an outside contact point from the positive side of the LCD
voltmeter for remote monitoring of the output voltage.
4
+S
(Sense)
This terminal is the positive Remote Sensing terminal for the TBC output voltage.
5
+M
(Monitor)
This terminal is connected to the positive output terminal of the TBC Battery Char-
ger and is used for Local Sensing.
6
–M
(Monitor)
This terminal is connected to the negative output terminal of the TBC Battery
Charger and is used for Local Sensing.
7
–S
(Sense)
This terminal is the negative Remote Sensing terminal for the TBC output voltage.
8
Meter (–)
This terminal provides an outside contact point from the negative side of the LCD
voltmeter for remote monitoring of the output voltage.
9
CB
(Current Balance)
This terminal is used when two or three TBC units (except for the TBC 12-20M,
which doesn't require Current Balance) are connected in parallel (consult the fac-
tory for details).
10
Common
This terminal is logic ground.

TERMINAL NO.
NAME
DESCRIPTION OR FUNCTION
1
+RC
(Remote Control)
Remote Control ON/OFF Input Command. An open (logic high) between the +RC
and -RC terminals will turn OFF the TBC. A short circuit (or logic low) between
these two terminals will return the TBC to operation. Logic high is between 2.4V
and 24V d-c; logic low is between 0V and 0.4V d-c. When high, this terminal can
sink 1.0 rnA maximum; when low this terminal can source 1.6rnA maximum.
2
–RC
(Remote Control)
3
Power On
Power On Output Flag. A logic high at this terminal (with respect to Common)
indicates that AC input power is ON. A logic low indicates that AC input power is
OFF.
4
Charging Stopped
Charging Stopped Output Flag. A logic low at this terminal (with respect to Com-
mon) indicates that the battery voltage is equal to or greater than the Power Sup-
ply voltage and that the battery has been charged. A logic high indicates that the
Power Supply voltage is higher than the battery voltage and that the battery is
being charged
5
Float/Equalize
Float/Equalize Output Flag. A logic high at this terminal indicates that the TBC is
in the Float (low charging rate) mode. A logic low at this terminal with respect to
Common indicates that the TBC is in the Equalize (high charging rate) mode.
6
Start
Start Input Command. A short circuit condition (provided by a computer low signal
or momentarily closing a switch) at this terminal with respect to Common starts
the TBC timer and the TBC goes into the Equalize mode.
7
+5 Volts
+5 Volts d-c
8
Reset
A short circuit condition (provided by a computer low signal or momentarily clos-
ing a switch) at this terminal with respect to Common resets the Equalize Timer
and the TBC goes back to the Float mode.
9
50/60Hz
A jumper between this terminal and Common sets up the TBC for 60Hz input
power operation. With jumper removed the TBC is set for 50Hz input power oper-
ation.
10
Common
This terminal is logic ground.
