All
Hydro-Eye Monitor
probes need approximately 6 volts to operate. Thus
on a standard 6 volt battery like an L-16 or T-105
the probe is inserted into the acid in the center
cell and the black wire is connected to the battery
negative terminal and the red wire to the battery
positive terminal.
On
an industrial battery with lead straps
connecting the cells in series, the Monitor probe
is inserted into the acid in a center cell and the
black wire is connected to the outboard strap on the
adjacent cell towards the battery negative post. The
red wire is connected to the outboard strap of the
cell on the opposite side.Thus there is approximately
6 volts between the wires.
On
an 8D battery the red and black wires
connect directly to the battery terminals. A voltage
regulator in the probe permits 12 VDC operation.
On
a Group24 or Group27 battery the
probe is inserted into the middle cell of the cover
next to the battery negative post and the short black
wire connected to the negative post and the longer
red wire connected to the positive post. A 1/8"
diameter hole must be drilled through the cell cover
for the probe.
All
Hydro-Eye Alert, Alarm and Combo
probes also require 6 volts to operate. On an industrial
battery the black wire is connected to the outboard
strap on the cell adjacent to the cell being probed
in the direction of the battery negative terminal
and the red wire from the probe connected to the outboard
strap of the cell on the opposite side. Thus there
is 6 vdc between the red and the black wires with
the probe in the middle. On a standard 6 volt battery
the red and black leads connect to the battery terminals
with the probe in the center cell.
The
G24 and G27 Marine batteries
are all 12 volts and there are no inter-cell straps
to connect to so Hydro-Eye includes a voltage regulator
into the Alert, Alarm and Combo probes for these batteries
which will allow 12 volt operation.
