TERMINAL BOX WIRING INSTRUCTIONS
(OPTIONAL)
The terminal box offers a simple way to locate the solenoid
signal wires. Typically used when an existing system is removed,
their signals can be brought to this box and terminated with the
Aqua-Lab.
INSTALLATION INSTRUCTIONS
1.
Determine location and hang terminal box. Note that the side of
the box with three holes is for the Aqua-Lab control cables (yellow
cables), and the side of the box with 5 holes is for the incoming
activation signals from the wash controller. Orientate box accordingly
and within reach of Aqua-Lab yellow cables
2.
Remove Cover and notice the labeling of the terminals (Figure 2).
Each chemical bank of the Aqua-Lab is labeled as 1, 2, & 3. For TX
model this corresponds to top (1), middle (2), and bottom (3). For AX
model this corresponds to left (1) and right (2)
3.
Bring the yellow cable from the corresponding chemical bank to the
box and insert through cable gland as shown. (Figure 3)
4.
Using a small screwdriver, press into the spring terminal and pull
away from the wire terminal to open the spring clamps. Insert the
wire that corresponds to the labeled color then release the spring by
removing the screw driver (Figure 4)
5. Repeat for all colors labeled. (brown and red are not used)
6. Blue and Green/Yellow are to be wired to the common and ground
terminals which are segmented as shown (Figure 5)
7.
Repeat for all yellow Aqua-Lab cables
8. Individually insert chemical activation signals through cable glands
and wire to desired chemical position (see wiring chart in operations
manual) (Figure 6).
9.
Repeat for all chemical signals, only one of the common (blue) and
ground (Green/yellow) wires for the signals need to be wired to the
corresponding segmented terminals since they should be previously
connected at the wash controller. You can wire up to three of the
commons and grounds to ensure a redundant connection.
10.
Lightly tug on all wires to ensure a good connection.
11.
