Introduction
The components provided in this kit enable the station output capacity of the Network LTC Plus satellite to be increased beyond
32 stations. Installation of the additional distribution PCBA (printed circuit board assembly) enables up to four 8-station output
modules to be installed, increasing station output capacity to 64.
The kit includes the following components:
• (1 ea.) Distribution PCBA with 24V detect circuit, P/N 89-9316
• (1 ea.) Distribution Board Insulator, P/N 89-9413
• (1 ea.) 16-Pin to16-Pin Ribbon Cable Assembly, P/N 89-8692
• (1 ea.) 4-Wire Cable Assembly, P/N 89-8696
• (3 ea.) # 6 x 1/2" Tap Screws, P/N 363-1355
Note: The expansion kit does not include the 8-station output module(s) optional 8-station terminal strip, or optional
16-output surge modules required for the connection of additional irrigation control valves. These components must be
purchased separately from a Toro distributor. However, the following instructions provide the installation procedures for
these components since they are generally installed with the distribution PCBA kit.
Procedure
1. Remove both cabinet doors. Place the satellite power supply
switch in the Off ( I ) position.
Note: The function of the 24V detect PCBA (shown in
Figure 1) is now incorporated into the new distribution
PCBA. Therefore, the 24V detect PCBA is no longer
required and should be removed prior to installing the
distribution PCBA included in this kit.
The 24V detect PCBA is an optional component and may
not be installed in the satellite. Procedural steps 2 through
5 cover the removal of this component. If the satellite
does not have the 24V detect component, disregard steps
2 through 5 and continue at step 6.
2. Locate the 24V detect PCBA and remove all of the attached
cables (A, B, C & D).
3. Remove the single #6 tap screw used to secure the 24V detect
PCBA to the chassis. Carefully lift the 24V detect PCBA upwards,
unplugging it from the distribution PCBA socket.
4. Plug the ribbon cable connector (B) into socket (BB).
Note: The ribbon cable connector (B) is not keyed and can
be installed incorrectly. The blue orientation stripe on the ribbon
cable must be on the left side (when facing the cable/socket).
5. Plug the 2-wire (black and white) connector (D) into
socket (DD).
6. Working now on the back of the black plastic chassis, position
the new distribution PCBA onto the chassis, guiding the PCBA
onto the 5 plastic bosses as shown in Figure 2. Secure with
two #6 screws installed in the center and left side screw hole
locations.
7. Install the insulator card over the bottom portion of the distribution
PCBA. Use the two outside plastic bosses to guide the card
into position. Secure the card with a #6 screw installed in the
right side screw hole location. See Figure 2.
