that the pins line up with the socket holes. Then press in firmly. Proceed further for
important information about where to plug each style of relay:
a. If you are using only standard relays in your programmable cam (not optional solid
state relays), they are plugged into channels 1 through 8 — slots labeled K301
through K305, K307, K309, and K311 (see Figure 2 - 23).
b. If you plan to use solid state relays, then they can only be plugged into channels 5
through 8 only — slots labeled K306, K308, K310, and K312.
c. Do not plug both standard and solid state relays in the same channel locations for 5
through 8. For example, if you plug a solid state relay into channel 5 (location
"K306"), you cannot plug a standard relay into location "K305." See Figure 2 - 23.
d. As an example, say you wish to use three standard relays and one solid state. You
would install the three standard relays in channels 1 through 3, and the solid state
relay in channel 5 on the cam outputs board assembly. Then you must skip
SmartPAC 2's channel 4 output for all wiring and programming, and instead use
channel 5 for all wiring and programming.
4. Find the 12-conductor cables that run from the SmartPAC 2 ProCam 16 PC board (see
Figure 2 - 41 for an illustration of the board) to the terminal blocks marked TB301 inside
the ProCam output enclosure. Notice that there are two cables: one for 1 through 8, and
another for 9 through 16.
5. Attach one end of the cable to the connector for TB451 for channels 1-8. Note that
TB452 on the 16-channel board is for channels 9-16. Refer to the Table 2 - 5 and Table
2 - 6 later in this section for proper wiring. If you have an 8-cam board only then
connect channels 1-8 to TB401.
6. Run the cable through conduit to TB301 in the ProCam output enclosure. You can use
the knockouts directly below the connectors on each enclosure.
7. Attach the other end of the cable to the connector for TB301. A wire from CHAS to a
lug on the ProCam output enclosure should already be connected (unless you bought the
board assembly only).
8. Plug cable connectors into their sockets.
9. To connect the relays to your equipment, use connector TB302 and TB303. See Figure
2 - 24
How you make connections depends on the type of relay you use. For 120 VAC relays you
can connect wires from your equipment to "C" and either the N/O or N/C side of the relay. If
you connect to N/O, the equipment will be on for the degrees set on SmartPAC 2. If you
connect to N/Ç the equipment will be on except for the degrees set. Generally, you use the
N/O terminal; so equipment is off except when you use SmartPAC 2 to turn it on. Use the
N/C terminal only if it is more practical to do the reverse.
All solid state relays work only when the C and the N/O side is connected. Polarity must be
right for some relays — refer to Table 2 - 7, page 88.
