Figure 2-8. Installing the LMCS and magnets
4. Once the LMCS is installed, you are ready to wire it to the connector for TB1. Open
the AutoSet cover and find connector TB1 at the left center of the box. See Figure 2-9.
Black wire goes to terminal 5 (gnd); white or clear goes to terminal 2 (zero cam); red
goes to terminal 4 (sensor power).
5. Run wires from the cam switch through flexible, liquid-tight conduit to the bottom left
knockout on box. The control box is rated NEMA 12 (protected against dust and oil).
Therefore, you must use conduit rated NEMA 12 and make proper conduit connections
to ensure NEMA 12 protection.
6. Pull connector out of socket. How you wire the switch depends on the type used.
The LMCS will require power. Some other switches are mechanical so you do
not need to apply power to the switch. If you are using a programmable limit
switch (PLS) to supply the zeroing signal, you will not need power for the switch
either. See below for more information.
a. If your switch needs power, make connections to the terminals 12
Vdc (pin 4) and GND (pin 5). See the instructions for your switch to make
proper connections.
b. For all switches, connect the zero cam circuit by connecting the switch to the
terminals ZERO CAM (pin 2) and GND (pin 5).
c. Connections are made in the same way as for AC power and strain link
connections (see "Mounting and connecting strain links" and "Connecting AC
wires to power source" in this chapter). Make sure you did not get wiring
backwards due to turning connector the wrong way once removed from
socket.
