Oxymitter 4000

f.Connect Remote Contact Input Wiring

To set up the SPS 4000 to initiate a calibra- tion from a remote location, route the 5 VDC calibration initiate contact input leads through the 1/2 in. NPT signal conduit port (Figure 2-2)and out through the bottom of the manifold. Connect the (+) and (-) CAL INITIATE leads to terminals 1 and 2, re- spectively, as shown in Figure 2-10.

g.Connect Relay Output Wiring

Relay connections are available to signal when the Oxymitter 4000 is in calibration or when calibration failed. Relay outputs can be connected to either indicator lights or a computer interface. The relay contacts are capable of handling a 5 to 30 VDC maxi- mum power source.

The cabling requirement is 1000 ft (303 m) maximum. Route the relay output leads through the 1/2 in. NPT signal conduit port (Figure 2-2)and out through the bottom of the manifold. Connect the (+) and (-) CAL FAIL leads and the (+) and (-) IN CAL leads to terminals 7, 8, 9, and 10, respectively, as shown in Figure 2-10.

h.Connect 4-20 mA Signal Wiring

Route the 4-20 mA signal wiring into the manifold through the 1/2 in. NPT signal conduit port (Figure 2-2)and out through the bottom of the manifold. Connect the (+) and (-) signal leads to terminals 3 and 4, re- spectively, as shown in Figure 2-10.

i.Once all connections are made, install ter- minal cover (27, Figure 6-11)and secure with screws (26).
