c. Connect Remote Contact Input Wiring. To set
up the SPS 4000 to initiate a calibration 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,
respectively, as shown in Figure 2-10.
d. 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 maximum 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.
e. 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, respectively, as shown in Figure 2-10.
f.
Once all connections are made, install terminal
cover (27, Figure 6-11) and secure with screws (26).
