ELECTRICAL CONNECTIONS

All wiring must conform to local and national
codes. Use the following procedure to connect
an SPS 4000 to an Oxymitter 4000.
Disconnect and lock out power before
connecting the unit to the power
supply.
NOTE
Ensure the Oxymitter 4000 is set up to
handshake with the sequencer by con-
figuring the logic I/O to mode 8. Refer
to the Oxymitter 4000 Oxygen Trans-
mitter Instruction Bulletin for more in-
formation.
a. Remove screws (20, Figure 4-1) securing
terminal cover (19) and remove the cover.
b. Route the line voltage leads into the mani-
fold through the lower 1/2 in. conduit fitting
on the right side of the manifold (Figure 2-1)
and out through the bottom of the manifold.
Connect the incoming 90 to 250 VAC, 50/60
Hz line voltage leads to the terminal strip as
indicated in Figure 2-2.
c. Route the handshake logic I/O wires
through one of the 1/2 in. NPT conduit ports

on the manifold (Figure 2-1) and out
through the bottom of the manifold. Connect
the 5V (5 mA maximum) logic I/O leads
from the Oxymitter 4000 to the terminal strip
as indicated in Figure 2-2.
d. To set up the SPS 4000 to initiate a calibra-
tion from a remote location, route the 5 VDC
calibration initiate contact input through one
of the 1/2 in. NPT conduit ports on the
manifold (Figure 2-1) and out through the
bottom of the manifold. Connect the input
leads to the terminal strip as shown in
Figure 2-2.
e. Relay output connections are available on
the unit 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 wires
through one of the 1/2 in. NPT conduit ports
on the manifold (Figure 2-1) and out
through the bottom of the manifold. Connect
the relay output wires to the terminal strip
as shown in Figure 2-2.
f. Once all connections are made, install ter-
minal cover (19, Figure 4-1) and secure with
screws (20).
