Oxymitter 5000
3. One contact per probe from SPS 4000
to the control room for "calibration
failed" notification, which includes out-
put from pressure switch indicating "cal
gas bottles empty".
NOTE
The fieldbus digital signal can be con-
figured to respond normally during
any calibration, or can be configured
to hold the last O
2
tiation of calibration. Factory default is
for the fieldbus signal to operate nor-
mally throughout calibration. Holding
the last O value may be useful if sev-
2
eral probes are being averaged for the
purpose of automatic control. Unless
several probes are being averaged,
always place any control loops using
the O signal into manual prior to
2
calibrating.
b. Other Electrical Connections
1. Remove screws (26, Figure 4-1) se-
curing terminal cover (27). Remove the
cover to expose terminal strip (25).

2. Connect Line Voltage. Route the line
voltage leads into the manifold through
the 1/2 in. line voltage conduit fitting
(Figure 2-2) and out through the bot-
tom of the manifold. Connect the LINE
IN and NEUTRAL leads to terminals L
and N, respectively, as shown in Figure
2-10. Also, be sure to connect the
ground wire to the ground lug. The unit
automatically will configure itself for 90
to 250 VAC line voltage and 50/60 Hz.
The power supply requires no setup.
3. 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.
