Electrical Installation (For Oxymitter 5000 Without Sps 4000) - Emerson Oxymitter 5000 Instruction Manual

Oxymitter 5000
2-2 ELECTRICAL INSTALLATION (FOR OXY-
MITTER 5000 WITHOUT SPS 4000)
All wiring must conform to local and national
codes.
Disconnect and lock out power before
connecting the unit to the power
supply.
Install all protective equipment covers
and safety ground leads after installa-
tion. Failure to install covers and
ground leads could result in serious
injury or death.
To meet the Safety Requirements of
IEC 1010 (EC requirement), and ensure
safe operation of this equipment, con-
nection to the main electrical power
supply must be made through a circuit
breaker (min 10 A) which will discon-
nect all current-carrying conductors
during a fault situation. This circuit
breaker should also include a me-
chanically operated isolating switch. If
not, then another external means of
disconnecting the supply from the
equipment should be located close by.
Circuit breakers or switches must
comply with a recognized standard
such as IEC 947.
NOTE
To maintain CE compliance, ensure a
good connection exists between the
mounting flange bolts and earth.
a. Remove screw (36, Figure 4-1), gasket (37),
and cover lock (38). Remove terminal block
cover (31).

b. Connect Line Voltage
Connect the line, or L1, wire to the L1 ter-
minal and the neutral, or L2 wire, to the N
terminal (Figure 2-9). The Oxymitter 5000
automatically will configure itself for 90-250
VAC line voltage and 50/60 Hz. The power
supply requires no setup.
c. Connect fieldbus Digital Signal and
Logic I/O/ Calibration Handshake Leads
(Figure 2-9).
1. Fieldbus Digital Signal. The fieldbus
digital signal carries the O
digital signal can also be used to com-
municate with the Oxymitter.
2. Logic I/O/Calibration Handshake. The
output can either be an alarm or pro-
vide the handshaking to interface with
an IMPS 4000. For more information,
refer to paragraph 5-3 and the IMPS
4000 Intelligent Multiprobe Test Gas
Sequencer Instruction Bulletin.
3. If autocalibration is not utilized, a
common bi-directional logic contact is
provided for any of the diagnostic
alarms listed in Table 5-1. The assign-
ment of alarms which can actuate this
contact can be modified to one of
seven additional groupings listed in
Table 3-1.
The logic contact is self-powered, +5
VDC, 340 ohm series resistance. An
interposing relay will be required if this
contact is to be utilized to annunciate a
higher voltage device, such as a light
or horn, and may also be required for
certain DCS input cards. A Potter &

DC or an equal interposing relay will be
mounted where the contact wires ter-
minate in the control/relay room.
d. Install terminal block cover (31, Figure 4-1)
and secure with cover lock (38), gasket
(37), and screw (36).
