Oxymitter 4000
2-2 ELECTRICAL INSTALLATION (FOR
OXYMITTER 4000 WITH INTEGRAL
ELECTRONICS, WITHOUT SPS 4000)
All wiring must conform to local and national
codes.
Disconnect and lock out power before
connecting the power supply.
Install all protective covers and safety
ground leads after installation. 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 (32, Figure 9-3), gasket (33),
and cover lock (34). Remove cover (27).
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 2-10). The Oxymitter 4000
automatically will configure itself for 90-250
VAC line voltage and 50/60 Hz. The power
supply requires no setup.
c. Connect 4-20 mA Signal and Calibration
Handshake/Logic I/O Leads
1. 4-20 mA Signal. The 4-20 mA signal
represents the O
2
value and can also
operate the Model 751 Remote Pow-
ered Loop LCD Display or any other
loop powered display. Superimposed
on the 4-20 mA signal is HART infor-
mation that is accessible through a
Model 275/375 Handheld Communi-
cator or AMS software.
2. Calibration Handshake/Logic I/O. The
output can either be an alarm or pro-
vide the handshaking to interface with
an IMPS 4000. For more information,
refer to paragraph 4-2 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 8-1. The assign-
ment of alarms which can actuate this
contact can be modified to one of
seven additional groupings listed in
Table 3-1 and Table 4-1.
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 &
Brumfield R10S-E1Y1-J1.0K 3.2 mA
DC or an equal interposing relay will be
mounted where the contact wires ter-
minate in the control/relay room.
d. Install cover (27, Figure 9-3). Secure with
cover lock (34), gasket (33), and screw (32).
