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, connection to the main electrical power supply must be made through a circuit breaker (min 10 A) which will disconnect all current-carrying conductors during a fault situation. This circuit breaker should also include a mechanically 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 O2 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 4-2and 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 3-1and 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).
