Connect Line Voltage
1. Remove screw (18, Figure 9-4), cover lock (19), captive washer (20),
and left side blind cover (17) from the remote electronics.
2. Connect the line, or L1, wire to the L1 terminal and the neutral, or L2
wire, to the N terminal (Figure 2-10). The Hazardous Area Oxymitter
5000 will automatically configure itself for 90-250 VAC line voltage and
50/60 Hz. To avoid a shock hazard, the power terminal cover must be
installed.
3. Connect fieldbus Digital Signal and Logic I/O Calibration Handshake
Leads (Figure 2-10). Use individual shielded twisted wire pairs.
Terminate the shield only at the electronics housing.
a. Fieldbus Digital Signal. The fieldbus digital signal carries the O
2
value. This digital signal can also be used to communicate with the
Oxymitter.
Calibration Handshake
Logic I/O
1. The output signal can be used to trigger an alarm or to provide a
calibration handshake signal to an IMPS or SPS 4001B.
a. If autocalibration is not utilized, a common bi-directional logic contact
is provided for any of the equipment alarms listed in Table 8-1. The
assignment of alarms that will actuate this contact is modified by one
of seven additional configuration settings (mode 1 through mode 7)
listed in Table 4-1.
b. The logic contact is self-powered, +5 VDC, with a 340 ohm series
resistance. An interposing relay is required if the logic contact will
annunciate a higher voltage device, such as a light or horn. An
interposing relay may also be required for certain DCS input cards. A
Potter & Brumfield model R10S-E1Y1-J1.0K 3.2 mA DC (or equal)
interposing relay will be mounted where the contact wires terminate
in the control/relay room.
2. Install cover (17, Figure 9-4) and secure with captive washer (20), cover
lock (19), and screw (18).
If using an IMPS 4000 or an SPS 4001B, install it in a non-hazardous, explosive-free
environment.
