9-4 HAZARDOUS AREA OXYMITTER 4000 REPAIR

Each of the following procedures details how to remove and replace a specific component of the Hazardous Area Oxymitter 4000.

It is recommended that the Hazardous Area Oxymitter 4000 be removed from the stack for all service activities. The unit should be allowed to cool and be taken to a clean work area. Failure to comply may cause severe burns.

Disconnect and lock out power before working on any electrical components. There is voltage up to 115 VAC.

a.Removal and Replacement of Hazardous Area Oxymitter 4000 Probe

1.Remove.

(a)Turn off power to the system.

(b)Shut off the calibration gases at the cylinders and the instrument air.

(c)Disconnect the calibration gas and instrument air lines from the Hazardous Area Oxymitter 4000.

(d)While facing the Hazardous Area Oxymitter 4000 and looking at the Rosemount label, remove screw (18, Figure 9-3or Figure 9-4), cover lock (19), and captive

washer (20) securing cover (17) on left side of housing (11). Remove the cover to expose the terminal block (15).

(e)Remove all signal and power wiring to the probe.

(f)Remove insulation to access the mounting bolts.

(g)Unbolt the Hazardous Area Oxymitter 4000 from the stack and take it to a clean work area.

(h)Allow the unit to cool to a comfort- able working temperature.

2.Replace.

(a)Bolt the Hazardous Area Oxymitter 4000 to the stack and install the insulation.

(b)Connect all signal and power leads at the probe. Refer to Section 2, INSTALLATION, for detailed wiring instructions.

(c)Install left side cover (17, Figure

9-3or Figure 9-4)and ensure it is tight. Secure the cover using cap- tive washer (20), cover lock (19), and screw (18).

(d)Connect the calibration gas and instrument air lines to probe.

(e)Turn on the calibration gases at the cylinders and turn on instrument air.
