OCX 8800
Instruction Manual
Install OCX 8800
Observe the following cautions when installing the OCX 8800 in a hot process stack. If the process is shut down and cooled, the transmitter can be installed in the stack prior to connecting the pneumatics and wiring.
Before installing the OCX 8800 into a hot stack or ductwork, make sure that the OCX 8800 is turned on and at normal operating temperature. Exposing a cold OCX transmitter to hot process gases can cause permanent damage to the equipment.
Whenever a positive stack pressure exists at the installation site, be sure to connect all pneumatic lines prior to installing the OCX 8800 in the stack or ductwork. Failure to connect the pneumatic lines can allow the flow of contaminants into the OCX 8800 ports.
1.Connect the test gas lines and the instrument air lines to the electronics housing.
2.Remove the electronics housing cover.
3.Install customer power and signal conduits and wiring at the electronics housing.
4.If used, connect external relay leads to the alarm output relay terminal block, Figure
5.Connect the O2 and COe signal leads to the
6.Connect the line (L1 wire) to the L1 terminal, and the neutral (N wire) to the N terminal on the AC power input terminal block.
7.Connect the ground lead to the ground stud. Secure the connection with two nuts. Attach a separate ground lead (G wire) from the ground stud to the G terminal on the power input terminal block.
8.Install the cover on the electronics housing.
9.Restore power to the system. Allow OCX to reach normal operating temperature before installing in a hot process stack.
10.Bolt the OCX 8800 to the stack and install insulation. Refer to Figure
11.Turn on the test gasses at the cylinders and open the instrument air supply valve.
