If using the MIP supplied blower, the blower should be mounted about halfway (dual-model) between the
transmitter and the receiver or wherever is convenient to maintenance. Blower hoses should be kept short,
and not against the stack. Room should be allowed to swing the door open. Blowers draw 5A at 230 V. Single
blower boxes should be installed just close transmitter and receiver units.
3.
Attach all power supplies.
4.
With the purge air running, mount the transmitter, using the supplied bolts and vibration mounts. An
anti-seizing compound is recommended on the bolts.
5.
Route the conduit link and the receiver to the receiving side of the stack, being careful that the
conduit is not kinked, or pinched. Roll up any excess and tie down in a safe place, but not
permanently, since in some occasions it is necessary to bring the receiver to the transmitter to
perform a clear stack set up. The conduit contains the zero pipe, which is a fibre optic link and can be
damaged. Mount the receiver on the receiving side, again using the supplied mounting hardware and
vibration mounts. If bringing the receiver with the conduit attached to the transmitter side is very
difficult, a second zero pipe can be purchased.
6.
The communications link between the transmitter and the controller should be connected. Pay
attention to the terminal connections, # 7 and # 8 terminals are opposing on one end (RX to TX, TX to
RX). If using serial wire use at least 18 AWG 2 pair shielded, routed through conduit or a wire tray.
Serial wire lengths should be kept less than 500 m. If a longer run is necessary, local dealer can install
fibre optic modems. Fibre optic modems can run up to 3000 meters. Installation of fibre optic
modems requires special wiring to the monitor unit, and should be requested by the customer when
ordering.
7.
Plug all conduit connections inside the transmitter and the receiver with the gray sealing putty. This is
to prevent purge air from being lost through the conduit connections.
8.
After powering up the unit, the laser should turn on. Perform a cross-stack alignment (see
appendices) to ensure that the laser is striking the detector on center. Use the enclosed alignment
disk.
9.
The controller is a standard 19 “ rack mount, and only requires the power cord to be plugged in, and
any serial connections (or fibre links) to be connected.

APPENDIX A: ROUTINE MAINTENANCE
5.1.1
OVERVIEW
Maintenance, like many other pieces of analytical equipment is required periodically. While the instrument
was designed to be as maintenance free as possible, exposing a monitor to a dirty stack requires certain
cleaning procedures. To dictate a maintenance schedule to every user of the laser opacity and dust monitor
would be unreasonable, since all facilities and monitored processes differ in their particulate loading,
chemical make-up, heat, vibration and other physical attributes.
