MDS E-Scan NEMA 4X Console

1. MDS E-Scan Installation

1.1 Site Selection

The MDS E-Scan cabinet can be mounted in any area

where ambient conditions allow personnel to remain

for extended periods and is suitable for the atmosphere

and service conditions normal to a recovery boiler

installation. A vortex cooler or a cooling fan is

supplied with the cabinet to prevent excess heat build-

up. The cabinet should be kept closed to maintain

environmental resistance.

1.2 Power Requirements

The electrical power supply to the refractometer

system must be from a dependable non-interrupted

source. It is suggested that the power supply be the

same as that used for the auxiliary burner safeguard

system and the black liquor firing safety system. We

recommend that cables be run in conduit.

Note: The MDS E-Scan system is designed for a 120VAC power supply. If other voltages are

used, a transformer must be supplied.

Once the cabinet is fastened securely in place, the interconnecting wiring may be run between

TB13 and the control room. Use the interconnection diagram supplied in this manual for running

the interconnecting wiring. Close observance of the required shielding will ensure proper

operation of the Monitor. Signal wires should be kept separate from “POWER IN” and

“RELAY CIRCUITS” to the control room. After completing the interconnection wiring,

carefully recheck all connections to satisfy yourself that all are correctly terminated.

Important: Prior to shipment of an MDS E-Scan system, the sensing heads are

matched to the consoles and factory calibrated. DO NOT ATTEMPT TO CALIBRATE!
