Brownian motion can no longer support them. Due to the high density of the particle, flocs will form and settle as fine sludge. MICROTSCM (07/09) Page 3 REV 2.4... -

MICROTSCM (07/09) Page 4 REV 2.4... -
Page 9: Charge Analysis
Measurement: The potential developed as the result of forced movement of particles in the solution. This is the method used by the MicroTSCM. Continuous sample water is directed into an annulus, inside which a displacement piston oscillates vertically at a fixed frequency. This action causes the liquid to move between the two stainless steel electrodes. -

Suggestion: If meeting the minimum flow rate may be a problem, the optional flow alarm may be required. HF Catalog #19886. See section 8.3. To prevent large debris from entering the sample chamber, a 40 mesh screen strainer is recommended. MICROTSCM (07/09) Page 6 REV 2.4... -

Page 12: Analyzer Mounting
The analyzer can be flipped on its mount to gain access to the electrical connections. Please refer to the drawing below for mounting dimensions and hole location. Figure 5: Analyzer Mounting MICROTSCM (07/09) Page 8 REV 2.4... -
Page 13: Electrical Connections
Use twisted pair shielded cable 22AWG-14 AWG for the voltage or current outputs. Tie the shield at the recorder end only. Do not connect the shield at the analyzer. The voltage connections are made at J6 as shown below: MICROTSCM (07/09) Page 9 REV 2.4... -
Page 14: Alarm Contacts
In all cases the following connections apply: Terminal 1: Normally Closed (N.C) Terminal 2: Normally Open (N.O.) Terminal 3: Common (C) Do not use wire larger than #14 AWG as the terminal blocks will not accept it. MICROTSCM (07/09) Page 10 REV 2.4... -

Page 18: Calibration
Calibration The MicroTSCM has been calibrated at the factory, however to ensure accuracy it is recommended that the instrument be calibrated prior to being placed online. Long term drift may occur in this instrument and HF scientific recommends calibration every three months. -
Page 19: Automatic Control
7.2 PI Control Overview The MicroTSCM can be incorporated into an existing control scheme using the 4-20mA or serial outputs. Plant control can also be achieved using the optional Proportional Integral feature included in the MicroTSCM analyzer (HF Catalog # 19550 only). -
Page 20: Pi Control Procedure
7.3 PI Control Procedure The assumption is that the wiring between the MicroTSCM analyzer and the dosing pump has been installed. The following procedure is recommended to determine the correct Proportional - Integral (PI) values for any particular system. -
Page 21: Entering The Control Parameters
7.3.2 Entering the Control Parameters The next step is to enter the control parameters into the MicroTSCM analyzer. To do this, follow the steps: 1. Press /Menu to enter the Main Menu screen. -
Page 22: Additional Features And Options
The optional remote panel meter allows for remote indication of the SCU reading using the 4-20 mA loop of the MicroTSCM. No external power is required, as the meter is powered from the 4-20 mA source of the MicroTSCM analyzer. -

11. Rotate the motor slowly by hand to ensure the probe does not hit the cell bottom. If there appears to be any contact adjust the probe up slightly. 12. If the probe does not rotate freely inside the cell, check for obstructions. This condition will cause premature motor wear. MICROTSCM (07/09) Page 19 REV 2.4... -
