AMI Turbitrace Product Description Product Description Application The AMI Turbitrace is used for the measurement of low level turbidity in pure and ultra pure water. Measuring Turbidity is a measure of how much of the light traveling through wa- ter is scattered by suspended particles. The scattering of light in- Principle creases with increasing suspended solid.
Page 10
AMI Turbitrace Product Description Measuring The light beam emitted by the emitter LED [L] passes through the sample and is received by the transmitted light beam sensor [J]. Principle Some light will be scattered by particles contained in the sample and received by the scattered light sensor [K], which is placed in a 90°...
Page 11
AMI Turbitrace Product Description On-line The sample flows through the sample inlet [F] via solenoid valve [G] and the manual 5 way valve [E] into the measuring chamber [B], Operation where the turbidity is measured. From there it flows through the sam- ple outlet [C] and the pressure regulator [K].

AMI Turbitrace Installation Installation 3.1. Installation and Setup Check List On-site require- AC variant: 100–240 VAC ( 10%), 50/60 Hz ( 5%) ments DC variant: 10–36 VDC Power consumption: 35 VA maximum. Protective earth connection required. Sample line with a flow rate of 5–20 l/h and a maximum pressure of 10 bar.
AMI Turbitrace Installation 3.2. Install the AMI Monitor The first part of this chapter describes the preparing and placing of the system for use. The instrument must only be installed by trained personnel. Mount the instrument in vertical position.
AMI Turbitrace Installation 3.3. Connect Sample and Waste 3.3.1 Connect Sample Inlet Use plastic tube (FEP, PA, or PE 4x6 mm) to connect the sample line. Mounting of Serto fitting SERTO fitting Compression ferrule Knurled nut Flexible tube Push the flexible tube [A] into the Serto fitting [D] and tighten the knurled nut [B].
3.3.3 Adjust the Sample Flow with a Capillary Tube The AMI Turbitrace is as standard delivered with the capillary FEP tube with an inner diameter of 1 mm and a length of 500 mm. If you have a low sample pressure or you need a high sample flow, a shorter capillary with 186 mm length can be used.
Page 20
AMI Turbitrace Installation The capillary tube determines the flow resistance and the maximal flow rate. With the pressure regulator at the inlet side of the capillary the flow rate can be adjusted within the given range, see diagram be- low.
AMI Turbitrace Installation 3.4. Electrical Connections WARNING Electrical hazard. Always turn off power before manipulating electric parts. Grounding requirements: Only operate the instrument from a power outlet which has a ground connection. Make sure the power specification of the instrument corre- sponds to the power on site.
Page 22
AMI Turbitrace Installation WARNING External Voltage. External supplied devices connected to relay 1 or 2 or to the alarm relay can cause electrical shocks Make sure that the devices connected to the following contacts are disconnected from the power before resuming installation.
AMI Turbitrace Installation 3.5. Connection Diagram CAUTION Use only the terminals shown in this diagram, and only for the mentioned purpose. Use of any other terminals will cause short circuits with possible corresponding consequences to material and personnel. A-96.250.131 / 130421...

AMI Turbitrace Installation 3.7. Relay Contacts 3.7.1 Input Note: Use only potential-free (dry) contacts. The total resistance (sum of cable resistance and resistance of the relay contact) must be less than 50 Ω. Terminals 16/42 If signal output is set to hold, measurement is interrupted if input is active.
AMI Turbitrace Installation 3.7.3 Relay Contacts 1 and 2 Note: Rated load 1 AT / 250 VAC Relay 1 and 2 can be configured as normally open or as normally closed. Standard for both relays is normally open. To configure a Re- lay as normally closed, set the jumper in the upper position.
Page 27
AMI Turbitrace Installation CAUTION Risk of damage of the relays in the AMI Transmitter due to heavy inductive load. Heavy inductive or directly controlled loads (solenoid valves, dos- ing pumps) may destroy the relay contacts. To switch inductive loads > 0.1 A use an AMI relay box available as an option or suitable external power relays.
AMI Turbitrace Installation 3.8. Signal Outputs 3.8.1 Signal Output 1 and 2 (current outputs) Note: Max. burden 510 Ω If signals are sent to two different receivers, use signal isolator (loop isolator). Signal output 1: Terminals 14 (+) and 13 (-)
AMI Turbitrace Installation 3.9.1 Signal Output 3 Terminals 38 (+) and 37 (-). Requires the additional board for the third signal output 0/4–20 mA. The third signal output can be operated as a current source or as a current sink (switchable via switch [A]). For detailed information see the corresponding installation instruction.
AMI Turbitrace Installation 3.9.3 HART Interface Terminals 38 (+) and 37 (-). The HART interface PCB allows for communication via the HART protocol. For detailed information, consult the HART manual. HART Interface PCB 3.9.4 USB Interface The USB Interface is used to store Logger data and for Firmware up- load.

AMI Turbitrace Maintenance Maintenance 6.1. Maintenance Schedule Preventive maintenance frequency depends on water quality, on the application, and on national regulations. Every week Check sample flow. If necessary Clean the measuring chamber. Replace the 0-point filter When maintenance Replace the humidity absorber.
AMI Turbitrace Maintenance 6.2. Cleaning the Measuring Chamber Line Bayonet lock cover Scattered light sensor Measuring chamber Transmitted light beam sensor Emitter LED Drain valve Cleaning To clean the measuring chamber proceed as follows: 1 Close the pressure regulator valve to stop the sample flow.
Page 39
AMI Turbitrace Maintenance 4 Clean the measuring chamber using a clean, soft tissue. 5 Clean the optical elements [C], [D] and [E] with another soft, clean tissue. 6 Close the measuring chamber with the cover. 7 Close the drain valve.
AMI Turbitrace Maintenance 6.3. Replacing the Humidity Absorber Dew point The instrument continuously measures the humidity and temperature inside the turbidimeter housing and calculates the dew point based calculation on these values. The dew point gives an indication of whether the humidity absorber still has sufficient capacity to prevent condensa- tion inside the housing.

AMI Turbitrace Maintenance Replacement procedure Screw cover Bayonet lock cover with New humidity absorber flask o-ring Saturated humidity absorber Turbidimeter housing To replace the humidity absorber proceed as follows: 1 Select <Maintenance>/<Replace Absorber> and confirm with [Enter]. This makes the two messages E068 and E006 disappear for three days.
AMI Turbitrace Maintenance 6 Screw the screw cover with the new humidity absorber flask into the measuring cell. 7 Tighten it well. Note: After replacing the humidity absorber, the dew point decreases only slowly. It may take several days until the dew point is below 3 °C again.
