6. Wiring All wiring connections to the 8900 are made via the removable terminals of the plug-in modules. This section contains instructions and diagrams for wiring each type of module. Several helpful tables, explanations and recommendations are also provided. In general: • Do not allow any AC leads that may be connected to the Power Module, or to optional internal relays, to come in contact with low voltage wiring. • Terminals accept 12 to 24 AWG wire. • Strip 10 mm to 12 mm (0.4 in. to 0.5 in.
6.2 Digital (S3L) Input wiring • The maximum cable length of the digital (S3L) bus varies depending on the types of sensors connected and the size of the conductors in the cable. For best results, determine the maximum cable length for the system before routing cables. • Frequency input signals from flow sensors are not part of the digital bus, so they do not impact the cabling calculations. Follow the maximum cable specifications published in the flow sensor literature.
6.2.1 Digital Cable Length Calculations Step 1: Calculate the Total current requirements for digital (S3L) Branches This information will determine the total current consumption of all digital (S3L) sensors on a branch of the digital (S3L) bus, as a means of determining if the sensor load is within the current rating of the cable. Fill in the chart to determine the current requirements for a specific set of sensors.

8. System Setup Menu All of the basic system setup functions are automated in the 8900, with the exception of Channel Type assignments. These must be done by the user. After Channel types are assigned, the 8900 will automatically complete all of the remaining tasks in the System Setup menu. This includes assigning each sensor connected to the 8900 to a matching channel, and configuring one display for each channel. After installation and wiring is completed, follow the steps below.
8.2 Automatic Sensor Recognition: • Digital (S3L) sensors are detected at every power up, and placed on a list that identifies each by type and serial number. When new digital (S3L) sensors are detected, the 8900 displays "Found New S3L Devices" , then "Loading...Please wait". When completed, the display shows how many sensors are connected, and whether a Relay Module is detected.
8.5 Other Automatic Displays The 8900 will configure the following displays when appropriate: • For each channel assigned to flow, two display screens will be added to View; one for a permanent totalizer (Perm~), and another for a resettable totalizer (Rst~): • For each channel assigned to pH or ORP, a display screen showing the raw mV input from the sensor will be added.

Contrast: 3 > Auto Scroll: Off > Scroll Time: 4 secs > Func. 1 Type: Ratio > Func. 1 Source: ORP1-ORP2 > Clone Port: S3L > Clone Operation: Send > Clone Instrument: > Memo: gfsignet.
Appendix A: Derived Functions When two or more measurements of the same type are present, the 8900 can calculate several derived functions from like pairs. Up to three derived Functions can be defined and used as the source for display and output functions. • Flow, Temperature, Pressure, and Level channels must have matching units. (flow channels must also have same timebase) • Conductivity channels will automatically scale to μS/cm before the function calculation is made.
Appendix B: Level System Configuration The Signet 2450 Pressure sensor can be used to calculate level values. The following information is required for this mode: 1. 2. 3. 4. Determine where you want the level measurement to start. This is the Zero reference point (Z). Review the diagrams for your sensor type to help select the best option. Determine where you will mount the sensor. This is SLoc. Consult the Sensor manual for information regarding the best location for the sensor.
Level and Volume conversion in custom shaped vessels If you select Custom Shape in the Options menu, you can define from 2 to 20 Custom Points to establish the relationship of level to volume in the vessel. • Select Manual level Measurement mode to edit both level and volume data (dry configuration). • Select Automatic level Measurement mode to accept the sensor measurement of the Level, while you assign a volumetric value to each custom point (wet configuration).
Appendix C: Conductivity/Resistivity Application Temperature Effects Conductivity measurement is highly dependent on temperature. The basic rule is that higher temperatures result in greater conductance (less resistance). Temperature effects are expressed as the percentage of conductivity change (in μS) per °C. The conductivity value is generally referenced to 25 ºC.
Appendix D: USP Limits USP (United States Pharmacopoeia) has defined a set of conductivity values (limits) to be used for pharmaceutical water. The standard requires that conductivity measurement without temperature compensation be used for these applications. The limits vary according to the temperature of the sample. The 8900 has the USP limits stored in memory. It will automatically determine the proper USP limit based on the measured temperature.
Appendix E: Cloning using Digital (S3L) (Serial Cloning) Cloning enables copying the programming from one unit into another unit. After one 8900 is completely programmed, it becomes a Master (SEND) unit that can download its settings to a Slave (RECEIVE) 8900. Step 1: Controller Designations 1. 2. Designate the 8900 controller that will receive the data and refer to this controller as the Receiving Controller. Designate the other 8900 controller as the Transmitting Controller.
Step 4: Configure the Transmitting Controller 1. Now go to the Transmitting Controller’s Option menu and scroll until you see the “Clone Port” menu item and set the selection to “S3L”, if not already set. 2. Scroll down to the “Clone Operation” menu item and set it to “Send”, if not already set. 3. Scroll down in the Option menu until you see "Clone Instrument". 4. Press the right arrow key to toggle the selection choices. 5. Do not press the ENTER key yet.
Appendix F: BTU Quick Start Guide This guide outlines how to configure the 8900 Multi-Parameter to calculate Power and Energy. There are some limitations that must be known and requirements that must be adhered to in order for the calculation to work properly. The user can select power units, energy units, can show only the heating totalizer, show only the cooling totalizer or show both. The heating and cooling totalizers are all permanent totalizers.
Appendix G: 8900 display messages The 8900 communicates with the user to notify when something is wrong, and to inform of tasks underway. This appendix lists all of the messages that may appear during operation, and describes the purpose of the message. The calibration offset is limited in most measurements. The adjustment entered exceeds the maximum value.
