Wiring

System Start-up: Step 2

Wire the transmitter for all connections with the power off. Keep any 4 to 20 mA and relay-actuated output devices that are connected to it ofﬂ ine at this time. Connect the sensors (page 11), power (page 17) and relay(s) (page 18).

Next step: Relay Functions (see page 19).

Wiring Tips:

 Do not route the sensor, DC power, or 4 to 20 mA cables in conduit containing

AC power wiring. Electrical noise may interfere with sensor signal.

 Routing the sensor cable in grounded metal conduit can help prevent electrical noise

and mechanical damage.

 Seal the cable entry points to prevent moisture damage.  Only one wire should be inserted into a terminal.  Splice double wires outside the terminal or use appropriate wire ferrule,

not to exceed 2 mm (0.08 in) diameter.

All wiring connections to the 9900 are made via removable terminals.

In general:

 The Power, Loop and Open Collector plugs and the Relay Module plug accept

12 to 28 AWG wire. The S3L/Freq plug and the Cond/Res Module plug accept 16 to 28 AWG wire.

 Strip 7 mm (0.28 in.) of insulation from wire tips and tin bare ends to eliminate fraying.  Insert wire tip or ferrule completely into the terminal and secure with the screw.  Do not allow any AC leads that may be connected to the internal relays to come in

contact with low voltage wiring.

Tools Required

 Phillips screwdriver  Flat-head screwdriver  Wire strippers

For Field Mount installations, refer to the wiring diagram inside the Field Mount housing.

CAUTION:

Avoid Electrostatic Discharge (ESD)

 Minimize handling of plug-in modules to reduce the

possibility of damage due to ESD.

 Handle modules by the edges. Never touch any exposed

circuitry or contacts.

 Wear an anti-static wristband or stand on an anti-static mat,

or keep one hand touching a properly grounded pipe or other properly grounded piece of metal when handling modules.

Signal Type: Frequency

Signet ﬂ ow sensors 515/8510, 525, 2000, 2100, 2507, 2536/8512 and 2540 provide a frequency output. (Flow sensors 2551 and 2552 can be conﬁ gured with either Digital (S or Frequency outputs, see page 13.)

The maximum allowable cable length for sensors with frequency output is dependent upon the output signal strength of the sensors themselves, and the degree to which the signals are susceptible to EMI or "noise." This is largely a function of whether the sensors are self-powered (515/8510 and 525), or powered by an external source.

 The input terminals on the 9900 carry frequency data signals from the sensor.  Do not route sensor or output cables in conduit containing AC power wiring.

Electrical noise may interfere with sensor signal.

 Routing cable in grounded metal conduit will help prevent electrical noise and

mechanical damage.

 Seal cable entry points to prevent moisture damage.  Only one wire should be inserted into a terminal. Splice double wires outside the terminal.  In case of noise interference, ground the sensor SHIELD wire to a local earth ground

at a point near the sensor.

 Consult the sensor manual for additional wiring information.

Signal Type: Digital (S3L)

 The input terminals on the 9900 carry Digital (S3L) serial data from the sensor.  Do not route sensor or output cables in conduit containing AC power wiring.

Electrical noise may interfere with sensor signal.

 Routing cable in grounded metal conduit will help prevent electrical noise and

mechanical damage.

 Seal cable entry points to prevent moisture damage.  Only one wire should be inserted into a terminal. Splice double wires outside the terminal.  The TOTAL cable length from I/O devices to the transmitter must not exceed 305 m (1000 ft).  In case of noise interference, ground the sensor SHIELD wire to a local earth ground

at a point near the sensor.

 Consult the sensor manual for additional wiring information.  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.

 There are several methods that can help route the digital cables and remain within the

distance limitations.

• The 9900 Open Collector (R1) output provides high-speed switching capability. Signal frequencies can reach 400 pulses per minute.

• The 9900 Open Collector (R1) output connection is dependent upon the type of circuit being controlled by the output.

• Most indicating instruments or control system inputs require a signal voltage of 0 to 5 V (TTL or CMOS logic levels) or 0 to 24 V. Therefore, the 9900 Open Collector output circuits must be equipped with a pull-up or pull-down resistor (not supplied), and a quality regulated 5 to 24 V (depending on the application) power supply (not supplied) is recommended to function properly.

Relay Functions

System Start-up: Step 3

Set your relay functions to your own application requirements.

Next step: System Setup (see page 25).

Once a setting is saved it becomes immediately active.

1. Go to the Relay Menu (RELAY ﬂ ashing on screen, press ENTER).

2. If prompted, select desired source.

3. Press  to relay MODE selection screen.

4. If necessary, press  and then  or  to select R1 MODE LOW.

Press ENTER to confirm.

5. Press  to R1 SET LOW. Press  to enter GPM value of 5.5.

6. Press ENTER to save.

7. Scroll  to the R1 HYSTERESIS menu.

8. Press  to edit.

9. Set the hysteresis for this relay. This affects the turn off only: 2.5 gpm.

10. Press ENTER.

11. Scroll down  to the R1 ON DELAY menu.

12. Press  to edit.

13. Set the turn-on delay in seconds for the relay: 15.0.

14. Press ENTER.

15. Exit to View Mode.

 Relay function can be tested in the RELAY menu.

Example: Set a relay R1 to turn on at a low setpoint of 5.5 gpm with a time delay of 15 seconds and turn off at 8.0 gpm.

Remember,

SET LOW + hysteresis = OFF point:

5.5 + 2.5 = 8.0

Relay and Open Collector Outputs

RELAY HIGH and LOW Settings

Depending on the desired function of the circuit attached to the Open Collector (R1) output, it may be necessary to have the Open Collector turned “on” or “off” when the criteria for the activation of this output are met.

If the 9900 is set to operate in RELAY LOW mode, when the user-deﬁ ned condition for the activation is met (e.g. exceeding an alarm limit) the Open Collector switch is turned “on.” If wired as standard “NPN-style” output (see previous page) the logic level of the attached control system or PLC input consequently becomes “low” logic level (when NORMAL is set to OPEN).

If a high input logic level is required for activation, it can be accomplished in one of three ways. In order of preference,

1. Change the Open Collector (Relay 1) output function to “high” in the instrument's RELAY menu, or

2. Wire the Open Collector (R1) output “PNP” style as described on the previous page, or

3. Set the Open Collector (R1) to NORMAL CLOSED in the RELAY menu.

Fail-Safe Behavior

No matter the setting, the Open Collector output turns off if the 9900 loses power. This must be taken into account when evaluating system failure consequences. If the system layout requires a “closed” or “on” condition for the output in case of power loss, a mechanical dry-contact relay (NC contacts) must be used instead of the Open Collector (R1) output.

Voltage and Current Limitation

The supply voltage in the Open Collector output circuit MUST be limited to the speciﬁ ed maximum Open Collector voltage (see operating manual for speciﬁ c instrument). The use of a quality 5 to 24 V (depending on the application) regulated power supply (not supplied) is recommended.

The current through the Open Collector switch also must be limited. Typical Open Collector outputs allow only for 10 to 50 mA switch current. Exceeding this current limit can burn out the Open Collector output components immediately.

Load and Pull-Up/Down Resistor Considerations

By utilizing basic arithmetic and Ohm’s Law, the safe limits of load resistance can be determined. When the Open Collector switch is closed, almost the entire supply voltage is applied to the load (e.g., the pull-up or pull-down resistor, the alarm horn input, a potential power relay coil or annunciator lamp).The resulting current through the load and through the Open Collector switch, as well, can be calculated as:

(Current)

= (Supply Voltage) / (Load Resistance)

Cycle High/Low:

The relay can stay energized for a set length of time after the process value goes above (or below) the setpoint. The relay will stay on for the CYCLE TIME and then turn off, even if the process value is still above (or below) the setpoint. The cycle will not repeat until the process value goes below (or above) the setpoint minus the hysteresis after the relay times out.

In FLOW, Cycle High activates the relay each time the volume reaches the SET VOLUME setpoint (see page 28).

NOTE: To reset the timer (or volume in Flow): in the RELAY menu, select TEST RELAY function. The timer will reset to 0 if the condition no longer exists when the TEST is performed. The timer will restart if the condition still exists.

Proportional Pulse Operation:

The transmitter can output a pulse at the rate deﬁ ned by the settings in the CAL menu and the sensor input. The maximum pulse output from the relays is 300 pulses per minute. Example usage would be to control solenoid-operated dosing pumps.

For example: As the process value drops below the setpoint, the output will start pulsing in relation to the process value, the maximum pulse endpoint and the programmed pulses/minute. The pulse rate will change as the process value changes and approaches the programmed endpoint. This functionality can be used to precisely control the process.

The starting point, endpoint and maximum pulse rate are select able in the RELAY menus.

NOTE: Relay LEDs are not lit in PULSE mode.

• Pulse Width Modulation

PWM automatically varies the ratio of ON time to OFF time proportional to minimum and maximum range settings.

The relay period is the sum of the time a relay is ON and the time it is OFF.

Relay pulse width is the time the relay is ON.

The 9900 must be programmed with the relay period, and with the low and high setpoints.

NOTE: The PWM mode is not used for Pressure applications.

NOTE: Relay LEDs are not lit in PWM mode.

Example:

• The pulse width will be 0% of the relay period (relay always OFF) when the process value is less than the minimum range.

• The pulse width will be 100% of the relay period (relay always ON) when the process value is greater than the maximum range.

• The pulse width will be 60% of the relay period when the process value is at 60% of the span between the minimum and maximum range.

• Volumetric Pulse

A pulse is generated each time a speciﬁ ed volume of ﬂ uid is registered. For ﬂ ow inputs only.

NOTE: Relay LEDs are not lit in VOLUMETRIC PULSE mode.

• Totalizer Volume

Relay activates and latches when a speciﬁ ed volume of ﬂ uid is registered. For Flow inputs only.

Total Volume mode counts the TOTALIZER Units until the setpoint volume is reached, then turns on the relay until the resettable totalizer is reset.

If the Resettable Totalizer reading is greater than the setpoint, the relay will be turned on immediately. The relay will be off when the totalizer is reset to zero.

This mode is useful to trigger a reminder when a process is due, as for a backwash cycle or ﬁ lter change.

System Setup Menu

All of the basic system setup functions are automated in the 9900 for many sensors and sensor electronics. This includes identifying the sensor connected to the 9900, and conﬁ guring the display for the sensor. After installation and wiring is completed, apply power to the 9900.

When the 9900 is ﬁ rst powered on, it will attempt to determine the sensor type connected when ENTER is pressed (unit will display LOOKING FOR).

If no sensor is attached to the 9900, the words “TYPE” and “FLOW” are displayed.

If the 9900 does not identify your sensor type correctly, use the  and keys to select your sensor type.

As you scroll through the available sensor types, press  to select the desired sensor and then press ENTER.

You may change sensor type after initial power-on (if the sensor type is changed after your 9900 is already in service). Enter the INPUT menu, scroll to TYPE, press , and scroll to select the desired sensor type (you may be prompted for your password). Press ENTER. The bottom line will display ALL SETTINGS WILL BE RESET. ARE YOU SURE? The top line of the display will blink NO (unless switching from Factory mode). Press  or  to select YES.

Menu System

VIEW Mode Overview

The top level of menus is referred to as the VIEW Mode. This view displays measurement values as well as current outputs and relay status. The radial bar graph represents the measurement value that is also displayed in the 7-segment numeric ﬁ eld below the bar graph. The bar graph is primarily used to display the full scale range of the sensor, but can be scaled via a menu item.

During normal operation, the 9900 displays the VIEW mode.

 To select a display, press the  or  arrow keys.

The display selections scroll in a continuous loop.

 Changing the display selection does not interrupt system operations.  No password is necessary to change display selection.  Output settings cannot be edited from the View Mode.  The display will return to the VIEW mode if no button is pressed for 10 minutes.

MENU Mode Overview

The MENU mode enables the user to view and conﬁ gure all menu items. The ﬁ ve menus available are: CAL, INPUT, LOOP, RELAY, and OPTION.

MENU Mode is entered by pressing and holding ENTER for three seconds.

The  button is used to change the position of the blinking cursor. When the desired menu is blinking, press ENTER.

In the selected menu, use the  and  keys to navigate through the menu. Use the ,  and  keys to edit the selected item (see Menu Navigation discussion, page 24).

Error Handling

Errors occurring while in the VIEW Mode show a speciﬁ c message (e.g., CHECK SENSOR). This message is displayed every 10 seconds and stays on for 5 seconds. Once the error is resolved or cleared, the error message stops.

Scrolling

In some cases, more than one message or measurement may need to be displayed. This is accomplished by alternating the message portions across the screen.

To save the new selection, press the ENTER key. A message displaying “Saving…” will be displayed for 3 seconds. After this message is displayed, the newly selected value will be displayed, if applicable.

Password Overview

The password is often required to start editing. Once entered correctly, this password will not be needed for subsequent edits. However, once the menu system is exited, the password will again be required when edit mode is re-entered.

Your choice of password (STD or CODE) is selected in the Options Mode.

 STD

The standard (STD) password is , pressed in sequence. This password is designed to protect the 9900 from unintentional changes. It is best suited for systems where a group of people need to be able to change settings.

 CODE

The CODE default setting is 0000, adjustable to any 4-digit numerical code up to

9999. Using a personal code provides the maximum degree of security. This code can be modiﬁ ed in the Options mode.

In the MENU mode, if the wrong code or password is entered, an ERROR message is displayed.

To change your CODE, go to OPTIONS mode, enter your desired code and press ENTER. (The STD password cannot be changed.)

Averaging

NO AVERAGING, NO SENSITIVITY

With SENSITIVITY set to a large value and AVERAGING set to OFF (0 seconds), the 9900 responds immediately to every shift in the process. The dashed red line represents the actual output of the sensor in varying conditions.

AVERAGING ONLY

With SENSITIVITY still set to a large value and AVERAGING set to MED or HIGH the rate is stabilized, but a sharp change in rate is not represented for 8 to 32 seconds or longer.

AVERAGING AND SENSITIVITY

With SENSITIVITY at 50 and AVERAGING set to MED or HIGH, the rate is stabilized, while a sudden shift in ﬂ ow rate exceeding 50 units of measure will be displayed immediately.

NOTE: The SENSITIVITY function applies only to FLOW. The SENSITIVITY function has no effect if the AVERAGING function is set to OFF. Averaging will not function if the Sensitivity is set to 0 (Zero).

Important

With Averaging set to Off the Sensitivity function is disabled. With Sensitivity set to 0 (zero) the Averaging function is disabled.

LOG Current Loop Output

In Conductivity/Resistivity, the logarithmic (LOG) mode can be used when a very large measurement range is required, yet high resolution is needed at the low end (e.g. in a clean-in-place application where a high-resolution conductivity reading is needed at the low end, while a very high conductivity reading is needed when a cleaning cycle is in progress).

Only two parameters need to be set up, the starting or base conductivity value (4 mA SETPNT) and the ending or maximum conductivity value (20 mA SETPNT). The 4 mA setpoint may be larger than the 20 mA point (reverse span).

What equation should be put in the PLC?

Conductivity = 10

n = (mA input

If only ﬁ xed thresholds are of required, they can be calculated in mA. Then the mA value can be checked directly.

Inside the 9900 the following equation is used:

Custom Measurements

Technical Reference for Level, Volume, and Mass Measurement

The 9900 can automatically perform level, volume and mass calculations:

 Pressure-to-level  Mass  Volume

Pressure to level conversion:

Level = P ÷ (SG × D) where P = Pressure SG = Speciﬁ c Gravity of ﬂ uid

D = Density of water

With pressure in psi:

Level (meters) = 0.703069 × (P/SG)

With pressure in bar:

Level (meters) = 1.019715 × (P/SG)

Mass Conversion

m = D × SG × V

where m = mass of ﬂ uid D = density of water = 1000 kg/m SG = Speciﬁ c Gravity of ﬂ uid V = Volume of ﬂ uid (m3)

m (kg) = 1000 × SG × V

Volume Calculations

Vertical cylinder:

V = π × r where r = radius of cylinder

× h

h = height of ﬂ uid

Rectangular vessel:

V = w × l × h

where w = width l = length h = height

Horizontal cylinder:

V = A × L

USP Limits

USP (United States Pharmacopoeia) has deﬁ ned 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 9900 has the USP limits stored in memory. It will automatically determine the proper USP limit based on the measured temperature.

Using the USP function

USP setpoints are deﬁ ned as a percentage below the USP limit, so a USP alarm is always a HIGH alarm. The 9900 can be set to warn you if the conductivity approaches within a set percentage of the USP limit.

The following settings and conditions are required for a USP relay function:

1. In the RELAY menu:

• RELAY MODE must be set to USP.

2. In the INPUT menu:

• COND UNITS must be set to μS.

• TEMP COMP must be set to None.

Example:

• The water temperature is 19 ºC, so the USP limit is 1.0 S.

• The USP PERCNT is set to 40%.

• The relay will be activated when the conductivity value reaches 40% below the

1.0 USP limit, or 0.6 S.

• If the water temperature drifts to more than 20 ºC, the 9900 will automatically

adjust the USP limit to 1.1. The relay will now be activated when the conductivity value reaches 40% below 1.1 S (0.66 S).

H COMM Module Overview

How HART® Works

The HART® (Highway Addressable Remote Transducer) Protocol uses Frequency Shift Keying (FSK) to superimpose digital signals on top of the analog 4 to 20 mA current loop. This allows two-way digital communication to occur and allows additional information beyond the normal process data to be communicated to the 9900. This digital signal can contain data such as device status, diagnostics, etc.

The HART protocol provides two simultaneous communication channels: a 4 to 20 mA analog signal and a digital signal.The analog signal communicates the primary measured value using the 4 to 20 mA current loop.

Additional information is communicated using a digital signal superimposed on the 4 to 20 mA signal.

Communication occurs between two HART-enabled devices, in this application a Signet 9900 Transmitter and a PLC or handheld device, using standard wiring and termination practices. The HART Protocol communicates at 1200 bits per second without interfering with the 4 to 20 mA signal and allows the PLC or handheld device to communicate two or more updates per second to and from the 9900.

4 mA -

Time

Note: Drawing not to scale

Frequency Shift Keying

Digital Signal

Analog Signal

The HART protocol operates according to the master-slave method. Any communication activity is initiated by the master, usually a programmable logic controller (PLC) or a data acquisition system. HART accepts two masters: the primary master - usually the control system (PLC) - and the secondary master - a PC laptop or handheld terminal used in the ﬁ eld.

HART ﬁ eld devices - the slaves - never send without being requested to do so. They respond only when they have received a command message from the master. Once a transaction (i.e., a data exchange between the control station and the ﬁ eld device) is complete, the master will pause for a ﬁ xed time period before sending another command, allowing the other master to break in. The two masters observe a ﬁ xed time frame when taking turns communicating with the slave devices.

As deployed in the 9900 application, HART allows remote verifying, testing, adjusting and monitoring of primary and secondary device variables. Features available in the 9900 Transmitter with H COMM Module installed:

• Adjust 4 mA: Allows ﬁ ne-tuning to compensate for errors in other equipment connected to the 9900.

Adjust the minimum and maximum current output.

• Adjust 20 mA: Allows ﬁ ne-tuning to compensate for errors in other equipment connected to the 9900.

Adjust the minimum and maximum current output.

• Supports Multi-Drop Mode: Allows up to four 9900 Transmitters be installed in Multidrop mode.

• Supports all Universal HART Protocol Revision 7.2 commands

• Supports many Common Practice Commands

• Makes Primary and Secondary values available at PLC. Secondary values are sensor-dependent and

are available with Flow, pH, Conductivity, Resistivity, Salinity and Level sensors.

H COMM Module Installation

If the 9900 Base Unit will be mounted in a panel, plug-in modules may be installed either before or after the base unit is mounted. If the 9900 Base Unit will be mounted using the accessory wall mount kit

(3-9900.392), install plug-in modules ﬁ rst.

If the Direct Conductivity/Resistivity Module will be included in your unit, install the H COMM module ﬁ rst and then install Conductivity/Resistivity Module over the H COMM Module.

To install the H COMM module, carefully align the module pins into its plug (see illustration) and push the module straight in until the tabs on the bottom edge snap into place.

To uninstall, squeeze tabs, grasp the module and pull straight out.

Be careful not to bend the pins when installing or removing the module to or from the base unit.

NOTE:

The black rubber jumper adjacent to the power terminal should only be removed when both the H COMM Module is utilized and the required sensor cable length is over 304 m (1000 ft).

unless otherwise noted.

Multi-Drop Mode

Up to four 9900 Transmitters can be connected in Multi-Drop mode using the H COMM Module.

To ensure proper operation in Multi-Drop mode, conﬁ gure each 9900 Transmitter with its own poll address using a conﬁ guration tool (laptop or hand-held device).

After conﬁ guring the 9900 Transmitter for multi-drop function, reset the Transmitter (remove power for ﬁ ve seconds then apply power) before use.

H COMM Module Operation

Loop Powered systems require a minimum of 24 VDC. If connecting with DC, nominal 12 VDC is acceptable. (See Power Wiring, pg. 17)

• In LVL/VOL mode, the primary variable will always represent Level, the secondary variable will always represent Volume.

• In pH, Conductivity, Resistivity and Salinity systems the secondary variable represents Temperature.

• In Flow, the secondary variable represents the Totalizer. Select Permanent or Resettable Totalizer in the Input menu (pg. 32).

Loop Current Trim Procedure

The Loop Current HART commands allow a Master HART device to update a loop current value in the 9900 Transmitter and to perform a two-point calibration (zero and span) of the loop current.

1. Use Command 40 (Enter/Exit Fixed Current Mode) to update the 4.00 mA current.

2. Using the measured value of your reference instrument (either a digital multimeter or the HART Master device),

set the zero trim using Command 45 (Trim Loop Current Zero). The transmitter will then trim its calibration and return the loop current value in the response message. The response value may differ slightly from the value sent by the Master due to rounding.

3. Use Command 40 (Enter/Exit Fixed Current Mode) to update the 20.00 mA current.

4. Using the measured value of your reference instrument (either a digital multimeter or the HART master device),

set the span trim using Command 46 (Trim Loop Current Gain). The transmitter will then trim its calibration and return the loop current value in the response message. The response value may differ slightly from the value sent by the Master due to rounding.

5. Repeat steps 1 through 4 as needed to gain the accuracy desired. Once the loop current is calibrated to your

satisfaction, return the device to normal operation by issuing Command 40 (Enter/Exit Fixed Current Mode) with a value of 0.0. This will take the 9900 out of ﬁ xed current mode.

Note: With the H COMM Module installed, the following functions are not accessible via the 9900 keypad:

• Trim Loop Current

• Test Loop Current These functions are only accessible via the HART interface.

Changes to Units of Measure in Transmitter

HART devices can be used to change the units of measure in a 9900 Transmitter. After an update, you must cycle power to the 9900 Transmitter (remove power for 5 seconds, then restore power). In a ﬂ ow system, the units update automatically and it is not necessary to cycle power to the 9900 Transmitter.
