3-9950.090 Rev. C 05/17

Description

The 9950 Dual Channel Transmitter is a two channel controller that can support two sensors of same or different types in one instrument. The sensor types supported by the 9950 are Signet Flow, pH/ORP, Conductivity/Resistivity, Salinity, Temperature, Pressure, Level, Dissolved Oxygen, and devices that transmit a 4 to 20 mA signal with the use of the 8058 iGo® Signal Converter.

The 9950 includes advanced features such as derived functions, advanced multiple relay modes, and timer based relay functions. Derived functions allows for the control of a relay or current loop with the sum, delta (difference), or ratio of two measurements. Multiple relay modes allow up to three signals to be used for the control of a single relay, and can be any combination of analog and binary inputs. The timer relay modes allow a relay to be activated on a repeating basis from every minute to once every 30 days. Weekday timer mode allows a relay to

3-9950.393-1 159 310 268 Relay Module - 4 Mechanical Relays

3-9950.393-2 159 310 269 Relay Module - 2 Mechanical Relays, 2 Solid State Relays

3-9950.393-3 159 310 270 Relay Module - 2 Mechanical Relays , 4 Binary Inputs

The 9950 has a slot for an optional Relay Module for any of the modules listed above.

• Dry-contact relays are electromechanical switches with a moving contact armature. They are suitable for many general-purpose applications, AC or DC, including AC loads up to 250 V.

• Solid-state relays are electronic switches with no moving parts. They may be used with AC or DC loads, but have lower current handling capability and voltage ratings than Dry-contact relays. Solid-state relays will outlast Dry-contact relays in pulsing applications. 30 VDC/ VAC maximum.

• The four Binary Inputs can detect if an external sensor or switch is open or closed. The switch state can be used to control the relays in the module relay activation and are not considered an input measurement.

. The four binary inputs only control

3-9950.393-3

For wiring information, refer to the Relay Wiring section, page 7.

The 3-9950.393-3 module can be set to supply power to the external switch/ sensor. For switches/sensors that require power set the Int/Ext switch to the Int positions. If the external Switches/Sensors are powered set the Int/Ext switch to Ext. Important for externally powered switches/sensors ensure the output signal is within the allowable range for the 3-9950.393-3.

NOTE:

• The four red Indicator LEDs on the front panel of the 9950 show the status of relays 1, 2, 3, & 4. The LEDs will activate with or without a relay module installed.

• Hysteresis and time delay are adjustable for each relay.

CAUTION

Switching active loads (usually inductive) can cause contact arcing sufﬁ cient to damage the relays.

The RC Filter Kit or “snubber” (part number 3-8050.396) is available as an accessory to reduce or eliminate these damaging effects. Recommended for inductive loads greater than 50 VAC (remote relays, solenoids, pumps, etc.)

Signal Type: Frequency

Signet ﬂ ow sensors 515/8510, 525, 2000, 2100, 2507, 2536/8512 and 2540 provide a frequency output. (Flow sensors 2537, 2551 and 2552 can be conﬁ gured with either Digital (S3L) or Frequency outputs).

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 9950 carry frequency data signals from the sensor.

• The 9950 has a selection for 515/525 under the input menu. Select "Yes" for optimum signal performance.

• 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.

• 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.

In case of noise interference, connect the cable shield to earth ground.

Maximum total cable length of the Digital (S3L) Bus:

The quality of the cable used in the bus determines the maximum length. The maximum cable length may not exceed 305 m (1000 ft), regardless of current requirements.

Relay Modes

The 9950 relays are selectable and conﬁ gurable and can be used as switches that respond when the process value moves above or below a user-deﬁ ned setpoint or it can be used to generate a pulse at a rate proportional to the process value. They can be used for Low Alarm, High Alarm or Proportional Pulse triggering related to the process value. All relay functions are set up in the RELAY menus.

Generation II, or greater, supports the ability to activate the Red Backlight when a relay is activated. An optional check box is displayed during the programming of a relay that will turn the Red Backlight on when the relay is activated. The Red Backlight can be activated by any relay or relay mode. Generation II, or greater, English, French, German, or Spanish Languages only. The relays can have a custom label assigned for easy of identiﬁ cation.

Low Setpoint:

Relay is on when the measured value is less than or equal to the setpoint. Relay turns off when the measured value is equal to or greater than the Low Setpoint + Hysteresis

High Setpoint:

Relay is on when the measured value is greater than or equal to the setpoint. The relay turns off when the measured value is less than or equal to the High Setpoint - Hysteresis.

Cycle High/Low:

The relay will energize 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 cycle time completes and either the process value goes below the set point minus the hysteresis for Cycle High or goes above the setpoint plus the hysteresis for Cycle Low.

In FLOW, Cycle High activates the relay each time the volume reaches the SET VOLUME setpoint (see page 23).

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 is 300 pulses per minute.

Example usage would be to control solenoid-operated

dosing pumps.

For example: As the process value rises above 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 will ﬂ ash 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 9950 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 will ﬂ ash 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

The relay will activate for the set pulse width once the speciﬁ c volume of ﬂ uid is registered. Flow Inputs only.

NOTE: Relay LEDs will turn on when the relay is active

• Totalizer Volume

Relay activates and latches when a speciﬁ ed volume of ﬂ uid is registered on the resettable totalizer. 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 below the set point or the resettable 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.

Relay Modes

• Multiple

When a Relay Source is set to "MULTIPLE," the mode presents four Boolean logic formulae called "Relay Operators." Each Operator can be programmed with up to three different conditions. The relay will only be activated when the complete formula is satisﬁ ed.

Boolean Relay Logic Operations

RELAY 1

MODE

FLO(A | B | C)NITS

(A l B l C) means "Activate this relay when any condition (A, B, or C) is true."

Example: Set Relay 1 Mode to A | B | C. "This relay will activate IF channel 1 pH falls below 6, OR if channel 2 pH rises above

7.8, OR if binary input 1 is active (On or Closed). Relay #1 will activate 30 seconds after any one the conditions are met" Condition A: The pH on Channel 1 is less than 6. Condition B: The pH on Channel 2 is greater than 7.8 Condition C: Binary Input 1 is On. On Delay: 30 When operating properly, all three of these conditions are FALSE. If any one of them becomes TRUE, then Relay 1 will be activated.

Relay 1 will remain activated until the TRUE condition becomes FALSE again, including the hysteresis band.

• Binary

When the relay source is set to “Binary." The Binary Inputs can sense if the input is ON (Closed) or OFF (Open). The four binary inputs only control relay activation and are not considered a measurement source. Each binary mode is independent and each of them can be assigned to a relay mode.

(A & B & C) means "Activate this relay only when all conditions (A, B, and C) are true."

RELAY 1

MODE

A & B & C

(A l (B & C) ) means "Activate this relay if A is true OR if B AND C are both true."

Example

A 2282 Guided Float Switch is mounted in a tank. The output of the Float Switch will prevent a relay from activation if the tank is below the position of the Float Switch.

RELAY 1

MODE

A | (B & C)

RELAY 1

MODE

A & (B | C)

(A & (B l C) ) means "Activate this relay only if A is true AND either B or C are also true."

• Timer

When the “Timer” relay source is selected, the time can be selected using Period or Weekday modes. Both relay modes work directly with the time settings and formats that are entered at start up or adjusted in the options menu. The relay is normally open until the speciﬁ ed time is reached, at which time the relay is closed, triggering the relay for a speciﬁ ed duration. The “Hold while” feature allows the user to hold the measurement from a channel input 1, 2, or both, or none for a speciﬁ ed recovery time. The 9950 will deactivate held relays and hold the 4 to 20 mA at previous value.

• Period Mode lets the user set a periodic interval, in days, hours or minutes, at which the relay will activate. A First Start screen lets the user set the day and time for the Period Mode to begin.

• Weekday Mode lets the user speciﬁ c the days of the week, Sunday, Monday, Tuesday, Wednesday, etc., at which the relay will activate. A Start Time screen lets the user set the time of day for the weekday activation. Weekday Mode does not have a Start Delay parameter.

Caution:

If HOLD WHILE RELAY # ACTIVE setting is changed while an Activation or Recovery is in process, the setting will be applied after the cycle is complete. To apply the change immediately, cycle power to the 9950.

Derived Functions

When two of the same type of measurement are present, the 9950 can calculate several derived functions from like pairs of measurements. Up to four derived Functions can be deﬁ ned and used as the source for display and output functions.

• Flow, Temperature, Pressure, Conductivity and Level channels must have matching units. (Flow channels must also have same time base).

• Conductivity channels will automatically scale to S/cm before the function calculation is made.

• Three types of derived measurements can be applied to any set of sensors, regardless of type.

• Ratio: Measurement 1 ÷ Measurement 2 or Measurement 2 ÷ Measurement 1

• Delta (Difference): Measurement 1 - Measurement 2 or Measurement 2 - Measurement 1

• Sum: Measurement 1 + Measurement 2

• Custom labels can be assigned to Derived Functions for ease of identiﬁ cation

% Passage and % Reject

• % Passage and % Reject are derived functions based on conductivity measurements only, speciﬁ cally for use in reverse osmosis systems.

• % Passage is the amount of contaminates remaining in the product water compared to the level of contaminates in the feed water. For example, if the feed water measures 375 S and the product water measures 18.75 S, the % Passage is

(18.75/375) x 100= 5%.

• % Reject is the amount of contaminates rejected to the concentrate water compared to the amount of contaminates in the feed water. For example, if the feed water measures 375 uS and the product water measures 18.75 uS the % reject is [1-(18.75/375)] x 100 = 95%

• Decreasing Reject values and increasing Passage values usually indicate a problem with the RO membrane.

% Passage: (Permeate ÷ Feed) x 100

% Reject: [1 - (Permeate ÷ Feed)] x 100

% Recovery

• % Recovery is a derived function based on ﬂ ow rate, in a reverse osmosis system.

• To measure % Recovery, the 9950 must have two ﬂ ow sensors connected. They may be located in the Feed line, the Concentrate line or the Permeate line.

• The 9950 provides 3 different methods for calculating Recovery to accommodate any conﬁ guration.

• Both ﬂ ow sensors must use the same time base and units of measure.

% Recovery A: (Permeate ÷ Feed) x 100 In the Setup menu, select the option that states % Recovery A,

FEED: PERMEATE

% Recovery B: Permeate ÷ (Permeate + Concentrate) x 100 In the Setup menu, select the option that states

% Recovery B, PERMEATE: CONC

% Recovery C: [(Feed - Concentrate) ÷ Feed] x 100

In the Setup menu, select the option that states

% Recovery C, FEED: CONC

9950 Field Software Upgrade

The 9950 upgrade ﬁ le will be available on the Georg Fischer website. You will need a USB ﬂ ash drive that is formatted, using Microsoft Windows, in either FAT16 or FAT32 format. Do not use exFAT or NTSF formats. These are incompatible with the 9950.

The upgrade ﬁ le is named Update.Fwc. Copy the ﬁ le to the root directory of the Flash Drive. Do not change the name of the ﬁ le or store the ﬁ le in a sub directory on the Flash Drive. The 9950 will only look in the root directory for the speciﬁ c ﬁ le, Update.Fwc.

Important! Do not use a USB extension cable. The USB ﬂ ash drive must be directly connected to the 9950 USB port.

Sample Flash Drive Directory with Update File

Updating the 9950

1. Disconnect power from the 9950.

2. Insert the Flash Drive into the 9950 USB slot.

3. Reconnect power to the 9950.

4. LED 1 on the 9950 will ﬂ ash quickly as the unit searches for a Flash Drive and the correct ﬁ le.

5. When the 9950 detects a Flash Drive and a valid update ﬁ le, LED 2 will slowly ﬂ ash during the update process.

6. The update process takes approximately 30 seconds.

7. After a successful update the 9950 will boot to the normal screen.

8. After a successful update disconnect power, remove USB drive, reconnect

power, review application settings.

Troubleshooting

If, after 10 seconds, the unit boots to the normal screen, the 9950 was unable to ﬁ nd the Flash Drive or the ﬁ le.

a. Please ensure the Flash Drive has been formatted in

either FAT16 or FAT32 format, the upgrade ﬁ le is in the root directory of the Flash Drive, and the ﬁ le name is Update.Fwc. You may also need to try a different ﬂ ash drive.

b. If LED 4 on the 9950 is continuously illuminated, this

indicates either the ﬁ le found on the Flash Drive is corrupted, or power was interrupted during the upgrade process.

• Remove power from the 9950.

• Remove the Flash Drive.

• Apply power to the 9950.

c. If the 9950 starts normally, the ﬁ le on the Flash Drive was

corrupted.

• Download a new copy of the update ﬁ le and copy it to the Flash Drive.

• Repeat the update instruction with the new ﬁ le.

d. If the 9950 starts up and stops with LED 4 on and a

blank screen, this indicates that the update process was interrupted and the 9950 cannot start.

• Disconnect power from the 9950.

• Reattach the Flash Drive to the 9950.

• Repeat the upgrade procedure.

e. If the 9950 still does not respond after the second

upgrade attempt,

• Download a new copy of the update ﬁ le and copy it to a different Flash Drive.

• Repeat the update instruction with the new Flash Drive.

Averaging

NO AVERAGING, NO SENSITIVITY

With SENSITIVITY set to 0 (zero) and AVERAGING set to OFF (0 seconds), the 9950 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 zero 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 is different depending on the measurement type. Seconds to 99.5% of Final Value for Low, Med, and High are:

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 SETPOINT) and the ending or maximum conductivity value (20 mA SETPOINT). 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 required, they can be calculated in mA. Then the mA value can be checked directly.

Inside the 9950 the following equation is used:

NOTE:

If ADJUST 4 mA or ADJUST 20 mA is used, the mA value can be affected. To prevent any problems the adjust function should only be used to get exactly 4.0 and 20.0 at the PLC. The 9950 is accurate and the adjust functions are only needed to compensate for an offset due to noise or a not-so-accurate PLC input card.

The error value of either 3.6 mA or 22 mA should be tested ﬁ rst before applying the conductivity equation.

Level and Volume Calculation in Custom Shaped Vessels

In the LEVEL/VOLUME menu, if Custom Shape is selected in the INPUT menu, you can deﬁ ne from three to ten 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 conﬁ guration).

• Select Automatic Level Measurement mode to accept the sensor measurement of the Level, while you assign a volumetric value to each custom point (wet conﬁ guration).

• Enter from 4 to 32 custom points to link level and volume values.

• The ﬁ rst custom point must be the lowest ﬂ uid level in the vessel. Each successive point must be greater than the preceding point.

• The last point must be equal to or greater than the highest ﬂ uid level in the vessel.

• A custom point should be located at all transition points in the vessel shape (for example, at custom point #9, where the shape changes from a cylinder to a cone).

• The more complex sections should be deﬁ ned with more points. NOTE: The conical section of the illustration has been deﬁ ned by custom points 1 through 9. More complex tanks will require additional points to ensure an accurate calculation.

• Simpler sections require fewer deﬁ ning points.

NOTE: A cylinder requires only custom points 9 and 10.

Volume Calibration Procedure

1. Press ENTER to start the volumetric calibration period. The 9950 starts counting pulses from the ﬂ ow sensor.

2. Press ENTER to stop the volumetric calibration period. The 9950 stops counting pulses from the ﬂ ow sensor.

3. Enter the volume of ﬂ uid known to have ﬂ owed past the sensor during the volumetric calibration period. This will modify the existing Flow K-Factor.

4. The 9950 displays the newly calculated K-Factor for your reference. (If the calculated K-Factor is less than 0.0001 or greater than 999999 (out of range at either extreme), the 9950 displays "ERROR VOLUME TOO HIGH" (or LOW) and returns to VOLUME CAL.)

5. Press ENTER to accept the new K-Factor (9950 displays "SAVING") or press + keys simultaneously to escape without saving and return to Enter Volume. NOTE: You may enter your own calculated K-Factor in the CAL menu.

USP Limits

USP (United States Pharmacopeia) 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 9950 has the USP limits stored in memory. It will automatically determine the proper USP limit based on the measured temperature. Important Conductivity TEMP COMP must be set to NONE and Unit Of Measure must be set to S.

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 9950 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 PERCENT 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 9950 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).

(μS)

NOTE: Relay will activate if USP limit is exceeded, Temperature Comp is set

to Linear or Pure Water, Conductivity Measurement is NOT in uS, or if the Conductivity Sensor Electronics is indicating a measurement error.

Maintenance

• Clean the instrument case and front panel with a soft cotton cloth dampened with a mild liquid soap solution.

• Never wipe the front window with static retentive cloths such as wool or polyester which may induce a static charge. If a static charge develops on the window, you may notice temporary blotches form on the screen. When this occurs, clean the front window with an anti-static cloth, or a soft cotton cloth and antistatic spray or a mild liquid soap solution to remove the static charge.
