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.

9900 Transmitter

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 Module wiring

The alarm is OFF during normal operation, and will go ON when relay energizes according to 9900 Relay settings.

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)

The 9900 open collector and 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.

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.
