Start-Up Guide
Look for the Quick Start icon to
quickly set up your new 9900.
The 9900 is compatible with all
GF Signet products listed in the
column to the right.
• pH and ORP electrodes require the
Signet 2750/2751 DryLoc®Sensor
Electronics (sold separately).
• Conductivity/Resistivity or Salinity
measurement requires either
the optional Direct Conductivity/
Resistivity Module (part number
3-9900.394) or the Signet 2850
Conductivity/Resistivity Sensor
Electronics (sold separately).
NOTE: If using the 2850, use ONLY
the one-channel Digital (S3L) models
3-2850-51/-61, or the 2-channel
model 3-2850-63 with only one
channel connected. Do not use
with both channels connected. The
4 to 20 mA models 3-2850-52 and
3-2850-62 are not compatible with
the 9900.
• Turbidity measurement using
Signet 4150 or Dissolved
• Oxygen measurement using
Signet 2610-31 requires Signet
8058 i-Go®Signal Converter
(sold separately).

The 9900 Transmitter, a member of Signet's line of SmartPro®
instruments, provides a single-channel interface for all Flow,
pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature,
Level, Dissolved Oxygen, Turbidity, Batch and other applications.
The 9900 is available in either Panel or Field Mount, runs on
10.8 to 35.2 VDC power (24 VDC nominal), and can power
certain sensors on loop power (see NOTE on page 7).
The 9900 Transmitter, also allows third-party 4 to 20 mA signals
to be used as an input (optional Signet 8058 i-Go®Signal
Converter required, sold separately).

Panel Mount Installation
Tools and Equipment Required
• Fine-tooth file
• ¼ DIN punch or jigsaw suitable for cutting panel opening to
within 1 mm (0.04 in) tolerance.
• ¼ DIN punches are available and recommended for creating
clean, precise openings quickly and easily in most instrument
panels.
• If a punch is not available, a jigsaw or other cutting tool can be
used. An adhesive template is provided to help guide the cutting
process. De-burr and smooth the opening with a file.
Installation
Do not mount in direct sunlight.
1. The panel mount transmitter is designed for installation
using a ¼ DIN punch. Recommended clearance on all sides
between instruments is 25 mm (1 in).
2. Place gasket on instrument, and install in panel.
3. Slide mounting bracket over back of instrument until bracket
snaps into latches on sides of instrument.
To remove:
1. Secure instrument temporarily with tape from front or
grip from rear of instrument. DO NOT RELEASE.
2. Press bracket clips outward and remove.
Field Mount Installation
Field mounting requires a separate mounting kit.
The 3-8050 Universal Mount Kit, the 3-8051 or 3-8052 Integral
Mount Kits, and the 3-9900.396 Angle Adjustment Adapter Kit
enable the transmitter to be installed virtually anywhere.
Detailed instructions for field installation options are included with
the 3-8050, 3-8051, and 3-8052 adapter kits.
For Field Mount installations with a Cond/Res Module, the Angle
Adjustment Adapter is required along with a 3-8050 or 3-8052
adapter kit to allow for sufficient clearance for the wiring.

System Start-up: Step 1
Prepare the transmitter installation location.
If the back of the transmitter is difficult to access when installed,
wire the removable terminal blocks first, then install it completely.
Next step: Wiring (Step 2).

59900 Transmitter Start-Up Guide
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
Wiring
For Field Mount
installations,
refer to the
wiring diagram
inside the Field
Mount Housing.
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 offline at this time.
Connect the sensors (pg. 7), power (pg. 13) and
Open Collector and relay(s) (pg. 14).
Next step: System Setup (Step 3).
• 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.
CAUTION:
Avoid Electrostatic Discharge (ESD)

Technical Notes:
• All of the electrical
connections to the
instrument are made
through the terminal box.
The connections are
labeled within the terminal
box and are self-descriptive.
• A plug is inserted into the
RS-485 cable bulkhead
when shipped to ensure a
watertight seal. Remove
and discard this plug when
cabling to this connection.
• The bulkhead will accept
cable diameters from
5.8 mm (0.23 in.) up to
10 mm (0.34 in.). The
terminals are designed to
accept wires in the range
of 14 to 28 AWG. All wires
should be stripped to a
length of 6 mm (0.25 in.).
• Ensure that the watertight
seal is maintained after
the terminal box has been
wired for operation. If any
of the bulkheads are not
tightened properly around
a cable or plug, the ratings
of the instrument will be
jeopardized and there is
a possibility of creating a
shock hazard.
• Do not run 4 to 20 mA
cables and power cables in
the same conduit.
Technical Notes:
• When using the 8058-2,
connect the loop source to
Channel 1 input ONLY.

Relay and Open Collector Wiring
• 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.

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 modified in the Options mode.

Sensor Choices
All of the basic system setup functions
are automated in the 9900 for almost all
sensors and sensor electronics.
This includes assigning the sensor
connected to the 9900, and configuring
the display for the sensor.
When the 9900 is first 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.
Press ENTER to save selection.
System Setup
System Setup: Step 3
Assign the appropriate sensor type for your system.
Refer to the 9900 Operating Instructions (3-9900.090) for detailed instructions
on calibrating your unit for your individual sensor type and adjusting your
Relay/Open Collector settings.
NOTE: The 9900 displays the
BATCH instrument type ONLY
if the Batch Module is installed.
