Installation Instructions
3.1 Selecting a Location
Factors such as air movement, gas density in relation to air,
emission sources and environmental variables affect correct
sensor location.
Air movement by fans, prevailing winds and convection should
be carefully evaluated to determine if a leak is more likely to
raise gas levels in certain areas within the facility.
Vapor density of a gas determines if it will rise or fall in air when
there are no significant currents. Lighter than air gases should
have the detector mounted 12 to 18 inches (30 to 45 cm) above
the potential gas leak, and heavier than air gases should be this
distance below the potential gas leak.
The Universal Series of gas detectors are designed for
rugged service in the field. However, sensors should
always be protected from environmental damage from
water, snow, shock, vibration and dirt.

3.2 Mounting the Enclosure
Install the detector to a wall or bracket using the predrilled mounting flanges shown in
Figure 1. If remote sensor option is included see Figure 2 for mounting dimensions of the
sensor housing.
After you have determined the appropriate location for your gas detector, it is important to securely
mount the gas detector using the predrilled mounting flanges on the enclosure (Figure1). Dimensions
for the mounting holes can be found for both the aluminum and poly enclosures in Figure 2.

3.3 Power and Analog Outputs Wiring
WARNING: Qualified personnel should perform the installation according to applicable
electrical codes, regulations and safety standards. Ensure correct cabling and sealing
fitting practices are implemented. Do not aim the sensor pointing upward.
Modular design simplifies the installation of the SensePoints. A top display assembly is mounted with
captive thumbscrews and is easily removed to access field-wiring terminals. Option boards mount to the
back of the display assembly, and power, input and output wires mount to the power supply board.
3.3.1
110-230VAC @15W Power Wiring
The SensePoint is powered by a 110-230VAC @ 15Watt power supply. Which has a full range AC Input
along with short circuit, overload, over voltage and over temperature protections. The SensePoint can
be ordered with the optional 2.3M AC power cord for ease of wiring and installation.
3.3.2
4-20mA Output Wiring
The SensePoint has a dedicated 4-20mA output terminal. Connect the 4-20mA signal wire to terminal
TB2.5 on the I/O Board for analog output.

3.4 Option Board Wiring
3.4.1
SensePoint RS 485 Option Board
The RS 485 Option (Figure 4) adds a single Modbus master port and a single Modbus slave port.
For the Modbus master port, connect your Modbus communication wires to terminals TB1.A and TB1.B,
and connect your shield wire to TB1.SHLD.
For the Modbus slave port, connect your Modbus communication wires to terminals TB2.A and TB2.B,
and connect your shield wire to TB2.SHLD. Note that there are two sets of terminals labeled TB2.A and
TB2. B. This allows you to connect multiple SensePoint gas detectors in series. Each SensePoint
represents an RS-485 slave and must have a unique Remote ID address (slave address). It is also
important to note that wiring should be daisy chained as opposed to a star pattern for reliable
operation. RC Systems recommends using shielded twisted pair cable such as Belden 3106A.

SensePoint Relay Option
The SensePoint Relay option (Figure 5) includes three programmable relays and a single programmable
RS 485 Modbus master or slave port. The relay labeled “FAILSAFE” is set up as a failsafe Fault relay by
default but can be configured as a programmable relay in the Relay Settings menu. It is possible to use
only the relays, only Modbus or both.
The relay terminals are labeled NO (Normally Open), NC (Normally Closed) or C (Common, or pole).
These designators correspond to the shelf, or de-energized, state of the relays. When a relay is in
Failsafe mode, it is energized when the alarm condition is not met, and therefore its action is reverse of
the designators.
For the RS-485 Modbus master/slave port, connect your Modbus communication wires to terminals
TB1.A and TB1.B, and connect your shield wire to TB1.SHLD.

3.5 Remote Sensor Installation
3.5.1
SensePoint Remote Sensor
Use of the Remote Sensor Option Board requires the SensePoint to be equipped with a RS 485 Option or
Relay Option Board. The Remote Sensor Option Board communicates to the SensePoint by utilizing one
of the RS-485 communication ports located on the option board.
Connect 24VDC and ground wires to the 24V and GND terminals on TB1 or TB2 of the Remote Sensor
Option Board to supply the necessary 24V. Connect the A and B terminals of TB1 or TB2 of the Remote
Sensor Option Board to the A and B Master Port terminals of the Relay/RS-485 Option Board.

3.6 Sensor Installation and Replacement
The SensePoint utilizes RC Systems’ Gen II Smart Sensors. These sensors come factory installed and
provide our highest level of performance with increased accuracy and signal to noise ratio. The 8conductor Smart Sensor interface connector attaches to the J1 connector on the base board, and the
detector detects the type of sensor automatically. This makes it easier than ever to switch from any of
our electrochemical Smart Sensors to any of our bridge (infrared, catalytic bead and PID) Smart Sensors
without having to reconfigure wiring.
3.7 Smart Sensors
WARNING: Prior to performing sensor replacement ensure the area has been declassified.
To install a new sensor, simply remove the sensor head cap, remove the old sensor assembly and align
the alignment arrows on the new sensor assembly with the sensor head body and press the sensor
assembly toward the sensor head body until it has fully seated in the connector. The sensor board
should be flush with the edge of the sensor head body when fully seated. Reinstall the sensor head cap
and follow the on-screen prompts to upload the sensor settings into the gas detector.
!
Important: Sensor assembly must be fully inserted into the sensor head body when
tightening the sensor head cap. Failure to do so could result in damage to the sensor and/or
the sensor head body.

General Operating Instructions
4.1 Introduction
Swiping a magnetic wand past the Edit key, from any of the Data Display screens, displays the Main
Menu. The Up and Down keys maneuver the selection bar up and down and Edit selects the highlighted
item to enter the sub-menus. All items with a sub-menu are indicated by a right facing arrow at the end
of the line. To edit menu item values, swipe the Edit key, and use the Up and Down keys to edit the
value. Once the desired value is entered, swipe the Edit key again to save the value. Swipe the Next key
to reverse out of a sub-menu.
Important: Some values require a Technician Sequence to be entered to change their
!
values. This is to prevent the operator from inadvertently changing the values. When
prompted to “Enter technician sequence:” simply swipe the Up key four times to unlock the
value for editing.
4.2 General Setup for the SensePoint
After ensuring proper installation perform the following steps:
1. Apply power to the gas detector
2. Verify the detector has begun startup.
Note: Once the detector is on the data screen, you may notice high or low values out of the full-scale
range. These values should quickly return to the zero-gas value if no gas is present. No false alarms
should be indicated at this time as the zero-gas value will be transmitted by the detector during the
user-defined warmup delay period (up to 5 minutes).
3. Using the magnetic interface, navigate the menus to ensure:
a) Alarm levels for Alarm 1, 2 and 3 are set to the desired value
Note: SensePoint gas detectors have standard relays, which should also be set up at this time. When no
relays are installed, alarms are indicated only by the display color.
b) Time and date are set correctly
c) Engineering units are set to the desired value
d) Calibration span gas value is set to the value of the calibration gas that will be used to
perform initial calibration
e) Calibration marker is set to the desired value (this is the value the output will be held at
during calibration and the calibration purge delay)
4. After sensor has stabilized, perform routine sensor calibration in accordance with Chapter 5.

4.3 Normal Operation
During normal operation the sensor data is displayed on one of three data display screens as shown
below. To cycle through the data display screens, use a magnet and swipe the Next key until the desired
screen is reached.
Figure 8 SensePoint Data Display Screens
4.4 Fault Condition
The Fault alarm is used to indicate a condition when there is a failure from the sensor or an out of range
state has been reached. It is recommended to set the fault alarm level to -10% of the span value. For
example, if an H2S sensor is installed with a span value of 100, the fault should be set at -10, or if an
oxygen sensor is installed with a span value of 25, the fault setting should be -2.5.
If relays are installed, the Fault relay is always Failsafe. This is necessary for the relay to de-energize in
the event there is a loss of power, so that a Fault will be indicated.
If relays are not installed, a Fault condition will only be indicated by the display color changing to red
and/or the red Fault LED flashing.

4.5 Alarm Conditions
4.5.1
SensePoint
The SensePoint allows the user to select the color associated with a certain alarm level. Options include
yellow, orange, red, blue and purple. Alarm 1 is always set to yellow, and the Fault alarm is always set to
Red.
Figure 10 SensePoint and SenSmart Alarm Screens
When an alarm level is reached, the display will change to the user defined color and the alarm level will
flash on the display. If Latching is turned on, the alarm will stay enabled until the user acknowledges the
alarm by swiping the magnet over the UP/RESET key, even if the alarm condition has cleared.

Calibration Procedure
5.1 Preparation
Calibration is the most important function for ensuring correct operation of the SensePoint Series of gas
detectors. The CAL MODE is designed to make calibration quick, easy and error free, and a successful
Zero and Span calibration requires only four keystrokes. The 4-20mA output transmits 3mA during the
calibration, and 4mA during calibration purge to prevent alarms. After 5 minutes of inactivity the gas
detector will exit calibration mode automatically.
 RC Systems recommends performing calibrations
 Immediately prior to placing a gas detector in service
 Any time a new sensor is installed
 Every six months for routine calibrations (more often if sensor is known to have been
exposed to gas for extended periods of time)
 Periodic bump tests are recommended if detector has potentially been exposed to
incompatible gases to ensure correct operation
 Follow these calibration guidelines to ensure proper operation of your RC Systems, Inc. gas
detector:
 Calibration accuracy is only as good as the calibration gas accuracy. RC Systems
recommends calibration gases with National Institute of Standards and Technology (NIST)
traceable accuracy to increase the validity of the calibration.
 Do not use gas cylinders beyond their expiration date.
 Calibrate a new sensor before it is put in use.
 Allow the sensor to stabilize before starting calibration.
 Calibrate on a regular schedule. RC Systems recommends once every 6 months, depending
on use and sensor exposure to poisons and contaminants.
 Calibrate only in a clean atmosphere, free of background gas.

Figure 11 Calibration Diagram
Prior to beginning your calibration make sure you have the following items:
1. A cylinder of calibration gas with concentration equal to the SPAN GAS VALUE setting (RC
Systems typically recommends choosing a value at 50% of full scale.)
2. A cylinder of Zero Air (unless you are confident there is no target gas potentially present in
the area)
3. A flow regulator, a fixed flow of 0.5LPM is recommended for most applications, but some
instances may require a 1.0LPM fixed flow regulator.
4. A Splash Guard with integral Calibration Adapter or Calibration Adapter

5.2 Routine Calibration Procedure
Use the following step-by-step procedure to perform Zero and Span calibrations (Figure 13 may be used
for reference to the Menus.):
!
Note: The first three steps must be performed before the timer expires, 15 seconds,
otherwise the SensePoint will exit back to the Data Display Screen.

1. Enter Calibration mode from any of the Data Display Screens by swiping the Down/Cal key.
2. Swipe the Edit key to enter Cal Mode.
3. Apply a clean Zero Gas, using the Calibration Cup or be sure there is no background target
gas in the monitored area. After the reading is stable, swipe the Edit key to set the Zero
Calibration. To skip the Zero calibration, and go to the Span calibration, swipe the Next key.
Once a message that the Zero calibration was completed successfully has been displayed,
proceed to the next step.
4. Apply the correct, as indicated, span gas. After the reading is stable, swipe the Edit key to
set the Span Calibration. To skip the Span Calibration, swipe the Next key. When a message
that the Span Calibration was completed successfully is displayed, the gas detector will exit
back to the Data Display Screen.
5. Remove the calibration gas. Once the Cal Purge Delay has expired, normal alarm and relay
functionality will be restored.
Calibration history records are logged and may be viewed in the Sensor Information.

5.3 Bump Test Procedure
!
Note: A bump test, when performed correctly, is meant to check both sensor and
alarm functionality. This results in expected alarms, and proper precautions should be
taken.
Also known as a functionality test, a bump test is not meant to test the accuracy of the detector, and no
calibration settings are changed during the test.
To perform a bump test, briefly expose the sensor to a gas of known concentration (above the Low
Alarm set point), and check to ensure the display reading increases to a value within tolerance of the
concentration applied and check for alarm actuation. If the sensor does not perform as expected, RC
Systems recommends performing a routine calibration and/or replacing the sensor. If the alarm does
not perform as expected check the detector’s alarm settings.

Chapter 6
Maintenance Procedure
6.1 Regular Maintenance
RC Systems recommends performing calibrations at regular intervals to ensure proper functionality of
the SensePoint. During routine calibration, RC Systems recommends a visual inspection of sensor head,
enclosure and conduit entries to check for cleanliness and physical integrity. Cleaning the detector is
recommended when necessary but be aware that some cleaning compounds may be detected by an
operational detector depending on the sensor type. So, proper precautions should be taken.
RC Systems recommends calibrations:
 Immediately prior to placing a gas detector in service
 Any time a new sensor is installed
 Every six months for routine calibrations (more often if sensor is known to have been
exposed to gas for extended periods of time)
 Periodic bump tests are recommended if detector has potentially been exposed to
incompatible gases to ensure correct operation
6.2 Sensor Replacement
When a sensor has reached its end of life, it is necessary to replace the sensor. For sensor replacement
instructions, refer to Chapter 3.7.

Appendix 3
Modbus Table and Operations
The SensePoint may be equipped with two optional (10-0388 Relay/RS-485 Modbus Option Board) RS485 boards where the 10-0388 Relay board can be set up as master (for remote sensors) or slave, and
the RS-485 Modbus Option board can be set up as master (for remote sensors) and slave (base 1).
The Modbus slave ports allow function code 3 (write coil), as well as function code 6, and 16 (write
holding registers). These function codes can be used to write configuration parameters to the
SensePoints. Writing parameters that span multiple register (such as 32bit floating points) requires
function code 16. All registers must be written at once.
The following table describes the SensePoint Modbus slave database. Any portion of this data may be
read by a Modbus master device such as a PC, PLC, DCS or RC Systems ViewSmart controllers. Since the
Modbus port is RS-485, multiple SensePoints may be multi-dropped onto the same cable.


Setpoint (Alarm 1, 2, 3 and Fault)
Setpoint enters the engineering unit value where the alarm will
trip. It may be negative, and trip when monitored values fall out
of range in this direction.

Latching (Alarm 1, 2, 3)
Setting Latching to YES causes the alarm to remain active even
after the condition is gone, and to reset only when the
UP/RESET key is swiped from a data display.

Trip (Alarm 1, 2, 3)
Set Trip to HIGH to have the alarm trip when the value goes
above the setpoint. Set to LOW to trip when the value falls
below the setpoint.

On Delay (sec) (Alarm 1, 2, 3)
On Delay allows entering a maximum 10 second delay before
this alarm becomes active. This is useful for preventing
spurious alarms by brief spikes beyond the alarm setpoint.

Off Delay (min) (Alarm 1, 2, 3)
Off Delay allows entering a maximum 120-minute delay before
clearing an alarm after the alarm condition is gone. This is
useful for continuing an alarm function, such as operation of an
exhaust fan, for a period of time after the alarm condition
clears.

Deadband % (Alarm 1, 2, 3)
Deadband allows forcing low values to continue to read zero.
This is useful when there are small amounts of background
gases that cause fluctuating readouts above zero. The highest
amount of Deadband allowed is 5%.


Data From (certain menu items only show up depending on the input type)
Source determines the type of sensor installed in the detector. E.g. bridge,
electrochemical, etc.
Remote Sensor set to Yes indicates that the sensor is installed remotely with Remote
sensor option.
Min and Max Raw set the range of the input to the A/D converter. Normally set to
800/4000. Useful when the sensor’s output doesn’t provide a full range signal.
Remote ID is where the Modbus slave’s ID number is entered
Alias is the register number which defines the location of the variable representing the
input value of the Modbus data received through the communication ports
Interface assigns which communication port the Modbus slave is connected to and the
detector will get its data from
Filter (second) sets the number of seconds over which samples are averaged
Byte Order determines WORD and BYTE alignment of data at the remote Modbus
transmitter when sending this 4-byte IEEE floating point values
Polarity determines the polarity of the sensor
Heater Enabled determines if the sensor heater is turned on or off
Heat (degC) is the thermostat setting of the sensor
Set Voltage set’s the voltage being supplied to bridge type sensors
Set Balance adjusts the balance of a catalytic bead sensor and must only be adjusted
with ZERO gas on the sensor.
Set PGA is the adjustment that matches the input signal range to the detectors input
signal conditioning circuits.
Marker used to detect special modes of operation from analog inputs, which some
monitors use to indicate special modes of operation, such as calibration mode
Configure
Tag is a 16-character ASCII field typically used to describe the monitored point by user
tag number or other familiar terminology.
E. Units or engineering units may have up to 10 ASCII characters, and is usually factory
configured based on sensor type.
Zero defines the reading to be displayed when the output is 4mA (0%)
Span defines the reading to be displayed when 20mA (100%) is the output.
Decimal Points sets the resolution of the displayed reading, and may best to zero, one
or two.
Block Negative blocks negative values from being display (Displays 0).
Deadband (%) allows forcing low values to continue to read zero. This is useful when
there are small amounts of background gases that cause fluctuating readouts above
zero. The highest amount of Deadband allowed is 5%. Note: Deadband affects all
outputs as well as the local reading.
Warmup (m) defines the time allotted for sensor warmup. During this time output s will
be held at a zero value and relays will stay in their normal state.
Cal Purge (m) determines the amount of time the transmitter will stay in calibration
mode after calibration is complete as the sensor returns to normal state.
Calibration
Zero Setpoint is set to the zero value.
Span Setpoint is set to the calibration gas value, typically 50% of full scale.
Cal Gain reflects the change made when calibrating.
Gain Offset reflects the change made when calibrating.
Gain Unity is to reset the Gain and Offset back to default (1 and 0 respectively)
Calibrate is used to calibrate sensors.
Temp Comp allows the user to adjust the gain and offset that is applied to sensors to
compensate for temperature drift. Factory supplied sensors are preprogrammed with
these values which are automatically uploaded from the Smart Sensor.

Frequently Asked Questions
How do I perform a calibration?
 To perform a calibration, please refer to Chapter 5. RC Systems recommends performing
calibrations
 Immediately prior to placing a gas detector in service
 Any time a new sensor is installed
 Every six months for routine calibrations (more often if sensor may have been
exposed to gas for extended periods of time)
 Periodic bump tests are recommended if detector has potentially been exposed to
incompatible gases to ensure correct operation
Is there a Quick Start Guide available?
 Yes, visit www.rcsystemsco.com/downloads for a complete list of all of our product materials
available for download.
My SensePoint is not responding to Modbus queries.
 Verify the Slave ID is correct (Appendix 4).
 Verify the Modbus master is polling the correct alias (Appendix 4).
 Verify Modbus wires are connected to the correct terminals (Chapter 3.4).
My SensePoint is responding to gas but the controller is in fault.
 Verify the analog signal wire is connected to the correct terminal at the monitor (Chapter 3.3).
 Verify the analog signal wire is connected to the correct terminal at the controller. For RC
Systems controllers the HI terminal on the analog input board is where the signal wire connects.
