  • Page 5: General Description

    The LCD of the SensAlert IR displays the gas concentration(s) and sensor status(s). The SensAlert IR has one (1) “Alarm” LED and one (1) “Status” LED. The SensAlert IR also has three (3) magnetic switches located around the circumference of the unit. This manual will describe the operation and use of the SensAlert IR Transmitter.

  • Page 6: Mechanical

    SensAlert IR Transmitter Environmental: The SensAlert IR Dual Transmitter can be installed in indoor, outdoor, and wet locations. The housings have ingress protection ratings of IP66. Pollution degree 2 and Overvoltage category II Operating Temperature (Ta) and Humidity Rating: -40° to +40°C (-40 to +104° F) when equipped with the optional LCD heater 0°...

  • Page 7: Electrical

    4-20 mA (Source Type), max 1000 ohm load at 24 Vdc supply voltage. The 4-20 mA output is provided by the sensor and is passed through the SensAlert IR Transmitter. The transmitter can be located at any point in the sensor’s output loop. Consult the appropriate sensor manual for 4-20 installation requirements.

  • Page 8: Unit Installation

    When installing, make sure power is off when connecting the sensor, field, and relay wiring to the appropriate terminal blocks. DO NOT turn the power back on until the SensAlert IR is secured to the housing using all four hex head screws.

  • Page 9: Power Supply

    For hazardous location installations seals must be installed within 18 inches of conduit entries. The SensAlert IR Transmitter has three (3) ¾” NPT threaded ports for mounting and wiring the sensor(s) and transmitter into a permanent installation. All ¾ NPT threads must pass L1 thread/plug gauge.

  • Page 10: Optional Features

    6.2. Data Card Option The Data Card Option of the SensAlert IR uses a MMC card to log different events to help track and changes or sensor behavior. See below for events that get logged: Gas Change Events- When a gas level rises or falls according to a pre-determined delta (change) threshold, a gas record is entered into the log by the SensAlert IR, containing the timestamp and gas level at the time of the event.

  • Page 12: User Interface

    7. USER INTERFACE User Inputs – Magnetic Switches: The SensAlert IR Transmitter has three (3) magnetic switch pickups on the Display PCA. The picture below shows the locations of the magnetic switches labeled UP, DOWN and ENTER. Placing a magnet near one of the switches will cause the following operations to occur.

  • Page 13: Initial Startup

    At the end of the warm-up period with no faults present, the SensAlert IR Transmitter automatically enters the normal operating mode.

  • Page 15: Normal Operation

    The 4-20 mA output ports of the SensAlert IR are non-isolated current source(s), passed through from the attached sensor(s). Their output values are defined by the associated sensor manual(s) (4 – 20 mA normal gas levels, less than (<) 4 mA indicates a status condition such as warm-up, calibration, or a sensor fault).

  • Page 16: Setup - Configuration Operation

    SETUP – CONFIGURATION OPERATION Once the SensAlert IR is powered up it may have to be configured to run correctly based on the system in which it is intended to be operated. For example, it will have to be set up based on whether it has one or two sensors attached, how the alarm relays are intended to operate and the network settings and ID will have to be set for the Modbus communication.

    Use caution when applying ON DELAY to the activation of alarm relays as an unsafe atmosphere may be present for up to 255 seconds prior to any alarms being activated. Sensidyne Document No. 360-2001-02 (Rev A)
  • Page 20 Relay Menu. Logic: A key feature in the SensAlert IR Transmitter is the Sensor Role because only one set of relays is provided to service both attached sensors. Therefore, in determining the sensor mode, a decision regarding how the relays will be used must be considered and a decision concerning what relay mode is used must be made.
  • Page 21 Identical Sensor Role and should be set PRIOR to setting the Identical Sensor Role. The fault relay will engage if EITHER sensor is reporting a fault condition, or if the SensAlert IR Transmitter is in a fault state. CAUTION: AND or SENSOR TWO relay logic must not be used when the sensor mode is SINGLE.

  • Page 23 SensAlert IR Transmitter The sensor mode in which the SensAlert IR Transmitter operates is chosen by the user and is a key decision that must be made before deploying or changing the sensing/monitoring plan. The choice will be determined by how many sensors are deployed, what gases are measured and how that data is captured.

    The SensAlert IR Transmitter can speak to various devices that communicate using standard 16-bit Modbus. (For more details, see the SensAlert IR Transmitter 16-bit Modbus Technical Sheet) Based on the Modbus register address and function code combinations provided in queries to the Transmitter by a Modbus Master, it can distinguish which HMI protocol is appropriate.
