    SECTION 2 – INSTALLATION INSTRUCTIONS Introduction Important: This manual describes both the 2-Wire (SenSmart 2000) and the 3-Wire (SenSmart 3000) 4-20mA versions of the ST-48 transmitter. SenSmart 2000 2-Wire versions are only possible if the 10-0232 Display PCB IS THE ONLY PCB IN THE ENCLOSURE. If the 10-0233 I/O Power Supply is installed it is a 3-Wire version.

Input types include Electrochemical toxic / oxygen sensors, catalytic bead combustible sensors, MOS solid-state sensors, as well as various millivolts, volt and 4-20mA inputs. Sensors supplied by the factory include an 8-wire Smart Sensor interface capable of configuration data uploads to the SenSmart 3000.

    SenSmart 3000 User's Manual Document: UM-1003 Revision Level B Mounting the Enclosure The SenSmart 3000 standard enclosure is a cast aluminum explosion-proof (NEMA 7) enclosure as shown in Figure 2-2. Figure 2-2a shows dimensions with the dual local sensor ‘Y’ included. Figure 2-2: SenSmart 3000 Explosion-Proof Housing 0010-1200 “Y”...

  • Page 8: System Design Specifications

    SenSmart 3000 User's Manual Document: UM-1003 Revision Level B supplied with toxic / oxygen SenSmart 3000s not requiring relays, RS-485 Modbus or LCD backlight. The optional bottom 10-0233 I/O Power Supply board generates voltages needed for LCD backlight, relays, RS-485 Modbus and Bridge sensor and is required with any of these I/O functions.

  • Page 9: Field Wiring Installation

    If a 4-20mA output is all that is required for toxic / oxygen measurements (no LCD backlight, alarms or RS-485) the SenSmart 2000 may be used in the 2-wire mode. CAUTION: It is important to understand the receiver, or controller device must supply the loop power in 2-wire 4-20mA modes.
  • Page 10 Route the receiver wires through the conduit entry and connect to TB1. Steering diodes in the SenSmart 2000 2-wire 4-20mA output automatically correct for polarity so positive and negative are interchangeable. Reassemble the SenSmart 2000. Follow the procedures and recommendations in the receiver manual to complete the installation.

    SenSmart 3000 User's Manual Document: UM-1003 Revision Level B Alarms / RS-485 Modbus 10-0234 Option Installation Description: The optional 10-0234 Alarms/RS-485 Modbus board supplies two level alarm relays, a FAULT relay and an RS-485 Modbus RTU slave port (Figure 2-6). This board is “piggybacked” behind the 10-0232 Display Assembly (Figure 2-3).

    SenSmart 3000 User's Manual Document: UM-1003 Revision Level B taken this technology a step further. A tiny memory IC is incorporated into SenSmart 3000 factory supplied Smart sensors allowing them to contain the entire database of SenSmart 3000 parameters onboard the replaceable Smart Sensor assembly (Figure 2-9). This unique Smart Sensor Interface may be used to configure smart sensors and / or SenSmart 3000’s from a PC rather than entering all variables via the magnetic keypad.

    Figure 3-1: Transmitter Configuration Menu 3.1.1 Single / Dual Gas Monitor Configuration SenSmart 2000’s are 2-wire 4-20mA devices and support only one electrochemical sensor. Addition of the 10-0233 Power Supply board (SenSmart 3000LEL) automatically adds the catalytic bead sensor input and dual 4-20mA outputs. If both the O2/TOXIC and LEL/Current menu items are ON, the SenSmart 3000 will function as a dual gas monitor with both sensor inputs and 4-20mA outputs active.

  • Page 24: Temp Compensation

    SenSmart 3000 User's Manual Document: UM-1003 Revision Level B negative values below the Fault set point will still cause the Fault alarm to trip. The 4-20mA output always locks at 4mA when the reading is negative. Temp Compensation allows user to adjust the gain and offset that is applied to sensors to compensate for temperature drift.

  • Page 25: Tx Sensor Life

    SenSmart 3000 User's Manual Document: UM-1003 Revision Level B TX Sensor Life set for YES, causes the SenSmart 3000 4-20mA output to transmit a sensor life value after successful calibrations during the CAL PURGE delay (see section 4.1). Normal operation is the SenSmart 3000 transmits 4mA during the CAL PURGE delay. But with TX Sensor Life = YES it transmits 4mA for the first 10-seconds, then for 5-seconds transmits a value between 4mA and 5mA, with 4mA equal to 0% sensor life and 5mA equal to 100% sensor life (see Figure 5-5).

  • Page 26: Relay Configuration (If Equipped)

    SenSmart 3000 User's Manual Document: UM-1003 Revision Level B Dead-Band has a minimum value of 1% and a maximum value of 10%. It is useful for preventing alarm cycling when the monitored value is hovering around the set point. EXAMPLE: With a range of 0-100 ppm, if Dead-Band equals 5% and the set point is 20 ppm, after tripping at 20 ppm the value must drop below 15 ppm to reset.
