    Model S4100C Installation WARNING - Installation and Maintenance must be carried out by suitably skilled and competent personnel only. On Receipt of your Equipment All instruments shipped by General Monitors are pre-packed in stout containers and enclosed in a shock absorbing filling which affords a considerable degree of protection against physical damage.

  • Page 12: Sensor Poisons

    Model S4100C • Observe the ambient temperature limitations quoted in the specification. If a sampling preconditioning system is employed, take steps to ensure that vapours will not condense in the associated pipework. • The mounting should be as free from shock and vibration as possible. Avoid mounting Smart Transmitters directly on structures or process equipment prone to high levels of vibration or shock.

  • Page 13: Interconnecting Cable Guidelines

    Model S4100C Interconnecting cable Guidelines • The Smart Transmitter requires an interconnecting cable with an overall screen (shield) and armour. Cables to BS5308 Part 2, Type 2 or equivalent are suitable. • Interconnecting cables should be segregated from power and other “noisy” cables.

  • Page 24: Calibration

    Model S4100C Calibration Calibration may be carried out as follows: • Ensure that the instrument has stabilised for at least 1 hour and that there is no combustible gas present at the sensor. If the background levels of gas are suspected, their presence may be confirmed by capping the sensor and observing a fault in indicated gas concentration as the sensor oxidises the entrapped gas.

  • Page 25: New Sensor Calibration

    Model S4100C New Sensor Calibration New sensor calibration may be carried out as follows: • Ensure that the instrument has stabilised for at least 1 hour and that there is no combustible gas present at the sensor. If the background levels of gas are suspected, their presence may be confirmed by capping the sensor and observing a fault in indicated gas concentration as the sensor oxidises the entrapped gas.

  • Page 26: Calibration Check

    Model S4100C Calibration Check • Place the magnet on the General Monitors Logo on the Nameplate. The instrument will display “ - - -“ for 5 seconds and then enter the menu routine. Remove the magnet. Select “CCA” by briefly reapplying the magnet when the display scrolls around.

  • Page 27: Special Power Up Routine

    Model S4100C Special Power up Routine If the instrument is powered up with the magnet present it will display “EEPROM write activity” for 1 second, followed by “Power up in progress” as above. The magnet present will cause the Modbus Parameters to be reset to factory default. The magnet may be removed immediately.

  • Page 28: Maintenance

    Model S4100C Maintenance WARNING - Installation and Maintenance must be carried out by suitably skilled and competent personnel only. Maintenance Once correctly installed, systems require very little maintenance other than Routine Re-calibration (see section 4) and periodic inspection. Sensors exposed to the elements may require a little grease on the accessory mounting threads.

  • Page 29: Trouble Shooting

    Model S4100C Trouble Shooting Fault codes and Remedies Faults are stacked according to priority, i.e.: if more than one Fault exists at a particular time, the display will show the Fault with the highest priority (lowest number in priority column). As the Faults are being cleared, the Fault with the next highest priority will be displayed, until all Faults have been cleared.

  • Page 30: Alarms

    Model S4100C Alarms Alarms are stacked below Faults according to priority i.e.: if a Fault and (latched) Alarm(s) exist at a particular time, the display will show the Fault. As the Fault is cleared, the Alarm with the next highest priority will be displayed. Latched Alarms may be cleared by briefly applying the magnet to the General Monitors Logo on the Nameplate if the Alarm condition no longer exists.
