ABB SC610 OCS processor input and output unit
The user is responsible for ensuring a quality electrical supply to the equipment. Natural lightning strikes, fast high voltage transients, low voltage
conditions, or an unstable line voltage frequency may cause instrument performance degradation, function loss, or damage to the equipment. The
manufacturer recommends that the installation include a suitable surge suppressor to protect the equipment, and that the user provide an instrument grade
supply power that is free from potential electrical supply problems.
- Warning - the neutral and ground (earth) connections to the equipment must be at earth (0 volts) potential. Failure to maintain earth (0 volts) potential at
these connection points constitutes a serious safety hazard.
- Caution – it is the responsibility of the user to ensure that all connections to the equipment are approved for area classification, that all field wiring,
including signal wiring, has proper separation or insulation rated at 300V minimum to protect the conductors from potentially higher voltages, and that
equipment is securely fastened to protective earth.
- Caution – installation must ensure adequate protection from potential overpressures of supply gas. Severe damage to the equipment, property or injury
to personnel may result if the equipment is exposed to pressures greater than 200 psi (13.78 bar). Protection against pressure regulator bleed through, or
regulator failure, is an absolute requirement for safe operation.
No equipment vent should connect to a collection header without engineering review. Proper installation of equipment requires consideration of possible
ingress of toxic or hazardous materials into the analyzer or shelter via a sample system stream select valve. A failure in an air-operated manifold style
stream select valve can allow sample to flow into the air lines connected to the stream select solenoids internal to the analyzer, thus contaminating the
solenoid vent and causing damage to the solenoid valve.
Red plastic plugs are threaded in to all unused conduit hubs to protect the enclosure from debris during shipping and storage. These plugs are for
temporary use only and are not intended for normal operation. The installer’s responsibility is to remove all plastic plugs and then close each hub with
rigid conduit, cable gland, or plug that is suitable for the area classification.
The equipment is not susceptible to radio frequency when properly installed in a Class A industrial environment. All interconnect devices must be
properly grounded and their interconnect cables must be shielded and terminated at the entry point of the equipment. Assurance of electromagnetic
compatibility for the complete system is by isolating the equipment from all interconnected devices with a recommended minimum distance of three
meters.
Zone 1 only: Intrinsic safety circuit of purge control device is 200 nF capacitance maximum / 1 mH inductance maximum.
Recorder jacks are not to be used unless area is known to be non-hazardous.

Warning – this equipment is air purged. Enclosure shall not be opened unless the area is known to be non-hazardous, free of any flammable materials, or
unless all devices within the enclosure have been de-energized. Power shall not be restored after enclosure has been opened, or after switching off
overpressure, until enclosure has been purged for either 5.46 minutes @ 50 Hz or 4.55 minutes @ 60 Hz at the flow rate noted.
-Warning (PGC2009) – this equipment is air purged. Enclosure shall not be opened unless the area is known to be non-hazardous, free of any flammable
materials, or unless all devices within the enclosure have been de-energized. Power shall not be restored after enclosure has been opened, or after
switching off overpressure, until enclosure has been purged for either 10.90 minutes @ 50 Hz or 9.10 minutes @ 60 Hz at the flow rate noted.
The user is responsible for ensuring a reliable supply of protective gas, which is required for the purging system. In the event of purge / pressurization
failure, normal electrical potential within the enclosure will remain non-incendive; however, their electrical circuits may not be intrinsically safe. The
purge control device, therefore, provides an alarm contact to monitor the purge / pressurization status and to alert the user of a failure. Such a failure may
require the isolation of remaining hazardous live circuits to ensure a safe area.
- Warning - do not open any enclosure in the presence of an explosive atmosphere; do not open any flameproof enclosure while energized.
Type PGC2007 and PGC2009 with T3 marking: the internal liquid sample valve may be factory set to operate at a temperature above the external area
temperature code. The user’s responsibility is to examine the equipment label for a possible wait time before opening the pressurized enclosure: enclosure
shall not be opened unless the area is known to be non-hazardous, or unless all devices within the enclosure have been de-energized for 30-minutes.
Equipment includes Ex components as described in the repair section of the operation and service manual.
Any modification affecting the essential health and safety requirements of the equipment, or the integrity of a type protection, shall be defined as
substantial. It is the responsibility of the person conducting such modification to ensure a unit verification and approval by a Notified Body.

Il incombe à l’utilisateur de s'assurer que les conditions spéciales pour une
utilisation sûre sont satisfaites :
L’utilisateur a la responsabilité d'assurer une alimentation électrique de qualité à l'appareil. Des impacts de foudre, des phénomènes transitoires rapides,
des conditions de faible tension ou une fréquence de tension de secteur instable peuvent causer une dégradation de rendement de l’instrument, une perte de
fonctionnement ou des dommages à l'appareil. Le fabricant recommande la pose d’un limiteur de surtension approprié pour protéger l'appareil. De plus,
l’utilisateur doit assurer une alimentation électrique de classe instrument exempte de perturbations.
- Avertissement - les connexions du neutre et de la masse (terre) à l'appareil doivent présenter une différence de potentiel de terre de 0 volt. Le fait de ne
pas maintenir un potentiel de terre de 0 volt à ces points de connexion présente un danger grave pour la sécurité.
- Attention – il est de la responsabilité de l’utilisateur de s’assurer que tous les raccordements de l'appareil sont approuvés pour la classification de zone,
que le câblage du site, y compris le câblage de signal, présente une séparation ou une isolation nominale d'au moins 300 V pour protéger les conducteurs
contre les hautes tensions et que l'appareil est correctement raccordé à la terre.
- Attention – l’installation doit assurer une protection adéquate contre une surpression possible du gaz d’alimentation. L'appareil ou les biens peuvent être
gravement endommagés et le personnel risque d’être blessé si l'appareil est exposé à une pression supérieure à 200 psi (13,78 bar). Le régulateur de
pression doit être absolument protégé contre toute infiltration ou défaillance pour assurer un fonctionnement sécuritaire.
Aucun évent de l'appareil ne doit être raccordé à un collecteur sans être soumis à une analyse technique. Pour bien installer l'appareil, il faut tenir compte
de l’infiltration possible de matière toxique ou dangereuse dans l’analyseur ou l’abri en passant par la vanne de sélection de voie du système
d’échantillonnage. Une défaillance de la vanne de sélection de voie (collecteur à commande pneumatique) risque de laisser l’échantillon circuler dans les
