GENERAL INFORMATION

The Honeywell U2-101xS series model is a viewing head and signal processor in a single enclosure intended for use with a burner control system in Industrial Flame Monitoring applications. There are several options available (see Table 1 on page 2). Each model includes one, two, or all three sensors, and can be ordered with quick disconnect (non-PF Models DIV2,ZN2) or pigtail external connection method (PF Models DIV1,ZN1).

Each sensor operates independently from another, allowing adjustment of each sensor.

IMPORTANT

Flame monitoring systems are safety systems.

Please read this manual carefully and completely before installation and before attempting adjustments.

Only qualified personnel familiar with Flame Safety System should carry out installation and configuration.

U2 is certified to be used in prescribed manner.

Any modification or inappropriate installation or operation may result in unsafe operation and will void implied or expressed warranty.

! CAUTION

Possible Equipment Damage

The aluminum surface of the U2 may store an electrostatic charge and become a source of ignition in applications with a low (<30%) relative humidity. Cleaning the surface should only be done with a damp cloth.

! CAUTION

Do not expose to acetone, gasoline, hexane, or ethyl acetate. label is not approved for these chemicals.

INSTALLATION

See “Typical Installation Diagram.” on page 12.

Installation should be carried out by a qualified engineer and should meet all local standards and safety requirements.

Hazardous location installations require the use of ITC/CIC approved cable installed in cable tray for non-PF models, and in metal conduit for -PF models. The cable installation must conform to the latest revision of the National Electrical Code, or Canadian Electrical Code for Class I, Division 2 (non-PF models), or for Class I, Division 1 (-PF models).

WARNINGI

Approved CLI, DIV1 conduit seal must be installed at PF model enclosure fitting for CLI, DIV1 hazardous location use.

Non-PF models must be secured as follows: hand-tighten the connector at viewing head until it can be turned no more. Continue tightening the connector an additional 180 degrees using pliers, or similar tool. Verify that connector cannot be loosened by hand.

WARNINGI

Over-tightening the connector can damage the connector or housing.

Damage will void warranty and hazardous location approvals. Do not exceed 180 degrees of further rotation after hand tightening!

U2-S MODEL COMBINATION VIEWING HEAD AND SIGNAL PROCESSOR

WARNINGI

EXPLOSION HAZARD

DO NOT DISCONNECT WHILE CIRCUIT IS LIVE UNLESS AREA IS KNOWN TO BE NONHAZARDOUS.

Substitution of components may impair suitability for class i, division 2.

The U2-S model viewing port is designed for interface to a 1" NPT (M) fitting. The viewing head can be mounted in any orientation, any angle, upward or downwards.

It is recommended that earth ground is applied at the labeled earth ground screw connection on the housing. It is recommended the drain wire be connected to earth at power supply.

To reduce noise interference from ignition transformer or other high voltage sources, make sure all high voltage cables are in good condition and are at least 300 mm (12") away from U2 wiring.

Location/Mounting on Burner

Honeywell can provide mounting accessories such as a swivel mount, heat/electrical insulator, quick mechanical disconnect, high pressure isolation unit, etc. Check with your sales representative for your application.

1.Ensure location provides clear view of the flame under all operating conditions.

2.If the burner is provided with a pipe mount, use a bell type reducer to 1" NPT (M).

3.When using purge/cooling air, make sure hoses are electrically isolated from the Earth to prevent multiple ground loops.

4.Depending upon the application, purge/cooling air pressure and flow will be different. As it is easier to measure pressure than flow, ensure that the entrance to air connection is a minimum of 25 mm WC (1" wc) above back pressure at all the time, from minimum to maximum load.

5.IMPORTANT!

FLAME DISCRIMINATION

In multi-burner applications, it is important to sight for high frequency, high radiation intensity zone of the target flame, while sighting the low frequency, low radiation intensity zone of the background flame see Fig. 3 for IR, or Fig. 4 for UV for an example. This allows for filter, gain, and threshold settings to properly discriminate or recognize the target flame while rejecting background flame.

6.Where practical, use a swivel mount to allow for adjustments to optimize the flame viewing location.
