Product Description

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.

Definitions

Term	Definition
Dangerous Failure	Failure which has the potential to put the safety-related system in a hazardous state
Safety-Related System	A system that implements the required safety functions required to achieve or maintain a safe state and is intended to achieve on its own or with other systems the necessary safety integrity for the required safety functions.
Safety Function	Defined function, which is performed by a safety-related system with the aim of achieving or maintaining a safe state for the plant, in respect of a specified hazardous event.
Proof Test	Periodic test performed to detect failures in a safety-related system so that, if necessary, the system can be restored to an "as new" condition or as close as practical to this condition.
MTTR (Mean Time To Restoration)	The average duration required for restoration of operations after a failure.
λsd	Rate of safe detectable failures per one billion hours. For example, if λsd = 3000, then it is estimated that there will be about 3000 safe detectable failures during every one billion hours of operation. For λsd = 3000, this is about one safe detectable failure every 38 years.
λsu	Rate of safe undetectable failures per one billion hours.
λdd	Rate of dangerous detectable failures per one billion hours.
λdu	Rate of dangerous undetectable failures per one billion hours.
HFT	Hardware Fault Tolerance
System Architecture	Specific configuration of hardware and software elements in a system.
PFDAVG (Average Probability of Failure on Demand)	Average Probability of Failure on Demand.
FIT (Failures in Time)	A unit of measurement representing one failure per billion hours. 1,000,000,000 hours is approximately 114,155.25 years.

 

SPECIFICATIONS

Input Power Supply: 22-26 VDC, 120 mA max (approximately 3.5 watts)

Remote Communication: 2 wire RS485 compatible with Modbus RTU protocol.

Flame And Fault Relay Contact Ratings: 1 A, 30 VDC (Resistive).

Maximum load current of 1A must be de-rated at temperatures higher than 50C ambient according to 1%/C, or 10mA/C. For example, the maximum current at 70C = 1A - (20C x 10mA) = 0.8A.

User Selectable Analog Output: 0-20 mA and 4-20 mA; 500 Ohm Load Max

File Select Input logic high: 21VDC min

File Select Input logic low: 16VDC max

User Interface: Capacitive TouchWheel with LED Display

Ambient temperature: -40 to 70 ºC (-40 to 158 ºF)

Enclosure: IP66

Weight: 2.8 kg (6.1 lbs)

Physical Dimensions: Diameter: 11.7 cm (4.6 inches)

Length: 15.5 cm (6.1 inches)

Finish: Silicone free powder coated

Mounting/Process Connection: 1" NPT female

Pipe Fit Models (PF version): 3/4" NPT

Fuses: Automatically resettable for power source and Flame Relay.

Maximum furnace back pressure: 35 Kg/Cm2 (500 PSI)

Selectable Flame Failure Response Time (FFRT): 1, 2, 3 seconds, Error= +0.0sec, -0.5sec.

Internal Temperature Indication: Degrees C or F in display menu of U2, or available at Modbus register 40019.

Self-Checking

Internal electronic self checking is performed once per second, to verify that system is operating properly. If self check detects an error, the flame relay, and self check relays will open, and the device will display "lockout". This lockout may only be cleared by manual entry reset at the U2 Touchwheel interface.
