WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to serious
injury or death. This device does NOT include the self-checking redundant circuitry necessary to allow its

use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de­energized sensor output condition.

Overview

VALU-BEAM SMI912 Series sensors are designed for intrinsically safe operation in hazardous atmospheres. They are certified by Facto­ry Mutual Research, CSA, and KEMA as being intrinsically safe when used with approved intrinsic safety barriers.

SMI912 Series sensors may be wired for either two- or three-wire current-sinking operation. In the three-wire hookup, which requires two
intrinsic-safety barriers, the sink current is 15 mA. The two-wire hookup, which requires one barrier, sinks ≤ 10 mA (OFF state) and ≥ 20
mA (ON state).

SMI912 Series sensors feature rugged, encapsulated construction, along with adjustable sensitivity and switchable light or dark operate.
They also include Banner's exclusive Alignment Indicating Device system, which lights an indicator LED whenever the sensor “sees” its
modulated light source, and pulses at a rate proportional to the received light signal strength.

Intrinsic safety barriers and current trip point amplifier model CI3RC2 are also available (see Accessories).

Installation Notes

WARNING: Explosion Hazard

Do not disconnect equipment unless power has been switched off or the area is known to be non-hazard­ous.

FM Installation

1. Barriers must be installed in accordance with manufacturer's instructions.

2. Barrier entity parameters must meet the following requirements:

2 www.bannerengineering.com - tel: [phone] P/N 03396 Rev. K

VALU-BEAM SMI912 Series

• Voc or Vt ≤ Vmax Ca ≥ Ci + Ccable

• Isc or It ≤ I max La ≥ Li + Lcable

3. Maximum non-hazardous area voltage must not exceed 250V.

4. For guidance on installation, see ANSI/ISA RP12.6, “Installation of Intrinsically Safe Instrument Systems for Hazardous (Classified)
Locations.”

5. The sensors are suitable for installation without barriers in Class I Div. 2 Groups A, B, C, D; Class II Div. 2 Group G; and Class III Div.
2, when installed in (or through the wall of) a suitable enclosure with provision for connection of rigid metal conduit per the National
Electrical Code, as acceptable to the local inspection authority having jurisdiction.

CSA Installation

1. Barriers must be installed in accordance with manufacturer's instructions.

2. Barrier entity parameters must meet the following requirements:

• Voc ≤ Vmax Ca ≥ Ci + Ccable

• Isc ≤ I max La ≥ Li + Lcable

3. Maximum non-hazardous area voltage must not exceed 250V.

4. Install in accordance with Canadian Electrical Code, Part I.

5. The sensors are suitable for installation without barriers in Class I Div. 2 Groups A, B, C, D when installed in (or through the wall of) a
suitable enclosure with provision for connection of rigid metal conduit per the Canadian Electrical Code, as acceptable to the local inspec­tion authority having jurisdiction.

Specifications

Supply Voltage and Current

Sensor only: requires 10 to 30V dc, 25 mA maximum
Division 1 use (with barriers): requires a minimum sys-

tem supply voltage of 10 volts (see hookup information
and hookup diagrams).

Sensing Beam

Infrared (880 nm) or visible red (650 nm), depending
on model

Adjustments

Light/Dark Operate select switch on rear of sensor
Sensitivity control on rear of sensor allows precise gain

setting (turn clockwise to increase gain)
