If System can not be aligned or it will not go to a Green/
Clear condition, the emitter’s TEST input may be open.
When this occurs, the receiver Reset indicator is Yellow, all
Zone indicators will be Red or Green, and the system Status
LED will be Red; the 3-digit display will show a numerical value
equal to one less than the total number of beams. For example,
if an array has 50 beams total, the display would show 49. The
emitter’s Status indicator will flash Green. See Section 4.4 and
Figure 5-1. (However, on a 10-beam system only, the Zone 1
indicator will be Green, and all others Red.)
Opening a switch or relay contacts connected to the TEST1 and
TEST2 connections of the emitter, or supplying a voltage of less
than 3V dc to TEST1 only, simulates a Blocked condition, for
testing purposes.
To verify proper operation, measure the voltage between TEST1
(pin 4, black) and dc COM (pin 3, blue) of the emitter:
• I f the voltage is 10 to 30V dc, the emitter should be in Run
• I f the voltage is less than 3V dc, the emitter should be in Test
*Emitter has only 1-digit display. Two-digit codes are displayed sequentially.

mode and beam scanning should be occurring. If not, check
the +24V dc (pin 1, brown) to verify proper supply voltage.
If the supply voltage is not within the rated supply voltage
specifications, correct the supply voltage and recheck emitter
operation. If the supply voltage is correct, Test1 is 10 to 30V
dc and the emitter does not operate properly (RUN mode with
beam scanning). Replace emitter.

mode, replace emitter.

Overview
Emitter Error
This error can occur either due to
excessive electrical noise or due to an
internal failure.
Excessive Noise Error
This error can occur due to excessive
electrical noise.
Error Description
• R eset the emitter by cycling power to the emitter (see Section 4.3.2).
• If the error clears, perform a Daily Checkout procedure (Section 6.3) and if OK,
• If the error continues, check the ground connection (see Section 2.3).
• I f the sensor has a good earth ground connection, check for electrical noise (see
• If the error continues, replace the emitter.

Cause of Error and Appropriate Action
* The 3-digit display will show a numerical value equal to one less than
the total number of beams. For example, if an array has 50 beams total,
the display would show 49.
