2. Connect load(s) in series with transmitter and power
supply.
NOTE:
Connecting the transmitter output to some types
of computers may cause the computer display
reading to fluctuate. This is caused by “electrical
noise” in the signal line. To correct this condition,
connect a 4.7 microfarad/80 volt, metal foil ca-
pacitor across the computer input.
All Model 692P regulatory agency certifications for installa-
tion in a hazardous area require that the transmitter must
be:
n
Powered by a power supply that provides no more than
28 volts DC.
n
Powered through a Pepperl & Fuchs KHD3-ICR/Ex130
200 transformer isolated barrier (GLI p/n 1F1054).
Furthermore, each respective regulatory agency requires
that you meet additional specific conditions. Refer to the
appropriate agency subheading for details.
The 692P is UL Classified as intrinsically safe in a Class I
or II, Div. 1 hazardous area (Groups A through G) only
when:
1. Using a GLI pH sensor with a model number listed on
GLI control drawing 1001X4N1138.
2. Wiring the system in accordance with GLI control draw-
ing 1001X4N1138.
The 692P is CSA Certified as intrinsically safe in a Class I
or II, Div. 1 hazardous area (Groups A through G) only
when:
1. Using a GLI pH sensor with a model number listed on
GLI control drawing 1001X4N1179.
2. Wiring the system in accordance with GLI control draw-
ing 1001X4N1179.
