Electronics Issues (Cont’d)
The system variable for output
has been modified.
By factory configuration, the analog outputs
(1 & 2) are configured to output based on
H2S Sample 1. Make sure that if they are
modified, that the right system variables are
selected.
Not coming out

Alarms are latched If alarms are latched, they need to be
acknowledged. Go to the display> cycle

Make sure the alarm setpoint values are as
desired and that the analyzer is below (or
above – like temperature setpoint) those
setpoint values.
Sample Conditioning System Issues
Liquid Carried
over in SCS
Sample too wet for current
conditioning sample system.
If a one-time occurrence: Cleaning required
for sample system, refer to "Sample
Conditioning System Cleaning Procedure"
on page 32.
If more than one time occurrence: Sample
conditioning system may need a system for
wet/dirty sample gas (extra filters set as
coalescing, add liquid float stops, etc.).

Regulator not
maintaining 15
psi (erratic H2S
readings)
Problems with the Regulator
(over pressured)
