Teledyne Analytical Instruments 47
The first line determines whether a span calculation will be performed
for THC. The second line determines whether a span calculation will be
preformed for SMP. The third line allows the user to modify the span
target value for THC calibration. The fourth line allows the user to
modify the span target value for SMP.
The last line commences the span (after the following query:
________________________________________________
Begin Span:
ENTER-YES ESCAPE-NO
________________________________________________
Pressing <Enter> enters the SPAN mode in the SMP phase first.
The first pass in the SMP phase only purges the sample gas from the
column (no span calculation is performed this time around). Then the
THC is span calibrated followed by the second pass of the SMP mode,
where the span calculation is performed. The 4030 goes through all of
these phases, but span values are only adjusted if the user selected YES
in the initial menu for the respective phase.
4.4.11 The Alarms Function
The Model 4030 is equipped with two alarms and a system failure
alarm relay. Each alarm relay has a set of form "C" contacts rated for 3
amperes resistive load at 250 VAC. See Figure in Chapter 3, Installation
and/or the Interconnection Diagram included at the back of this manual
for relay terminal connections. The alarm relay contacts are accessible to
the user from the 50-pin Equipment Interface connector.
The system failure alarm has a fixed configuration described in
Chapter 3 Installation.
The concentration alarms can be configured from the ALARM
function screen as follows:
________________________________________________
-> AL-1 DEFEATED
AL-1 HIGH
AL-1 NON-FAILSAFE
AL-1 NON-LATCHING
