Note: InPC is reset to zero when
the input type is changed, or when decimal position is changed in T/C or RT D
ranges. Changing decimal position in current or v oltage r anges will not reset InPC.

99 . In some cases the time constant of the sensor,
or noise could cause the display to jump enough to be unreadable. A setting of 2
is usually sufficient to pro vide enough filter ing for most cases, (2 represents
approximately a 1 second time constant). When the 0.1 degree resolution is
selected this should be increased to 4. If this v alue is set too high, controllability will
suffer.

POL Process Output Low (936): Select -450°F, -260°C, or -1999 counts to 50 degrees or counts
less than POH.
POH Process Output High (936): Select from 50 degrees or counts greater than POL to
+9990°F, +5530°C, or 9990 counts. A voltage output is scalable from 0 to 10 VDC that
represents the Process Variable. To properly scale the output, the values for POL and
POH must be calculated. The simplest example is an output of 0 to 10 VDC from 0 to 200°.
In this example POL=0 and POH=200. To Calculate POL and POH for other ranges use
the following:
K = (Highest desired temperature - Lowest desired temperature) /
(Maximum desired voltage - Minimum desired voltage)
POH = ((10 - Maximum desired voltage) * K) + Highest desired temperature
POL = ((Minimum desired voltage - 0) * K) - Lowest desired temperature
LOrE Local / Remote Status (992): Select LOC or rE. When LOC is selected, the host computer
is advised not to send remote commands. When rE is selected, CFLt=2, and nAt is set
> 0, if the control is not accessed by the host computer in the time set in nAt, the control
will revert to the CFSP.
CFSP Communications Fail Set Point (992): Set to desired value.
Addr Control Address (992): Set from 1 to FF. This number (hexadecimal, base 16) must match
the address number used by the host computer. Viewed only in this menu.
