VI. Zone temperature
is not stable.

Check For:

A. Thermodynamics

1. If the set points of adjacent zones differ by more than about 30

degrees C, the heat zone with the lower set point may in fact
be heated by the other heat zone, thus causing an over-
temperature condition. This condition may be corrected by
adjusting the set points of the zones in question. If the
customer needs zone separation greater than 30 deg then
please contact the factory for support.

B. Thermocouple/SSR

1. Choose Plot Setup from the Utilities menu. Configure the plot

to show the set point, output %, and process variable for the
zone in question. (

See

Operating System Software Guide,

section C-4d

) Then choose Channel Trend Plot from Window

menu. A typical trend plot is shown in

figure 10

.

Figure 10

2. Examine the plots on the screen. If the PV (Process Value) curve

is very erratic, as shown in

figure 11

, suspect a faulty

thermocouple that is shorted to earth ground. Verify this by
disconnecting the suspected thermocouple from the controller and
checking for continuity between each wire and ground by using a
multi-meter set to the ohms scale. Perform this test with the
thermocouple both hot and cold. If continuity to earth ground
exists, replace the thermocouple. (
