This is only fitted when the overtemperature option is ordered. To identify whether it is fitted,
observe the controller panel: if it is fitted the overtemperature key and warning light are present.
The overtemperature key must be held depressed continuously while viewing or adjusting the
overtemperature controller. If the Overtemperature key is released, the display reverts to the main
controller.
Note: on the 201 display the letters
m
and
w
look like
n
and
u
. In these
instructions the letters are described
as m and w.
With the key pressed the overtemperature setpoint is normally displayed. To alter the value, use
Down and Up. To view the measured temperature, press Scroll until
PV
(process variable) is
displayed, then press Down or Up. Keep the overtemperature key depressed during these
operations.
When an overtemperature condition is reached, the overtemperature warning light changes from
green to flashing red. To “accept” or “reset” this alarm condition, press the Overtemperature key
and the Page key together; the warning light changes to continuous red. Once the overtemperature
condition is cleared (by the temperature falling), the light changes to green and normal operation
resumes.
