Auto, Manual and Off Mode

The controller can be put into Auto, Manual or Off
mode
Auto mode is the normal operation where the output
is adjusted automatically by the controller in response
to changes in the measured temperature.
In Auto mode all the alarms and the special functions
(auto tuning, soft start, timer and programmer) are
operative
Manual mode means that the controller output power
is manually set by the operator. The input sensor is
still connected and reading the temperature but the
control loop is 'open'. In Manual mode the Band and
deviation alarm are masked, the auto-tuning timer and
programmer functions are disabled.
In manual mode the MAN beacon will be lit. The
power output can be continuously increased or

Manual mode must be used with care. The
power level must not be set and left at a value that
can damage the process or cause over-heating.
The use of a separate 'over-temperature'
controller is recommended.
Off mode means that the heating and cooling outputs
are turned off. The process alarm and analogue
retransmission outputs will, however, still be active
while Band and deviation alarm will be OFF.
