(ACK) together to
acknowledge the alarm
If the alarm is still present the ALM beacon will light
continuously.
By default alarms are configured as non-latching, de-
energised in alarm. If you require latched alarms,
please refer to the engineering handbook.
4.4.3
Auto, Manual and Off Mode
The controller can be put into Auto, Manual or Off
mode – see next section.
Auto mode
is the normal operation where the output
is adjusted automatically by the controller in response
to changes in the measured temperature.
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 MAN
beacon will be lit. The power output can be increased
or decreased using the
W
or
V
buttons.
!
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 alarm outputs will, however, still
be active.
