Digital Temperature
Knowing Your Temperature Controller
PV: This upper display indicates the
actual Process Value (or current
temperature) of the bath and cannot
be changed manually.
SV: The lower display indicates the
Set Value or desired bath
temperature. This Set Value is
adjustable.
ALM 1: If this light is on, it means
that the machine is currently heating.
It will shut off once the desired
temperature has been reached.
OUT: If this light is on, it means that
the bath temperature is out of the
preset range of 50
˚F - 160˚F. There
is a 5
˚ hysteresis which means that
the heating mechanism (and the
OUT light) will go on/off based on a
5
˚ variance. This protects the life of
the motor contactor.
AT, ALM 2: Omegasonics use only.
