0.1 Mode - Same as 0.0 Mode, except that the setpoint
is locked and can't be changed.
0.2 Mode - Setpoint is locked, plus, the ALARM will acti-
vate and the safety relay will open as follows:
chamber < (setpoint -3) or chamber > (se3)
In order to use this mode of protection, modes 0.0 or 0.1
will have to be used to reach the setpoint temperature.
Once the chamber temperature reaches the setpoint and
is stable, protection mode 0.2 can be set.
Safety Thermostat
As an added safety feature, the incubator has a thermo-
stat in the heater compartment that limits the upper cham-
ber temperature to 65°C in the event that all other con-
trols fail.

PERATION
Note
If the chamber temperature falls out-
side the setpoint by ±3°C, the
ALARM will activate and safety relay
will interrupt power. This mode can
only be used if the door is to remain
shut and other disturbances don't
effect the chamber temperature.
