CONTROL PANEL OVERVIEW
4.1 Power Switch: The main power I/O (on/off) switch controls all power to
the unit and must be in the I/ON position before any systems are
operational.
4.2 High Limit Safety Thermostat: The High Limit Safety is an independent
temperature control that must be adjusted by a flat-head screw driver. It
prevents temperature runaway in the event that the Main Temperature
controller fails. If the chamber temperature rises above the Main
Temperature set point, the High Limit maintains temperature at its own set
point, preventing sample loss or unit degradation. Please note that it is
not recommended that the unit be allowed to operate using only the High
Limit to control temperature as temperature uniformity will suffer.
4.3 High Limit Activated: This pilot light is on when the High limit has been
activated and has taken control of the heating element. Under normal
operating conditions this pilot lamp should never be on.
4.4 Main Temperature Controller: This is a microprocessor based
Temperature/Time Control with ramp and soaks capabilities (Watlow
model 981).
4.5 Power Exhaust Outlet: The Power Exhaust outlet is controlled by the
Main Temperature Controller. It is located at the back of the unit next to
the power cord.
