Operating Modes
Protocol has three primary modes of operation: the Manual mode, the Timer mode and
the Program mode.
Manual Mode
The Manual mode is a single setpoint control mode that controls the process at the user
specified setpoint for an indefinite period of time. The Manual mode controls the oven
temperature within close limits as specified by the PID tuning parameters.
Timer Mode
The Timer mode is a single setpoint control mode with a built-in process timer that
starts timing either at the beginning of the process or at a user specified temperature.
As in the Manual mode, the Timer mode uses the PID parameters set in the tune mode.
Program Mode
The Program mode is a programmable ramp and soak control consisting of up to eight
profiles. Each profile consists of up to six segments for a total of 48 segments (8 x 6 =
48). Any one profile may be run recursively from two to 99 cycles or even continuously
if it is desired.
Each segment consists of a ramp and soak period. During the ramp period, the control
will track oven temperature. For example, a ramp is entered to heat from 100E C to
150E C in 50 minutes. Protocol will track the temperature 1E C every minute for 50
minutes. During the soak period, temperature is maintained as specified by the tuning
and soak deviation parameters.
Protocol will not allow a soak time to begin until the actual oven temperature is within
the soak deviation limit. This process is called assured soak. The ramp and soak
periods are adjustable from 0 to 99 hours, 59 minutes. Within each ramp and soak
period, up to three event outputs can be programmed either on or off.
The event relay is used for factory installed modifications, then disconnected before
shipping. Please consult the factory for information on connecting the event outputs.
When the events are connected, the user has the capability of controlling relays,
solenoid valves, etc., throughout the programming cycle.
