Initial Rate and Final Thickness are the main process setpoints for this layer of material.

Keep in mind that the SQC-122c zeroes thickness at the beginning of each layer. It is

not a cumulative value.

Time Setpoint and Thickness Limit are arbitrary values that will activate a relay when

they are reached.

Start mode allows you to have this layer start immediately on completion of the previous

layer, Auto mode. Manual mode waits for a user signal via the front panel, RS-232, or

digital input to start the layer.

Rate Ramps allow the deposition rate to change over time, under PID control. Each

rate ramp has a starting thickness, an elapsed time to ramp to the new rate, and a new

rate setpoint. Each process layer can have up to two rate ramps.
