DCP200 Profile Controller & Recorder - Product Manual

The Auto-Hold Feature

Each profile segment has individual Auto-Hold settings. If utilised, these ensure that the profile and the actual process remain synchronised. If the process does not closely match the required setpoint by remaining within the defined Hold Band, the profile can be held until it returns within bounds.

The user can choose to hold the profile if the process goes beyond the Hold Band Above The Setpoint only, Below The Setpoint only or to Band (either side of the setpoint). When Auto-Hold becomes active, the profile status is shown as “Held”.

During a Dwell, the dwell time is increase by the time that the process is outside of the hold band in the selected direction(s). This ensures the process was at the desired level for the required amount of time.
