Description

MCC63

MCC63 for QI(A) MCCB63 for QI(B)
Switch-over time delay required to switch the mode of input 3 from screw RPM to cavity pressure (or vice versa)
before processing data or setting alarms. Units of 0.01 sec.

MCC64

Number of Input Samples for Loss-of-sensor Alarms [29] Range of 0-200. The module monitors sensor inputs for out-of-range
signals. To avoid nuisance alarms caused by electrical noise, enter a non-zero value. When the module detects a number of
consecutive out-of-range input scans (consecutive loss-of-sensor samples) equal to or greater than this value, it sets the
loss-of-sensor alarm. Setting to zero gives no protection against nuisance alarms.

Expert Response Compensation (ERC) Percentage

Word

Description

PKC05

Minimum Cav Press Control ERC Percentage [31]
Although error coding allows range of 00000 to 09999, the module limits it to a minimum of 01000.

PKC06

Minimum Ram Press Control ERC Percentage [31]
Although error coding allows range of 00000 to 09999, the module limits it to a minimum of 01000.

PKC07 - 08

RFU

Unselected Valve Set-output Values

When the module starts the Pack Profile, it:

sets its unselected outputs to the values listed below

ignores the unselected value of the selected output

uses ramp rates PKC17-20 and PKC25-28 to ramp unselected outputs
