Word 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.
Bit-mapped Control Words
Word Bit Description
PKC01 Block ID = 00001010 (Low byte). High byte reserved for the module. Do not use.
PKC02 Configuration Selections
B00-B02 Selected Cavity Pressure Control Valve
The module uses its algorithm to drive the following output during any Cav Press/Time Pack Profile.
B02 B01 B00
0 0 0 Output #1
0 0 1 Output #2
0 1 0 Output #3
0 1 1 Output #4
1 x x Invalid
B03 Cavity Pressure Algorithm Selection
= 0 Dependent Gains (ISA)
= 1 Independent Gains (A-B)
B04-06 Selected Ram (Screw) Pressure Control Valve
The module uses its algorithm to drive the following output during any Ram Press/Time Pack Profile.
B06 B05 B04
0 0 0 Output #1
0 0 1 Output #2
0 1 0 Output #3
0 1 1 Output #4
1 x x Invalid
B07 Ram (Screw) Pressure Algorithm Selection
= 0 Dependent Gains (ISA)
= 1 Independent Gains (A-B)
B08-15 RFU
PKC03 - 04 RFU
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
