Expert Response Compensation (ERC) Percentage

Word

Description

SCC05

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

SCC06

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

Watchdog Timer

Word

Description

SCC08

Profile Watchdog Timer Preset [21] When the module starts the Second Clamp Close Profile, it

S

starts an internal Profile Watchdog timer

S

stops this timer and resets its accumulated value to zero (after reporting total execution time in CPS58) when it completes the

profile

S

sets master status bit SYS04-B01 when the accumulated value of this timer equals or exceeds this entry

A zero entry inhibits SYS04-B01.

Unselected Valve Set-output Values

When the module starts the Second Clamp Close Profile, it:

sets its unselected outputs to the values listed below

ignores the unselected value of the selected output

uses ramp rates SCC17 - SCC32 to ramp unselected outputs

Word

Description

SCC09

Output #1 Set-output Value during Profile [19]

SCC10

Output #2 Set-output Value during Profile [19]

SCC11

Output #3 Set-output Value during Profile [19]

SCC12

Output #4 Set-output Value during Profile [19]

SCC13

Output #5 Set-output Value during Profile [19]

SCC14

Output #6 Set-output Value during Profile [19]

SCC15

Output #7 Set-output Value during Profile [19]

SCC16

Output #8 Set-output Value during Profile [19]
