Expert Response Compensation (ERC) Percentage

Word

Description

INC05

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

INC06

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

Unselected Valve Set-output Values

When the module starts the Injection Profile, it:

sets its unselected outputs to the values listed below

ignores the unselected value of the selected output

uses ramp rates INC17 - INC32 to ramp unselected outputs

Word

Description

INC09

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

INC10

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

INC11

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

INC12

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

INC13

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

INC14

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

INC15

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

INC16

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

Output Ramp Rates

The module uses the following ramp rates when moving its outputs
from setpoint to setpoint during the Injection Profile. The module
interprets a ramp rate of zero as a step function ramp (ramp disable).
