2-output format
Units: knots Feet/min Feet
Actual: M 101.2 3500 1005 M
Target: 20.0 3000 0
Parameter 13. Pt Mode:
This parameter is accessible in both 2-output and 3-output formats.
The Pt output can be in one of three modes –
Measure (“
M
”), Leak (“
L
”), or Control (“
C
”).
In the Measure mode, the pressure at the Pt output is simply being measured and displayed
as the “Actual” value in the current Pt units. The pressure is not being changed by the 6600.
In this mode, the Pt control-valve inside the 6600 that is used to change the pressure at the Pt
output is pneumatically isolated from the Pt output. In the Measure mode, the Pt “Target”
value is meaningless, since the 6600 is not trying to achieve any specific target value.
The Leak mode is pneumatically identical to the Measure mode. When either Pt, Ps1 or Ps2
outputs is in Leak mode, the screen changes from the Main Operating screen to the Leak
screen. The Leak screen is detailed in section 3.3.
When the Pt output is in the Control mode the 6600 is actually attempting to achieve the Pt
“Target” value. The Pt control-valve inside the 6600 is now connected to the Pt output and is
actually increasing or decreasing the pressure to achieve and maintain the “Target” value.
The sample screen below shows the Pt mode as Measure (“M”). For an explanation of how to
change the Pt mode between Measure, Leak and Control, please refer to section 3.2.4.

Parameter 14. Ps1 Mode: This parameter is accessible in both 2-output and 3-output
formats. The Ps1 output can be in one of three modes –
Measure (“ M ”), Leak (“ L ”), or Control (“ C ”).
In the Measure mode, the pressure at the Ps1 output is simply being measured and displayed
as the “Actual” value in the current Ps1 units. The pressure is not being changed by the 6600.
