5.3.3 Auxiliary Controller Values
This section contains Property values related to an input signal to the auxiliary port of the actuator. Refer section 3.2.6
for more information on the auxiliary input. NOTE: These values can only be used on actuators within firmware ≥ version 16.
FlowGainFactor
FlowGainThreshold
TimeHold
TimeOutStandBy
AngleHold
This is a positive or negative integer value between “32767” and “1” used to scale the gain
settings. A negative value will enable inverse actuator operation.
32767 to 1 can be thought of as a scale factor from 100% (default) to 0.1% of standard
control gains. eg: a value of 3277 would REDUCE the gains by 90% (suitable for say a 90%
reduction in flow conditions)
When set to “0” it will enable the HOLD and STANDBY features of the actuator.
If set to “-1” will invert the auxiliary signal. “0” is default for standard non-inverted signal.
Time to hold before returning to control. 75 equates to 1 second. eg: 300 = Hold for 4 seconds.
Time to pause before proceeding to StandBy. 75 equates to 1 second.
The angle the actuator will travel to when in HOLD. VALUE = Angle / 360 x 200 x GB
Note: GB is the Gear Box Ratio for the actuator: G1.2 = “74.1” & G1.3 = “61.8”.

Property Name Default Value Enable Value Notes
FlowGainFactor 32767
Integer value between
32767 and 1.
Used as a scaling factor for control Gains.
eg. 32767 = 1, 24575 = 0.75, 16384 = 0.5,
8192 = 0.25 etc.
FlowGainThreshold 0 0 or -1 A negative value will invert the auxiliary signal.

FlowGainFactor 32767
Integer value between
32767 and 1.
Used as a scaling factor for control Gains.
eg. 32767 = 1, 24575 = 0.75, 16384 = 0.5,
8192 = 0.25 etc.
FlowGainThreshold 0 0 or -1 A negative value will invert the auxiliary signal.
TimeHold 0 See note Use any integer value, 75 = 1 second.
TimeoutStandBy 0 See note Use any integer value, 75 = 1 second.
AngleHold
3705 for G1.2
3090 for G1.3
See note
VALUE = Angle / 360 x 200 x GB
GB: G1.2 = 74.1, G1.3 = 61.8
AngleStandBy
3705 for G1.2
3090 for G1.3
See note
VALUE = Angle / 360 x 200 x GB
GB: G1.2 = 74.1, G1.3 = 61.8

FlowGainFactor 32767
-32767
Note: a negative value
is required to inverse
actuator operation.
Used as a scaling factor for control Gains.
eg. 32767 = 1, 24575 = 0.75, 16384 = 0.5,
8192 = 0.25 etc.
FlowGainThreshold 0 0 or -1 A negative value will invert the auxiliary signal.
