Reverse pumping using trigger function with volume not permitted

[pe2269]

Hi,
I want to dispense a volume of solution with an Atlas scientific pump in both directions of rotation.
I use the trigger duration function with the Output: Volume to do that.
But when i want to indicate a reverse direction of rotation with a negative volume i obtain the error :
error : Volume must be a positive value.
Whereas in the output of my pump i must indicate a negative volume to have an inverse direction of rotation.
thanks for your help

I resolved the problem with a custom Output : Volume that accept negative values

Sorry for the delay. This is a good fix to the issue. I'll commit the change to the Volume Output Action that will be incorporated into the next release.
