FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What should be checked before replacing 9907-167 in a turbine panel?
A reliable replacement request includes the installed code, DC supply, field wiring, turbine valve arrangement and saved governor settings.
Can 9907-167 be selected for an AC-powered 505E installation?
Woodward identifies this code as the 18–32 V DC option, not the AC version. The installed supply should match before ordering.
Does 9907-167 control only turbine speed?
The 505E application can include extraction or admission pressure control in addition to turbine speed, depending on its configuration.
Are settings transferred automatically when 9907-167 is exchanged?
We recommend backing up and comparing the installed configuration because settings should not be assumed to transfer automatically.
What installation detail matters when mounting 9907-167?
The standard 505E is flush-mounted in a panel or cabinet; the panel cutout, clearance and wiring route should match.
What information helps Apter Power quote 9907-167 accurately?
The complete nameplate code, supply voltage, turbine application and configuration record help Apter Power prepare an accurate quotation.
