Observed Field Condition
13) “The Hunter ICC controller runs every station for about 3 seconds, then moves onto
the next station until all stations have operated. This occurs in both manual operation
of a single station or during a scheduled start time”.
Possible Causes
This is commonly a sign that the Hunter ICC motherboard is failing and it requires
replacement.
How to Troubleshoot
If you have access to another Hunter ICC controller, swap the faceplate with the
controller exhibiting this condition. If condition does not occur, then replace the
Hunter ICC faceplate. Underhill also offers the Sapien 2Wire controller as a suitable
replacement. In either case the decoders attached to valve zones
do not
require
reprogramming.
Observed Field Condition
14) “I’m new to this site and there are no “As-‐built” drawings denoting the valve
locations. I can’t locate or irrigate some stations. Will a cable detector I use to locate
wire for a multi-‐wire controller work to locate the 2Wire path?
Solution
Generally speaking no, multi-‐wire cable detectors typically generate 500V pulses. As
almost all lighting protection modules start to conduct at 90V, these will prove to be
ineffective and are not recommended.
Another type cable locator that generates 20-‐50V at a higher frequency are better
suited for locating the 2Wire path. The
following two web links meet these
requirements as suitable alternatives. One of them might be available for rental
depending on the size of the metropolitan area where you live or conduct business.

Another alternative is to contact a local cable locating service to determine if they
have similar equipment that could be applied.
