KH Director when testing causes pab comm error.

Hi

The KH director is second hand but detects fine and I can calibrate. The doser is slave 2.0 and works fine. Both are running of a Profilux 4 to control them. When ever I either try to do a manual KH test or a scheduled test I get a lot of pab alarms. The unit alarms and the resets and does this through the test. Sometimes the test still works othertimes I get a Triation error for the test. Any guesses as to what going on? Is the director faulty?

KH director firmware 1.0
Dosing pump 2.0 firmware is 1.36
Profilux 4 firmware is 7.24 from memory. One before current version in latest control software.

Thanks
