We noticed that the Setpoint contact of several (so far 8 out of 14) IPCMini opens for some minutes every 32 days, although the current is well below the Setpoint. Is this a software bug?

I just received confirmation that you may be correct, and a revision is in progress.

Thank you. Recently, we noticed something like the "next level".

Two of our IPCMini were delivered approximately 2 years ago.They have a higher number of opertional hours.

Serial IT1841C146 and IT1835C518.

Since this monday 10th May, they show an open SetPoint although the current is well below the set value of 10uA.

Now it is wednesday 12th May and still the contact is open.

So the behavior seems to depend on the total operating hours.

We see the effect in pairs, because we use a set of 2 IPCMini for each Thales Klystron, and operate them manually at nearly the same time.

Thank you, I forwarded your additional information along to the appropriate channels.

Thank you. While we're at it, there is another issue.

The scaling of the IPCMini analog output can be set from menu.

If the 230V power is cut and restored, the IPCMini will remember these 2 set values of the output scaling. Good.

However, if somebody checks these values anytime after boot and presses "confirm", then these 2 values are set to zero.

Thus, a second checking of the values reveals this.

Here is a more detailed information as "picture story" combined with measurements as PDF from Klystron #8 from Thales.
