The installed base of Honeywell Trendview X series paperless recorders is approaching an in-service period of a decade (introduced mid-2006). Given that kind of service time, you need to be aware of the issues involved in changing the clock battery.
The replaceable clock battery serves as a backup for the on board real-time clock chip as well as the internal battery-backed static RAM. If your paperless recorder is getting old, the battery may ready for a swap-out. If so, you may need a one-day-use access code that only Honeywell can provide, so plan ahead. You don’t want to get locked out of your recorder!
When you’re dealing with process recorder functions, some actions don’t like negative values, like a totalizer that sees a negative offset at zero flow as backflow, which impacts the total. But on the Honeywell X-Series paperless recorders, you can work around the issue, so they report only the positive values.
