Four Obstacles You May Face When Tending to Your Aging Paperless Recorder

Written by: Dan Weise

It’s been about a decade since the Honeywell Trendview X-Series paperless recorders were first introduced. And as with any product, you can expect some routine maintenance and service requirements that come with age.

We’ve put together four obstacles you may face when tending to your aging paperless recorder, and how you can overcome them to further maximize the lifespan and functionality of your device.

1. Changing the Clock Battery

Clock Battery.jpgIf your paperless recorder is getting old, the battery may be ready to be swapped out. Your recorder uses a standard CR2032 lithium battery that is both inexpensive and readily available at most drug stores.

Although this appears to be a simple solution,  I’ve noticed when I change out the battery, the system resets the clock to January 1, 2003.

If you have standard, or no security enabled, you can simply login and change the time. However, this can pose a problem if your recorder uses the ESS extended security (usually a pharmaceutical requirement). When an ESS-enabled recorder resets back to Jan 1, 2003, no user, not even an administrator, can get access to the setup because the valid period for all passwords appears to have expired.

In order to avoid this problem, it is best to plan ahead before attempting to replace the clock battery.

Honeywell can generate a one-day-use access code for January 1, 2003, and another code for the actual date you plan on changing the battery. This will give you access to the passwords section, so an administrative user’s password can be reset, or an additional administrative user can be created.  (I prefer to create an additional administrative user.)

Once an administrator has access, the clock can be reset.   Of course, that locks out the newly created administrator, but the regular administrator should have access at that point.

Why Disable a Channel on a Honeywell Paperless Recorder?

Written by: Dan Weise

Over time, changes in your process needs occur, and a sensor you’ve connected to a Honeywell paperless recorder channel may be taken out of service. When this happens, I suggest that both the analog input and the pen be disabled. Here’s why:

Changing the Clock Battery on a Honeywell Paperless Recorder

Written by: Dan Weise

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!

Download Remote Viewer Windows Application for Honeywell Trendview Paperless Recorders

Written by: Dan Weise

One of the strongest attractions of the Trendview paperless recorders has been the ability to check the recorder screen from a desktop without having to be in front of the recorder, what Honeywell calls ‘Remote View’.

For over a decade, users have been able to use their company’s installed network infrastructure to view data on one or more recorders from their desktop using Internet Explorer (IE). That worked great until Internet Explorer 11 abandoned ‘Active-X’, the component used to update the browser display.

For anyone using Internet Explorer 11, the alternative is a free Windows software application, Remote View Windows, that does exactly the same thing as IE did – it displays a Trendview recorder screen and keeps it updated. It replaces the remote view function formerly done with the Internet Explorer browser and the now unsupported Active-X in IE 11.

Using a Honeywell Paperless Recorder as an Alarm Annunciation Panel

Written by: Dan Weise

It’s surprising to me how many Honeywell Trendview recorders are used primarily for alarming. People tell us that they like the alarm screens on the old-style annunciation panels. On a digital recorder, they look like this:

Users say “It’s easy to tell at a glance, which points are in alarm because the red really stands out. And the process values show up right there under the tag. Everything we need is in one place”

Why doesn’t the print button work in my Trendview recorder browser window?

When their Remote View option is turned on, Trendview paperless recorders display recorder screens in Internet Explorer as shown here:

Trendview Post

Getting a printout was not as easy as using file > print, because the technology uses Active-X components in Windows, so the result is a blank screen; something to do with Active X and printing.

How far does playback go on a Honeywell paperless recorder?

The two most common questions I get about paperless recorders are:

  • How far back in time can I scroll back or playback the chart?
  • How many days/weeks/months of data does the recorder save?

What people don’t realize is that the answers to these questions vary according to how the recorder’s memory is allocated.

To help you understand how the recorder’s memory works, let me explain how data is viewed and saved on a paperless recorder.
