Introduction
The BERT-E is a rugged, explosion-proof, pulse input rate/totalizer for demanding applications in
hazardous areas or in harsh environments. It can be programmed using the four through-glass buttons,
without removing the cover, or with four internal push-buttons. The top numeric display will read rate or
total up to five digits and the alphanumeric bottom display will read up to 7 digits, 13 digits with the total
overflow feature. The alphanumeric display can also be programmed to show any combination of
numbers and letters up to seven characters long for rate, total, grand total, engineering units and/or

The BERT-E is equipped with four sensors that operate as through-glass buttons so that it can be
programmed and operated without removing the cover (and exposing the electronics) in a hazardous
area. These buttons can be disabled for security by using the THRU-GLASS BUTTONS switch and
selecting the OFF setting. This switch is located on the back of the removable electronics module.
Through-Glass Button Operation
To actuate a button, press and remove one finger to the glass directly over the marked button area.
Remove finger to at least 4 inches away from the glass in between button activations. Through-Glass and
mechanical buttons may be held to cycle through menus or digits in place of repeatedly pushing a button.
Through-Glass Power Save Mode
Through-Glass buttons enter a power saving mode after three minutes of
inactivity. This mode is indicated by a pause symbol ( ) appearing in the lower
right of the display. Only the MENU button is monitored in this mode. To activate
the Through-Glass buttons, press and hold the menu button for up to five
seconds. The display will read AWAKE, and the Through-Glass buttons will be
fully enabled.
Through-Glass Disabled Mode
When the cover is removed, the four mechanical buttons located next to the
sensors may be used. The sensors are disabled when a mechanical button is
pressed and will automatically be re-enabled after 60 seconds of inactivity. The
Through-Glass power symbol ( ) will blink in the lower right of the display if the
buttons are disabled due to a mechanical pushbutton being pressed.
!
IMPORTANT
Through-Glass buttons will not work if two or more buttons are
detected as being pressed simultaneously. As a result, be careful
to avoid triggering multiple buttons or reaching across one button
location to press another.

Through-Glass Button Tips and Troubleshooting
The Through-Glass Buttons are designed to filter normal levels of ambient interference and to protect
against false triggering, however it is recommended that the Through-Glass Buttons be turned off (slide
THRU-GLASS BUTTONS switch to OFF) if there is an infrared interference source in line-of-sight to the
display or if the buttons are not needed.
Through-Glass Button Tips:
To the extent possible, install the display facing away from sunlight, windows, reflective objects and
any sources of infrared interference.
Keep the glass window clean.
Tighten the cover securely.
Use a password to prevent tampering.
If the cover has not been installed and secured tightly, it may take a moment for the Through-Glass
buttons to properly self calibrate when the cover is tightened.
After all connections have been completed and verified, connect the ribbon cable to the display module,
fasten the display module to the base, install enclosure cover, and then apply power.
Through-Glass Button Equalize Delay
The Through-Glass buttons are designed to constantly recalibrate for ambient
conditions. When the cover position is changed, the cover is removed, or an
object is removed that was placed over the front window, it may take a moment
for the Through-Glass buttons to recalibrate to the change in conditions.
Allow up to 2 minutes for the Through-Glass buttons to recalibrate to new
conditions in these cases where the cover position was changed, or the front
window is being unblocked.
