SafeTouch
®
Buttons
The PD6830 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
selecting the LOCK setting on the switch located on the connector board in the base
of the enclosure. To actuate a button, press and remove one finger to the glass
directly over the marked button area. When the cover is removed, the four
mechanical buttons located next to the sensors are used. The sensors are disabled
when a mechanical button is pressed and will automatically be re-enabled after
60 seconds of inactivity.
The SafeTouch
®
Buttons are designed to filter normal levels of ambient interference
and to protect against false triggering, however, it is recommended that the
SafeTouch
®
Buttons be disabled (slide switch to LOCK) if there is an infrared
interference source in line-of-sight to the display or if the buttons are not needed.
SafeTouch
®
Button Tips:

To remove cover with power applied (safe area only), or to clean the window,
select
CLEAN from the SERVICE menu before opening the cover or cleaning the
glass. This will temporarily disable the SafeTouch
®
buttons for 60 seconds to
prevent inadvertent use. Use the mechanical buttons while the meter is open.

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.
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.
