ProtEX-MAX PD8-6060 Explosion-Proof Dual-Input Meter Instruction Manual
22
Setup and Programming
The meter is factory calibrated prior to shipment to read
in milliamps and volts depending on the input selection.
The calibration equipment is traceable to NIST
Overview
There are no jumpers to set for the meter input selection.
Setup and programming may be done through the infrared through-glass SafeTouch buttons, or using the
mechanical buttons when uncovered. There is a slide switch located on the connector board. This is used
to enable or disable SafeTouch Buttons.
After power and input signal connections have been completed and verified, apply power to the meter.

Buttons
The ProtEX-MAX 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 DISABLE on the switch labeled NO-CONTACT
BUTTONS located on the connector board.
To actuate a button, press one finger to the glass directly over the marked button area. Then retract finger
more than three inches from the glass before pressing the next button. 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.
The SafeTouch Buttons are configured by default to duplicate the function of the front panel mechanical
pushbuttons associated with the integrated meter. The symbols by each SafeTouch button correspond to
a mechanical button as shown in the table on the next page.
SafeTouch 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.
WARNING
Take caution when cleaning the window glass as it may result in
unintentional SafeTouch button events. Only clean the ProtEX-MAX
when the system is safely shut down, and inspect the ProtEX-MAX
for proper configuration prior to system restart.
